Data Centre Proposition

IntroductionThe growth of data The creation of data has accelerated dramatically in recent years and is likely to continue to grow rapidly in the next decade. Companies, organisations and individuals, are creating vast amounts of data every second about their businesses, customers, operations and personal lives. It is estimated that 90% of the world’s data was created in the last two years1, and each day 2.5bn gigabytes of data is created – enough to fill over 27,000 iPads per minute2. Millions of networked sensors have been embedded in the physical world in devices such as mobile phones, smart energy meters, automobiles, and industrial machines that sense, create and communicate yet more data in the age of the Internet of Things. It has been suggested that this could mean that by 2020 sensor data will be created by as many as 50bn connected devices across the globe3.

Data has been likened to the “new oil” of the 21st century4, and is therefore a driver of growth as business sectors across the economy are being transformed by data, analytics, and modelling as described in the UK Government’s Information Economy Strategy5. There are several important themes that are driving the growth, use and significance of data:

Cloud Computing – The growth of cloud services and storage has been driven by cost reduction and scalability. For large organisations storage of data virtually is the only cost effective solution; for small and medium sized enterprises (SMEs) the ability to use cloud services and storage allows these companies to grow without having to invest in large IT capital expenditure which traditionally has inhibited growth. Furthermore the availability of cloud-based solutions has dramatically lowered the cost of storage, which has led to more UK companies being able to work with big data analytics6.The implementation of the G-Cloud framework and Cloudstore7 in the UK has driven the growth of cloud service adoption in the public sector, allowing more companies to participate in this market than ever before8.

Big Data Analytics – Big data refers to datasets whose size is beyond the ability of typical database software tools to capture, store, manage, and analyse. Big data in many sectors today will range from a few dozen terabytes to multiple petabytes (thousands of terabytes). Big data analytical tools (analytics) are being adopted by both large companies and SMEs across all sectors; 85% of Fortune 500 companies are expected to implement the technology in next 2 years, with widespread adoption of big data analytics by 20179. Big data has been defined as one of the UK’s “Eight Great Technologies” strategic areas by the Department of Business, Innovation and Skills, illustrating the Government’s commitment to this area10. It is estimated that the big data market will benefit the UK economy by £216bn and create 58,000 new jobs before 201711. NESTA has shown that UK data-driven firms are 40% more likely to report launching products and services ahead of their competitors than those who aren’t data-driven firms12. NESTA also shows a strong connection between online data use and a firm’s productivity and profitability.

Internet of Things (IoT) – According to Gartner the Internet of Things will profoundly transform the data centre market, its customers, suppliers, technology and patterns of sales and marketing; it is estimated that the IoT installation base will increase to 26bn by 2020 and the connected devices will spread to the entire globe13. IoT deployments will generate large quantities of data that will need to be processed and analysed in real time; this activity will increase as a proportion of the overall workloads of data centres, leaving providers facing new security, capacity and analytics challenges. IoT product and service suppliers will generate incremental revenue exceeding $300bn, mostly in services14.

Smart Cities – the worldwide evolution of cities from urban settlements to Smart or Future Cities is accelerating driven by expanding populations, the desire for individuals to live in cities and the pressure on resources. An OECD report forecast that 70% of the global population will live in urbanised areas by 205015. This evolution is enabled by both the Internet of Things and Big data analytics, which in turn drives the creation of yet more data and increased need for and dependency on data centres; this presents a challenge and an opportunity. It has been stated that if cities do not invest in scalable and flexible data centre infrastructure and focus on managing their data traffic, then it could lead to severe outages or failure of services on which the population has become reliant16. However the UK is actively engaged in the development of Smart City technologies and the creation of a number of cities to act as test sites for these products and services as discussed in a recent Department of Business, Innovation and Skills report17. The Future Cities Catapult has been set-up by the Technology Strategy Board with support from industry representing an investment of up to £150m18. It will focus on bringing together cities, companies and academics to develop new commercial solutions for integrated city systems, much of which will be driven by the Internet of Things and big data collection and analysis19.

With such strong growth of data globally, the need for data storage and the ability to transmit and manipulate data on an on-demand basis is also increasing considerably. This need is being met by the provision of data centres: according to the research group Gartner, global spending on data centres would be $143bn in 2013, and $149bn in 201420. Data centres have become critically significant for the majority of businesses and individuals alike - in the UK this represents a major market opportunity.

What is a Data Centre ?Today, data centres are the key infrastructure that all citizens depend on for their very economic and social well-being. Therefore, Ddata centres lie at the heart of the operations of all companies where all ICT, communications, data processing, storage and management is critical to their success; in practical terms this means nearly ALLall businesses. A data centre contains the hardware and telecommunications infrastructure to provide an environment which is safe, secure and stable. It is carefully monitored to ensure consistent supply of fundamental facilities such as fibre connectivity, power and cooling. The 2 key size measures for data centres21 are

Number of racks which hold the servers and other equipment that underpins thesupports data storage digital services.

The amount of “white space” which is the portion of the data centre used to house the racks, servers, networking and other IT equipment. This does not include areas where cooling, power protection or distribution equipment is housed (which is known as grey space)

The key measure of data centre operational efficiency is its Power Usage Effectiveness (PUE) which is the measure of how efficiently a data centre uses its power. The PUE represents how much of this power is actually used by the IT equipment, in contrast to power used by cooling, lighting and other additional plant within the data centre:

PUE = Total Facility Power/IT Equipment Power

Data centres with low PUE are considered to efficient, and will have low costs associated with running the facility (relating to cooling, lighting…), whereas data centres with high PUE, have higher running costs22.

There are 5 different sizes of data centre facility which are characterised by the number of racks, space occupied and power consumed and defined as follows23:

Type Number of racks Area (m2) Total power consumption (kW)

Server Room <20 <100 <100Micro 21-50 101-250 101-250

Medium 51-200 251-1000 251-1000Large 201-500 1001-2500 1001-2500Mega >500 >2500 >2500

In most instances the term data centre refers to the larger facilities that have been purpose-built by companies for their own use or developed to provide datacentre infrastructure and services for other companies.

Users will require different levels of security depending on the sector and application; 4 tiers of security have been defined by the Telecommunications Industry Association24 using a number of criteria including availability and annual downtime as follows25:

Tier Classification Availability (%) Annual downtime (hours)

1 Basic 99.671 28.82 Redundant Components 99.741 223 Concurrently Maintainable 99.982 1.64 Fault tolerant 99.995 0.4

Tier 1 is defined as essentially a server room with only basic redundancy and security standards, whereas tier 4, which is designed to host the most secure and critical systems with the very highest levels of security and redundancy. When a data centre provides shared services to many clients it’s known as a Colocation or Colo.

The UK has a world class data centre industry, providing an ideal mix of service provider options such as commercial data centre space or hosting (colocation), managed and cloud services, as well as a global reputation in design, construction and operation of data centres.

Market Opportunity The UK’s well established and mature data centre market offers a world class blend of specialised skills, an experienced supplier base, strong and proven market demand and a stable and business friendly environment. The UK is the largest data centre market in the Europe with 2.9 million m2 of white space which corresponds to just over 27% of the region’s capacity26. Across Europe approximately 56% of white space belongs to companies whose data centres are global in scope. White space across the region is projected to increase by just over 1% per annum until 2016. UK data centres have approximately 1,080,000 racks which represents 28% of Western Europe’s capability; this reflects an annual growth rate of 3.8% since 2011 and predicted growth of 3.4% annually to 2016. Colocation companies, the finance sector, IT services and the telecoms & media sectors own and/or operate the highest number of racks; highest growth in the number of racks since 2012 has been in the professional services sector.

Investment in data centres can be divided in to three broad categories:

1. Colocation & outsourcing services: includes retail colocation, wholesale colocation, hosting, managed services, IaaS, PaaS and SaaS

2. Facility equipment and solutions: includes cabling and switching infrastructure, power protection equipment, cooling infrastructure solutions, power distribution solutions; monitoring systems, power distribution systems, data centre infrastructure management (DCIM), modular solutions and containerized solutions

3. IT optimisation strategies and solutions: includes server virtualization, application virtualization, user virtualization, cloud infrastructure architectures, network and routing equipment upgrades, storage systems upgrades, systems management upgrades, data centre automation software, blade servers, high performance computing, unified computing, mainframe computing

In Colocation & outsourcing services, the UK is the second largest market in the world (after the US)

valued at $3.79bn in 2012/13 which represented growth of 11.5% year on year; projected growth in this category is expected to be 8% for the whole of Western Europe of which the UK is the most significant component. In Facility equipment & solutions the UK is also the second biggest market (after the US) valued at $5.8bn in 2012/13 with a similar position for IT optimisation and solutions valued at $5.91bn, which taken together represents 36% of Europe’s total investment. European growth was 7.4% year on year and projected growth in this category is expected to be 4.8% in 2013/2014 leading to a corresponding total European investment of £33.5bn. In 2012/13 the combined investment across all three categories was valued at $15.5bn second only to the US27.

According to the AMA Data Centre Construction Market Report - UK 2014-2018 Analysis28 it is estimated that cooling and air conditioning equipment within data centres is worth around £263m at installed prices per annum, while the market for data centre construction was estimated to be valued at around £1.1bn in 2013, following two years of high level growth29. Power consumption from Western European data centres in 2013 was 11.78GW of which the UK was the largest component at 3.1GW (26%)30.

Attractiveness of the UK as a destination for data centres It is not just the size of the UK’s data storage digital services market which makes it a global competitor. In 2013, the UK was named the second lowest risk destination in the world for data centre locations31 and the UK is also positioned fourth in the overall Data Centre Development Index (DCDi), which ranks markets according to their state of development32. This ranking is predominantly due to the UK’s high internet bandwidth capacity and a high rating for the ease of doing business. Achieving an increase in energy efficiency is important as energy costs are estimated to comprise between 25% and 60% of data centre operating costs33. Through increases in energy efficiency, data centres can achieve greater effectiveness as more work is done per unit of energy used; a selection of UK research in this area is given below.

The UK is a location of choice for data centre providers as it scores highly on many of the following criteria:

PowerData centres have high power consumption requirements, so stability of power supply is a critical decision factor. Unexpected power outages and fluctuations which are common place in many parts of the world and are incompatible with the efficient running of a data centre. Fortunately the UK has stable affordable power supply and an excellent track record for consistency of supply. The UK’s data centres have an outstanding record of continuous energy monitoring at 80% second only to Japan34.

Cooling and Climate

Data centres generate large amounts of heat so efficient cooling is important for keeping operational costs low. Data centres built in cooler climates can reduce costs because outside air can be used to chill them. The UK climate is temperate, with limited highs and lows and a low average temperature across the year compared to many global locations. So the UK environment is ideally suited to energy efficient data centres, and is further supported by R&D focused on technology to improving energy efficiency (see below).

Connectivity For the majority of sectors, the time taken to access data (latency) is very important to a company and in some cases it is business critical (e.g. financial services). In the UK there are many data centres that are located close to end users and also those that are in more remote locations but with very good connectivity reflecting the diverse range of options that are on offer. With three Internet Exchanges (London, Manchester and Leeds), the UK has excellent connectivity to the rest of the world and is truly the digital gateway to Europe and global markets.

Optical Fibre infrastructureIn England the network structure is largely received from 4 input areas: the North East, North West, London/South East and most notably the South West35. The landings in the North of England are linked to Scandinavia, Northern and Republic of Ireland and Europe; the highest amount of cables land in the South West, as they link with the Americas and are the primary location for cables transferring to the rest of Europe and Asia. In Northern Ireland the optical fibre Network is mainly driven by Project Kelvin from Hibernia and also from the CeltixConnect cable. Project Kelvin36 is an extensive submarine and terrestrial cable deployment that directly connects Northern Ireland to North America. In Scotland there are direct links to Scandinavia, Iceland and North America37. In Wales the Carrier Wales Network is driven mainly driven by the Manchester Gateway; the Superfast Cymru connect network, which is based in South Wales, is driven by cable landings in the South West of England38.

Proximity to riskData centres aren’t indestructible. Building them on fault lines, on flood plains, below sea level, or in the path of air traffic creates unnecessary risk for the facility. The UK has an extremely stableenvironment with limited extreme weather conditions and natural disasters. The Global Seismic Hazard map39 shows the UK is one of the lowest risk regions in the world for seismic activity.

Data securityPrivacy concerns and compliance regulations require that certain types of data (in particular, customers’ personal data) be stored within the region or nation in which it is collected. Political instability also causes concern regarding data security. The UK has a strong history of economic and political stability dating back many hundreds of years. It has a proud track record of business friendly and pragmatic policy in this area (see also Policy section below)

Opportunity by sector With the growth of data generation, analysis and storage in all sectors, opportunities exist across the data centre supply chain for both SMEs and larger companies:

Finance

Advanced business modelling and the development of big data analytical tools is revolutionising this sector leading to increased demand for low latency data centre provision to support innovation and optimisation and the upgrade of legacy systems.

Internet hosting and online retailThe UK is the biggest E-Commerce market in Europe and has a rapidly developing M-Commerce market, leading to rapidly expanding demand for cloud based services and data storage.

HealthcareWith an environment of open data, electronic health records and significant investments in digital health technologies especially in big data analysis, there is significant growth in the need for data centres to support this sector .

ICTThe growth in cloud services, mobile apps and real-time analytics has led to rapid growth in this sector driving growth in data centre provision, which is likely to accelerate as more businesses realise the value of big data analytics in areas like Smart Cities.

Industrial manufacturingThe growth of advanced manufacturing and the proliferation of the Internet of Things have created a much more data intensive landscape in UK manufacturing which in turn has accelerated the need for data centres to support this sector.

Creative Industries The amount of digital content created and consumed in the UK has exploded in recent years. The requirement for instant access and download particularly for video content has led to a dramatic increase in demand for accessible and affordable data storage.

Public Sector The UK has pioneered the implementation of an e-Government strategy as exemplified by a pan-departmental web presence (www.gov.uk), a digital marketplace for cloud service provision (G-Cloud / Cloudstore) and an open data philosophy. This has led to a streamlined approach to data centre provision and many opportunities for large and small companies to participate in the delivery of digital services for the citizen.

Policy DevelopmentsData protection and data privacyIn today’s business environment, a company’s data can be created, stored and manipulated in several countries which present challenges to companies and individuals alike. In the UK the key legislation is the Data Protection Act, which defines how data is to be managed, and the rights and responsibilities of both companies and individuals. Data privacy is a core aspect of European law and as such is culturally embedded into the mind-set of European businesses and citizens. This is in contrast to many markets around the world, where data privacy is treated differently. The UK has taken a pragmatic approach to the application of the EU regulation which continues to evolve and has created an environment that is less restrictive than most European markets. The Safe Harbour

framework is an excellent opportunity for US companies to prepare for entering the UK and European markets and meet the data privacy requirements.

The Data Privacy Index, from information law portal Data Guidance40, calculates a risk score for each country based on the severity of its data protection regime – a high risk means there is high chance of breaking the rules and of being punished. According to the index the UK is ranked as having the 21st strictest data privacy laws in Europe. This means that the UK is more lenient, in terms of data protection, than France, Germany, Spain, Norway, and Italy, whilst Ireland, the Netherlands, and Sweden were ranked as equal leniency to the UK. "The UK Information Commissioner does not have a legal right of audit but does ask companies to voluntarily subject themselves to audit," the index reported. "The UK privacy regime has focused on persuasion rather than punishment to achieve greater data privacy compliance. In France, Germany and Spain and other mainland European countries there has been a more aggressive approach to enforcement. The UK approach is viewed as more flexible, encouraging technological innovation, greater use of cloud computing and as being more in tune with the global flows of data“.

StandardsThe UK has taken a strong role in leadership on establishing data centre standards, industry development and project management. The Data Centre Alliance based in the UK but with an international membership has established the DCA Certifications Scheme41 which is a harmonised set of standards that when applied to a data centre identifies its resilience class, site physical security, energy efficiency strategy and operational professionalism.

Energy Data centres are one of the fastest growing energy consumers in the IT industry. As data centres continue to grow, their power and resource consumption will increase dramatically. Even with the latest virtualisation and cooling technologies, the draw on total UK power will be significant.It is currently estimated that data centres consume between 2.4-3.1% of total UK energy42. The Carbon Reduction Commitment legislation has had a positive effect in getting UK companies to focus on their data-centre energy consultation.

Climate change agreement The recently implemented Climate Change Agreement (CCA) 43 grants a concession for the UK’s data centre industry creating a more attractive and competitive environment, by reducing taxes on the sector, in exchange for meeting agree efficiency targets. CCA’s have been designed for industry sectors, such as manufacturing, which use large amounts of energy, but have recently been extended to the data centre industry. Under the CCA, the sector agrees efficiency targets, at levels where the cost won’t make the businesses uncompetitive. There are around 50 CCAs in operation, but the data centre industry’s is the first CCA in a sector which does not manufacture physical objects. The benefits of having a CCA and partaking in the Climate Change Levy (CCL) Discount Scheme result in up to 90% discount on the CCL charged on energy bills in return for meeting energy or carbon saving targets44.

Enhanced Capital Allowance (ECA) scheme45

This scheme is a key part of the Government’s programme to manage climate change. Introduced by the Department of Energy and Climate Change it provides businesses with enhanced tax relief for investments in equipment that meet published energy-saving criteria. The scheme enables businesses to claim a 100% first year capital allowance on investments in certain energy saving equipment, against the taxable profits of the period of investment. The general rate of capital allowances is 18% a year on a reducing balance basis. Some technologies supported by the ECA Scheme (e.g. boilers, lighting) are included in a special capital allowances pool where the general

rate of capital allowances is 8%. A 19% tax cash credit is available for loss- making companies up to £250,000 or the company’s employment tax liabilities, whichever is less. A range of heating, ventilation, and air conditioning equipment that is listed in the UK’s Energy Technology List (ETL) qualifies for ECA.

Rich and Diverse Ecosystem

Funding agencies Technology Strategy Board (TSB) is the UK’s innovation agency and is a key funding body for technology development in the UK; it has a number of different mechanisms to support large and small companies46. Big data exploration is a high priority for TSB and is one of the key challenge areas within enabling technologies; a recent £4.5m call “Data exploration - creating new insight and value” is focused on stimulating development and demonstration of new ways to explore data to extract value from it47. Energy efficient computing is also a key priority and the subject of a recently announced £3.5m call “Scaling up Energy-Efficient Computing"48. TSB Catapult Centres in areas such as the Connected Digital Economy, Future Cities and Transportation will also be engaged with big data analytics projects, all of which will drive higher demand for data centres.

Engineering and Physical Sciences Research Council (EPSRC)49 is the primary agency for funding research and development in computer science and data science. The flagship Centres for Doctoral Training (CDTs) provide an environment for universities to work closely with industry partners on a range of topics (e.g. big data/data analytics). Their focus is industry centric, with ample opportunities for companies to participate: the Engineering Doctorate (EngD) is an alternative to the traditional PhD for students who want a career in industry. A four-year programme combines PhD-level research projects with taught courses, and students spend about 75% of their time working directly with a company. EPSRC currently has 91 CDTs across a broad range of science & technology with a further 22 to be added in 2014 representing a combined public and private investment of £950m.

Centres for Doctoral Training University of Edinburgh - School of Mathematics - CDT in Data Science50 The CDT focuses on the computational principles, methods, and systems for extracting knowledge from large data sets ranging from molecular biology to social media, from sustainable energy to health care. This multidisciplinary centre will bring in skills from a diverse range of disciplines including machine learning, pattern recognition, and analysis of unstructured data such as text, images, sensor data, video, and speech.

University of Oxford and University of Warwick - CDT in Next Generation Statistical Science51 This CDT is a collaboration between 2 outstanding statistics departments and is supporting the growing demands of measurement technology and the emergence of big data and "big models". This is the first centre of its type in the world and will uniquely equip its students to work in big data analytics, in sectors such as engineering, manufacturing, finance and e-commerce which have all become aware of the big data opportunity.

SkillsThe UK offers a range of talented people to support sales, marketing, design, construction and operation of data centres, enabling businesses to grow their workforce and UK footprint. In its recent Data Centre Census Report72, Datacenter Dynamics found that rising labour costs was a much less critical issue in the UK compared to other major European markets, and the level of skills shortages was much lower than in the majority of other markets in Europe. The UK also has the ability to draw on talent from across Europe’s 500m population, further strengthening its attractiveness as a leading technology investment destination. The UK has 4 of the world’s top 10 universities and has many other universities that have strong Computer Science and Engineering departments that are firmly focused on developing the skills that are needed for data centre design,

construction and operation. The extensive network of CDTs (see above) has created an environment for postgraduate researchers to work on business problems across a broad range of sectors ensuring their skills are consistent with industry’s needs. More specifically many universities are now offering postgraduate courses which focus on data centre construction and management, for example Leeds, Cranfield, Westminster and West of Scotland73. Knowledge Transfer Partnerships, funded by the TSB provide a further mechanism for funding technology projects which facilitate the transfer of essential skills from universities to companies via a collaborative project; in this case financial support is provided at ~50-67% depending on the size of company and the project involved.

Many universities run internship programmes in ICT and Engineering, and there are international equivalents such as IAESTE74 run by the British Council and AIESEC75 that facilitate internships in the UK for overseas students. There are many intern agencies to assist companies that are trying to find the right ICT and Engineering skills such as Enternships76 and Work in Start-ups77, and initiatives such as Silicon Milkroundabout78 which is an employment fair organised by the SME community in Tech City to assist other companies to recruit developers and analysts. Other schemes such as the EU Marie Curie79 and Erasmus80 programmes also facilitate the mobility of technical skills across Europe. The UK Government runs an extensive apprenticeship programme which assists companies to find individuals that can be trained in-house, where a significant part of the cost is met by the programme81. The scheme focuses on young people (16-25 years), but there is a higher level digital apprenticeship scheme targeted on developing digital skills for the ICT sector82.

A number of data centre operators have established facilities in this area which has very low latency and close proximity to London’s financial markets and creative industries

Thames ValleyJust to the west of London and close to Heathrow airport this region has the highest concentration of data centres in Europe. There is a dense fibre network linking the UK and USA via multiple fibre suppliers providing low latency and plenty of room for expansion. Global data centre operator Equinix, recently announced the construction of its 6th data centre at its Slough campus in response to consistent demand from customers in the financial services, content, cloud and enterprise segments83. The Thames Valley boasts the headquarter operations of many multinationals including Oracle, Microsoft, Dell, Computer Associates and Vodafone.

ManchesterThe city has a strong creative and digital ecosystem underpinned by the presence of global broadcasters and content creators. International healthcare companies offer opportunities around medical technologies, telemedicine and eHealth. With a superfast telecoms infrastructure the region has attracted may international investors: IBM, Microsoft, Oracle, Cisco, Fujitsu, CGI, BT and Sunguard have all invested in Manchester. One of the biggest concentrations of computing talent in Europe can be found around Manchester’s universities. More than 5,000 computing graduates each

year are fuelling the growth of the ICT sector, and includes 50,000 IT workers in the city and a further 50,000 in the wider region. Substantial areas exist with the potential to house new design-and-build centres, with modern fibre networks and legacy power supplies that can accommodateData centre requirements.

Leeds (Yorkshire)A major internet exchange is located at Leeds and the surrounding region of Yorkshire is home to many data centres. There is a strong talent pool in this region and the University of Leeds is a global leader in data centre engineering. Leeds is also the UK's main financial and business services centre outside London which drives the need for data centre infrastructure. Companies that have located their European shared service centres here include Aetec, Scientific Games, General Electric, IBM, British Waterways and the NHS.

WalesEurope’s largest data centre is located in Newport in South Wales, operated by Next Generation Data. There are nearly 3,000 ICT operations in Wales – among them Fujitsu Services, BT, Mitel, Logica, Cassidian, General Dynamics UK, SAIC, Sony UK, Logica and IBM, contributing around £1bn to the Welsh economy annually. The Welsh Government is seeking to ensure that 96% of all premises in Wales will have access to Next Generation Broadband by 2016, with many premises able to access speeds of over 100mbps.

ScotlandMany companies have chosen to set-up their data centres in Scotland including JP Morgan, HP and IBM. Scotland provides affordable energy and with an average temperature 2°C lower than mainland Europe, the cooling and operational running costs are much lower than many other regions. Edinburgh University is home to the largest Informatics Department in Europe and has a centre of excellence in data science.

UK Market SuccessNTT Communications84

In September 2013 Gyron Internet Limited (an NTT Com group company) announced the construction of a new 30MW data centre at Hemel Hempstead, which will be known as “The Campus”, to meet the growing demand for scalable and reliable colocation services. Located at a 9.5 acre (38,500m2) site near two existing Gyron data centres in Hemel Hempstead, northwest of London, the new facility will start providing approximately 10,000m2 of server room from spring 2015, expanding NTT Com’s total server room area in the UK by 2.5 times.

By using advanced green technology for cooling, such as end wall injection air conditioning, water-side economization, and chimney racks to expel heat, the facility achieves a power usage effectiveness (PUE) of under 1.2, putting it among the most energy efficient data centres in the UK. It will also be the first large scale commercial colocation data centre in the UK to offer the option of a chillerless cooling system, which opens up approximately 30% more energy capacity for ICT systems without expanding its power system and without introducing outside air in to the server room. The facility further reduces NTT Com’s environmental load by using rain water in the air conditioning, generating electricity from solar panels, and using heat from the server equipment to warm office areas in the winter.

The high-speed, high-quality networks connecting the new facility with other NTT Com data centres will enable the low-cost, low-latency access necessary to effectively provide a hybrid cloud environment that combines on-premise systems, colocation and NTT Com’s Enterprise Cloud to

better meet varied customer demand and optimize ICT systems. In addition, the high-speed connections between Gyron’s three Hemel Hempstead data centres and two Slough data centres will allow them to operate essentially as one data centre, making it fast and easy to provide more server equipment and virtual servers for customers expanding their business. Salesforce85

In 2013 Salesforce announced it had signed an agreement with NTT Europe, a wholly owned subsidiary of NTT Communications, to establish a European data centre in the UK. Scheduled for completion in 2014, the new data centre will be salesforce.com’s sixth worldwide and will support the company’s cloud computing services across its growing customer base in Europe, Middle East and Africa. “Europe was salesforce.com’s fastest growing region in our fiscal year 2013, delivering constant currency revenue growth of 38%,” said Marc Benioff, Chairman and CEO, salesforce.com. “We are doubling down on Europe with the announcement of our new data centre in the UK, which will support continued customer success in EMEA.”

“We welcome the decision by salesforce.com to locate its European data centre in the UK. This significant development further endorses the U.K. as one of the world's greatest technology centres,” said Stephen Kelly, Chief Operating Officer for Government. “The UK is in a strong position to support fast-growing international companies such as salesforce.com in delivering innovative social, mobile and cloud services to customers here and globally.” “NTT Europe is proud to extend its partnership with salesforce.com by supporting its enterprise cloud computing services in EMEA,” said Robin Balen, Managing Director of NTT Europe's Wholesale Data Centre Business. “Powered 100% by renewable energy sources, salesforce.com’s data centre in the UK will deliver an environmentally friendly and highly resilient facility for its customers in the region.”

KDDI Telehouse86

Telehouse has recently opened a new 1000m2 colocation floor of its flagship London Data Centre: Telehouse West. It had pre-sold over 1,300m2 to a number of well-known multinationals within the telecommunications and media industry when it first opened in 2010. The success of the Telehouse West project has seen accelerated sales bring forward future plans by three years. Telehouse has taken a phased approach to selling its five floors of customer space, opening a new floor on average every 18 months. Telehouse West offers power capacity between 2 to 10kW per rack over shared, dedicated, cold aisle containment and high-density hosting areas. Since opening the 5,000m2 colocation facility Telehouse, led by its parent company KDDI Corporation, has expanded its footprint in Europe and its local services to support clients in managing their data centre through newly improved migration, system integration and hardware solutions. Michelle Reid, Sales and Marketing Director, commented “Telehouse West has been our most interesting project to date. It represents a dramatic change in our customer profile since the beginning of Telehouse North 24 years ago. From dealing with traditional European ISPs and carriers to global cloud and social media companies reflective of today’s internet. As the pioneering colocation provider we have managed to remodel our product strategy to serve a highly diverse, network-rich customer base.”

KDDI is to invest a further £135m into Telehouse’s London Docklands data centre campus: North Two has been created with the New Internet in mind. It will house mission-critical infrastructure, which will enable the development of hybrid services for customers.

IBM87

SoftLayer, an IBM Company, recently announced the opening of a new data centre in London. It will be the latest of 15 new data centres that IBM plans to open as part of a $1.2bn global investment to strengthen and extend its cloud services in Europe and around the world. The new facility will provide customers and their end users with SoftLayer services that meet in-country data residency requirements. It will also complement the existing SoftLayer Amsterdam data centre and London network Point of Presence (PoP), both launched in 2012, to provide European customers redundancy options within the region.

“We already have a large customer base in London and the region; we’re excited to give those customers a full SoftLayer data center right in their backyard, with all the privacy, security, and control the SoftLayer platform offers,” said Lance Crosby, SoftLayer CEO. “The work these businesses are doing—the solutions and services that they are building in the cloud—are inspiring. Organizations of all sizes are using SoftLayer services to disrupt their industries or even their own operations, creating new business models and applications.”

SoftLayer services will provide solutions ideal for businesses based in London and surrounding areas. The region is a key cloud market, with customers using cloud to deploy web-centric workloads or to transform their existing operations. One third of the world’s largest companies are headquartered in London and a majority of the world’s largest financial institutions have operations there. Additionally, London has one of the world’s largest communities for technology startups, incubators, and entrepreneurs. The London data centre will have capacity for more than 15,000 physical servers and will offer the full range of SoftLayer cloud infrastructure services, including bare metal servers, virtual servers, storage and networking. It will seamlessly integrate via the company’s leading private network with all SoftLayer data centers and network PoPs around the world.

Rackspace88

In 2014, Digital Realty Trust, a leading global provider of data centre and colocation solutions, and Rackspace were awarded Special Recognition for Outstanding Green Data Centre Credentials at the 7th Annual Global Data Centre and Cloud Awards. The bespoke, 12,000m2 data centre, located in Crawley, West Sussex, was designed in close collaboration between Digital Realty and Rackspace to meet the specific needs of Rackspace customers, encompassing energy consumption, availability and other design requirements. The data centre facility makes use of innovative 'indirect outside air' cooling technology, without mechanical cooling. Delivering outstanding Power Usage Effectiveness (PUE) and a design BREEAM Certified Excellent, the energy required to operate the data centre is expected to be reduced by 80%, setting a new benchmark for ‘green’ data centres in Europe. In addition, the design of the new data centre will be compatible with the Open Compute design framework changing the game in data centre operations.

“We are very proud to be involved in building one of the greenest data centres in Europe and delighted to be honoured with this special recognition,” said Gary Boyd, Senior Director, Data Centre Project Engineering at Rackspace. “Working closely with Digital Realty, we were able to factor in everything from minimising landfill and environmental impact during construction to using more efficient LED lighting and rainwater harvesting - all while delivering an exceptional data centre facility that meets the accessibility, availability and data management needs of our customers.”

“We are pleased to be recognised for our commitment to sustainable building practices and energy efficiency for this important project for Rackspace,” said Bernard Geoghegan, Managing Director, EMEA, for Digital Realty. “By collaborating with Rackspace, we were able to design and build a credentialed, next generation, ultra-efficient data centre while enabling our client to deliver cost effective cloud services to its customers across Europe.”

The Data Centre and Cloud awards celebrate the technical and commercial success of the data centre and cloud industry in Europe.

Interxion89 In 2014 Interxion as named as Colocation Provider of the Year at the Data Centre and Cloud awardsreflecting its communities focused approach, commitment to neutrality, and pledge to using sustainable energy sources. Interxion’s London carrier- and cloud-neutral data centres provide the latest highly secure, scalable infrastructure for mission-critical IT systems, with a wide range of connectivity solutions, within 6,700m2 of maximum equipable space. The data centres offers communities of interest for companies across the cloud, digital media and finance sectors. Interxion’s headquarters are located in the Netherlands.

TelecityGroup/Amazon Web Services (AWS)90

Amazon Web Services (AWS) and TelecityGroup have partnered to bring new and existing customers a more secure, reliable and cost effective way of connecting to AWS innovative cloud services via AWS Direct Connect, a private direct fibre optic connection between Amazon Web Services and a TelecityGroup data centre or corporate network. This gives low-latency cost-efficient connections into AWS via the choice of over 400 carriers connected to the TelecityGroup’s network. TelecityGroup has 7 data centres in London the majority of which are in Docklands.

NGD/Wipro91

Wipro Technologies chose NGD to host its cloud infrastructure for UK-based clients rather than looking overseas. Operating 12 data centres globally Wipro Technologies has recently expanded its UK data centre capacity by opening a private facility at NGD Europe, near Newport, Wales.This 70,000m2 mega data was built and is operated by Next Generation Data (NGD). A key driver for Wipro’s move to NGD in mid-2013 was the urgent need to service the rapidly expanding data processing, storage and private cloud computing requirements for several of its EMEA-based customers. These include Npower and Northern Gas as well as various financial services organisations.

A key driver for the move to NGD was the need for more power and scalability as a consequence ofthe growing requirement for virtualisation. While virtualisation was allowing the flexibility to changeenvironments as a customer required and in relatively short time spans, Wipro recognised theprovisioning of highly virtualised environments required access to much larger and totally reliablepower sources. Wipro saw how virtualisation required much denser IT environments and therefore more power draw per rack which, in turn, would be magnified enormously by the growing demand from customers looking to consolidate multiple data centre environments.“We had looked at building our own data centre in the UK for a number of years,” explained Roy White, Data Centre Tower Lead, Wipro Technologies EMEA, “but through investigations we came across the opportunity to be inside NGD, which has given us a different class of facility than we could have built.”

Santander92 This Leicestershire £200m project was >8 months late so probably should not be included – not clear that it has opened yet.

HP93

An innovative 28,000m2 data centre has been established in Wynyard, near Newcastle in the North East of England, designed and managed by HP. Built with energy efficiency as a primary consideration, the Wynyard data centre takes advantage of the climate in Northern England to cool

IT equipment, allowing the facility to go without air conditioning most of the year. Other design innovations and efficient HP technologies help save even more energy and resources. For example, the facility collects rain from the data centre rooftop and uses it for the humidification process, while the white-painted walls and server racks reduce the need for lighting. As a result, the Wynyard data centre is expected to reduce energy consumption by 40% versus comparable data centres of its size; each of its four server halls boasts a power utilisation efficiency (PUE) of 1.16. A breath of fresh The data centre also uses 100% wind-sourced energy, helping reduce its carbon footprint. Wynyard was selected as a winner of a prestigious 2010 Green Enterprise IT Award, presented by the Uptime Institute, and it received a 2011 International Green Award for Best Green Energy Efficiency Initiative. Wynyard is the only HP datacentre to use fresh air cooling. Maurice Julian, facilities project director at HP, says the North-East was a perfect location for this type of cooling system, due to the cooler climate compared with the South. "We took a 100-year weather report for the region. It is an ideal climate for a cool air solution."

Along with the cooler climate requirements, HP looked at a number of other criteria when choosing the location for the datacentre. "We looked at flood risk, air traffic routes, proximity to roads, ground contamination, seismic risks, terrorism and military installations." Wynyard is linked to another HP data centre, 16 miles away in Sunderland, using two diverse dark fibre routes, to provide resilience in the event that the centre goes offline.
