10 proven steps to building your next-generation data centre
DESCRIPTION
Based on the extensive experience that ANS Group have in designing, building and implementing private cloud solutions, we will share the successful techniques that will be required to build your next-generation, virtualised, service-orientated, FlexPod data centre with Cisco, NetApp and VMware technology. ANS have implemented many large private cloud solutions for organisations in the public and private sector and one of our customers, Salisbury NHS Foundation Trust, estimate that they will save £5m in the next five years after implementing our full Infrastructure 3.0 solution. By providing a virtualised infrastructure utilising technology from our three chosen vendors ANS can reduce costs and required storage space, improve disaster recovery and provide huge ROI while significantly improving the IT function of the organisations with which we engage.TRANSCRIPT

2# Standardise and Simplify
Critical Vendor Choice – Time to go Strategic….
Data Storage for a Particular Purpose (SAN/NAS)?
Multiple Points of Backup and Data Protection
Multiple Points of Management & Control
Can you Workflow, Automate and Orchestrate
so many vendor products??
Reduce the Points of Management…
3# Service Elasticity
Data and Service Mobility…
Next Generation Network Technology is helping achieve this goal (LISP/OTV/Fabric Path)…
Long Distance vMotion – Data Evacuation/Ease of Maintenance
Moving the Service is great flexibility, account for the data movement not just VM
Synchronous Technology
Great should the data restores be application consistent
A Single Virtual Data Centre….
Physically Split over 2 Locations
4# I/O Consolidation
Chassis Mgmt
Fibre Channel Blade Switch Mgmt
Ethernet Blade Switch Mgmt

FC Switch Mgmt Provide Hypervisor
Visibility and/or Pass Through
Native 10Gbps – Not for Bandwidth, I/O Consolidation and Simplification (10 Cables to 1) Reduce Modules/Ancillary Components Reduce Switchports
4#... Continued – Why?
An average input into 10Gbps blade port (based on previous) = 20723000bps 20723000bps = 20.73Mbps / 0.020Gbps / 0.0020TeGps
Cost per Connection: Blade Centre Module = £6,500 (for 8 x 10Gb ports) = £812 Top of Rack Switchport = £541 (4900M, fully populated with 24 x10Gbps ports) Cable = £70 Cost per Connection = £1,423 Power = 0.02Kw (Switch) + 0.013Kw (Module) = 0.033Kw @ 9p (Incl. Cooling) = £52 PA
Utilisation = 0.02% £28.46 is utilised, £1,394 Wasted + £51.99 Power/Cooling PA Virtualised Servers, at 10:1 Ratio = £280.46 = £1,142 Wasted
£££ Wasted I/O Costs

Some Ports @ > 10Mbps Some @ < 30Mbps
#4… Continued – Back to ‘Know Where You Are’!
Using Microsoft SharePoint as an example:
Presumptions: 2000 Concurrent Users 175KBytes page load (Microsoft published average*) Average 40 Page Loads Per Hour
175,000 Bytes × 8 = 1400000bps ×40 per hour = 56000000bps ÷3600 (sec per hour) = 15555bps ×2000 Users = 31.11Mbps
A Virtual Supervisor Switching Output (6509): (5000 User Network, 200 Site MPLS)
Port-channel1 is up, line protocol is up (connected) Hardware is EtherChannel, address is 0023.acbe.f000 (bia 0023.acbe.f000) Description: VSS link to Secondary switch <Output Omitted for Clarity> 5 minute input rate 562477000 bits/sec, 63869 packets/sec
5 minute output rate 411378000 bits/sec, 54627 packets/sec 562Mbps (Peak Time)

5# Any Protocol – Any Wire (Unified Fabric)
A Single Ubiquitous Fabric
Any Protocol, Any Wire, Any Rack, Any Server, Any VM Node
Fibre Channel, iSCSI, NFS, FCoE – (Note the increase in the use of NFS)
Next Gen Ethernet – Data Centre Bridging (DCB)
Cloud Style Infrastructure Should Provide ALL Protocols!
Typical DC ~700 VM’s > 40 Cables
Single Network/Fabric, All Protocols
6# Storage Efficiency
Data Growth
Snapshots
Raid-DP
Thin-Provisioning Thin Cloning
De-Duplication
Flash Cache
Along with obvious cost savings, storage reduction techniques provide good
operational value in a cloud style environment:
Snapshots assist instant backup and recovery
RAID-DP boosts data protection
Flash Cache provides 10x performance
Thin Cloning provides instant read only ‘0 Space’ data copies for development
Data Reduction Techniques become increasingly important…

Sometimes… We need a more ‘Business Like Way’ to present the case
Cost Per Transaction Comparison* Traditional Next Gen Infra.
CAPEX – 3 Years £1.4 Mil £900k
OPEX – 3 Years £465k £220k
Total Cost £2.795 Mil £1.56 Mil
