The Crisis
31 October 2012© Copyright Dimension Data 2000 - 20084
Every organization is under pressure to accomplish more
with less resources (financial, technologically, andhuman capital)
Many are finding that specific targets for reduction have
been set, especially in the near term
Server and storage growth do not appear to be keeping pace with economic times – in some cases, the
needs for technology are on the rise
Server sprawl continues in a lot of cases – even with virtualized servers
The impact of storage growth is stressing backup and recovery subsystems and the frequency of missed
backup windows remains for many
The typical data center will run out of power and cooling – many already have
Facilities and IT continue to struggle with an integrated capacity planning approach
Disaster recovery is something most organizations “hope” they can achieve, but wouldn’t want to test it
Each of these areas require attention, but in today’s economic times, how do you prioritize?

The Opportunities
31 October 2012© Copyright Dimension Data 2000 - 20085
Today’s economic conditions will challenge all of us to become more streamlined and efficient
Not all organizations will survive – Those that do will emerge more competitive
Doing more with less – we all should be; a lot goes to waste in the average facility - Technology, Energy,
Money
You’re not alone – waste is unavoidable under the “traditional” ways of doing things
Most realistic cost reduction targets are achievable through optimization of your data center but will also
require a transformation in how we think about the data center and IT
Collateral benefits will include:
Inherent Disaster Recoverability
Virtualization platforms are essentially DR-ready
Improved green posture and reduced carbon emissions

Virtualization is a Requirement
31 October 2012© Copyright Dimension Data 2000 - 20088
Estimates are that around 30% of servers today are virtualized, and
that is expected to grow to 50% in the near term
Virtualization isn’t new…it’s being applied more broadly and being made
available to organizations of all sizes
Organizations must continue to virtualize servers onto dense platforms in order
to curb the need for unnecessary physical space and connections (power, network, and storage)
The same base infrastructure concepts used for server virtualization will sustain desktop virtualization
Transformation to virtual desktops is a natural progression at the next refresh, for appropriate users
Average CPU Utilizationis: 3.38%
Peak CPU Utilization is:8.75%

Taking the next step, this
functionality can now span data
centers
Geo-failover without geo-clusters
Complexity of failover is
nearly eliminated
Leveraging the same infrastructure and storage functionality without extra software licensing and
other overhead
RTOs and RPOs are achieved without fully redundant servers and DR state doesn’t have to sacrifice
availability due to diminished configurations

Stationary users don’t need desktops
Desktops not only introduce additional operational requirements, they pose potential threats by
stranding critical data on unprotected nodes
Average PC acquisition with support: $1600
Average Terminal acquisition with support: $550
Leverages the same infrastructure and technology as your existing server virtualization platform – no
additional training or personnel required
Enables use of additional security and protection via use of smart cards, and limitations on what users
may copy into and out of the environment

Effective Data Management is Critical to Longevity
31 October 2012© Copyright Dimension Data 2000 - 200812
Pressure to Store More Efficiently
Data growth is exploding, primarily due to the growth of unstructured data
Having multiple copies of data is desirable
Having multiple copies of data is widely considered prudent and responsible
However…
Having an unnecessarily large number of copies of data is wasteful and
irresponsible
Lowering infrastructure costs is a necessity
Technology “Typical” Savings Resource Footprint
File-level deduplication 10 percent Low
Fixed-block deduplication 20 percent High
Variable-block deduplication 28 percent High
Compression 40 –50 percent Medium

Optimized, Protected, and Recoverable
Combining virtualization and effective data management strategies has several key advantages:
Optimization – driving up system and storage utilization increases the efficiency of electrical systems
resulting in more computing power and storage per kW of energy consumed
Protection - The inherent capabilities of virtualized resources such as portability and a perceived
stateless existence means services are not tied to single platforms and can be shifted anywhere
processing and storage are available
Recoverable – Through reductions in the amount of duplicate information stored, the amount of datato replicate for DR is reduced allowing for potentially significant reductions in Recovery Time and
Recovery Point Objectives
Green Initiatives – All suggestions thus far have the potential to slow down power requirements and
drive higher utilization of existing platforms, resulting in much higher power-to-processing efficiency

You pay for every watt, but are you actually benefitting
from each one?
In many cases, a significant amount of power that
you pay for is lost as waste heat before reaching the
data center floor
1MW Data Center - $80K/yr waste heat
4MW Data Center - $240K/yr waste heat
Efficiency for electrical and mechanical systems can
range from 65-92%

Power and Cooling Assessments are crucial to
sustainability Widespread adoption of higher density equipment will
stress power distribution and cooling systems as little as 3-
4 years old
Vertical, plenum-based cooling strategies are effective for
3-4KW on average
Inlet temperature is what you need to care about – getting
cool air where it is needed most and evacuating heat at

Adhere to International Standards Bodies
Three primary, industry-recognized bodies
Uptime Institute – www.uptimeinstitute.org
Telecommunications Industry Association (TIA) – www.tiaonline.org
Associate of Heating, Refrigeration, and Air Conditioning Engineers
(ASHRAE) – www.ashrae.org
Uptime Institute gathered data on data centers and sought to classify them intotiers (Tiers I, II, III, IV) based on availability, cost, and construction time /
complexity
Uptime’s tiering scale is globally accepted as a standard today – however actual
classification requires more detail
TIA took the Uptime tiers and added specific engineering attributes for Telecommunications, Architectural, Electrical, and Mechanical sub-tiering (TIA-
942)
Data Centers can be rated on individual sub-tiers however the overall tier is the
lowest rating
Tier classification is “all or nothing” (99.9% Tier IV = Tier III) 31 October 2012© Copyright Dimension Data 2000 - 200820

Ensure that Data Center Migration is a core business of the
partner
Dimension Data performs an average of 1.6 relocations per
week in the US alone
Verify the Transit Insurance Coverage
Full replacement value - $5MM or more
Don’t get stuck with $.60 per pound
Dimension Data has moved over $270MM in insured assets in
the last year
Most companies in the business don’t own their own trucks so
this is outsourced
Verify the transit partner’s casualty rating

Today’s economic times will challenge all of us to seek out more efficient ways of designing, building, and supporting data center infrastructure
Embracing the Journey
Maintaining and sustaining the newfound efficiencies can only result from collaborativethought and action across the organization, however IT / Data Center Managementteams can lead this journey
Align with technology and consulting partners that “get it” – product and serviceofferings should elicit efficient designs and practices
Stay focused and don’t try to boil the ocean – focus on optimizing servers, storage, anddesktop first in order to gain control over space, power, and cooling (stabilize the load)
If physical relocation is in your future, seek some level of outside expertise – expectation and risk management are KPIs of any migrations; most organizations don’tdo relo as part of SOPs
