The Crisis

       Every organization is under pressure to accomplish more
        with less resources (financial, technologically, and
        human 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

       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

       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

Effective Data Management is Critical to Longevity
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

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 data
                  to 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

Legacy Cooling Designs are not Sustainable
        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
         the source

When to Relocate, and Where to Go
        While infrastructure optimization will maximize the useful life of the facility, you may still run
         out of acceptable headroom

        Every facility has a maximum capacity potential

               Physics, Public Utility Availability, Geographical Threats, Lack of Concurrent
                Maintainability

               Maybe it’s just time to consolidate!

        Relocation Options

               Internal facility

                         Are you in the business of running data centers?

               Retail Colocation Provider

                         Can they handle your specific power density today – 12/24/beyond?

               Townhouse

                         All the benefits of ownership with shared management and operations

               Tenant Improvement Build out

                         Reduced acquisition time, amortized build out costs, custom spec

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 into
         tiers (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)

Data Center Relocation: Choosing a Partner

                                                 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

                                                      Try to avoid relying on the transit company for additional
                                                       insurance - costly

Embracing the Journey

     Today’s economic times will challenge all of us to seek out more efficient ways of
      designing, building, and supporting data center infrastructure



     Stay focused and don’t try to boil the ocean – focus on optimizing servers, storage, and
      desktop first in order to gain control over space, power, and cooling (stabilize the load)


     Maintaining and sustaining the newfound efficiencies can only result from collaborative
      thought and action across the organization, however IT / Data Center Management
      teams can lead this journey


     Align with technology and consulting partners that “get it” – product and service
      offerings should elicit efficient designs and practices


     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’t
      do relo as part of SOPs
