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


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



Expand the use of virtualization throughout the enterprise – dev /test / Production & DESKTOP!

Storage Tiering and De-Duplication – part process and part

technology

Rationalize space, power, and cooling requirements to find out

how much less you could be using

Be prepared to accept the fact that relocation may be the bestoption

Prioritizing your Areas of Focus

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

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

Servers are no longer always

physical assets, they becomeinstances that exist at a

particular location and time

Originally, this portability

enabled workload management

within a data center



VM Portability Enables Disaster Recovery


Implementation Considerations

High density servers

Power and cooling needs to be assessed to

ensure adequate capabilities

Data center needs to support high density

servers

Increased risk with fewer physical servers

– Isolate business critical virtual servers from

each other on a physical level

– Make use of VMware HA

– Disaster recovery is key to business

continuity

Result

Fewer physical servers

Improve ROI

Better consolidation ratios

Reduce Risk

Selective VM placing

Implement disaster recovery

…CloudComputing



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


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

Combining De-duplication with Backups


Example Backup Integration

Combine De-duplication with VCB Backups

De-duplication Use Case

Servers with the same type of data

Servers with low data change rate

VMware Consolidated Backup Use Case

Servers with high data change rate

Result

Reduction in Storage performance overhead

Reduction in ESX platform overhead

Reduction in Network overhead



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




Paying for Power You Use and Waste

973W to support a typical 300W server

2.6W of power to drive 1W of computing power

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%

4KW is a boundary – beyond this, the old methods cease to be effective



Legacy Cooling Designs are not Sustainable

sustainability Widespread adoption of higher density equipment will

stress power distribution and cooling systems as little as 3-

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!

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

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

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
