Servers Market and Drivers

Market

The x server market represents approximately , ,servers per year, and will remain the center of innovation andinvestment.

The market is split / / in terms of the tower/rack/blade formfactors, with blades and extreme scale-out as the fastest-growingsegments.

Key Drivers

Acquisition cost will always be important

Energy consumption has become a priority, but focus will shift tolarger aggregates as marginal gains on servers get smaller

Total infrastructure cost, including management, becomes a focusat a system/DC level

This is the jumping off point for debates about unified fabrics, sharedand virtualized I/O, new virtualization management models, etc.


11/36

Server Performance

Server performance willcontinue to increase

By , a socket serverwill have approximately -

times the performance ofthe same server in

Continued improvementsin architecture along withdensity

Niche architectures will havefreedom to embed othersystems elements on chip comm, crypto, etc.

Processors trends

Silicon compaction continues ( nm, nm, 2nm) Higher levels of functional blocks integration Large gate count

Caches, Memory controller(s), I/O, TPM

All server processors going to NUMA using processor links (no more FSB)

More efficient coherency protocols (Intel: Home Snooping; AMD: HT Assist)

Higher number of and faster interfaces Large pin-count pkg

One or more processor links More flexible designs Intel QPI

AMD HT

Multiple memory links Flexible memory configurations

Integrated I/O links (PCIe , USB ) I/O closer to processor & memory

Core count increase continues ( , , 8, 10, 12, 16)

Core clock frequencies increase slow down (topping around GHz)

More physical memory address bits (Intel: 6; AMD: 8)

Wide range of power (TDP) bins (Intel: 7150W; AMD: 5140W)

Depends on core count, cache size, coherent link count


13/36

13 8 June, 2009

Memory trends Increase DDR3 speeds with tradeoffs on # DIMMs per channel (DPC)

DRAM chip capacity increase

DIMM capacity increase

8GB DIMM will be linearly priced in 2010

Reduced DIMM power rail and consumption

DIMM interfaces (DDR, SMI/VMSE) changing to address DDR bus limitations

Non-volatile components will add memory/storage hierarchy


14/36

Server Futures

Continued escalation of core count and memory

Expect differentiation in choice of on-board peripherals andaccelerators at both chip and board level

Continual pressure toward denser, higher layer count boards

Communications radius effects, SI and connector limits

Changing options for design

Link-based connections for more flexible design

More options for local and near storage

Design differentiation as requirements bi/trifurcate

GP, scale out, virtualization designs

Value increasingly in packaging, rack-scale and largerintegration


15/36

Changing Focus for Server Design Server design is increasingly merging with DC

design for rack-level and larger aggregates

As designs become more aggregate, theoptimizations become more complex

Server design has beenfocused on the chip to chassisdomain

Increased demand for scale-out isshifting the focus to rack, moduleand entire DC scale designs

Storage Density

Storage density will followa pattern similar to serverperformance

By 2010 -11, usable

densities will exceed 1PB/rack

Block storage device trends Cost competiveness drove HDD industry consolidation

HDD interfaces going fast serial links: SAS/SATA SAS growing to be the interface of choice in enterprise

FC HDD growth is flat or shrinking

Switched SAS also enables storage fabric for shared block storage

But, lots of things need to be developed for complete solutions

HDD capacity continue to increase, while rpm tops at 15K HDD areal density ~30-40% AGR [SFF 0.5TB in 10, TB in 11]

SFF dominates in enterprise

Enterprise SFF 10K adoption growing (largest segment) while LFF 15K vol.shrinking

Flash storage is disruptive

SSD /GB cross-over with SFF SAS 15K rpm in 11-12

256G/512G in 10, TB in 11

PCIe-based Flash storage significantly improves storage I/O

New storage hierarchies and models, including memory cache, disc cache, i/oaccelerators

Virtualization A Blessing & a Curse

Virtualization of servers, storage, networks and I/Ohardware brings major benefits

Capital resource efficiency (the initial sell)

Standardization and ease of migration

A gateway to adaptive architectures

as well as significant burdens management,management, management

Are you substituting one vendor lock-in for another?

How many more tools do you want to add to your environment? How do you integrate the physical and virtual management layer?

Be prepared for major innovation and vendor conflict inthis arena for the next five years

You need to have a strategy, metrics and a roadmap


23/36

Enterprise Customers continue to bechallenged managing infrastructure

Server admin and management costs grow with theinstalled base of servers1

Basic operations such as installing a server typically take weeksrequiring manual coordination across multiple customerorganizations

Power, cooling and facilities limitations continue to loomas limits - the 10 Million server

This will drive multiple deployment options such as cloud in anattempt to tap economies of scale

Virtualization helps some things, but potentiallycomplicates the management environment

Expect continued experimentation in virtualization managementmodels, expanded virtualization options

29/36

Some Essential Principles

Draconian standardization

Its really amazing how simple you can make an enterpriseenvironment if you just dont let anyone complain (or at least stoplistening to them)

Vendor simplification Software is particularly important

You may want to maintain very coarse-grained hardwareheterogeneity for vendor management

Almost always, fewer is better

Locations, software titles, options

Once standardization has been in place for a full dev cycle,requests for variations become few and far between

Data Center & ITTransformationWhat Can You Achieve?


32/36

Best Practices to Achieve the Vision

Simplify through standardization: Standard & consistent data centerarchitecture and design; standard hardware, tools, and infrastructure

Establish PMO for governance: Provides framework for how effort willbe structured, who will make decisions

Gomodular:Allows for fast build, flexibility, scalability, and

efficiencies; isolates and separates risk

Break plan into bite-size chunks: Divide into workstreams, engageproper expertise, identify clear goals & deliverables by quarter

Synchronizetiming is everything: Facilities must be ready toreceive servers; servers must be ready to receive applications

Define one set of processes:A properly documented single set ofprocesses aligned to ITIL V3 model ensures desired outcomes,allows for automation

Actively manage and communicate change: Change managementand well-executed communication strategy critical for success

What Lies Beyond: Cloud Computing

A pool of abstracted, highly scalable, and managed compute infrastructure

capable of hosting end customer applications and billed by consumption.

If managing a massive data center isnt a core competency of your business, maybe you

should get out of this business and pass the responsibility to someone who has

Amazon CTO Werner Vogels, 2007 Next Generation Data Center Conference

Cloud computing's ecosystem in the future willinclude Google-like public clouds as a platformfor applications, and virtual private clouds, whichare third-party clouds, or segments of the public

cloud with additional features for security,compliance, etc.

The data centre of the future also will includeprivate (internal) clouds, which will be anextension of virtualization and used primarilybecause of their capital or operationalefficiencies. For some applications, data justwon't leave the enterprise.


34/36

Clouds A Long Haul

Good concept, great marketing buzz.

Hey, where are the applications?

Welcome to the world of almost consistent data.

Where did you say my data is?

Did someone say standards?

Hi, Im Coke. Am I sharing my cloud with Pepsi?

Whats the difference between a well designedshared services platform and an internal cloud?

But it does have a future
