Server Impact

More cores in a CPU = More Processing

Critical for application that become processing bound

Core densities are increasing 2/4/6/8/12/16

CPUs are x64 based

Evolution of Server Scalability: MemoryDensity

DIMM Slots DIMM

DIMMsDual Inline Memory Module - a series of dynamic random-

access memory integrated circuits. These modules are mounted on a

printed circuit board

Rankingmemory modules with 2 or more sets of DRAM chips

connected to the same address and data buses. Each such set is

called a rank. 1 dual and quad ranks exist

SpeedMeasured in MHz most server memory is DDR3 and PC3-10600 = 1333 MHz

As Server memory increases clock speed will sometimes drop in

order to be able to utilize such large memory amounts

Growing Use of Platform Virtualization

Platform Virtualization: Physical servers host multiple Virtual Servers

Better physical server utilization (Using more of

existing resources)

Virtual Servers are managed like physical

Access to physical resources on server are

shared

Access to resources are controlled by

hypervisor on physical host

Key Technology for : VDI / VXI

Server Consolidation

Cloud Services

DR

Challenges: Pushing Complexity into virtualization

Who manages what when everything is virtual

Integrated and virtualization aware products

Server Deployment Today

Over the past 20 years An evolution of size, not thinking

More servers & switches than ever

Management applied, not integrated

Virtualization has amplified the problem

Result More points of management

More difficult to maintain policy coherence

More difficult to secure

More difficult to scale

Service Profiles

Contain server state information

User-defined

Each profile can be individually created

Profiles can be generated from a template

Applied to physical blades at run time

Without profiles, blades are just anonymous hardwarecomponents

Consistent and simplified server deploymentpay-as-you-grow deployment Configure once, purchase & deploy on an as-needed basis

Simplified server upgradesminimize risk Simply disassociate server profile from existing chassis/blade and associate to new chassis/blade

Enhanced server availabilitypurchase fewer servers for HA Use same pool of standby servers for multiple server typessimply apply appropriate profile during
