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
