Interface bound to process

Storage assigned to specific locations

Network assigned to specific locations

Operating System assignedto specific hardware

Without Virtualization With Virtualization

Why Virtualization?

Moore’s Law continuesCore count continues to grow

Software parallelism

One workload per server todayConsolidation and partitioning drive up utilization and parallelismThe scale-up server of today is the scale-out server of the futureVirtualization is a scale-up workload

4

Why Virtualization?

Huge growth in memory4GB to 2TB

Server industry aggressively moving to 64-bitConsolidation density memory limited

Homogeneous consolidation can be more efficient

Memory controllers moving on chipMulti-socket system will be NUMA machinesMemory per socket increasing

Flash memory

5

Why Virtualization?

ProgressionSoftware only virtualizationCPU virtualization (Intel VT and AMD-V)MMU virtualization (EPT / NPT)DMA virtualization (IOMMU / DMAr)Interrupt and timing virtualizationIO virtualization

Hardware assists will simplify virtualization layer and improve performance and scalability
