Windows Server 2008 R2 Server Core Parking
• Overview– Scheduling virtual machines on a single server for
density as opposed to dispersion– This allows “park/sleep” cores by putting them in
deep C states
BenefitsSignificantly enhances Green IT by being able to reduce power required for CPUs

Second Level Address Translation (SLAT)New Processor Feature Support
• Overview– Uses new processor features to improve performance and
reduce load on Windows Hypervisor• AMD: Nested Page Tables (NPT)• Intel: Extended Page Tables (EPT)
BenefitsImprove memory management performanceReduce in memory copiesMemory usage will decrease from ~5% to 1% of total physical memoryMost improvement with large working sets (TS/SQL)
Jumbo Frame Support
• Overview– Enables 6x larger payload
per packet– Ethernet frames >1,500
bytes– Ad hoc standard is ~9k
BenefitsImproves throughputReduce CPU utilization of large file transfers
Live Migration• Overview– Moving a virtual machine from one server to
another without loss of service
BenefitsEnables new scenariosLoad balancing VMs for powerLoad balancing VMs for CPUUpgrade of host hardware and maintenance
Cluster Shared Volumes
• NEW Cluster Shared Volumes (CSV) in Windows Server 2008 R2
• Overview– CSV provides a single consistent file name space; All
Windows Server 2008 R2 Server servers see the same storage
BenefitsEasy setup; Uses NTFSNo reformatting SANsCreate one big data storeNo more drive letter problemsExisting tools just workHighly recommended for live migration scenarios
Hot Add/Remove Storage• Overview– Add and remove VHD and pass-through disks to a
running VM without requiring a reboot. • Hot-add/remove disk applies to VHDs and pass-through
disks attached to the virtual SCSI controller
BenefitsEnables storage growth in VMs without downtimeEnables additional datacenter backup scenariosEnables new SQL/Exchange scenarios
Processor Compatibility Mode• Overview
– Allows live migration across different CPU versions within the same processor family (i.e. Intel-to-Intel and AMD-to-AMD).• Does NOT enable cross platform from Intel to AMD or vice versa.
– Configure compatibility on a per-VM basis.– Abstracts the VM down to the lowest common denominator in
terms of instruction sets available to the VM.
