64 Logical Processor Support

OverviewProvides Hyper-V the ability to utilizes up to 64 of the logical processor pool presented to Windows Server 2008 R2

BenefitsSignificantly increases host server densityEasily provide multiple processers per virtual machine

VM Chimney (TCP Offload Support)

OverviewTCP/IP traffic in a VM can be offloaded to a physical NIC on the host computer. (disabled by default)

BenefitsReduce CPU burdenNetworking offload to improve performanceLive Migration is fully supported with Full TCP Offload

Cautions: Not all applications benefit from Chimney

Works best for long-lived connections with large data transfers Applications with pre-posted buffers

Chimney capable hardware supports a fixed number of offloaded connections – shared between all VMs

Processor Compatibility ModeOverview

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.

BenefitsProvides a great deal of migration flexibility within clusters.Enables migration across a broader range of Hyper-V host hardware.No specific hardware requirements needed.
