XenServer vSphere | vSphere Hypervisor Windows Server Hyper-V Hyper-V Server What is Hyper-V Server?

Virtual Desktop Infrastructure Windows Client VDI licensing is per end- point device VDI technologies are typically multi- hypervisor aware Windows 7 and Windows 8 run best on Hyper-V Alternative Operating Systems Microsoft currently supports the following Linux distributions on Hyper-V: SLES: (10 SP4 – 11 SP1/2) RHEL: | CentOS: | Enhancing Linux integration and support rapidly Windows Server Licensing Reassign, where applicable, existing VL onto Hyper-V Servers However, you would lose benefits of other Windows Server 2012 capabilities

Capability Hyper-V (2012) XenServer (6.0) vSphere Hypervisor vSphere (5.0 Ent+) Dynamic Virtual Machine Queue YesVMq 1 NetQueue 1 IPsec Task Offload YesNo SR-IOV YesYes 2 DirectPath I/O 3 Storage Encryption YesNo 1.Dynamic Virtual Machine Queue (DVMQ) is not supported by either XenServer or vSphere, which both support regular VMq (known as NetQueue on vSphere). 2.Whilst XenServer 6.0 provides SR-IOV support, the release notes state: “If your VM has an SR-IOV VF, functions that require VM mobility are not possible. For example, Live Migration, Workload Balancing, Rolling Pool Upgrade, High Availability and Disaster Recovery, cannot be used. This is because the VM is directly tied to the physical SR-IOV enabled NIC VF. In addition, VM network traffic sent via an SR-IOV VF bypasses the vSwitch, so it is not possible to create Access Control Lists (ACL) or view Quality of Service (Qos).” ( 3.DirectPath IO, whilst not identical to SR-IOV, aims to provide virtual machines with more direct access to hardware devices, with network cards being a good example. Whilst on the surface, this will boost VM networking performance, and reduce the burden on host CPU cycles, in reality, there are a number of caveats in using DirectPath I/O: Very small Hardware Compatibility List No Memory Overcommit No vMotion (unless running certain configurations of Cisco UCS) No Fault Tolerance No Network I/O Control No VM Snapshots (unless running certain configurations of Cisco UCS) No Suspend/Resume (unless running certain configurations of Cisco UCS) No VMsafe/Endpoint Security support No such restrictions are imposed when using SR-IOV, ensuring customers can combine the highest levels of performance with the flexibility they need for an agile infrastructure.
