- 19. Cloud Admins Want Scale, Customers Perf DVMQ, IPsec Task Offload, SR-IOV IPsec Task Offload: Microsoft expects Dynamic Virtual Machine Queue deployment of Internet Protocol security (VMQ) is a feature available to (IPsec) to increase significantly in the coming years. The large demands placed on the CPU computers running Windows Server by the IPsec integrity and encryption 2008 R2 with the Hyper-V server role algorithms can reduce the performance of installed, that have VMQ-capable your network connections. IPsec Task Offload network hardware. VMQ uses is a technology built into the Windows operating system that moves this workload hardware packet filtering to deliver from the main computer's CPU to a dedicated packet data from an external virtual processor on the network adapter. machine network directly to virtual machines, which reduces the SR-IOV is a specification that allows a PCIe device to appear to be multiple separate overhead of routing packets and physical PCIe devices. The SR-IOV copying them from the management specification was created and is maintained operating system to the virtual by the PCI SIG, with the idea that a standard machine. specification will help promote interoperability. SR-IOV works by introducing the idea of physical functions (PFs) and virtual functions (VFs). Physical functions (PFs) are full- featured PCIe functions; virtual functions (VFs) are “lightweight” functions that lack configuration resources.
- 20. Advanced Network Security DHCP Guard, Router Guard, Monitor Port • DHCP Guard is a security feature that drops DHCP server messages from unauthorized virtual machines pretending to be DHCP servers. • Router Guard is a security feature that drops Router Advertisement and Redirection messages from unauthorized virtual machines pretending to be routers. • Monitor Mode duplicates all egress and ingress traffic to/from one or more switch ports (being monitored) to another switch port (performing monitoring)
- 21. Manage to a Service Level Agreement Network Bandwidth & QoS • Bandwidth Management allows you to easily reserve minimum or set maximums to provide QoS controls to manage to a service level agreement

VMware Comparison Windows Server “8” VMware VMware vSphere Capability Beta Hyper-V ESXi 5.0 5.0 Enterprise Plus Dynamic Virtual Machine Queue Yes Yes Yes IPsec Task Offload Yes No No SR-IOV Yes DirectPath I/O1 DirectPath I/O1 Storage Encryption Yes No No 1. 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. 24
