Q. Does VMware support the Windows Server 2008 /Server 2008 R2 NFS implementation?

A. In Server 2008 and Server 2008 R2, the in-box NFS implementation meets NFS version 2 and version 3 standards, which would support connections from VMware. However, VMware doesn’t officially support Microsoft as a NFS platform (not surprisingly).

If you want to use VMware with a Microsoft NFS implementation, you need to make a minor change. By default, the Microsoft NFS implementations supports16 connections per IP address. Each virtual machine (VM) on VMware requires two connections, so you’d only be able to run eight VMs on each VMware server. You should, therefore, change the number of connections per IP address to 8192 to ensure the number of NFS connections doesn’t limit the number of VMs per VMware host. See tomorrow's FAQ for instructions on changing the number of supported connections.
