We are using different virtual Servers on ESXi 5 with good experience. Now we plan to move the Fileserver to a virtual machine.
VMServer ESXi 5, Windows Server 2008 R2 on HP DL380 with attached HP P2000 with SAS HBAs. The fileserver(s) with DFS is providing 12TB ‘fast’ spindles, and 36TB for archives.
Shall we use for the fileserver datadisks (not OSdisk) virtual disks or raw-devices with rdm? Or some other configuration?
