A group of interested parties from a cross section of industry vendors has started a discussion around the merits of supporting Exchange Server on VMDK’s on top of NFS. Technically there is no reason why it should not be supported. It works great and Exchange and Windows don’t even know they’re virtual. They just talk SCSI to their virtual disks. Supportability might be a concern so having some sort of a certification or QA program is important. But provided robust, performant and reliable storage systems are used and Exchange continues to use block SCSI protocol to a VMDK why does it matter that the underlying protocol to the physical storage is NFS? I believe this provides choice to customers, and in fact many customers have been choosing this for a long time and running Exchange like this in production. They’ve continued to get support under their premier agreements. But I believe this should be extended to all customers for any qualified storage platforms. If you agree and you want to see choice of protocol provided the abstraction is solid and proven then support the movement. Vote Exchange on VMDK on NFS!
