At time of posting, we were doing both ISCSI and Fiber Channel. As of now, all of the VM storage has been moved to Fiber. This has not affected the deduplication rates at all. We also do deduplication on our CIFS shares for Windows users directories. NFS would be a lot better than CIFS to store VMs if you had to chose between one of the NAS(network) protocols and not block level (ISCSI, Fiber Channel).

Which one are you using? ISCSI or CIFS for the storage in VMWARE to store the VMs ?

Nice write up.

Nothing really noticeable, but it is currently running only about 13 VMs that are non-critical. I don’t think there would be a big hit unless we were deduping full terabyte volumes. Also, the volume is spread over multiple smaller 134 15krpm spindles, so that also increases read/write performance

any performance impact on the VM’s while deduplication was running?
