To frame the discussion, we use VMware ESX (vSphere) quite a bit with NFS datastores. Often times with NetApp, but lately, more often with Solaris 10 + ZFS + SSD's for ZIL (intent log or write cache).
The ZIL lets us use synchronous writes (safer) without the normal delay. Were we to try and get the same level of performance with Linux, we'd need to use async mode for our NFS shares -- and we'd lose some reliability.
However, given the latest rumblings and ruminations about Oracle potentially no longer selling entitlements for Solaris 10 on non-Sun hardware -- and then turning around and no longer allowing you to run Solaris 10 "freely", we're left with either OpenSolaris or looking at Linux again (we run Solaris 10 on Silicon Mechanics hardware).
Is there some problem with OpenSolaris or NexentaStor?
