[Lustre-discuss] Future of LusterFS?

[Frank Leers]

Your mention of hosting VM's below: "to store VM-images which are used by KVM" is interesting.  You'd probably
benefit from some sort of de-duplication, which lustre doesn't do.  The workload would also seem to not fit into 
lustre's key strengths.  

Have you considered using something like a ZFS backend, sharing out either iSCSI LUN's or NFS
to your 20 clients?  On the surface, this looks like it would be a better fit.  Have a look at the Oracle 7000 appliances
if you want something turnkey, or look into one of the many ZFS appliances built on OpenSolaris...or build your own.

Surely, you've heard of kickstart (or some other provisioning mechanism).
