Ah, but now we also have the filesystem-storage split... I'm contemplating using a single object pool (possibly Ceph) to provide both a slice for NFS /home and slices & pools for project storage. The reasons are more economic than performance or even management. The funding model is similar to "buy nodes for a cluster, get proportional access." If I can convince people to add a little overhead, then everyone gains some replication, etc... But, really, our current network setup is the limiting factor in back-of-the-envelope performance estimates. And I'm the limiting factor in the whole thing, as our system staff is, um, stretched thin. _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
