I'm planning on setting up an NFS server for our ESXi hosts and plan on using a virtualized Solaris or Nexenta host to serve ZFS over NFS.
The storage I have available is provided by Equallogic boxes over 10Gbe iSCSI. I am trying to figure out the best way to provide both performance and resiliency given the Equallogic provides the redundancy. Since I am hoping to provide a 2TB datastore I am thinking of carving out either 3 1TB luns or 6 500GB luns that will be RDM'd to the storage VM and within the storage server setting up either 1 raidz vdev with the 1TB luns (less RDMs) or 2 raidz vdevs with the 500GB luns (more fine grained expandability, work in 1TB increments). Given the 2GB of write-back cache on the Equallogic I think the integrated ZIL would work fine (needs benchmarking though). The vmdk files themselves won't be backed up (more data then I can store), just the essential data contained within, so I would think resiliency would be important here. My questions are these. Does this setup make sense? Would I be better off forgoing resiliency for simplicity, putting all my faith into the Equallogic to handle data resiliency? Will this setup perform? Anybody with experience in this type of setup? -Ross _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
