Well, your plan on storage usage goes to 1% of those who doesn't need reliability and roomy media back-end. So, it can work out well - but unfortunately this is not a silver bullet. -- Roman -- This message posted from opensolaris.org ___ zfs-discuss

Thank you so much for the detail. The 10Gbe is attached to 10Gbe port on a Vmware ESX server. I am trying to use NFS for VMware. When I bought the SSD's I was after low seek time not necessarily total bandwidth. I can add devices over time to get the bandwidth up. I am puzzled why even my
