Hi Doug, Actually, our config is:
3 RAID-5 volume groups on the array (with 2 LUNs each). 1 RAID-Z zpool per physical host composed of one LUN from each of the 3 volume groups. This allows for loss of 3 drives in a worst case, and 4 drives in a best case. -J On 12/6/06, Douglas Denny <[EMAIL PROTECTED]> wrote:

I think you are doing all raid through ZFS. The disk array is being used a FC JBOD. Thanks! -Doug
