array

Hi all,

I'm planning some expansion on an HP MSA1000 SAN. My boss says that we need to have two separate arrays on the new enclosure, one for Bays 1-7, the other for Bays 8-14. Is there any reason that we need to do this?

My plan was to have the entire expansion shelf be 1 array, then create RAID 6 logical drives from that. I don't understand what splitting drives into separate arrays gain us. We don't have dual controllers, so there's no benefit there.

Thanks, CC
