Now that it's time to buy a new computer, Dell has changed their RAID models from the Perc6 to Perc H200 and such. Does anyone know what's inside these? I would hope they've stuck with the Megaraid controller...
Also, I can't find any info on Dell's site about how these devices can be configured. I was thinking of ten disks, as
OS: RAID1
WAL: RAID1
Database: RAID10 using 6 disks
But it's not clear to me if these RAID controllers can handle multible arrays, or if you need a separate controller for each array. We're a small shop and I only get to do this every year or so, and everything changes in between purchases!
Thanks,
Craig
