Hi Greg, yep, it's a StorageWorks box. Not sure what the exact model# really is.
I'm certified to design Storage Works raid setups, so if you post details such as the array model number (HSZ80? HSG80?), # of controllers, # of shelves, # of disks per shelf I can give you more feedback.
Dual HSG80, 4 shelves, 6 disks per shelf.
The next step in higher reliability is to move to 3-disk mirror sets. ie. each of the 3 disks have exactly the same info. This is still called RAID 10, but now you will have 7 3-drive mirror sets all striped together with 3 hot spare drives. You can obviously survive a 2 drive failure.
That's one option I've somehow completely managed to avoid ... thanks for mentioning it.

Yes, it did, thank you very much Greg. Now that you're on-line anyway, here's something I've been pondering - I have a 2nd SWKS box, except this is an older model with dual HSZ70 controllers. I'm fairly certain one box will be plenty, but I can't help thinking if this 2nd box could be hooked up to the first - sort of as a BA370 extension cabinet? I'm guessing I would need to remove the controllers. /Per Jessen, Zürich
