First Hardware RAID build - advice please?
on Feb 11, 2011 at 9:51:01 pm

I'm planning to update my RAID from the current 4-disc software 0 in my MacPro to a RAID 5 with dedicated controller (for now) and here's what I'm planning (tentatively)

• RAID 5 consisting of 8 discs, 4 inside 5.1 MacPro with MaxUpgrade's kit in use for SAS connectivity , and 4 more discs in a 1U rackmount SAS chassis, possibly OWC's new 'trayless' unit, or another similar chassis.
• Areca RAID controller ARC-1880ix-12 is what I'm leaning towards at this time.

I don't have the cash or demand really for a huge system in an expansion chassis and 16-24 drives, but my the main thing I want to know, (since I've never had this many discs to play around with before) is when I create an 8 disc RAID 5 Array for storage, can I also connect another external chassis to the controller as a JBOD unit and have those drives therein function independently, with swap capability of single volumes? This would be very handy for individual cleint-drive backups and would free up my eSATA interface for file ingest and more flexibility.

I do know I would have to get an adapter to run more than one external SAS connection cause the Card only has one External SAS port as is.
