RE: Disk Config With CX6000

I'm not sure about the Metalun term, but I believe some operating systems (e.g. HPUX) have internal restrictions on the I/O throughput per LUN, so you might just want to double check to see if your OS (or any other component in the I/O stack) implements this type of limitation, in which case it would be a good idea to present multiple, smaller LUNs to the OS rather than one big LUN. The best way to know for sure is to test - use dd or something similar to see what is the max IOPS you can get on a single LUN vs. two LUNs on the same disk array.
