Hi,

distribute the Disks even over all 6 Shelfs from Left to right.

So here: 8x 10k, than 4x 15k

4x 600GB + 8x 1.2TB

6x 600GB + 6x 1.2TB

6x 600GB + 6x 1.2TB

6x 600GB + 6x 1.2TB

Re: Ordering Hard Disk

Your disk ordering needs to be done on what I/O are you expecting from this 3PAR?

What kind of performance do you require?

Based on this will determine what drives and how many of each you need to have to meet those I/O requirements.
