What is the best DP configuration for an HUS110? I have 3 trays with 24 disks of 600GB SAS 10k drives (I'm showing 37TB total). I am looking to do Raid5 and there are several different disks combinations. I would also like to have some hot spares. What are the pros and cons of one or another? I know that the bigger the DP the longer the rebuilds takes. Thanks.
