I have a Dell PowerEdge 2850 with a PERC 4e/Di/Si RAID controller. It currently has three 36 GB 15k SCSI drives (hot plug) configured as a RAID 5 array. There are 3 additional open hot plug hard drive slots and we would like to create an additional RAID 1 or RAID 5 array with some larger drives for a storage volume.
I've never done anything like this before and was wondering:
1. Is it possible with this controller to have a second RAID array? If so can it be RAID 5?
2. Do the drives have to by SCSI drives or can they be SATA drives? If SCSI only do they have to be 15k drives?
3. If this is possible, is it fairly straightforward to set it up in the RAID controller BIOS or is it a complex process?
