I have a Dell PowerEdge 2650 laying around that I would like to convert into an NFS/SAN server. It is a 2U rack mountable machine with 3 x 36G Ultra 320 SCSI drives in it currently. I'd like to put as much disk space in and build a RAID 5 stoage solution. There are two drive enclosures with "blanks" covering the other 2 drive bays. My question is, what are the biggest drives I can put in this Dell? Is there limitations based on the RAID controller? Can I put 5 x 300GB Ultra 320 drives in the machine?
I'd like to try to build a low cost, but reliable iSCSI SAN if possible.
