2TB is the largest disk any of the "RAID" controllers for this server will support. In non-RAID mode, I have heard the SAS 6/iR will support larger disks. Stay away from desktop/laptop/NAS drives and stick to enterprise-class drives if you are using a PERC.
This server was donated to us (small non-profit). I have it up and working, but we need to order some new HDD's for it. I have downloaded all of the manuals and any other info I could find. It seems like I saw that there was a max size of 1 TB but I can't find that again. Can you point me in the right direction? Thanks, Alan
