Due to the age of the server, and it being End Of Life, we don't have most of those drives available any longer. What I could do is give you the part number of the supported SAS 500GB hard drive, then what I suggest is going through a 3rd party, or Spare Parts (800-357-3355) to get the drives.
YP777 - 500GB SAS, 7.2K, 3.5", Seagate Moose
Let me know how it goes.
