Does anyone happen to have a good database/list of Data Domain part numbers?  They're not explicitly labeled on the parts themselves from what I can tell, and if replacements need to be ordered, I don't know where to start.  If a hard drive fails on a no-longer-supported system, we would be in trouble.  I know on the clariion platform at least there was a big PDF of hard drive part number conventions, such as CX-4G15-600, etc. which corresponded to the 9-digit EMC part number that was physically on the disk.  It also showed which FLARE versions were required to support which disks, but for DD I have found no such thing so far.  Please help if you can!  Thanks.
