Origin 350 Drive Carriers
The Origin/Onyx 350, Prism, Altix 350, and Altix 450/4x00 all use the same drive carriers. These are standard parts used by a number of manufacturers, notably Intel's SC5200, SRSH4, SR1300/2300, and SR1400/2400 and Sun's v60x and v65x servers.
The units carry "Assy A65278-00x" on a sticker, where the "-00x" may end in any digit though "-005" seems common. This assembly number can be useful when searching for parts in the Internet. According to SR1300/SR2300 support documents at intel.com, the Intel accessory part number for the drive carrier is FXX2DRVCARBLK, UPC code "7 35858 14621 0" and "MM #" 835853. However note that there is some indication that Intel may recycle these accessory part numbers in the FXX- form between different models.
As of early 2011 these drive sleds are commonly available on eBay for US$10.
