There are two SAS controller card options for the Sun SPARC Enterprise T5120 and T5220 servers (both options support RAID). The standard option uses the on-board SAS controller card preinstalled on every server. The second option is a StorageTek SAS RAID Internal Host Bus Adapter (HBA) PCIe card. The internal cabling of your server will be different depending on the SAS controller card option you choose.

2 Route the cable through the cable retainer
3 Route the cable along the power supply midwall
4 Proper location of heat-shrink tubing
5 Route the cable through the fan midwall to the hard drive backplane
Note - For information about installing PCIe HBA cards, refer to the document, Installing the StorageTek SAS RAID HBA Into the SPARC Enterprise T5120 and T5220 Servers.
