PERC cable for the R640 10 Bay. It connects to the backplane and then terminates at one of Dells Mini Mono RAID controllers.
Here it is installed in the server. It routes along the right side of the chassis and has just enough length to reach the mini mono controller (mini mono RAID not pictured):
This cable connects the backplane to a PCIe Raid controller on the R740 8 Bay LFF chassis.
This is the battery for many HP Smart Array controllers. It is widely compatible in both G9 and G10 servers. Close to the backplane you’ll notice a small notch. This notch accepts the tab seen on the battery. It is then further held in usually by a blue clip. The wire connects straight to the motherboard. Functionally, this battery maintains the RAID cache in the event of power loss.
This cable attaches from the backplane to a compatible smart array controller in the HP DL 380 G9 server. It is specific to the 8 bay chassis.
This is the RAID cable for the DL 325 G10 8 Bay chassis. It attaches to the backplane and then terminates at a RAID controller installed in the Mezzanine slot.
