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 one set of NVME cables for the R740xd 24 bay server. It plugs into ports A0 and B0 on the backplane and terminates at an NVME controller located in the x16 slot on riser 1. The cable provides the last 4 bays with NVME support. It has just enough length to reach the first riser. If you want to enable more NVME ports that will require 2 other sets of cables, both of which are varying lengths and are their own part numbers.
Compatible with the R740xd 24 Bay chassis.

The 16 and 24 bay models of the HP DL 380 G10 require a SAS expander. This is the expander I’ve frequently come across in the field. See the following tutorial for cabling instructions.

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.
