Proliant DL380 G8 Rail KitFF

The HPE 720863-B21-RFB is a refurbished 2U Small Form Factor ball-bearing rail kit for mounting a supported server in a rack. The listing describes it for G8–G10 servers and associates this exact MPN with the ProLiant DL380e Gen8, DL380p Gen8 and DL385p Gen8.

Its 2U format and SFF designation identify the rack and server form factor, while the ball-bearing rail design supports sliding movement during access to the mounted server.
