ProLiant DL20 Gen9 is the server for the 820834-B21, the HPE Smart Array P440/2GB FBWC 12Gb 1-port Int SAS Controller. One internal port, a 2GB flash-backed write cache (FBWC) and a 12Gb SAS interface are in the name, and the controller is chosen from the Smart Array controller options of the DL20 Gen9.
Cabling for a P440 controller in the DL20 Gen9 depends on the chassis: the 2LFF Mini SAS P440 Cable Kit is 811279-B21 and the 4SFF Mini SAS P440 Cable Kit is 811282-B21. The P440 needs to be populated in slot 2 (Full Height), and the DL20 Gen9 option 822451-B21 is required to install the HPE Smart Storage battery, 727258-B21, on a P440 with FBWC such as 820834-B21 or 726821-B21 P440/4GB controller. The wider range of Gen9 server controllers is in HPE server interface cards.
