The 615418-B21 is the HP Smart Array P822/2GB FBWC 6Gb 2-ports-Int/4-ports Ext SAS controller. It combines 2GB of flash-backed write cache with two internal ports and four external ports, and it is an option for ProLiant Gen8 rack servers.
On the ProLiant DL380p Gen8 the P822 has only two internal ports, like the P420 controller, and cannot attach both 8 SFF drive cages through a single controller. When a P822 is chosen for the 12 LFF or 25 SFF model, it cannot go in slot 3.
The ProLiant DL160 Gen8 supports it too. With 8 SFF models the P822 requires two cable kits, the 676895-B21 HP Mini SAS 800mm Gen8 Cable Kit and the 662963-B21 HP Mini SAS 700mm Gen8 Cable Kit. The 662963-B21 is also needed with the Smart Array P222/512 FBWC controller and the H222 host bus adapter.
For Gen9 servers, the 726911-B21 H241 external Smart Host Bus Adapter is a separate external-port choice, and further controllers are in HPE server interface cards.
