The P840 family is HPE's 16-lane Smart Array for Gen9 ProLiant servers, running 12 Gb\/s SAS through two x8 internal ports with flash-backed write cache. It drives a 16-drive cage from one controller.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003e843201-001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCache\u003c\/th\u003e\n\u003ctd\u003e2 GB FBWC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCache protection\u003c\/th\u003e\n\u003ctd\u003eHPE Smart Storage Battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInterface\u003c\/th\u003e\n\u003ctd\u003e12 Gb\/s SAS, 6 Gb\/s SATA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInternal ports\u003c\/th\u003e\n\u003ctd\u003e16 lanes, 2x x8 mini-SAS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost interface\u003c\/th\u003e\n\u003ctd\u003ePCIe 3.0 x8 via system board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eForm factor\u003c\/th\u003e\n\u003ctd\u003ear modular (Flexible Smart Array)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRAID levels\u003c\/th\u003e\n\u003ctd\u003e0, 1, 5, 6, 10, 50, 60, 1 ADM, 10 ADM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eRefurbished\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e180-day\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe ar card mounts on the system board's modular connector and leaves the PCIe slots free; it will not fit a PCIe slot, which is what the P840 is for. Its two x8 internal ports need the server-specific P840ar cable kit for the drive cage; cables usually stay with the chassis, so confirm the kit matches your backplane. The 2 GB cache needs the HPE Smart Storage Battery. Gen10 servers moved to type-a controllers and do not take ar cards.

The tradeoff is cache: 2 GB against 4 GB on the PCIe P840, so heavy parity write loads favor the P840. For an 8-drive cage, the P440ar is enough and costs less.\u003c\/p\u003e\u003cp\u003eEvery part we sell is tested and covered by our 180-day warranty.
