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\u003e784486-001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCache\u003c\/th\u003e\n\u003ctd\u003e4 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 ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost interface\u003c\/th\u003e\n\u003ctd\u003ePCIe 3.0 x8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eForm factor\u003c\/th\u003e\n\u003ctd\u003ePCIe full height, half length\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 P840 is a full-height, half-length board, so it needs a full-height slot that is physically x8 or wider; low-profile-only risers cannot take it. The 4 GB cache needs the HPE Smart Storage Battery, which HPE requires for Gen9 P-series controllers and sells separately. The two x8 internal ports reach the backplane through server-specific cable kits, which usually stay with the chassis. For the modular slot instead of a PCIe slot, the P840ar is the board-mounted version. Gen10 servers moved to SR Gen10 controllers.

The 4 GB cache suits RAID 6 and 60 on large spinning arrays. If the modular slot is free, the P840ar saves the PCIe slot; for eight drives, the low profile P440 is enough and fits more slot positions.\u003c\/p\u003e\u003cp\u003eEvery part we sell is tested and covered by our 180-day warranty.
