Overview
The HPE Smart Array P841/4GB FBWC 12Gb 4-Port External SAS Controller, MPN 726903-B21, is a RAID controller for connecting external SAS storage to a server. It has 4 x4 external mini-SAS HD ports, a 12Gb SAS interface and 4GB of flash-backed write cache.
The cache matters for write performance on arrays, and the flash backing protects cached writes if power is lost. The ports are external, so this card is for attaching drive enclosures and shelves rather than internal drive bays.
It installs in a PCIe 3.0 x8 slot. Verify that your server has a free slot of that type and that your enclosures accept mini-SAS HD cabling; cables are not included.
The spare part number is 750051-001.
The 726903-B21 is offered new or refurbished, and both conditions carry a choice of 1 year or 3 years of warranty. No used offer is listed. Send us your server and enclosure models, and we will reply with pricing and availability.
