Product Description
The HP 787840-B21 is a high-performance Smart Array P440ar SAS controller designed to deliver advanced storage capabilities for HP ProLiant Gen9 servers. This controller utilizes a PCIe 3.0 x8 interface, providing ample bandwidth for demanding storage operations. It features two internal Mini-SAS HD (SFF-8643) connectors, allowing for the connection of multiple SAS and SATA drives, including SSDs and HDDs. The P440ar controller supports a comprehensive range of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This flexibility enables administrators to configure storage arrays that balance performance, redundancy, and capacity according to specific workload requirements. The inclusion of 2GB of Flash-Backed Write Cache (FBWC) significantly improves write performance by buffering data writes and protecting them against power loss. With its robust feature set, including support for data encryption and SSDs, the HP Smart Array P440ar controller is an essential component for ensuring data integrity, optimizing storage performance, and providing reliable access to data in enterprise environments. It is commonly found in HP ProLiant DL360 Gen9 and DL380 Gen9 servers, among others, serving as a critical element of the server's storage subsystem.
