Product Description
The HP 405528-B21 is a Smart Array SAS RAID controller designed to provide advanced storage management capabilities for HP ProLiant servers. This card connects via a PCIe x8 slot, offering high bandwidth to communicate efficiently with the server's motherboard and connected storage devices. Its primary function is to manage multiple SAS (Serial Attached SCSI) hard drives, allowing them to be configured into various RAID (Redundant Array of Independent Disks) levels. Equipped with 128MB of onboard cache memory, this controller accelerates storage performance by buffering frequently accessed data and commands. This cache significantly improves read and write speeds, especially in RAID configurations that stripe data across multiple drives. The controller supports common RAID levels such as RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for balanced performance and redundancy), and RAID 10 (striped mirrors for high performance and redundancy), providing flexibility to meet different application needs. By implementing RAID, the 405528-B21 enhances data protection against drive failures and improves overall storage system performance. It is a crucial component for ensuring data availability and integrity in enterprise environments. This controller is typically integrated into HP server backplanes, enabling hot-plug capabilities for SAS drives, which allows drives to be replaced or added without shutting down the server, thereby maximizing uptime.
