HP 804367-B21 Smart Array SATA/600 6Gb/s SAS 1GB PCIe Raid Controller

Product Description

The HP 804367-B21 is a high-performance Smart Array RAID controller designed to enhance storage capabilities within HP ProLiant server environments. It supports both SATA (Serial ATA) and SAS (Serial Attached SCSI) drives, offering broad compatibility with various storage media. The controller operates at a data transfer rate of 6Gb/s per lane, ensuring efficient communication with connected drives. Featuring 1GB of cache memory, this controller significantly accelerates RAID operations by storing frequently accessed data and intermediate results. This dedicated cache, often paired with a battery backup unit (BBU) or flash-backed write cache (FBWC) for data protection during power outages, helps to improve read and write performance, especially in demanding I/O workloads. The controller supports a range of RAID levels, including 0, 1, 10, 5, and 50, providing flexibility for data redundancy and performance optimization. As a PCIe (Peripheral Component Interconnect Express) card, the 804367-B21 integrates into standard PCIe slots found in most servers. Its robust feature set makes it suitable for mission-critical applications that require reliable data storage, high availability, and accelerated performance. This controller is a key component for building scalable and resilient storage solutions in enterprise data centers.
