HP 508226-B21 Smart Array 3Gb/s SAS 512MB PCIe x8 Raid Controller

Product Description

The HP 508226-B21 Smart Array controller is a high-performance RAID solution designed to provide advanced data protection and storage management capabilities for HP ProLiant servers. It connects to the server's motherboard via a PCIe x8 interface, ensuring ample bandwidth for high-speed data transfers. The controller supports the SAS 3Gb/s interface, allowing it to connect to a wide array of SAS and SATA hard drives and SSDs, offering flexibility in storage configuration. Equipped with 512MB of cache memory, this controller significantly enhances RAID performance by buffering write operations. This cache is often protected by a battery-backed write cache (BBWC) or flash-backed write cache (FBWC) module (sold separately or integrated depending on the specific server model), which ensures that data in the cache is not lost in the event of a power failure, thereby maintaining data integrity. The controller supports a comprehensive range of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60, providing options for performance, redundancy, or a combination of both, tailored to specific application needs. This Smart Array controller is ideal for enterprise environments that require high availability, data redundancy, and optimized storage performance. It can manage a large number of drives, often through the use of SAS expanders, making it suitable for scalable storage solutions. Its advanced features, such as online RAID level migration, online capacity expansion, and RAID level conversion, allow administrators to modify storage configurations without downtime, further enhancing the utility and flexibility of the server's storage subsystem.
