Product Description
The HP 273915-B21 Smart Array RAID Controller is a high-performance storage solution designed for HP ProLiant servers that utilize SCSI drives. It features the Ultra320 SCSI interface, offering a maximum theoretical throughput of 320 MB/s, which is essential for environments with high I/O demands. The controller is equipped with 128MB of cache memory, providing a buffer that significantly speeds up RAID operations, enhances read/write performance, and reduces the burden on the server's CPU by offloading complex calculations. This controller supports a comprehensive suite of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This broad compatibility allows for flexible storage array configurations, enabling administrators to balance performance needs with data redundancy requirements. Whether implementing simple mirroring for data protection or more complex striping with parity for both performance and fault tolerance, the 273915-B21 provides the necessary features. Integrated via a PCI-X bus, the controller ensures high-speed communication with the server's system board. This makes it a suitable choice for enterprise-level applications that require reliable, high-speed access to data and robust protection against drive failures. The 273915-B21 is a key component for maintaining data integrity and ensuring high availability in SCSI-based storage environments within HP ProLiant servers.
