Product Description
The HP Smart Array Ultra160 SCSI 128MB PCI RAID Controller (SKU: 158939-B21) is a powerful storage solution designed to enhance the performance and reliability of HP servers. It leverages the Ultra160 SCSI interface, which provides high-speed data transfer capabilities essential for demanding enterprise workloads. The controller is equipped with a substantial 128MB of cache memory, acting as a high-speed buffer that significantly accelerates read and write operations by storing frequently accessed data and commands, thereby reducing latency and improving overall system responsiveness. This RAID controller offers comprehensive support for multiple RAID levels, including 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). This flexibility allows IT administrators to configure storage arrays that precisely match their application requirements, whether the priority is maximum throughput, robust data protection, or a combination of both. The PCI form factor ensures compatibility with a wide range of server systems equipped with standard PCI slots. Engineered for mission-critical applications where data integrity and availability are paramount, the 158939-B21 controller incorporates advanced error detection and correction mechanisms to ensure data accuracy and prevent data loss. Its robust feature set and high performance make it an excellent choice for servers hosting databases, critical business applications, and other environments that demand reliable and consistent storage performance.
