Product Description
The HP 274400-001 Smart Array Ultra160 SCSI RAID Controller is a hardware-based RAID solution designed to enhance the storage capabilities of HP ProLiant servers. It utilizes the Ultra160 SCSI interface, offering a significant bandwidth of up to 160 MB/s per channel, which is crucial for high-performance storage configurations. The controller comes equipped with 64MB of cache memory, which accelerates RAID operations by storing frequently accessed data and intermediate calculations, thereby reducing the load on the host CPU and improving overall system responsiveness. This controller supports a comprehensive range of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This flexibility allows administrators to configure their storage arrays based on specific needs for performance, data redundancy, or a combination of both. For instance, RAID 1 provides mirroring for data protection, while RAID 5 offers a balance of performance and redundancy, and RAID 6 adds an extra layer of fault tolerance with double parity. Designed for integration into HP ProLiant servers, the 274400-001 typically uses a PCI bus interface. It is a reliable choice for businesses that require robust data protection and improved storage performance from their SCSI-based disk arrays. Its hardware RAID acceleration offloads complex calculations from the server's main processor, ensuring that system resources are available for applications rather than storage management.
