HP 171383-001 Smart Array Ultra3 SCSI 128MB PCI-X Raid Controller

Product Description

The HP 171383-001 is a high-performance RAID controller designed to manage SCSI storage devices within HP ProLiant server environments. Featuring an Ultra3 SCSI interface, it supports high data transfer rates crucial for demanding I/O operations. The PCI-X bus ensures ample bandwidth for the controller to communicate efficiently with the server's motherboard, preventing bottlenecks during intensive data transfers. With 128MB of onboard cache memory, it significantly accelerates read and write operations by buffering data, reducing latency and improving overall system responsiveness. This controller offers comprehensive RAID (Redundant Array of Independent Disks) capabilities, supporting various levels including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for balance), RAID 6 (striping with dual parity for enhanced redundancy), and their combinations like RAID 10, 50, and 60. This flexibility allows administrators to configure storage arrays based on specific needs for performance, data protection, or a balance of both. Hot-plug support ensures that drives can be added or removed without shutting down the server, facilitating maintenance and expansion with minimal downtime. Compatibility is typically with older generations of HP ProLiant servers that utilize PCI-X slots. The controller often supports optional Battery-Backed Write Cache (BBWC) modules, which provide power to the cache memory in the event of a sudden power loss, ensuring data integrity. The HP 171383-001 is a robust solution for businesses requiring reliable and high-performance storage management for critical data.
