HP 199633-001 Fast-Wide SCSI-2/P Controller Card

Product Description

The HP 199633-001 is a controller card that enables Fast-Wide SCSI-2 connectivity for compatible HP computer systems. SCSI (Small Computer System Interface) is a set of standards for connecting and transferring data between computers and peripheral devices. The 'Fast-Wide' designation indicates that this card supports both increased speed (Fast SCSI) and a wider data path (Wide SCSI), allowing for significantly higher data transfer rates compared to older SCSI standards. Specifically, Fast SCSI doubles the transfer rate of standard SCSI, while Wide SCSI increases the data bus width from 8 bits to 16 bits. Combined, Fast-Wide SCSI-2 offers substantial performance improvements, making it suitable for connecting high-capacity hard drives, tape drives, and other storage peripherals that require high throughput. The SCSI-2 standard itself provides a robust and reliable interface for these devices. This controller card is designed to be installed in an expansion slot within an HP server or workstation, providing the necessary ports and logic to manage communication with attached SCSI devices. It is a crucial component for systems that rely on SCSI for their primary or secondary storage, ensuring efficient and reliable data management for demanding applications.
