Product Description
The DEC HSZ70-AA is a dedicated hardware RAID controller developed by Digital Equipment Corporation (DEC) for use within their server product lines. Its primary function is to manage multiple SCSI hard drives and present them to the operating system as logical volumes, while providing advanced data protection and performance enhancement features through hardware RAID configurations. By offloading RAID calculations from the host CPU to its own dedicated processor, the HSZ70-AA ensures high performance for RAID operations. It typically supports various RAID levels, such as RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for balance), and potentially higher levels like RAID 6 or RAID 10, depending on the specific model and firmware version. This allows administrators to configure storage arrays that meet specific requirements for speed, data integrity, or a combination of both. Integration into DEC systems would involve connecting the controller to the server's backplane or bus and then connecting the physical SCSI drives to the controller's ports. The HSZ70-AA is crucial for environments where data availability and performance are critical, such as in enterprise servers hosting databases, file shares, or other mission-critical applications. Its hardware-based approach provides a more reliable and performant RAID solution compared to software-based RAID implementations.
