Product Description
IBM 2748 PCI RAID Disk Unit Controller
The IBM 2748 is a high-performance PCI-X RAID Disk Unit Controller designed for older Power Systems, iSeries, and pSeries servers. It supports advanced RAID configurations (RAID 0, 1, 5, 10) with Ultra320 SCSI interface, battery-backed write cache for data protection, and connectivity for multiple internal disk drives, delivering improved performance and reliability in legacy environments.
This controller is excellent for upgrading or maintaining older IBM systems that require faster SCSI throughput and robust RAID protection with caching, supporting high-availability setups for databases, file serving, ERP systems, and business-critical applications running on AIX or IBM i.
