IBM 2741 PCI RAID Disk Unit Controller

The IBM 2741 is a PCI-based RAID Disk Unit Controller designed for older Power Systems, iSeries, and pSeries servers. It enables RAID-protected storage configurations (RAID 0, 1, 5) with support for multiple internal SCSI disk drives, battery-backed cache for data protection during power loss, and improved performance for legacy environments.

This controller is well-suited for upgrading or maintaining older IBM systems that require RAID functionality with write caching, supporting high-availability setups for databases, file serving, and business-critical applications running on AIX or IBM i.
