Product Description
IBM 5590 2780 Ctlr w/574F Aux Write Cache
The IBM 5590 (feature code for 2780 with auxiliary write cache option) is a high-performance PCI-X RAID Disk Unit Controller equipped with additional auxiliary write cache for superior data protection and write performance. It supports RAID 0, 1, 5, and 10 configurations using Ultra320 SCSI interface, making it ideal for demanding legacy Power Systems and iSeries environments requiring robust storage reliability and speed.
This controller excels in providing data redundancy, enhanced I/O throughput, and reliable storage expansion for databases, ERP systems, file serving, and business-critical applications running on AIX or IBM i. Ideal for upgrading older systems or replacing failed RAID adapters while maintaining high availability and performance.
