Product Description
IBM 5591 2757 Controller w/574F Aux Write Cache
The IBM 5591 (feature code for 2757 with 574F auxiliary write cache) 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.

Warranty
60-day warranty included.
Provides a disk controller with auxiliary write cache to improve cache data redundancy. The #5591 includes a #2757 PCI-X RAID Disk Controller with a 757MB write cache and a secondary IOA with 1.5GB of auxiliary maximum compressed write cache. The #2757 and the secondary IOA each require one PCI-X slot and must be installed together in the same system unit or I/O unit/drawer/tower. The #2757 and the auxiliary write cache IOA are connected by a SCSI cable.
