Product Description
IBM 5580 2780 Ctlr w/Aux Write Cache 5708
The IBM 5580 (feature code for 2780 with auxiliary write cache 5708) 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.
IBM 5580 includes a #2780 PCI-X Ultra4 RAID Disk Controller and a secondary IOA with 757MB of auxiliary maximum compressed write cache. The #2780 and the secondary IOA each require one PCI-X slot and must be installed together in the same CEC or I/O unit/drawer/tower. The #2780 and the auxiliary write cache IOA are connected by a SCSI cable (provided). Feature #2780 will not appear on IBM ordering, shipping, or inventory documentation. The connecting SCSI cable is attached to port four of the #2780, reducing the number of SCSI buses that support disk drives from four to three. The reduction of SCSI buses may also reduce the number of disk drives supported by the #2780, depending on the CEC or I/O unit/ drawer/tower in which the #2780 is installed. No disk drives are driven by the auxiliary write cache IOA.
