Product Description
IBM 5582 5738 Ctlr w/Aux Write Cache
- SCSI RAID controller
- 1.5GB Cache
IBM 5582 includes a #5738 PCI-X RAID disk controller and an auxiliary write cache IOA with a maximum compressed write cache of 1.5GB. #5738 and the auxiliary IOA each require one PCI-X slot and must be installed together in the same system unit or I/O unit/drawer/tower. #5738 and the auxiliary write cache IOA are connected by a SCSI cable (provided). Feature #5738 will not appear on IBM ordering, shipping, or inventory documentation. The connecting SCSI cable is attached to port four of the #5738, 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 #5738, depending on the system unit or I/O unit/drawer/tower in which the #5738 is installed. No disk drives are driven by the auxiliary write cache IOA. #5582 and #5583 are physically the same adapter cards but have different feature numbers that denote to IBM configurator tools whether or not an IOP is required. #5582 indicates an IOP is used.
