IBM i Power 6, 8204 (#5583) 5777 Controller w/Aux Write Cache</p><p>(Refurbished Condition Only as of August 28, 2009)</p><p>Provides a disk controller with auxiliary write cache to improve cache data redundancy. The #5583 includes a #5777 PCI-X disk controller and a secondary IOA with 1.5GB of auxiliary maximum compressed write cache. #5777 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 #5777 and the auxiliary write cache IOA are connected by a SCSI cable (provided). Feature #5777 will not appear on IBM ordering, shipping, or inventory documentation.</p><p>The connecting SCSI cable is attached to port four of the #5777, 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 #5777, depending on the system unit or I/O unit/drawer/tower in which the #5777 is installed. No disk drives are driven by the auxiliary write cache IOA. #5583 does not require an IOP.</p><p>Attributes provided: Disk Controller with auxiliary write cache</p><p>Attributes required: Two PCI-X slots within the same system unit or I/O unit/drawer/tower</p><p>For 8204-E8A: IBM i Power 6, 8204 (#5583)</p><p>Minimum required: 0</p><p>Maximum allowed: 36 (Initial order maximum: 36)</p><p>OS level required: IBM i V5R4 with V5R4M5 Machine Code, or later.</p><p>Initial Order/MES/Both/Supported: Both</p><p>CSU: Yes</p><p>Return parts MES: No</p><p>Note: Not supported in CEC.
