5583-8203 - 5777 Controller w/Aux Write Cache

The IBM Power6 8203-E4A (#5583) 5777 Controller w/Aux Write Cache

(Available in Refurbished Condition Only as of August 28, 2009)

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.

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.

Attributes provided: Disk Controller with auxiliary write cache
