#5583 #5583 (5777) Controller with Aux Write Cache
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 1.5 GB 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 can 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
Attributes required: Two PCI-X slots within the same system unit or I/O unit/drawer/tower
