#5582/5583 Controller with 1.5GB Auxiliary Write Cache without IOP
The #5582/5583 Controller with 1.5GB Auxiliary Write Cache without IOP provides a disk controller with auxiliary write cache to
improve cache data redundancy. The #5582/5583 includes a #5777 PCI-X disk controller and a secondary IOA with 1.5 GB of
auxiliary maximum compressed write cache. The #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, or 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, or tower in which the #5777 is installed. No disk drives are driven by the
auxiliary write cache IOA.
The #5583 and #5582 are physically the same adapter cards but have different feature numbers that denote to IBM
configurator tools whether an IOP is required. The #5583 does not require an IOP.
Minimum operating system level: IBM i 5.4 with 5.4.5 machine code.
The #5583 is supported in the models 9408-M25, 9409-M50, and 9406-MMA.
The #5583 is a Customer Install Feature
