<p>(#5582) - 5738 Ctlr w/Auxiliary Write Cache</p>
<p>Provides a disk controller with auxiliary write cache to improve cache data redundancy. #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. </p>
<p> </p>
<p>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.</p>
<p> </p>
<p>The 5582 feature is supported on the following IBM iSeries AS400 Systems: 9406-52X, 9405 & 9411 models</p>
<p> </p>
<p>#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.</p>
<p> </p>
<p>Attributes provided: Disk controller with auxiliary write cache</p>
<p>Attributes required: IOP and two PCI-X slots within the same system unit or I/O unit/ drawer/tower</p>
<p>OS level required: i5/OS V5R3, or later.</p>
<p> </p>
<p>Note: #5582 can not be installed in the model 520 CEC.</p>
