The IBM Power6 8203-E4A (#5777) PCI-X Disk Controller-1.5GB No IOP</p><p>(Available in Refurbished Condition Only as of August 28, 2009) </p><p></p><p>Provides a high-performance PCI-X Ultra320 SCSI disk controller with a maximum compressed write cache of 1.5GB and read cache of 1.6GB. #5777 will support i5/OS mirroring protection for internal disk drives using the write cache, but will not use the write cache to run RAID-5 or RAID-6 unless an auxiliary write cache IOA is attached. Running RAID-5 or RAID-6 without write cache very significantly reduces its performance. (When an auxiliary write cache IOA is attached, the pair of cards is denoted by feature code #5583.) Concurrent battery maintenance is supported. The controller also supports internal tape units, CD-ROM units, and DVD units. The #5777 has four internal Ultra320 SCSI buses and does not require an IOP. </p><p></p><p>Attributes provided: High performance disk controller </p><p>Attributes required: A single long PCI-X slot </p><p>For 8203-E4A: The IBM Power6 8203-E4A (#5777) </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: This adapter is not allowed in the CEC.
