5739 - IBM PCI-X EXP24 Ctlr-1.5GB w/IOP

Provides an EXP24 disk controller with PCI-X DDR technology, a maximum of 1.5GB compressed write cache, and a maximum 1.6GB compressed read cache. The controller supports RAID-5 and RAID-6 and mirroring is supported via i5/OS. Embedded auxiliary write cache and concurrent battery maintenance are provided. The controller is implemented using two physical cards that are firmly connected and requires two adjacent PCI slots. It provides three Ultra320 SCSI ports/buses for the attachment of disk drives located in a #5786/ #5787 TotalStorage EXP24 Disk Drawer/Tower.

#5739 and #5778 are physically the same adapter cards but have different feature numbers to denote to IBM configuration tools whether or not an IOP is required. #5739 indicates an IOP is used. The #5781/#5782 and #5799/#5800 are also the same adapter cards, but the #5781/#5782 indicates the adapter is placed in a double-wide blind swap cassette and #5799/#5800 indicates the adapter is placed in a system unit and has a light pipe inserted into the feature.

The 5739 feature is supported on the following IBM AS400, iSeries & Power Systems: 9405-520, 9406-520, 9406-550, 9406-570, 9406-595, 9406-8XX, 9408-M25, 9409-M50, 9411-MMA
