(#5782) - PCI-X EXP24 Ctl-1.5GB No 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.

This feature includes a double-wide blind swap cassette in which the disk controller is placed. The cassette is required to locate the disk controller in a 570 system unit or #5790 I/O drawer.

#5782 and #5781 are physically the same adapter card but have different feature numbers to denote to IBM configuration tools whether or not an IOP is required. #5782 indicates an IOP is not used. #5739/#5778 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 model 520 system unit and has a light pipe inserted into the feature.

• Attributes provided: High-performance SCSI RAID controller in a double wide
• Attributes required: Two adjacent PCI-X long card slots, in a blind swap cap.
