PCI-X Ultra4 RAID Disk Controller (FC 0627, 0641, 2780; CCIN 2780)

This adapter is an Ultra4 (Ultra320) SCSI controller with a maximum compressed write cache of 757 MB and a maximum compressed read cache size of 1 GB that provides RAID-5 protection for internal disks and also supports internal tape units, CD-ROM and DVD units. The 2780 has four Ultra4 (Ultra320) SCSI buses. In addition to providing RAID-5 protection for disks, it is also designed to work as a high performance controller for disks protected by system mirroring or disks with no protection. This controller also uses a Cache Battery Pack, which can be replaced concurrently with system operation.

A 5708 or 574F Auxiliary Cache IOA is required for RAID. The Auxiliary Cache IOA is to be connected to the 4th SCSI bus of the 2780.

The 0627 is a direct attach 2780 for use with Linux or AIX®.

The 0641 is a direct attach 2780 with a CCIN 574F auxiliary-write cache IOA.
