Learn about the specifications for the PCI-X Ultra RAID Disk Controller.
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 feature code (FC) 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 FC 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 FC 2780.
