IBM feature #2757 is the PCI-X Ultra RAID Disk Controller, CCIN 2757, a Peripheral Component Interconnect-X (PCI-X) SCSI controller with a maximum compressed write cache of 757 MB. It provides RAID-5 protection for internal disks, and it also supports internal tape units, internal CD/DVD-ROM units and internal DVD-RAM units. The controller has four LVD SCSI buses, and hardware data compression is not supported.
The adapter FRU number is 039J5057, which is not designed to comply with the RoHS requirement. The I/O bus architecture is PCI 2.2 compliant, and the card needs one available 3.3 volt PCI or PCI-X slot. Attachment cables are included with the attaching subsystem or device, and no tools are required.
The operating system requirement is IBM i V5R3 or later. The controller is used in machine types 8202, 8205, 8412, 9117, 9119 and 9179, and in the 5803 and 5873 expansion units. The 574F auxiliary-write cache IOA, which provides 1.5 GB of compressed auxiliary-write cache when paired with a RAID disk controller, can be used with the 2757.
