 Product Description

IBM 5776 PCI-X Disk Ctlr-90MB No IOP

  • 90MB Cache

IBM 5776, PCI-X DASD Controller provides a PCI-X SCSI disk controller that has a 90MB write cache and can provide RAID-5 or RAID-6 protection of disk units. The #5776 has two U320 SCSI buses each with a bus data rate of up to 320MBs. A maximum of 12 internal disk drives and up to two internal removable media devices (tape, DVD-ROM, or DVD-RAM) are supported on the #5776. A minimum of three disk drives are required for RAID-5, providing protection against a single drive failure in an array. A minimum of four disk drives are required for RAID-6, providing protection against up to two drives failing in an array. #0648, #5737, and #5776 are physically the same adapter card but have different feature numbers to indicate to IBM configurator tools that an IOP is or is not being used in the configuration. Note the #5580, #5581, #5582, #5583, #5590 & #5591 disk controllers, with an effective 757MB write cache, provide greater disk performance and have an auxiliary write cache IOA to protect the write cache contents.
