IBM i Power 6, 8204 (#5776) PCI-X Disk Controller-90MB No IOP

(Refurbished Condition Only as of August 28, 2009)

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 or 24 disk drives and up to two internal removable media devices (tape, DVD-ROM, or DVD-RAM) are supported on the #5776. The maximum is 12 drives in a #0595 I/O drawer. The maximum is 10 drives in a #5094/5294. The maximum is 24 drives in an EXP24 Disk Enclosure. The #5776 can attach to disk drives within an expansion tower and also attach to disk units in an EXP24 Disk Enclosure. The #0301 specify indicates to the IBM Configurator tool that one port of the #5776 is attaching to disk units in an EXP24 Disk Enclosure.

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.

Note the 757MB write cache and 1.5GB write cache disk controllers provide greater disk performance and have an auxiliary write cache IOA to protect the write cache contents.
