The IBM Power6 8203-E4A (#5776) PCI-X Disk Controller-90MB No IOP

(Available in 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.
