#2763 PCI RAID Disk Unit Controller

The #2763 is an Ultra2 SCSI disk unit controller with a 10 MB write-cache that provides
RAID-5 protection for internal disk units and also supports internal tape and CD-ROM units.
In addition to providing RAID-5 protection for disks, the #2763 is also designed to work as a
high-performance controller for disks protected by system mirroring or disks with no
protection. In the RAID-5 configuration, disk unit protection is provided at less cost than
mirroring and with greater performance than system checksums.
The #2763 controller supports a maximum of 12 disk units. A minimum of four drives of the
same capacity are needed for a valid RAID-5 configuration. A maximum of three arrays are
allowed with a maximum of 10 drive allowed per array. All drives in an array must be of the
same capacity.
The #2763 supports two removable media devices.
This feature also supports Hot Pluggable.
Refer to card placement rules for supported systems and valid slots.
