Detailed Description

(#2763) PCI RAID Disk Unit Controller (270, 720, 8XX, 250, 5101, 5065, 5074, 5075, 9074, 9075)This controller with a 10MB write-cache, provides RAID-5 protection and compression for internal disk units, and also supports internal tape and CD-ROM units.

#2763 does not support #4331/#6831 (1.6GB Read Cache Device)or disk compression

The #2763 controller supports a maximum of 12 disk units. A minimum of four disk units of the same capacity are needed for a valid RAID 5 configuration. A maximum of three arrays are allowed per controller, with a maximum of ten disk units allowed per array. All disk units in an array must be of the same capacity. Parity is spread across four disk units for arrays of four to seven disk units. Parity can be spread across either four or eight disk units for arrays of eight to ten disk units. Systems with eight to ten disk units in an array find the parity, for that array, spread across eight disk units. For systems with fewer than eight disk units in an array, and later upgraded to eight, nine, or ten disk units, the RAID function must be stopped and then started before parity will be spread across eight disk units.

For best performance use disks, disk controllers, and storage expansion devices capable of Ultra2 SCSI performance.

Prerequisites: Requires a full length card slot.
