2763 PCI Raid Disk Unit Controller

Condition : Refurbished

In addition to providing RAID-5 protection for disks, #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.
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 10 disk units allowed per one 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 six disk units.
See the Disk Unit Table for a list of disks that can be placed into RAID-5 arrays.
