(#2748) PCI RAID Disk Unit Controller

(Only available as REFURBISHED as of December 3, 2002)

The #2748 is Ultra2 SCSI capable when installed in a #5065 Storage/PCI Expansion Tower/#5066 1.8m I/O Tower or is Ultra SCSI capable when installed in the system unit or #5064/#9364 System Unit Expansion.

The #2748 has a 26MB write-cache that provides RAID-5 protection and compression for internal disk units. In addition to providing RAID-5 protection for disks, #2748 is also designed to work as a high performance controller for disks protected by system mirroring or disks with no protection.

The #2748 controller supports a maximum of 15 drives. A minimum of four drives 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 drives allowed per array. All drives in an array must be of the same capacity.

#2748 also supports #4331/#6831, 1.6GB Read Cache Device, which provides increased performance. Large read cache (#4331/#6831) is supported only when #2748 is NOT in compression mode.

The #2748 also supports combinations of CD-ROM and internal tape units. When placed in the #5064/#9364 System Unit Expansion, the #2748 can support up to three internal tape units and CD-ROM, in any combination. When placed in a #5065 Storage/PCI Expansion Tower or #5066 1.8m I/O Tower, the #2748 can support up to two tape units and CD-ROMs, in any combination.

#2748 supports both compression and non-compression modes. The mode of operation is determined by a hardware jumper. #2748 is shipped with the jumper set for non-compression mode. By moving the jumper, the controller will function in compression mode.

Prerequisite: System unit or #5064/#9364 with #9330. High-Speed PCI card slots required: One. Maximums: One in the 503X Migration Tower I, one in the #9330, three per #5065, or six per #5066.

Note: When dealing with card placement within the #5034/#5035 Migration Tower I and #9329, a #2748 can be ordered if it will replace the existing base disk unit controller. In the case of an existing #2741 in the #5034/#5035 Migration Tower I, the #2748 can be ordered but during installation, the #2741 must be removed from the Migration Tower I and plugged into the #9329 and the #2748 would then be plugged into the Migration Tower I side.

Supported on the following systems: 600, 620, 640, 650, 720, 730, 740, 810, 820, 825, 830, 840, 870, 890, S10, S20, S30, S40
