The system, part of IBM's eServer p610 series, supports RAID 5 in the server cabinet, instead of in a separate storage box. This design eliminates the need for power supplies and cooling fans otherwise needed for the separate box, thereby reducing energy consumption and conserving floor space, IBM said.
An added convenience of having RAID 5 support inside the server is that the external SCSI controller is left free to connect other peripherals. Competing entry-level products require an external storage device to implement RAID 5, IBM said.
RAID allows a large number of disks to be treated by the system as if it were a single storage device, providing improved data recovery if one of the disks in the array fails. The IBM eServer can contain up to 291Gbytes of internal disk storage, IBM said.
The latest addition to the eServer p610 series is priced from $5,995, (£3,659) comes in a rack-mounted and a tower version, runs AIX 4.3.3 and AIX 5L as well as Linux, and is designed to run enterprise applications. The system will be available worldwide from 22 February.
