Apple Computer Inc. Monday announced technical details and March availability for its delayed RAID applianceand announced upgrades to the Xserve rack-mounted computer.
Xserve RAID has three models, with 720GB at $5,999, 1.26TB at $7,499, and 2.5TB at $10,999, officials said. All of the models have 8MB of on-drive cache; dual 2G-bps Fibre Channel ports; a dedicated bus for each ATA drive; and support for Apple-developed hardware acceleration of RAID levels 0, 1, 3, 5 and 0+1, they said.
