Apple has updated its 1U rackmount Xserve; the company claimed the new server is up to twice as fast as its predecessor.

The Xserve is configurable with up to two Quad-Core Intel Xeon 5400 processors running up to 3.0 GHz with 12MB of L2 cache per processor.

Like the Mac Pro, the Xserve features a new high-bandwidth hardware architecture, dual-independent 1600 MHz front side buses and up to 32GB of 800 MHz DDR2 ECC FB-DIMM memory. This gives the Xserve a 64 percent increase in memory throughput, Apple said.

With two PCI Express 2.0 expansion slots the Xserve has up to four times the I/O bandwidth of the previous Xserve to support the latest high-bandwidth expansion cards including multi-channel 4Gb Fibre channel and 10Gb Ethernet cards.

Xserve also includes built-in accelerated graphics to drive up to a 23-inch Apple Cinema Display and a new front-facing USB 2.0 port.

The Xserve is available now with US pricing starting from $2,999 (£1,504)
