SAN FRANCISCO Intel Corp. and Emulex Corp. announced a family of integrated storage controllers based on Intel's Xscale processor, aiming to scoop up the market for standalone interface chips from companies like LSI Logic Corp.
Intel will sell versions for the Serial ATA and Serial Attached SCSI (SAS) interfaces; Emulex will sell controllers spun for Fibre Channel.
The controllers process interface protocols and storage applications such as RAID on one or more Xscale cores. The chips, made by Intel, use the 90-nm Monzano version of the core, running at up to 1.2 GHz.
"Adapter cards that could require three to five chips can now be built with just one," said Brian Reed, a vice president of business development at Emulex.
The Intel parts have up to eight SATA or SAS ports. The Emulex versions sport up to four Fibre Channel ports at 4 Gbits/s. The controllers use a combination of host interfaces, including PCI X 1.0 and 2.0 and PCI Express. The chips support up to 2 Gbytes external DDR2 memory running at up to 533 MHz.
The Intel IOP34x family ranges from $53 to $152, depending on the number of cores and functions. The chips are sampling now and will be in volume production by the end of the year.
ATTO Technology Inc. has announced two SAS adapter cards for the Express bus using the Intel chips.
