Intel develops Atom for storage

Intel has revealed that work on its new Atom processor designed for the storage market will be in the shops next year.

Codenamed Briarwood, Intel says that the chip is designed to run storage area networks and provide storage building block products. According to Decrypted Tech, the chips are based around two Saltwell x86 cores with support for virtualisation and HT (4 logical cores) and single channel DDR3 memory controller with support for ECC.

Intel techies have shoved the Crystal Beach DMA engine under the bonnet so that it can handle support for RAID 5 and 6, and DIF.

Briarwood will have a 1 MB L2 cache, and are otherise similar to Centerton, designed for servers.

Intel said there will be three versions of the the processors, two will have a 1.6 GHz clock speed.

One of these slower clips, the Atom S1269, will have 32 PCI Express 2.0 lanes, and an 11.7 watt TDP. The other one, the Atom S1279 will have 40 PCI Express 2.0 lanes and a 13.1 Watt TDP.

A third chip, the Atom S1289 has a slightly higher clock speed of 2 GHz and an analogous higher TDP set at 14.1 watts. Otherwise it will be similar to the S1279.

The chips are fairly close to Centerton chips but Intel hopes they will become popular due to their low power consumption and compatibility with x86.
