GE Intelligent Platforms has released the A10200 AdvancedTCA single-board computer (SBC) with the option of the latest Intel Xeon processor 5600 series, formerly codenamed Westmere-EP.

The use of the upgraded CPU provides the dual processor A10200 with up to six cores and 12Mbyte L3 cache for each CPU, enabling a processing performance improvement of up to 50 percent compared with the dual Intel Xeon processor 5500-based version of the A10200, which continues to be available.

A complement to GE's family of AdvancedTCA products, the A10200 is designed for telecommunications networks where it will be targeted at driving up network performance over that currently offered by ATCA boards.

Typical applications include Control Plane functions for WiMAX, and LTE and NGN (Next Generation Networks) networks.

The A10200 is designed to work with the company's AT2-5800 packet processor blade and provide a complete Control Plane and Data Plane processing configuration for use in such applications as session border controllers.

Within the ATCA chassis, both blades can communicate via high speed, redundant dual 10GbE and dual 1GbE networks, each of them handling the processing functions for which they are best suited and optimizing the performance of the complete system.

Key to the high performance of the A10200 is the size of its memory. The provision of 64Gbyte memory allows storing larger routing tables in main memory: it reduces the number of time-consuming routing table swaps between main memory and the database because needed routing information is missing, and contributes to much-increased system productivity.

Also contributing to the A10200's boosted performance is its support for multiple Gigabit Ethernet and 10GbE interfaces. A Gigabit Ethernet maintenance port is also provided. It also incorporates the new Intel 82599 10GbE controller, which includes a new 40Gbit/s PCIe interface and the ability to deliver up to a 250 percent improvement in network throughput.

Also, the Ethernet controller has load sharing features that allow it to direct incoming Ethernet packets to a specific core within a specific processor based on hashed packet header values, optimizing system performance. This feature enables much higher data throughput due to parallel processing and is very valuable for systems using virtualization.

Further connectivity is provided by four USB 2.0 ports, a COM port and an IPMC console port, making the A10200 exceptionally flexible and easy to configure. An accompanying TMS102 rear transitional module provides rear access two 10/100/1000Base-T Ethernet interfaces, two USB 2.0 interfaces, eight general purpose I/O ports and two on-board SAS HDDs.

The SAS controller implements RAID features that further offloads the processor cores from mundane processing, making an important contribution to overall system throughput. It is PICMG 3.1- and PICMG 3.0-compliant.

The software package provided with the A10200 includes standard BIOS, device driver, and the hardware initialization resources required to support Linux' environments. An optional run-time BIT application package will also be available.
