A new ATCA single board computer is designed for demanding telecommunications networks where it will enable significantly faster network performance than is currently possible. Typical applications include Control Plane functions for WiMAX, LTE (Long Term Evolution) and NGN (Next Generation Networks) networks. The A10200 ATCA SBC from GE Fanuc Intelligent Platforms features two Intel Xeon Nehalem 5500 Series dual or quad core processors and up to 64 Gigabytes of DDR3 SDRAM memory, and it delivers a combination of unsurpassed performance and low power dissipation. 

For LTE applications, the A10200 is suited for Mobility Management Entity (MME) and Home Subscriber Server (HSS). MME has a stringent requirement for user handover latency, and the A10200 with its multiple processing cores, faster and less contentious memory interfaces and high-speed Ethernet connectivity options is well suited for this application. HSS holds the subscriber database and requires fast and reliable storage options, which the A10200 offers in the form of dual SAS drives. More demanding storage needs can be addressed by the use of a customized Rear Transition Module (RTM) using dual Fibre Channel interfaces.

For NGN networks, the A10200 is well suited for media gateway controller (MGC) and multiple service layer servers. MGC, also known as a SoftSwitch, is at the center of the NGN architecture and is required to maintain the call state for every call in the network. It is tasked to perform call control, gateway access control, resource allocation, authentication, charging and so on. All these functions greatly benefit from multiple cores, 64 Gbytes of memory and dual high-performance SAS storage.

Keys to the performance of the A10200—which is optionally available as a single processor platform—are the size of its memory and the implementation of an asymmetric multiprocessing (AMP) architecture. The provision of 64 Gbytes of memory allows the storage of larger routing tables in main memory, reducing the number of time-consuming routing table swaps between main memory and the database because needed routing information is missing.

The A10200’s Asymmetric Multiprocessing Architecture means that each processor has its own memory bus and access to its own (up to 32 Gigabytes) memory, reducing the processing overhead caused by contention and bus sharing in platforms using Symmetric Multiprocessing Architecture (SMP).

Also contributing to the A10200’s leading-edge performance is its support for multiple Gigabit Ethernet and 10 Gigabit Ethernet interfaces, together with a Gigabit Ethernet maintenance port for remote management and trouble-shooting. The A10200 benefits from its implementation of Intel’s new 82599 Ethernet controller, which includes a new 40 Gigabits/second PCI Express interface and the ability to deliver up to a 250% improvement in network throughput.

Furthermore, the 82599 controller has sophisticated load sharing features allowing it to direct incoming Ethernet packets to a specific core within a specific processor based on hashed packet header values. This feature enables much higher data throughput due to parallel processing and is very valuable for systems using virtualization. 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 (Built-In Test) application package will also be available
