Extreme Performance ATCA Blade with Dual Intel Xeon Processors E5-2658 and E2648L
Page 1 of 1
An AdvancedTCA (ATCA) processor blade features robust computing power, high throughput connectivity and accelerated packet processing capabilities. The aTCA-6250 from Adlink Technology incorporates dual 8-core Intel Xeon processors E5-2658 and E2648L (2.1 GHz/1.8 GHz) with the Intel C604 chipset, eight channels of DDR3 memory up to 128 Gbyte, and a 400W power supply subsystem. The aTCA-6250 also provides versatile connectivity, including dual 10GbE Fabric Interfaces, dual GbE Base Interfaces, quad front panel GbE interfaces, dual front panel USB and COM ports, and onboard SATA DOM socket. Dual 10GbE ports and dual hot-swappable SAS bays on the optional aTCA R6270 Rear Transition Module (RTM) provide additional network throughput and storage capabilities.
The aTCA-6250 implements dual Intel Xeon processor E5-2658 and E2648L-based devices linked by dual Intel Quickpath Interconnect (Intel QPI) point-to-point link interfaces providing high bandwidth, low latency connectivity from processor to processor at up to 8 GT/s. With Intel Hyper-Threading Technology and Intel Turbo Boost Technology, the Intel Xeon processors E5-2658 and E2648L provide increased performance from both single and multi-thread workloads while maintaining thermal and energy efficiency. Eight sockets of DDR3-1600 VLP RDIMM offer a maximum capacity of 128 Gbyte of main memory. The memory design of the aTCA-6250 is optimized for maximum memory bandwidth and provides forward compatibility with next generation DDR3-1866 memory supported by future Intel CPU designs.
High-speed data transfer on the PICMG 3.1 Fabric Interface is enabled by a PCI Express 2.0 capable Intel 82599EB 10GbE controller, and Base Interface connectivity is provided by PCI Express 2.0 capable Intel 82576EB GbE controllers. Paired with the optional aTCA-R6270 RTM, the aTCA-6250 supports additional dual 10GbE SFP+ ports enabled by an Intel 82599ES 10GbE controller.
The aTCA-6250 supports the Intel Data Plane Development Kit (Intel DPDK), a lightweight run-time environment for Intel architecture processors offering low overhead and run-to-completion mode to maximize packet processing performance. It provides a rich selection of optimized and efficient libraries, also known as the Environment Abstraction Layer (EAL), which are responsible for initializing and allocating low-level resources, hiding the environment specifics from the applications and libraries, and gaining access to the low-level resources, such as memory space, PCI devices, timers and consoles.
The EAL provides an optimized Poll Mode Driver (PMD); memory & buffer management; and timer, debug and packet handling APIs, some of which may also be provided by the operating system. To facilitate interaction with application layers, the EAL, together with standard the GNU C Library (GLIBC), provide full APIs for integration with high level applications.
