Trenton Technology has introduced its MCX and MCG series of system host boards (SHBs) with dual multicore processors. They are available in numerous configurations for a variety of computing applications.

The MCX series server-class boards provide multiple PCIe links for option card slots and devices on a PICMG 1.3 backplane, while the MCG series offers graphics-class board configurations with native electrical support for x16 PCIe video and imaging cards. The high-bandwidth/high-speed PCIe links designed into the MCX/MCG boards support a wide range of PCIe cards, devices and bridges for PCI-X/PCI option cards on a PICMG 1.3 compatible backplane.

Intel Xeon processors
The MCX and MCG series SHBs provide various dual-core and quad-core Intel Xeon processor options. The dual-core options provide four execution cores on a dual-processor MCX or MCG, while the Quad-Core Intel Xeon Processor E5335 option provides up to eight high-performance cores per MCX or MCG system host board. These multicore processing options target intense computing applications and extensive I/O workloads commonly found in high-end systems.

The MCX/MCG products support an independent 1066MHz (dual-core processor) or 1333MHz (dual- or quad-core processor) front side bus for each processor. The dual-core processors provide 4Mbytes of L2 shared cache, while the quad-core processors provide a 2 x 4Mbyte L2 cache. The MCX SHBs use the Intel 5000P chipset and the MCG boards use the Intel 5000X chipset.

All boards feature a four-channel DDR2-667/533 FB-DIMM memory interface. The MCX/MCG system host boards support up to 32Gbytes of system memory with a peak memory interface bandwidth of 8GBps per channel. A MCX series SHB provides two x8 PCIe links and one x4 PCIe link, while a MCG series SHB provides one x16 PCIe and one x4 PCIe link on the board's edge connectors.

PCIe link bifurcation
The SHBs support PCIe link bifurcation to maximize the available number of PCIe links on a backplane. The SHBs' PCIe links are capable of supporting communication for x1, x4, x8 and x16 PCIe cards, as well as PCI/PCI-X option cards, via a PCIe-to-PCI/PCI-X bridge chip on an SHB Express-compatible backplane.

Other MCX/MCG board features include six SATA/300 interfaces with RAID support, seven USB 2.0 connections, three 10/100/1000Base-T Ethernet ports, on-board video and connection to an optional I/O expansion board for legacy I/O support.

SHBs are available now. Pricing and processor speed availability varies. Typical prices are $2,825 for dual-processor MCXT/MCGT SHBs and $2,595 for single-processor MCXI/MCGI SHBs.
