Introduction:
The VPQ is a high performance Single Board Computer (SBC) based on the 6U VPX (VITA 46) form factor. Offered in both convection cooled and ruggedized conduction cooled variants, the VPQ will meet the needs of numerous commercial and military applications.
At the heart of the VPQ is one quad-core Intel L5408 Xeon Processor, an Intel 5100 Memory Controller Hub (MCH), and an Intel ICH9R I/O Controller Hub (ICH), forming the central processing backbone of the design. Up to 4 GBytes of DDR2 SDRAM are supported with the MCH running at up to 1066 MHz double data rate speeds.
The VPQ provides unparalleled data processing capabilities. It supports two fully capable PMC/XMC Sites with extensive User I/O. An on-board Fulcrum FM3212 12-Port 10 Gigabit Ethernet Switch provides full-mesh backplane data-layer interconnectivity, allowing up to eight VPQ SBC's to be integrated into a single chassis without the use of an additional switch board. A PLX PEX8624 PCI Express Switch provides connectivity to the XMC Sites and an Intel 82599EB Dual 10 Gigabit Ethernet controller, which connects to the 10 Gigabit Ethernet Switch. The Intel 82599EB supports the IEEE 1588 Precision Time Protocol standard allowing all node boards to be synchronized in the sub-microsecond range. An 82571EB Dual 1Gigabit Ethernet controller provides MDII or 10BASE-KX connectivity to the backplane via the VPX P4 connector.
For convection cooled applications, the VPQ provides a front panel SFP+ port supporting CX4 copper and Fiber applications for chassis-to-chassis and rack-to-rack communications.
On-board non-volatile storage includes a 16 GByte Solid State Flash Drive, 16 Mbit SPI flash memory, and a 16 Mbit Firmware Hub. Four SATA, two USB, VGA, and an RS232 or RS485 Console port complement the VPQ I/O through the backplane or rear transition module.
