The SHB line of PCI Express-based solutions includes dual- and single-processor single-board computers (SBCs). It includes NLT boards with Xeon processors that support the 64-bit Intel Extended Memory Technology (Intel EM64) and an 800-MHz processor bus. Edge connectors provide two x8 PCI Express links, one x4 PCI Express link, and five PCI Express reference clocks. The NLT board features dual SATA/150 interfaces, quad USB 2.0, dual 10/100/1000BaseT Ethernet ports, onboard video, and an optional I/O expansion board for legacy I/O support. The SHB backplane features one x16 and one x8 PCI Express slot. A PCI Express-to-PCI/PCI-X bridge supports four 64-bit/66-MHz PCI-X slots. A PCI bridge supports an additional four 64-bit/33-MHz PCI slots. Pricing for the NLT Dual processor SHB is $2675. The NLI Single processor SHB costs $2275. The BPX3/8 SHB Express Backplane is $832.
