SBC suits intensive data transfer

Concurrent Technologies' VP 426/23x single board computer effectively provides four processor cores.

Concurrent Technologies has released a dual-processor, 6U VME64/VME320 single board computer.

The VP 426/23x features two 1.66GHz dual-core Intel Xeon ULV processors, effectively providing four processor cores.

The board provides up to 8Gbyte onboard DDR2 ECC dual-channel SDRAM and features a variety of I/O interfaces which can be further expanded via the board's PMC/XMC site, whilst still maintaining a single-slot solution.

This combination of high-performance data processing, a large amount of memory and flexible I/O interfaces ensures that the VP 426/23x has one of the highest VME dual-processor specifications available today.

It is therefore an ideal choice for intensive data processing applications within the communications, defence, security, telemetry, scientific and aerospace markets.

An extended temperature version is also available.

The Intel E7520 server class chipset and Intel 6300ESB ICH are used to complement the two dual-core Xeon processors to achieve a high-performance, yet low-power, dual-processor, dual-core architecture.

Each Xeon interfaces to the E7520 via a 667MHz front side bus.

The E7520 chipset can access up to 8Gbyte DDR2-400 ECC dual-channel SDRAM at up to 6.4Gbyte/s, and supports up to 4Gbyte soldered and up to 4Gbyte SODIMM, all in a single slot.

For I/O flexibility there is a PMC/XMC site supporting both front and rear I/O, two SATA150 interfaces, two graphics interfaces, four Gigabit Ethernet interfaces, making the VP 426/23x ideally suited to intensive data transfer as well as data-processing applications.

The PMC site supports up to 66MHz PCI operation and also supports a x8 PCI Express XMC interface.

To sustain fast control/data rates across the VME backplane the VP 426/23x also supports the VME320 (2eSSt) protocol.

For fast transfer of system-wide data, the four channels of Gigabit Ethernet can sustain full-duplex Gigabit data rates as each dual channel Ethernet Controller is connected to its own x4 PCI Express link.

For ease of system integration the two rear Ethernet channels can be configured to connect to a VITA 31.1 Gigabit Ethernet backplane or, alternatively, connect to the board's optional rear transition module.

A wide range of onboard I/O is available to the user: the front panel supports dual Gigabit Ethernet, a USB 2.0, RS 232, analogue graphics, keyboard and mouse interfaces.

As well as the PMC rear I/O and dual Gigabit Ethernet, the rear panel supports three more USB 2.0, two more RS-232, two SATA150, two EIDE, digital graphics, keyboard and mouse interfaces.

Other features included are a watchdog timer, LAN boot firmware and options for an onboard 2.5-inch SATA150 (or EIDE) hard disk drive or CompactFlash EIDE storage.

For embedded systems, an optional fixed USB flash drive is available on the rear transition module.

For ease of integration, the VP 426/23x family supports operating systems including Linux, Windows Server 2003, Windows 2000, Windows XP, Solaris, LynxOS and QNX.
