Concurrent CompactPCI SBC Supports Dual 2.4 GHz Intel Xeon Processors

6/14/2005 - Concurrent Technologies announces its latest CompactPCI single board computer - a dual Intel® XeonTM processor board. The PP 221/01x is positioned as Concurrent Technologies highest performance CompactPCI processor board and is designed as a form, fit and function continuation of the popular PP 220/01x family. The PP 221/01x offers two low power CPU speed options using the Low Voltage Intel Xeon Processor, the 2.4 GHz (533MHz FSB) works within a 40W thermal envelope and the 2.0 GHz (400MHz FSB) works within a 35W thermal envelope. Supporting up to 4 Gbytes DDR ECC DRAM, the dual 2.4 GHz processors can access memory at a peak bandwidth of 4.2 Gbytes/sec and the dual 2.0 GHz processors can access memory at a peak bandwidth of 3.2 Gbytes/sec. The PP 221/01x supports on-board Ultra-160 SCSI and UDMA100 EIDE disk interfaces and is ideally suited to intensive multitasking applications requiring scalability and high performance, such as web-serving, search engines, storage (NAS, SAN), traffic management, voice over IP, telecommunications servers, network management, security, and load balancing.

Both 2.4 GHz and 2.0 GHz processors feature 512 Kbytes L2 cache, Intel NetBurstTM Microarchitecture and Hyper-Threading technology. Hyper-Threading technology enables the PP 221/01x to function as four "virtual" processors by executing two threads in parallel on two processing cores therefore allowing the software to multi-task more effectively. Both processors connect to the high performance ServerworksTM Grand ChampionTM LE System I/OTM chipset interfacing with up to 4 Gbytes 200MHz/266MHz DDR ECC SDRAM, Ultra-160 SCSI and dual Gigabit Ethernet interfaces (sharing a 66MHz PCI bus) plus a 64-bit 66MHz PMC site and CompactPCI bridge (sharing a 66MHz PCI bus). For increased reliability, as with all Concurrent Technologies’ designs, passive heat sinks are used in preference to fans for cooling the two CPUs; the board can operate in environments ranging from 0 C to +55 C.

The PP 221/01x supports PICMG® 2.16 (Ethernet on backplane), PICMG 2.9 (IPMI), PICMG 2.1 (hot swap), PICMG 2.0 (33/66MHz CompactPCI) and can operate as a system slot controller, peripheral slot controller or as a satellite board (disables CompactPCI interface) to utilize the PICMG 2.16 Ethernet only. As well as the dual Gigabit Ethernet and Ultra-160 SCSI signaling interfaces to the J3 connector, the PP 221/01x also features EIDE interfaces (up to UDMA100) to the J5 connector and supports an onboard CompactFlashTM/MicrodriveTM socket and an optional on-board 2.5-inch disk drive. Other features provided are a PC real-time clock, floppy disk interface, 2 RS232 channels, 2 USB ports, parallel printer port, watchdog timer, keyboard/mouse interface, and a Silicon Motion SM722 graphics interface including DVI-D support. To facilitate applications requiring rear I/O connections, the PP 221/01x uses the optional AD PP4/001 transition module.

The PP 221/01x supports many of today’s leading operating systems, including Linux®, Windows Server 2003TM, Windows® XP, Windows® 2000, Windows NT®, VxWorks®, and QNX®. All of these operating systems support dual CPUs and the Xeon’s hyper-threading capability. LAN boot firmware is supported for blade applications.
