FOR PERFORMANCE TECHNOLOGIES' 32-PORT FAULT TOLERANT ETHERNET SWITCH SAN JOSE, Calif. -- February 9, 1999 -- The new Virtex field programmable gate array (FPGA) from Xilinx (NASDAQ:XLNX) is enabling Performance Technologies (NASDAQ:PTIX), a leading supplier of high availability networking switching solutions, to add Gigabit functionality to PTI's Nebula family of high performance, fault tolerant Ethernet switching products. The Xilinx Virtex XCV1000 device is a million-gate FPGA which provides a significant portion of the functionality required to build a two-port wire speed Gigabit switch that interfaces to Pulsar, PTI's proven ASIC-based switching fabric. PTI's Ethernet switch family includes the industry's first truly fault tolerant backbone switch, the 32 port Nebula 8000 switch, which uses unique mirroring techniques and a sophisticated failover architecture. Other models in the family include the Nebula 4000 16-port Workgroup Switch, and the Nebula 6000 64-port High Density Departmental Switch. All switch models include features such as hot swappable load sharing power supplies, port trunking, embedded HTTP server for network management, sophisticated VLANs, Quality of Service support, advanced security/filtering, high-speed WAN access, industry standard WAN and LAN interfaces and the standard full-duplex Gigabit uplink ports using the Virtex XCV1000 FPGA. PTI's Nebula 8000 Fault Tolerant Switch is particularly unique in its class and is ideally suited for mission critical "round-the-clock" applications environments such as banking, brokerage, medical, government, transaction processing or other business/mission critical applications. The Virtex family comprises the industry's first FPGAs that address system-level design issues. The Virtex devices offer a robust feature set with densities ranging from 50,000 to one million system gates. The million-gate Virtex FPGAs -- an industry first at this density -- and other Virtex family members are available now. "We did an exhaustive search and found that only the Xilinx Virtex FPGAs could provide us with the performance and density necessary to add Gigabit capability to the Nebula switch family," said John Peters, vice president of development at Performance Technologies. "We were very impressed with the system level capabilities of the Virtex FPGAs, particularly the digital delay locked loops and support for multiple I/O standards." About Performance Technologies
