Performance Technologies Announces CGL 4.0 Registration for NexusWare® Linux® Distribution

Press Inquiries

Rochester, NY - April 14, 2008 - Performance Technologies (NASDAQ: PTIX), a leading developer of communication platforms and systems, today announced that its Linux® OS and development environment, NexusWare®, has met the Carrier Grade Linux (CGL) 4.0 requirements specified by the Linux Foundation. NexusWare V12 is based on the 2.6.20 Linux kernel and conforms to OpenHPI, an open source implementation of the Service Availability Forum’s Hardware Platform Interface (HPI).

The specifications set forth by the Linux Foundation define a consistent functionality that meets the demands of complex networking applications. A variety of requirements are included in the CGL 4.0 specification including extended POSIX compliance. This is designed to ease application portability for mainstream communications applications moving to Linux environments. In addition, the CGL standard consists of categories defined by the Linux Foundation that include performance, hardware, standards, serviceability, availability, security, and clustering. New in CGL 4.0 is the prioritization of these requirements. Each requirement is now defined as either mandatory, desired, or roadmap items. By achieving CGL 4.0 registration, Performance Technologies becomes one of only three companies whose software meets this specification.

NexusWare provides a common, pre-integrated Linux OS and development environment for Performance Technologies’ embedded products that include CompactPCI® and MicroTCA™ application-ready platforms, x86 and PowerPC® single board computers, voice processing, TDM and sync serial communications, storage, switching, and system management hardware components. Equipment manufacturers can leverage the company’s pre-integrated hardware and software solutions to shorten time-to-market and eliminate costly and unnecessary integration steps.

"Performance Technologies believes strongly in the direction the Linux Foundation CGL Work Group is headed with carrier-grade registration as Linux plays a key role in migrating customers off proprietary systems and onto COTS platforms," said Steven Wigent, product manager for Performance Technologies. "Developers in telecommunications, aerospace and defense, as well as commercial industries demand robust software that facilitates maximum availability and scalability to their systems. Our NexusWare software meets this demand, and CGL 4.0 registration demonstrates this."

System architects and design engineers needing advanced, compute-intensive embedded solutions, including the company’s newly launched MicroTCA™ platform, the MTC5070, can meet with Performance Technologies representatives at the Embedded Systems Conference Silicon Valley, McEnery Convention Center, San Jose, CA, from April 15-17, 2008, in booth 1510.
