Concurrent iHawk Featuring Xeon Blade Technology Now Available; iHawk Series 880 Blades Offers Highly Scalable Solution for Applications Requiring Large Number of Processors.

ATLANTA -- Concurrent Computer Corporation (NASDAQ: CCUR), a leading provider of integrated computer solutions for mission-critical applications, today announced availability of its iHawk(TM) Series 880 multiprocessing systems featuring Intel(R) Xeon(TM) blade technology.

Series 880 blades provide highly scalable, flexible and cost-effective configurations for applications requiring a large number of processors in a small space. Concurrent iHawk blades are an excellent choice for distributed data acquisition or simulation. Once a solution is developed using a blade platform, additional processing power can be added to meet future requirements without major re-engineering.

Each ultra-slim iHawk processor blade is itself a two or four-CPU Xeon SMP system running Concurrent's RedHawk(TM) Linux(R) operating system. Up to fourteen processor or I/O blades can be configured in a single 7U rackmount chassis. iHawk processor blades can be interconnected using Gigabit Ethernet. Series 880 also features Concurrent's Real-time Clock & Interrupt Module (RCIM), ideal for time-critical applications requiring rapid response to external events.

iHawk processor blades offer on-board disk drives along with a range of add-on SCSI drive blade options. Each processor blade can also be configured with two 64-bit 100 MHz PCI-X slots, providing up to fourteen PCI slots per chassis. Series 880 blades are fully supported by RedHawk Linux and Concurrent's NightStar(TM) tool set. Processor blades can also be interconnected using fabrics such as InfiniBand or Myrinet for high-speed, low-latency inter-blade communication. Fabric interfaces and supporting cluster protocol software will be supported in an upcoming release of RedHawk Linux.

"Concurrent's latest blade technology further demonstrates the company's continued growth and evolving platforms designed to support a wide spectrum of high performance applications," said Warren Neuburger, Concurrent Chief Operating Officer. "The iHawk Series 880 provides users with a highly deterministic platform for a diversity of markets, including business, financial and medical sectors, as well as traditional real-time simulation and data acquisition markets."
