JNI Corporation Announces InfiniStar™ Support for the Upcoming AMD Opteron™ Processor and 64-bit Linux

JNI’s InfiniStar 4X HCA Modules and AMD 64-bit technology provide reliable solutions that enable server clustering at 10 Gb/sec speeds.

San Diego, CA -- 11/18/2002 -- JNI Corporation (NASDAQ: JNIC), the first company to introduce 4X Infiniband HCA Modules, has announced the support and integration of JNI HCA modules with the upcoming AMD Opteron™ processor based on Hammer technology.

“Bringing together these two innovative products offers customers optimized 32-bit performance and 64-bit support in the same environment,” said Shaun Walsh, vice president and general manager of I/O Solutions, JNI Corporation. “Working with AMD, JNI is bringing together many of the major components required to build InfiniBand-based clustered server solutions and establish a foundation for widespread InfiniBand deployment.”

To meet the I/O needs of the enterprise environment, JNI and AMD support the InfiniBand Architecture (IBA), an open standard for moving high volumes of data between processors and I/O devices. JNI InfiniStar modules coupled with the AMD Opteron™ processor-based platform are expected to deliver excellent scalability and performance for x86 Linux clusters used for scientific computing and database applications.

"JNI's HCA products and 64-bit Linux support will help customers with the speed and ease of building high performance computing and database clusters with InfiniBand technology," said Ed Gasiorowski, director of developer relations for AMD’s Computation Products Group. “The upcoming AMD Opteron processor offer customers stability, reliability and excellent performance while protecting investments in existing infrastructure and applications."

JNI HCA Modules
JNI offers three separate InfiniStar™ HCA modules for server clustering: the IBP-1x02 is a PCI, dual-port module that incorporates the Mellanox InfiniBridge ASIC and supports link speeds up to 2.5 Gb/sec (1X) per port; the IBX-4x02i is a PCI-X, dual-port module based on the new IBM Microelectronics InfiniBlue ASIC and supports link speeds up to 10 Gb/sec (4X) per port; the IBX-4x02m is also a 4x, dual-port, PCI-X module based on the new Mellanox Technologies InfiniHost ASIC.

InfiniBand HCA modules are similar to Fibre Channel host bus adapters (HBAs) in that they enable the creation of scalable, extensible networks by sharing resources outside the host server. Server networks connected via the high-performance, low-latency InfiniBand interconnect are widely expected to replace Symmetric Multi-Processor (SMP) systems for many compute and I/O intensive applications, such as High-Performance Computing Clusters (HPCC) and parallel database clusters.

JNI's InfiniStar IBP-1x02 HCA Module is the first InfiniBand product to be incorporated into an OEM enterprise data center solution, the FAS900 series enterprise storage systems from Network Appliance. Early access versions of the new 4x HCA modules are currently available for OEM evaluation and qualification. General availability of new modules is planned for the first quarter of 2003, including full InfiniBand protocol support for the Linux operating system.
