MISSION CRITICAL LINUX DELIVERS HIGH AVAILABILITY TO INTEL'S

-- First Linux HA Cluster to be Ported to Intel's New Technology --

LinuxWorld Expo, San Jose, Calif. - August 15, 2000 - Mission Critical Linux, Inc., the cutting-edge Linux products and services company, has become the first to port Linux HA clustering technology to Intel's IA-64 architecture. Utilizing a Convolo Cluster built on Open Source Kimberlite technology developed by Mission Critical Linux, high availability is provided to applications such as the Open Source MySQL database and Apache web servers running on IA-64. The combined system is being demonstrated in the Intel Booth (#1044) at LinuxWorld San Jose and at several other upcoming industry events, including the Intel Developers Forum August 22-24 in San Jose. Implemented as a back-end HA system for dynamic data, the IA-64/Convolo Cluster is seamlessly integrated with an IA-32 Intel web server farm.

"The porting of our clustering capabilities to IA-64 is attracting significant industry interest," said Brian Stevens, Vice President of Internet Strategy at Mission Critical Linux. "The combined technology creates a powerful solution for achieving high availability and raw computing power in high-end databases."

         The system being demonstrated uses a Convolo Cluster to guarantee high availability for front-end, Intel-based servers. The redundant web servers access the main databases through a two-node

cluster configuration that uses RAID-protected shared storage disks to ensure the integrity of dynamic data during transactions. The cluster server nodes, which are connected to a shared RAID storage
controller, keep track of all dynamic data entering the databases; when one node shuts down or fails, the
other node accesses the disk and uses transaction logs to recover the database and continue operation. By leveraging advanced Kimberlite technology, the Convolo Cluster can match the performance of proprietary cluster systems in providing high availability without data corruption in enterprise computing environments.

IA-64 and Intel® ItaniumTM Processors
Intel's IA-64 is a new enterprise processor architecture designed from the ground-up to meet the needs of the Internet economy and high-end server and workstation application requirements. Platforms based on the first processor in the IA-64 family, known as the Intel Itanium processor, are being designed to deliver higher levels of scalability, performance, and availability. The advanced features of the Itanium processor platform combined with its breadth of industry support and IA-32 instruction set compatibility will benefit enterprise and technical computing applications such as enterprise resource planning, decision support, scientific computing, and mechanical design.
        
"High-performance clustering technology using open industry standards has become an efficient means to achieving high availability for demanding enterprise and technical computing applications," said Jason Waxman, Intel IA-64 marketing manager. "The combination of Mission Critical Linux's cluster technology running on Intel Itanium processor platforms will deliver the scalability, flexibility, and high availability that is critical to the emerging computing requirements of today's businesses."
