IBRIX Delivers Exceptional Input/Output Performance Density in Live Product Demonstration at LinuxWorld.

BILLERICA, Mass. -- E[acute accent]IBRIX Fusion(TM) To Demonstrate Over 1 Gigabyte Per Second Throughput from Single Directory with Only Eight Servers. Live demonstration scheduled for LinuxWorld in Boston.

E[acute accent]IBRIX(TM), Inc., inventor of the Segmented File System(TM), today announced that they will be demonstrating I/O throughput exceeding one gigabyte (GB) per second from a single directory and single namespace at the LinuxWorld Conference and Exposition in Boston, February 14-17, 2005. This performance is achieved for both read and write operations with only eight industry-standard Intel-based servers and utilizing standard interconnects and storage. The IBRIX Fusion Software Suite, which includes a fully-integrated parallel file system, logical volume manager and high-availability features, is an economical, easy-to-use, multi-purpose solution that delivers linear scalability on throughput and capacity thus enabling increased productivity, faster data analysis, and more accurate business decisions. E[acute accent]"The advent of cluster-based computing architectures is driving the need for performance and scalability from cluster file system solutions." said Shaji John, President and CEO of IBRIX. "IBRIX's segmented architecture provides performance that not only is exceptional, but also scales with number of nodes and storage under management. No other file system today offers comparable performance, scalability, and TCO results." E[acute accent]Details about IBRIX Fusion and similar performance results done with standard hardware configurations have been published in an article within the February 2005 issue of Dell Power Solutions magazine. The article is titled "Achieving Scalable I/O Performance in High-Performance Computing Environments. A downloadable PDF copy of the article is available at www.ibrix.com.
