Broad Industry Support Signals Maturity, Enterprise Demand for Open-Source Cluster File System.

SAN FRANCISCO -- September 19, 2005 -- Red Hat, Inc. announced today that Red Hat Global File System (GFS) is now supported by Oracle for use in Oracle RAC solutions, EMC CLARiiON® networked storage systems, EMC Celerra® iSCSI network attached storage (NAS) systems solutions, and NetApp for SAN interface solutions. Red Hat GFS is the first third-party cluster file system supported by Oracle for RAC solutions on Linux.

"Commercial users don't want to be lab rats. The endorsement of GFS by some of the biggest players in the market signifies this solution is really ready for prime time,” said Steve Duplessie, founder and senior analyst at The Enterprise Strategy Group, Inc. "I expect we'll see lots of large deployments in the very near future."

Red Hat GFS is the open-source cluster file system designed for high-performance enterprise workloads, such as Oracle RAC, Web and application server clusters. GFS makes it possible to manage a cluster of servers and shared storage as if it were a single system, by providing a common cluster-wide file system. Having a common file system eliminates conflicts and problems that arise when different servers want to access the same file at the same time.

Red Hat GFS is the only native 64-bit cluster file system on Linux for enterprise workloads, with support for x86, AMD64/EM64T, and Itanium. It's also the most scalable enterprise-cluster file system on Linux, supporting up to 300 nodes. GFS is tightly integrated with Red Hat Enterprise Linux, and it is POSIX-compliant, meaning that customers do not have to rewrite applications to use GFS.

"When customers run Red Hat GFS combined with the Oracle Grid solution on servers based on the Intel® Itanium®2 processor or on the 64-bit Intel® Xeon™ processor with Intel® Extended Memory 64 Technology (EM64T), enterprises benefit from a reliable, secure, high-performance platform designed for today's demanding commercial environments.", said Gregory Symon, director of global software solutions, Intel Corporation.

"Red Hat GFS has been qualified as E-Lab™ Tested by EMC Corporation for use with EMC CLARiiON networked storage systems and EMC Celerra iSCSI NAS systems. "The EMC E-Lab Tested Program is the most comprehensive qualification program in the industry," said Tom Joyce, EMC vice president, storage platforms marketing. "EMC’s rigorous testing provides assurances of interoperability as customers build and deploy solutions using Red Hat GFS with EMC CLARiiON and EMC Celerra systems and software."

"NetApp is committed to providing the most compelling solutions that address customers' pressing data management needs," said Patrick Rogers, vice president of partner and alliances marketing at Network Appliance. "NetApp support of Red Hat GFS running over our SAN interfaces provides an important new alternative for customers seeking a scalable file system for Linux environments, while retaining the NetApp advantage of simplified data management, through our unique storage technologies."
