volume manager that executes on Red Hat Enterprise Linux servers attached to a storage area network (SAN). It works on all major server and storage platforms supported by Red Hat. The leading (and first) cluster file system for Linux, Red Hat GFS has the most complete feature set, widest industry adoption, broadest application support, and best price/ performance of any Linux cluster file system today.</p> <p>Red Hat GFS allows Red Hat Enterprise Linux servers to simultaneously read and write to a single shared file system on the SAN, achieving high performance and reducing the complexity and overhead of managing redundant data copies. Red Hat GFS has no single point of failure, is incrementally scalable from one to hundreds of Red Hat Enterprise Linux servers, and works with all standard Linux applications.</p> <p>Red Hat GFS is tightly integrated with Red Hat Enterprise Linux and distributed through Red Hat Network. This simplifies software installation, updates, and management. Applications such as Oracle 9i RAC, and workloads in cluster computing, file, web, and email serving can become easier to manage and achieve higher throughput and availability with Red Hat GFS.</p> <h2>Highlights</h2> <h3>Performance</h3> <p>Red Hat GFS helps Red Hat Enterprise Linux servers achieve high IO throughput for demanding applications in database, file, and compute serving. Performance can be incrementally scaled for hundreds of Red Hat Enterprise Linux servers using Red Hat GFS and storage area networks constructed with iSCSI or Fibre Channel.</p> <h3>Availability</h3> <p>Red Hat GFS has no single-point-of-failure: any server, network, or storage component can be made redundant to allow continued operations despite failures. In addition, Red Hat GFS has features that allow reconfigurations such as file system and volume resizing to be made while the system remains on-line to increase system availability. Red Hat Cluster Suite can be used with GFS to move applications in the event of server failure or for routine server maintenance.</p> <h3>Ease of Management</h3> <p>Red Hat GFS allows fast, scalable, high througput access to a single shared file system, reducing management complexity by removing the need for data copying and maintaining multiple versions of data to insure fast access. Integrated with Red Hat Enterprise Linux (As, ES, and WS) and Cluster Suite, delivered via Red Hat Network, and supported by Red Hat's award winning support team, Red Hat GFS is the world's leading cluster file system for Linux.</p> <h3>Capabilities</h3> <ul> <li>Scalable to hundreds of Red Hat Enterprise Linux servers.</li> <li>Integrated with Red Hat Enterprise Linux 3 and delivered via Red Hat Network, comprehensive service offerings, up to 24x7 with one-hour response.</li> <li>Supports IA-32, IA-64, and AMD Opteron processors.</li> <li>Works with Red Hat Cluster Suite to provide high availability for mission-critical applications.</li> <li>Quota system for cluster-wide storage capacity management.</li> <li>Direct IO support allows databases to achieve high performance without traditional file system overheads.</li> <li>Dynamic multi-pathing to route around switch or HBA failures in the storage area network.</li> <li>Dynamic capacity growth while the file system remains on-line and available.</li> <li>Can serve as a scalable alternative to NFS.</li> </ul> <h2>Product Information</h2> <ul class="grey"> <li>Supported on Red Hat Enterprise Linux AS, ES, and WS.
