Red Hat Global File System
for scale-out web services
Red Hat leads the way in delivering open source storage management for Linux with the integration and support
of LVM, ext3, NFS, autofs, volume mirroring, I/O multipathing, and more. Capabilities found in technologies like
LVM, LVM2 and ext3--the default now for most enterprise Linux implementations--are, in great part, due to the
e?ort of Red Hat-sponsored community engineering e?orts.
The delivery of an even greater set of storage management capabilities like those found in Red Hat? Global
File System (GFS), Red Hat Cluster Suite (CS) and Distributed Lock Manager (DLM) continued with the 2005
introduction of Red Hat Enterprise Linux? 4. GFS and CS enable high availability and data sharing for key
applications like Oracle? Real Application Clusters (RAC), NFS, and Apache. The highly successful 2.6-kernel-
based LVM2 follows the 2.4 kernel-based LVM with a cluster-aware version named CLVM. CLVM is included in the
Red Hat Enterprise Linux distribution as a key part of scale out storage management.
Device Mapper and its Red Hat Enterprise Linux 4 support of multipath IO, iSCSI, and In?niBand complements
the maturing ?bre channel protocol (FCP). The promise of virtualization through Xen brings all of these
technologies together into a highly advanced storage management platform with the scheduled release with
Red Hat Enterprise Linux 5.
Open source storage management technologies are beginning to o?er an attractive alternative to expensive
proprietary solutions. Storage management capabilities found in Red Hat Enterprise Linux help customers
reduce costs and simplify complex mission-critical IT environments.
Below are two case studies of customers who have bene?ted from the deployment of open source storage
management from Red Hat. IP-Tech and Messe München have deployed a combination of GFS, CS, and Red Hat
Enterprise Linux as part of the mission-critical IT infrastructure that delivers web services to their constituents.
