Cost-effectively Meet Your Service Level Agreements
We include all of the essential cluster technologies you need for cluster-aware file system and volume management, so you can cost effectively meet your service level agreements.
Different businesses have different requirements for uptime. For some, it means making sure their data is backed up every week or every night, and readily available in case of an outage. For others, it means having 24 x 7 x 365 access to their mission critical applications. Whatever your availability requirements, SUSE Linux Enterprise High Availability Extension includes all of the essential clustering technologies to cost effectively meet your service level agreements with SUSE Linux Enterprise High Availability Extension.
SUSE Linux Enterprise High Availability Extension includes the latest version of OCFS2, which is now a shared-disk POSIX-compliant generic cluster file system. Using OCFS2, you can now cluster a much wider range of applications for higher availability using cluster-aware POSIX locking. You can also resize your clusters and add new nodes on the fly. Cluster-aware applications will also be able to make use of parallel I/O for higher performance.
SUSE Linux High Availability Extension includes an upgraded version of OCFS2, which offers improved performance with less file fragmentation and faster file operations. And support OCFS2 reflinks delivers improved cluster-wide snapshoting, enabling fast and efficient VM cloning and backups.
Also included in SUSE Linux Enterprise High Availability Extension is support for cLVM2, a clustered logical volume manager. cLVM2 provides you a single, cluster-wide view of storage. Clustering extensions to the standard LVM2 toolset allow you to use existing LVM2 commands to safely and simply manage shared storage.
