Benefits and Applications
The following sections describe CFS benefits and some applications.
Advantages To Using CFS
CFS simplifies or eliminates system administration tasks resulting from hardware limitations:
•The CFS single file system image administrative model simplifies administration by allowing all file system management operations, resizing, and reorganization (defragmentation) to be performed from any node.
•You can create and manage
•Keeping data consistent across multiple servers is automatic, because all servers in a CFS cluster have access to
•Applications can be allocated to different servers to balance the load or to meet other operational requirements, because all files can be accessed by all servers. Similarly, failover becomes more flexible, because it is not constrained by data accessibility.
•The file system recovery portion of failover time in an
•Enterprise storage arrays are more effective, because all of the storage capacity can be accessed by all nodes in the cluster, but it can be managed from one source.
•Larger volumes with wider striping improve application I/O load balancing. Not only is the I/O load of each server spread across storage resources, but with CFS shared file systems, the loads of all servers are balanced against each other.
•Extending clusters by adding servers is easier because each new server’s storage configuration does not need to be set up - new servers simply adopt the
•For the following HP Serviceguard Storage Management Suite CFS for Oracle bundles, the clusterized Oracle Disk Manager (ODM) feature is available to applications running in a cluster, enabling
