Marketing description

The Resilient Storage Add-On for Red Hat Enterprise Linux provides numerous file system capabilities for improving resiliency to system failure.

Key selling points

• GFS2 shared storage file system
• Cluster Logical Volume Manager (CLVM)
• Clustered Samba

Product features

• GFS2 shared storage file system
  GFS2 is a clustered file system in which data is shared among GFS2 nodes with a single, consistent, and coherent view of the file system name space. Processes on different nodes may work with GFS2 files in the same way that processes on 1 node can share files in a local file system.
• Cluster Logical Volume Manager (CLVM)
  CLVM provides certain Logical Volume Manager, version 2 (LVM2) features cluster-wide while retaining all the existing LVM2 features for single-node operation. The logical volumes created with CLVM make logical volumes available to all nodes in a cluster.
• Clustered Samba
  Clustered Samba enables exporting of a GFS2 file system through 1 or more nodes in the cluster in an active/passive or active/active configuration to provide a highly available Samba service. This technology, currently in tech preview, will allow Red Hat Enterprise Linux servers to provide robust storage for Microsoft clients.
