Oracle Database Tips by Donald Burleson

Oracle10g Grid Computing with RAC
Chapter 5 - Preparing Shared Storage

PolyServe Matrix Server (MxS)

MxS is a general-purpose cluster file system that runs on a Linux or Windows cluster. It is used for Oracle RAC and other HA solutions. MxS supports all Oracle data files and redo logs. It further supports advanced Oracle functionality including external tables, export/import from text files, and archived redo log compression. MxS also supports a shared Oracle Home, which simplifies installation, configuration, and maintenance.

Other CFS solutions:

Network Appliance Filers offers CFS-like functionality via NFS to the server machines. These file systems are mounted using special mount options.

IBM's General Parallel File System (GPFS) allows users shared access to files that may span multiple disk drives on multiple nodes. GPFS provides access to all data from all nodes of the cluster. GPFS is only supported with HACMP/ES in a RAC configuration.
