Deploying Oracle Real Application Clusters on Sun Storage 7000 Unified Storage System
Source: Sun Microsystems
The Sun Storage 7000 Unified Storage System supports NFS v3, NFS v4, iSCSI, and CIFS protocols and comes with a comprehensive set of data service features which provide unlimited snapshots, clones, and remote replication. Oracle Real Application Clusters (Oracle RAC), a clustered database infrastructure, offers highly scalable architecture and allows accessing the same database files from a shared storage. It uses Oracle Clusterware software that enables the RAC nodes to communicate with each other. Oracle Clusterware runs the Cluster Ready Services (CRS). CRS has two components. One is the Oracle Cluster Registry (OCR) which stores and maintains the cluster and node membership information. The other is the Voting disk which monitors the state of the nodes.
