Shared Storage

The storage system provides an external common disk system accessible by all nodes of the cluster. The connection from the nodes to the disk sub-system is usually through a fiber switch or a SCSI connection. Once the storage volumes are presented to the hosts in the cluster, usually with the help of the logical volume manager, one can create volumes of suitable size for use in the RAC database. With the introduction of ASM methodology, the shared storage structures can be managed very easily. Once the disk groups are created with input of the disk devices, the ASM instances on each of the node in the cluster provide the shared storage resources to create the Database Files. We have discussed extensively about the preparation of storage structures in Chapter-5, "Preparing Shared Storage"

Public Network

The clustered servers or hosts need to have public network connectivity so that client machines in the network can access the resources on the RAC system.
