The hardware architecture for Oracle RAC is designed to provide high availability and scalability. Key components include:
- Server Nodes: Each server node runs an instance of the database, and all nodes share access to a single database using the shared SCAN (Shared Server Connection) or dedicated servers (DSC).
- Storage: Shared storage is used for data files and redo logs. It can be a SAN (Storage Area Network), NAS (Network Attached Storage), or DAS (Direct Attached Storage).
- Interconnect Network: This network connects all the server nodes in the cluster and provides high-speed communication between them.
