- The Hardware Architecture of the Oracle RAC clusters provides a shared architecture with the server pools and allows all the storage devices to be shared.

- Hardware Architecture supports different types of storage networks like Network attached storage (NAS), Storage Area Network (SAN) and SCSI disks.

- Hardware architecture is such that it provides appropriate choices for the storage pools and system that provides scalability and flexibility to the overall system.

- The architecture should contain the input and output for the application that need to be developed and then the system can have more scalability.

- Hardware architecture supports more application to be added in the server pool and allows better integration of services.
