In a Nutshell
This chapter introduced the various building blocks of Oracle RAC. Oracle Grid Infrastructure provides the foundation for Oracle RAC scalability and availability. Because storage is shared across all the nodes, it is very important to establish redundancy at the disk level, and the RAID technologies help to build a very scalable and highly available storage subsystem.
Next, the storage the network components play a vital role in building the cluster. We also looked into the different options available for storage and interconnects, which are key to the systems in supporting scalability and availability. Bonded network interfaces at the operating system level provide the redundancy and required scalability for cluster operations. ...
