2.2 General Server Requirements

Verify that servers where you install Oracle Grid Infrastructure meet the minimum requirements for installation.

• Select servers with the same instruction set architecture as cluster members.

• Ensure servers run the same operating system binary.

• Oracle Grid Infrastructure installations and Oracle Real Application Clusters (Oracle RAC) support servers with different hardware in the same cluster. Your cluster can have nodes with CPUs of different speeds or sizes, but Oracle recommends that you use nodes with the same hardware configuration.

  Oracle recommends that if you configure clusters using different configuration, that you categorize cluster nodes into homogenous pools as part of your server categorization management policy.
