E. Verify that the new controllers can be mixed with the existing systems in the cluster.
Explanation
When expanding an ONTAP cluster, it is essential to verify three key limits to ensure a smooth and successful expansion process:
- Cluster Limits: Before adding new nodes, verify that the expanded cluster will not exceed the maximum supported number of nodes, aggregates, volumes, LUNs, and other cluster-wide resources. Exceeding these limits can lead to performance issues and instability.
- SAN Limits: If your cluster provides SAN services, check that the expanded cluster will not surpass the supported limits for LUNs, igroups, initiators, and other SAN components. Overstepping these boundaries can impact SAN performance and reliability.
- Controller Compatibility: Confirm that the new controllers are compatible with the existing systems in the cluster. Mixing incompatible controllers can result in communication issues, feature disparities, and performance problems. Consult the ONTAP documentation and interoperability matrix to ensure the new controllers are supported for mixed-cluster configurations.
While verifying the maximum RAW cluster capacity and NAS limits are important considerations for overall cluster health, they are not among the top three limits to check specifically when expanding an ONTAP cluster.
By thoroughly verifying these three critical limits before proceeding with the expansion, you can minimize the risk of encountering issues and ensure a successful, stable, and performant expanded ONTAP cluster.
