To expand capacity for a 4-node AFF A400 cluster with NS224 shelves, which actions would enable this?

• A. Deploy a new AFF A400 to the cluster.
• B. Deploy new dedicated storage switches for the new NS224 shelves.
• C. Both Deploy a new AFF A400 to the cluster and Deploy new dedicated storage switches for the new NS224 shelves.
• D. None of these

Answer: (C)

Expanding capacity in an AFF cluster with expansion shelves requires both more controller resources and proper storage network connectivity. The NS224 expansion shelves need a path into the cluster’s data plane, which is provided by storage switches, so the new shelves can actually be addressed and used. At the same time, adding a new AFF A400 increases the cluster’s compute and memory capacity, allowing the data to be balanced across the larger pool and preventing any single controller from becoming a bottleneck. Without the new controller, the shelves would have nowhere to be served from; without dedicated storage switches, the shelves wouldn’t have a reliable, scalable fabric to support its traffic. Therefore, deploying both a new AFF A400 to the cluster and dedicated storage switches for the new NS224 shelves enables true expansion of capacity and performance.
