A customer has a small office location that needs fast local read access to their...

The SGF6112 is specifically suited to this requirement because StorageGRID supports configuring this appliance to operate as a Gateway Node with caching. NetApp documents the SGF6112 as a compact 1U all-flash appliance containing 12 NVMe SSDs, and explicitly lists its ability to operate as a Gateway Node with caching. This enables frequently accessed S3 objects to be cached close to the application without deploying a complete StorageGRID site containing multiple Storage Nodes.

This architecture is particularly appropriate for a small office with restricted rack space and power. The caching Gateway serves repeatedly accessed objects locally, reducing retrieval latency and WAN traffic while the authoritative object data continues to reside on the existing StorageGRID Storage Nodes.

Options A and C create entirely new StorageGRID sites. A production site requires at least three Storage Nodes, which significantly increases equipment, power, cooling, and rack requirements. C additionally deploys multiple high-performance appliances when only local read acceleration is required.

Option B is invalid because the SG5812 is a Storage Node appliance and does not provide the SGF6112's supported caching-Gateway operating mode.

Therefore, D provides the required local-read performance with the smallest practical physical footprint.
