FlexCache primarily enhances what aspect of performance?

• A. Backup protection
• B. Write throughput for the origin
• C. Read performance and latency reduction for remote clients
• D. RAID reconstruction efficiency

Answer: (C)

FlexCache is all about speeding up read access for remote clients by bringing data closer to them. It places a local cache at the remote site that stores recently or frequently accessed data from the origin cluster. When a client requests data, if the item is already in the local cache, it’s served right there, delivering much lower latency and higher read throughput than going all the way to the origin. If the data isn’t cached yet, the cache fetches it from the origin, serves the client, and then keeps a copy for future requests, gradually building a hot local dataset. Writes, on the other hand, continue to go to the origin, so the immediate performance boost is focused on reads. This is especially beneficial for WAN-heavy environments or branch offices where read-heavy workloads repeatedly access common data.
