What is FlexCache and when would you use it?

• A. FlexCache enables caching of data on a remote or secondary node to improve read performance for bottlenecked workloads
• B. FlexCache provides automatic data deduplication across volumes
• C. FlexCache is used to back up data to cloud storage
• D. FlexCache compresses data on write to save space

Answer: (A)

FlexCache is a caching layer that speeds up reads by storing frequently accessed data from a remote or secondary source on a local cache. When clients ask for data, the system serves it from the cache if it’s there; if not, the data is fetched from the origin and then cached for future requests. This reduces read latency and lowers network traffic to the remote site, which is especially helpful when workloads are bottlenecked by distance or network access to the primary storage. You’d use FlexCache when you have many clients at a remote site or over a WAN and want better read performance for data located on another cluster or volume. Writes typically continue to go to the origin, ensuring consistency, while the cache serves subsequent reads quickly. It’s not a deduplication feature, a means to back up data to cloud storage, or a compression tool.
