What is the primary function of a FlexCache Volume?

The primary function of a FlexCache Volume is to generate writable volume replicas by caching data from a FlexVol Volume or from a shared file system. FlexCache operates by providing a method to increase read performance and improve efficiency for frequently accessed data across different locations. It acts as a read-write cache that allows users to make modifications to data while also ensuring that the original data is not directly altered. This mechanism is particularly useful in scenarios where multiple clients require rapid access to the same datasets, improving latency and resource usage.

FlexCache enables seamless access to the cached data and allows the written data to be transferred back to the originating volume, making it an effective solution for environments with distributed workloads and high-read demands. Its design focuses on optimizing performance and accessibility while minimizing the load on the primary storage systems.
