Cache hits and misses indicate if the data requested by the client is served directly from the FlexCache volume or from the origin volume. The occurrence of a cache hit or miss depends on factors such as availability of the requested data in the cache, the attribute cache timeout values, and the difference between attributes of a file in the cache and the origin.
When a client sends a read request, if the relevant block is cached in the FlexCache volume, the data is read directly from the FlexCache volume. This is called a cache hit. Cache hits are the result of a previous request.
If the requested data is not on the FlexCache volume, or if the data has changed since it was cached, the caching system loads the data from the origin volume, and then returns it to the requesting client. This is called a cache miss.
