FlexCache software supports cache access for which types of clients?

FlexCache software is designed to improve the performance of data access by caching frequently requested files. It specifically supports clients that utilize the NFS (Network File System) and SMB (Server Message Block) protocols. NFSv3 is a widely used version of NFS, and it allows for effective reading and writing operations that can benefit from caching. Similarly, SMB is a protocol used for network file sharing that works particularly well in environments where Windows-based clients access shared files.

The combination of NFSv3 and SMB provides flexibility for various client systems to leverage the caching capabilities of FlexCache, enhancing the overall data access speed and efficiency. This capability is especially beneficial in mixed environments where different operating systems and client types need seamless access to the same data sets.

FlexCache's ability to serve both NFS and SMB clients allows organizations to optimize their data access patterns, making it easier to manage workloads that involve a variety of client types. The other options reference different versions of NFS or SMB that may not be specifically supported or may not align with the most common usage scenarios in a FlexCache deployment. Thus, the focus on NFSv3 and SMB in the correct choice accurately reflects the intended use of FlexCache in real-world applications.
