3、 requirements have gone mainstream.The world is moving to software-defined on commodity infrastructure.Linux is ubiquitous enables a sophisticated,standards-based,open-source client to come built-in(not third-party).Therefore:NFS 4.2 solves these problems.File access that bridges storage silos,sites
