When it comes to remote files access and sharing, the number one option most system administrators choose is Network File System (NFS). NFS is a distributed file system protocol that allows users accessing remote files and data over a shared network just if they were stored locally. As to VM storage management, and VMware vSphere particularly, NFS is much more convenient comparing to FC and iSCSI. This all leads the NFS protocol to be effectively used for simplifying IT infrastructure scalability and ensuring centralized data management since it provides simple and convenient access for multiple systems. Nevertheless, considering the configuration of traditional HA NFS File Server, certain challenges may arise.
