VAST Cluster supports the NFSv3 file sharing protocol, enabling storage clients to access files and directories using NFSv3.
From VAST Cluster 1.2.2, VAST Cluster supports NFS over Remote Direct Memory Access (NFSoRDMA), enabling you to run NFS with high speed over an RDMA capable network. For help enabling RDMA on NFS client hosts, see Configuring Linux Server Machines as NFSoRDMA Clients.
The NFS file system is dividable into directories which you can expose to clients via exports. NFS clients can mount and access the exports as if accessing local file storage. Using export policies, you can control which hosts can access which exports.
Depending on configuration per export and per client user, access to files is either authorized through your directory server or based on authentication parameters supplied in remote procedure calls (RPCs). See Managing NFS File Access_U for details.
The VAST Cluster NFSv3 server supports NLM file locking, a protocol that implements advisory byte range file locking to ensure data consistency.
