The clustering infrastructure now allows one resource per network name instead of one resource per share, which significantly improves resources' failover time. The failover process is faster for NFS version 3 clients because: NFS version 3 clients can have fast and transparent planned failovers with more availability and reduced downtime. The Port Multiplexing feature supports the RPC port multiplexer (port 2049), which is firewall-friendly and simplifies NFS deployment. Volume mount point lets you access volumes mounted under an NFS share with NFS version 4.1. NFS 2 SE WINDOWS
Identity Mapping Windows PowerShell module cmdlets make it easier to manage identity mapping, configure Active Directory Lightweight Directory Services (AD LDS), and set up UNIX and Linux passwd and flat files.New Kerberos privacy implementation and authentication options with the addition of Kerberos privacy (Krb5p) support along with the existing krb5 and krb5i authentication options.This completely removes the guesswork involved when tuning parameters, providing optimal performance as soon as NFS is deployed. Auto-tuned caches and thread pools are resource management capabilities of the new RPC/XDR infrastructure that are dynamic, automatically tuning caches and thread pools based on workload.
The RPC port multiplexer feature is firewall-friendly (less ports to manage) and simplifies deployment of NFS. This replaces Transport Device Interface (TDI), offers better support, and provides better scalability and Receive Side Scaling (RSS). The Remote Procedure Call (RPC)/External Data Representation (XDR) transport infrastructure, powered by the WinSock network protocol, is available for both Server for NFS and Client for NFS. Improvements to the overall NFS infrastructure in Windows Server 2012 are detailed below: Sessions and session trunking enables just one semantic and allows continuous availability and better performance while utilizing multiple networks between NFS 4.1 clients and the NFS Server. Compound RPCs combine relevant operations and reduce chattiness. An alias is provided for the exported file system, which is part of the pseudo file system. Pseudo file system, a file system that separates physical and logical namespace and is compatible with NFS version 3 and NFS version 2. NFS version 4.1 implements all of the required aspects, in addition to some of the optional aspects, of RFC 5661: Improves continuous availability on NFS version 3 clients.ĭeployment and manageability improvementsĮnables you to easily deploy and manage NFS with new Windows PowerShell cmdlets and a new WMI provider. Improves deployment and manageability, and increases security. Increased security, performance, and interoperability compared to NFS version 3. For information about functionality that is new or changed in Windows Server 2012, review the following table: Feature/functionality New and changed functionality in Network File System includes support for the NFS version 4.1 and improved deployment and manageability. Migrate applications from one operating system to another by storing the data on file shares accessible through both SMB and NFS protocols. Deploy a Windows NFS file server in a predominantly non-Windows operating system environment to provide non-Windows client computers access to NFS file shares. Use a Windows NFS file server to provide multi-protocol access to the same file share over both SMB and NFS protocols from multi-platform clients. Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019 Windows Server 2008, Windows Server 2008 R2 Windows supports multiple versions ofthe NFS client and server, depending on operating system version and family. Client for NFS allows a Windows-based computer running Windows Server to access files stored on a non-Windows NFS server. 
A computer running Windows Server can use Server for NFS to act as a NFS file server for other non-Windows client computers. NFS in Windows Server includes Server for NFS and Client for NFS. Using the NFS protocol, you can transfer files between computers running Windows and other non-Windows operating systems, such as Linux or UNIX.
Network File System (NFS) provides a file sharing solution for enterprises that have heterogeneous environments that include both Windows and non-Windows computers. This topic describes the Network File System role service and features included with the File and Storage Services server role in Windows Server. Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012
