Endorsed by Cray, Digital Equipment Corp, IBM, HaL Computer Systems, Hewlett-Packard Company, and Sun Microsystems Inc., NFS Version 3 is the latest revision of the industry-standard file system, NFS. In addition, Digital, HaL, and IBM successfully tested their NFS Version 3 implementations for interoperability at the Connectathon `93 Testing Event in San Jose, Calif. last week. NFS Version 3 evolved from the industry-standard NFS protocol and is based on requirements specified by computer industry leaders such as Cray, Data General, Digital, IBM, HP, HaL, Open Software Foundation (OSF), SunSelect and SunSoft. The NFS distributed file service is a key component of SunSoft's ONC` networking technology. With an installed base of over 4 million seats, the technology has been licensed by more than 100 companies including Novell, IBM, HP, SCO, and Digital and is the standard for transparent remote and local filesharing between heterogeneous systems. NFS Version 3, a standard component of SunSoft's ONC+ networking technologies, takes these capabilities further to provide improved scalability and performance and support for high bandwidth networks, critical for emerging interactive applications based upon technologies such as FDDI, 100 Megabit Ethernet and Asynchronous Transfer Mode (ATM). "Networking is the cornerstone of true distributed computing" said Steve Bourne, director of networking technology for SunSoft. "With NFS Version 3, network file systems can evolve to meet the growing demands of full scale interoperability in the enterprise-wide computing arena." "New applications such as multimedia and imaging are driving the availability of high-bandwidth networking and the need for standard network services which take advantage of the power of that bandwidth," said Randall R. Meals, general manager of Hewlett-Packard's information networks division. "We see NFS Version 3 as a significant development, providing a robust network service which optimizes the performance available in the underlying network." "Digital has been pleased to work closely with Sun since the inception of NFS to build a distributed file system that has been accepted as an industry standard," said William Demmer, vice president, computer systems group, at Digital. "We are especially happy to be contributing to NFS Version 3 because of the increased performance it brings to users and the 64-bit support that complements our Alpha AXP strategy." NFS Version 3 provides wide-area network efficiency, multiplatform interoperability, improved security, scalability and performance. Specific enhancements to NFS included in Version 3 are: - Improved performance: NFS Version 3 supports asynchronous writes so the client does not have to wait for an NFS server to write file data to the disk. - Increased server scalability: NFS Version 3 reduces server load by returning file attributes on every call rather than requiring specific queries. As a result, the server receives fewer client requests, decreasing server load and increasing scalability. - High bandwidth network support: The read or write request limitation of 8 kilobytes has been removed, allowing the client and server to negotiate a transfer size based on the available network bandwidth. This offers a tremendous advantage when using NFS over high bandwidth networking technologies such as FDDI, ATM, or 100 Megabit Ethernet. - Improved security: NFS Version 3 improves client file access permissions by adding checking capabilities at the server. Clients can determine acceptable file operations prior to actually attempting access. - Support for large files: 64-bit file sizes and offsets are supported by NFS Version 3 allowing multi-gigabyte file systems to be accessed on NFS servers, and providing support for future 64-bit-based systems. Availability The NFS Version 3 specification is available immediately free of charge, via the Internet Server at "ftp.uu.net", "gatekeeper.dec.com" or "bcm.tmc.edu." Implementations of NFS Version 3 will be generally available in 1994.

The specification of this new version has been developed with the cooperation of several vendors active in the NFS community. Several implementations based on this specification will be tested at this year's Connectathon in San Jose. Availability of implementations of this new version will be discussed at a later time. A specification describing the new protocol is available via anonymous ftp from: ftp.uu.net:/networking/ip/nfs/NFS3.spec.ps.Z bcm.tmc.edu:/nfs/nfsv3.ps.Z gatekeeper.dec.com:/pub/standards/nfs/nfsv3.ps.Z The specification is available as a compressed postscript file. NOTE: this specification supercedes any previous version of an NFS Version 3 specification that you might have in your possession. This version of the NFS protocol features 64 bit support, exclusive create, ACCESS over the wire, and support for asynchronous writes. In addition, the protocol includes support for increased performance which is attributable to an improved client caching model, relaxed transfer size restrictions, and a reduction in the number of GETATTR operations that a client must make. All of the field overloads which existed in Version 2 implementations have been replaced with direct support in the new protocol. Also included are new versions of the MOUNT and NLM protocols. The new MOUNT protocol contains support for returning NFS Version 3 file handles as well as returning RPC authentication flavors supported by the server. The new NLM protocol includes 64 bit support and improved error handling. Questions and/or comments should be directed to nfs3@eng.sun.com. Thanx...
