Is NFS scalable?

The NFS^2 architecture allows standard NFS servers to be combined into a single, scalable file system. Each NFS server is essentially treated as an object store.

Does NFS scale?

The NFS device inherently sits directly in the data path, and can’t scale performance to accommodate the demands of I/O intensive computing or multiple concurrent requests.

Does anyone use NFS anymore?

The most common NFS in use today, NFSv3, is 18 years old — and it’s still widely used the world over. … Sure, there are still millions of Unix boxes using NFS, but now there are also millions of virtualized Windows servers that are running from NFS storage through the hypervisor.

Is NFS centralized?

NFS provides a central management. NFS allows for a user to log into any server and have access to their files transparently. … No manual refresh needed for new files. Can be secured with firewalls and Kerberos.

Why is NFS bad?

The reason is the NFS write cache, which usually does not get flushed until the file is closed. … So when a client removes a file, it will be gone for good, and the file handle is no longer valid – and and attempt to read from or write to that file will result in a “Stale file handle” error.

Which is better SMB or NFS?

Conclusion. As you can see NFS offers a better performance and is unbeatable if the files are medium sized or small. If the files are large enough the timings of both methods get closer to each other. Linux and Mac OS owners should use NFS instead of SMB.

Why NFS is used?

NFS, or Network File System, was designed in 1984 by Sun Microsystems. This distributed file system protocol allows a user on a client computer to access files over a network in the same way they would access a local storage file. Because it is an open standard, anyone can implement the protocol.

Is NFS a security risk?

NFS like any other unprotected network protocol is vulnerable to two types of attacks: eavesdropping and impostor attack. An eavesdropper can pick up unauthorized data as it goes by on the network. An impostor can gain an unauthorized access to the network.

What can I use instead of NFS?

Alternatives to NFS include AFS, DFS and RFS.

  • AFS – Andrew File System. AFS is a distributed file system that enables co-operating hosts (clients and servers) to efficiently share file system resources across both local area and wide area networks. …
  • DFS – Distributed File System. …
  • RFS – Remote File Sharing.

How does NFS authenticate?

NFS V4 normally authenticates clients at the user level rather than at the host level. The two user authentication methods are auth_sys (UNIX authentication) and RPCSEC_GSS (Kerberos). Under the auth_sys security method, the user is authenticated at the client, usually through a logon name and password.

Does NFS use UDP?

All versions of NFS can use Transmission Control Protocol (TCP) running over an IP network, with NFSv4 requiring it. NFSv2 and NFSv3 can use the User Datagram Protocol (UDP) running over an IP network to provide a stateless network connection between the client and server.

Is NFS fast enough?

The short answer is use NFS. According to this shootout and my own experience, it’s faster. But, you’ve got more options! You should consider a cluster FS like GFS, which is a filesystem multiple computers can access at once.
