In this video, Kevin Dankwardt discusses distributed file systems. He describes OpenAFS and GlusterFS. He demonstrates the packages and utilities involved in GlusterFS on CentOS 7.
- [Voiceover] Let's talk for a couple of minutes…about distributed file systems.…That is where the file system is spread around…among multiple servers,…but gives the appearance of a single file system to clients,…unlike NFS, where you're just getting your file system…from a single server.…So, with distributed file systems and redundancy,…you can perhaps have better resiliency…and improved performance, and scalability.…So, there's a few examples.…One that's been around for a while is called OpenAFS.…
That's from the Andrew File System,…work that's been done for many years now.…And it's evolved, and it's got some nice features…like local disk caching, to improve performance.…And one of the things that distinguishes it…is the way that you reference the system,…is not just for a particular server, so you can…say, have a server go down,…and you don't have to reconfigure all the clients.…
And it can improve performance by replicating data,…if it's read-only, so you can spread copies of it around,…to perhaps, a closer server, for better performance.…
