NFS 3 vs. NFS 4.1
- [Narrator] In this video, I'll break down the differences between NFS version 3 and NFS version 4.1, and as of vSphere 6, NFS version 4.1 is now supported for our NFS data stores. So, NFS 4.1 comes with some additional functionality that version 3 does not include. That being said, there are also some limitations that are specific to NFS version 4.1 that you need to be aware of, as well. So, number one: With NFS version 3, storage traffic is strictly unencrypted. So, we can only use NFS on networks that we 100% trust. The other limiting factor is, as you can see here, there's only one IP address on our network-attached storage device. So, because of that, the ESXi host uses only one TCP connection for IO to the NFS storage device. Only a single IP address can be used for the NFS server for data store, and this can make load balancing difficult, because we typically use IP Hash for load balancing this type of traffic. If we have the same IP for all of our traffic, IP Hash isn't gonna…
