In this video, learn the differences between NFS 3 and NFS 4.1, and how these changes impact NFS datastores for vSphere 6.7. Also, learn how NFS 4.1 can secure storage traffic more effectively than NFS 3.
- [Instructor] 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, right? … So number one, with NFS version 3, … storage traffic is strictly unencrypted, right? … 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 I/O to the NFS storage device. … Only a single IP address can be used … for the NFS server per 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, …
