vSphere 6.0 is GA today, so re-blogging this with some added information!
DISCLAIMER: I work for NetApp. However, I don’t speak for NetApp. These are my own views. 🙂
I’m a tad late to the party here, as there have already been numerous blogs about what’s new in vSphere 6.0, etc. I haven’t seen anything regarding what was missing from a NFS perspective, however. So I’m going to attempt to fill that gap.
Famously, vSphere 6 brings us NFSv4.1. NFSV4.1 is an enhancement of NFSV4.0, which brought the following features:
- Pseudo/unified namespace
- TCP only
- Better security via domain ID string mapping, single firewall port and Kerberos integration
- Better locking than NFSv3 via a lease-based model
- Compound NFS calls (i.e., combining multiple NFS operations into a single packet)
- Better standardization of the protocol, leveraging IETF
- More granular ACLs (similar to Windows NTFS ACLs)
- NFS referrals
- NFS sessions
I cover NFSv4.x in some detail in TR-4067
