For as long as I can remember it has not been uncommon for I.T “professionals” working in the storage industry or in a storage role to make statements about NFS (Network File System) as if its is a 2nd class citizen in the storage world.
I’ve heard any number of statements such as:
- NFS is slow(er) than block storage
- NFS (datastores) don’t honour all SCSI commands
- NFS is not scalable
- NFS uses significantly more CPU than block storage
- NFS does not support <insert your favourite technology here>
People making these statements are known as “Block Dinosaurs”
The definition of “Block Dinosaur” is as follows:
- homo sapien becoming less common in the wild since the widespread use of NFS with vSphere and Hyper-Converged solutions
- a species soon to be attempts to spread Fear Uncertainty and Doubt (FUD) about the capabilities of NFS storage
- inflexible and requires an outdated technologies such as “LUNs” , “Zoning” & “Masking”.
- a person who does not understand SCSI protocol emulation and/or has performed little/no practical testing of NFS storage in which to have an informed opinion;
- a person who drinks from the fire hose of their respective employer or predominately block storage vendor;
