Virtual Machine File System – VMFS


Virtual Machine File System – VMFS

I was asked a question today and I thought it might be a good idea to begin posting the answers to some of the questions I am asked.

What is VMFS?

VMFS is Virtual Machine File System. It’s just the file system that exists on the VMWare ESX servers.
In it exists files one of which is vmdk, virtual machine disk.
The is the vm guest itself. Instead of the virtual machines having a hard drive they have a vmdk.
All of the vmdk’s are contained on a vmfs. Vmfs, ntfs, fat, fat32 these are all file systems.
