ESXi 7

Can you still run the OS and host the VM on the same partition (the OS installation and the VM machines)?  Told the client to buy separate disks for the new server Smiley Sadl.

Just to clarify that I understand the question correctly.

You are asking whether you can install ESXi on a disk/LUN and use the remaining disk space as a VMFS datastore? Yes that is perfectly fine. Just remember that a new ESXi 7.0 installation requires up to ~130GB disk space, compared to <10GB for earlier versions.

Edit: Changed "requires ~130GB disk space" to "requires up to ~130GB disk space" for clarification.

The disk usage depends on e.g. the installation media, its size, and whether it's a new installation, or an upgrade.

It's a recommendation and not an absolute minimum.

he wrote "require" and not "recommends" - you require as much storage as your workloads are using and the hypversior itself just takes 5 GB at a whole

Please keep your tone and language professional and courteous - as per this: VMware Community Code of Conduct

Regarding the ESXi 7 installation partitions, this is a good article: https://www.virtuallyghetto.com/2020/05/changing-the-default-size-of-the-esx-osdata-volume-in-esxi-7...

Sorry, but I can't take someone seriois coming up with "Oh I'm sorry, I'm having difficulty looking you up on the VCDX register" given that i seem more to know than VMwares own support for each and every issue in the past 10 years, they even come up with "install this driver for ESXi 6.0 on your ESXi 6.5" in case of network problems where the solution in fact was just swicth away from the native drivers (no longer supported in ESXi7)
