Enabling Memory Tiering in VCF/vSphere 9.1 through the CLI!

Duncan Epping · Jun 16, 2026 · Leave a Comment

I saw a question internally this week about enabling Memory Tiering through the CLI with 9.1 and why that didn’t work as you would expect. I wrote an article about the esxcli commands a while back, so I went through them and then I realized indeed that the article was outdated. I participated in a few early access programs and one of the things we had to do was enable memory tiering using the new esxcli namespace. Where in the past there were  various advanced settings you had to configure, and various commands to run, they now made things much easier. Just some examples below.

The new name space:

esxcli memtier

Enable memory tiering using a particular device:

esxcli memtier enable -d <device_name>

Enable memory tiering using a particular device and with a 400% ratio percentage, this value can be between 1 and 400:

esxcli memtier enable -d <device_name> -r 400%

Enable encryption after memory tiering has been configured:

esxcli memtier config set --encryption true

You can find the full documentation here and here.
