Possible to auto switch off/on

You can use the auto shutdown plugin. You can also take a look at this by jensk:

Here is an example of how to shutdown your machine autumatically every day at 6am in the power management serction of web-gui.

The auto power on is "sometime available in the BIOS" but never seen it on servers.

By concept servers are meant to be on 24/7. I would expect a Proliant server be "heavy" on your energy bill. Don't be surprised of HW issues after you power on/off a server on a daily basis fro long time. A similar analogy is the headers parking offered by the latest "green" HD, everybody suggest not to use them as it shortens the HD life in exchange of pennies on your energy bill.

Have you considered switching hardware to something smaller? OMV is not HW demanding at all.

Finally a PSU with efficiency 85%+ would help

HTH

I'd say the alternative is based on your storage requirements.
How much data do you have? How many data disks?

I run OMV into a smallish server tower where I have installed ESXi and mapped 4 data disks in total. I didn't have any choice at the time, nowadays I would just get a small desktop pc (like ex corporate or something) a USB stick for the OMV and 1x 4TB data disk. Unless you're doing much more than simple file sharing...

Zitat von "ryecoaaron"

Bad idea...

I thought that was suggested for OMV installations ?!

No one here, and not even volker, ever suggested to use a thunb stick or any kind of flash storage except a SSD to install OMV onto it.

Sorry I must have mixed up memories from nas4free/Freenas past experience.
For reference, what is the exact reason why this is not suggested?

Appreciated!

Ask the people who used a stick if it still works or how long it worked.

Get rid of the Idea or Debian/OMV gets rid of the stick for you.
