  • The only reason that I have measured my server is that it has that feature built into the iDRAC. I have been thinking of buying an external power meter for years but have never bothered to do that.

    Luckily I got my server for free from work. It was part of an old SAN so it came with 4 dual 16 Gbit fiber channel cards and 2 dual 10 gigabit ethernet cards. Before I took those out of the server it consumed around 150 watts at idle which is crazy.


  • Yeah server hardware isn’t the most efficient if you want to save power. It’s probably better to get a NUC or something.

    With that said my old Dell PowerEdge R730 only uses around 84 watt (running around 5 VMs that are doing pretty much nothing) The server runs Proxmox and has 128 GB of ram, two Xeon E5-2667 v4 CPUs, 4 old used 1 TB HDDs I bought for cheap, and 4 old used 128 GB SATA SSDs I also bought for cheap (all storage is 2,5 drives).

    All I had to do was change a few BIOS settings to prioritize efficiency over performance. 84 watts is obviously still not great but it’s not that bad.




  • The reason that most companies don’t want you to do that is because they don’t want people running around installing their own OS and doing whatever they feel like on company devices.

    Letting people do that would be an IT and information security nightmare.

    It’s the same reason that no (sane) company would give local admin privileges to everyone.

    The reason why companies generally don’t have an official way to use Linux is because it’s hard to support two platforms simultaneously. Especially when you have, certificate and/or AD network authentication for wireless and wired like we do. You also need to consider how the two platforms should interact with each other. For example Linux devices should be able to connect to the AD domain with Kerberos and need to be able to access SMB shares and probably other systems.

    In short it’s more complicated than “just let me try”.


  • I am a Windows admin but two of my colleagues who are Linux admins use Linux machines that are running Ubuntu+a few internal tweaks to make it better fit us. The Linux platform is developed primarily by one of the developers at the company and some others (primarily developers) also use Linux. The vast majority of the company uses Windows.

    There are also a few hundred Macs.

    I have been considering getting our flavour of Linux installed on a VM or maybe even dual booting for testing.
