Ok, this is serious. The client has had an HPE ProLiant ML110 Gen11 Server in production for more or less a year, purchased new. As usual in their setup, we installed Proxmox (8.1, available at the time of installation) right from the start.
They need to standardize, and since some internal employees need to manage the VMs, Proxmox has been the ideal choice for the last 11 years.
Everything was fine, the server was in production for months without any issues. Suddenly, about a month and a half ago, they realize that the fan is always running at maximum speed. They move the workloads to another server, no difference. Now that it's idle, they try to restart it, but it doesn't change. They try booting with a System Rescue CD - the fans are still at maximum. We update Proxmox, no difference. They open it up to check, the fans are clean.
We contact HP support, they ask for the operating system - I send Proxmox, the Proxmox version, and the kernel version. I’m attaching just the latest response:
"Dear customer,
I’m sharing with you the matrices of operating systems managed by HPE and which may have different compatibility depending on the models:
HPE Servers Support & Certification Matrices
https://www.hpe.com/us/en/collaterals/collateral.a50010841enw.html
Proxmox 8 is not among those operating systems that are certified for firmware on HPE servers.
I asked you to inform yourself about the OS and kernel version because the kernel source codes refer to particular versions of Redhat, so it might fall under compatibility, and therefore it would make sense to install this operating system on your server model."
Proxmox isn't "certified". Debian isn't "certified".
Needless to say, the fiery response was sent. If they don't manage the issue... well, we’ll wait. Stay tuned!
