Servers
IPMI console
Out-of-band access to a DediGPU server: the IPMI console, power control and virtual media, reached through the region jump host.
IPMI is the management controller on the server's board. It works when the operating system does not: you can watch the boot, get into the BIOS, power-cycle the machine and mount an ISO.
Reaching it
IPMI controllers sit on a management network that is not routed to the Internet. Each region has a jump host; the server page shows the IPMI address, user and password and the ready-made command:
ssh -l jump-rey -L 8443:10.90.12.34:443 jump.rey.dedigpu.cloud
# then open https://localhost:8443 in a browserThe jump host accepts the SSH keys of your account and nothing else. Its access is logged in your event log.
What you can do
- HTML5 KVM console: see the screen, type, from POST onwards.
- Power: off, on, reset, without asking us.
- Virtual media: mount an ISO from your computer and boot from it, for your own image or a rescue system.
- Sensors: temperatures, fans, power draw.
Do not change the BMC network settings or the BMC password. Both are managed; a change locks you out and the server is re-provisioned to fix it. Everything else on the controller is yours to use.
Simpler: reboot from the console
For a plain reboot, the server page's Reboot button does the same thing through IPMI, with a confirmation, and logs it.
