  6. Topics for discussion

    Power bars and BIOS settings.

    The "switched" power bars we use in the Forum and JCMB can be used in a slightly more sophisticated way than we do at the moment. The code to control them had the basic functionality done in order to allow remote control at all, but additional hooks to control things like turn-on delays and power-on state were never implemented. It would be useful to know what kinds of things people would like to be able to do.

    A possible solution was suggested as follows:

    Each outlet can have a randomised or numerical delay. Define a macro in a power bar header that would define 3 levels - immediate, middle and last. Randomise the power delay within each category when the power bar gets power back.

    The default BIOS power-on settings for servers probably leave the machines in the state they were in when the power went off. That may not be what's wanted, given that a machine might shut itself down in response to its UPS's status.

    An outstanding question - if a UPS is out, when the power comes back on, will anything come back or be able to be remotely powered on. Should BIOS setting be set to power on ?
