I've used nut for simple configurations before but now one has grown to a more complex setup and can't seem to find any info online.
I would like to have single central nut master monitor a bank of UPSs for a whole rack of servers with redundant PSUs. So UPS A1 ---> Server group A PSU 1 UPS A2 ---> Server group A PSU 2 UPS B1 ---> Server group B PSU 1 UPS B2 ---> Server group B PSU 2 I've read numerous pages about using MINSUPPLIES for redundant UPS->PSU setups, but nothing about setting up groups so that server bank B can stay up even if something happens to both UPS feeding server bank A. I've thought of a few possible solutions: 1. build a separate nut master for each group 2. use jails to make a lighter nut master instance for each group 3. run multiple instances of nut in the same server Is there something obvious that I am missing? Anyone done anything similar? Thank you for your time
