There's a case with blades/chassis with 4 power supply, where:
2 out of 4 servers use 2 power supply and the other 2 servers use the 2 others power supply

In case of blade, we'll need to create the power supply on the parent device and get_or_create

It's a 4u box, with 4 power supplies in it; there are 8 blades, 4 nodes/blades (n1,n2,n3,n4) use two of the power supplies, the other 4 nodes (n5,n6,n7,n8) use the other two power supplies.

from lshw -json (which is way better than dmidecode - it includes the sata and nvme drives)

    {
      "id" : "power:0",
      "class" : "power",
      "description" : "PWS-1K62P-1R",

      "serial" : "P1K65CF11CT1837",
      "units" : "mWh",
      "capacity" : 1620
    },
    {
      "id" : "power:1",

      "serial" : "P1K65CF11CT1838",
      "units" : "mWh",
      "capacity" : 1620
    },

from another node, on the other 2 power supplies:

    {
      "id" : "power:0",
      "class" : "power",
      "description" : "PWS-1K62P-1R",
      "product" : "PWS-1K62P-1R",
      "vendor" : "SUPERMICRO",
      "physid" : "1",
      "version" : "1.3",
      "serial" : "P1K65CF11CT1839",
      "units" : "mWh",
      "capacity" : 1620
    },
    {
      "id" : "power:1",
      "class" : "power",
      "description" : "PWS-1K62P-1R",

      "units" : "mWh",
      "capacity" : 1620
    },

What's interesting is the BMC Webinterface has a multinode page, that shows 4 of the nodes..

Now to see if I can get that via Redfish, or scrape the page (ugh)

Unfortunately it seems that dmidecode gives more infos for power supply like:

  • Hot swap
  • Pluggued or not

I think we'll go for dmidecode output, or let the user chose lshw if needed

We can also report the PSU consumption:

Power Consumption Information

Power Consumption
Index             : 2
Status            : Ok
Probe Name        : System Board Pwr Consumption
Reading           : 735 W
Warning Threshold : 1911 W
Failure Threshold : 2100 W

Amperage
PS1 Current 1 : 1.8 A
PS2 Current 2 : 1.4 A

For example, omreport doesn't report the power consumption per PSU in W
But it gives the Amperage per PSU

If the user has setup the Power Feed for the datacenter of the server, we can report the PSU consumption via PS1 Amperage * Power Feed Voltage

We could add a get_power_consumption method per Manufacturer then

We can also report the PSU consumption: ``` Power Consumption Information Power Consumption Index : 2 Status : Ok Probe Name : System Board Pwr Consumption Reading : 735 W Warning Threshold : 1911 W Failure Threshold : 2100 W Amperage PS1 Current 1 : 1.8 A PS2 Current 2 : 1.4 A ``` For example, `omreport` doesn't report the power consumption per PSU in W But it gives the Amperage per PSU If the user has setup the `Power Feed` for the datacenter of the server, we can report the PSU consumption via `PS1 Amperage * Power Feed Voltage` We could add a `get_power_consumption` method per Manufacturer then
