Power distribution on PSUs DL385 Gen10 Plus

Hello,

 

we have a couple of DL385 Gen10 PLus Server with HPC Profile and Max Cooling enabled. There are two Server with unusual power distribution across the internal PSUs. Is this normal?

For Example:

Server with unusual power distribution
HW PSU 0/1 OK - Chassis 0/Bay 1, State: "ok", Usage: 7 Watts
HW PSU 0/2 CRIT - Chassis 0/Bay 2, State: "ok", Usage: 500 Watts (warn/crit at 80/90)(!!)

Server with "normal" distrubution
OK HW PSU 0/1 OK - Chassis 0/Bay 1, State: "ok", Usage: 245 Watts
OK HW PSU 0/2 OK - Chassis 0/Bay 2, State: "ok", Usage: 243 Watts

Is this a normal behavior or should i open a Call?

Re: Power distribution on PSUs DL385 Gen10 Plus

Hello Pedae,

Thank you for posting your query.

As per the description, two servers have unusal Power distribution to Internal PSU's.

Could you please advise from where is this information captured? Are all these servers in your infrastructure connected to same Power Source?

Also please share the screenshots from iLO 5 GUI --> Power and Thermal 

a. Power Meter

b. Power

 

Please do check Integrated Management logs for any critical/Warning message? If any such alert is reported, please capture a screenshot?

 

Thank you

Hello,

the information is from SNMP readings. All other Servers are ok but only two show this values. Here are the Screenshots

Re: Power distribution on PSUs DL385 Gen10 Plus

These are the modes you can configure:

 

Balanced Mode—The system shares the power delivery equally between all installed power supplies.

High Efficiency Mode (Auto)—The system selects between the odd or even power supply based on a semirandomdistribution within a group of systems.

High Efficiency Mode (Odd Supply Standby)—The system places the odd power supply in standby.

High Efficiency Mode (Even Supply Standby)—The system places the even power supply in standby.


Hope this helps!
Regards
Torsten.

Re: Power distribution on PSUs DL385 Gen10 Plus

Hello Pedae,

Thank you for sharing the information.

From the screenshot both power supplies are working in Balanced Mode and the status of both PSUs is OK.

Do we notice any Critical/Warning messages in IML logs?

 

If yes,  I would suggest you to log a ticket with HPE Support Team for detailed analysis.

 

Thank you
