I think this article is correct, would like to confirm.
Cisco UCS 5108 Chassis Power Policy Options and Redundancy Demystify
https://icookservers.blog/2018/04/05/cisco-ucs-5108-chassis-power-policy-options-and-redundancy-demystify/
The article has a gist of:
N+1 is for a PSU failure.
GRID is for a PDU failure.
Are the PSU ON/OFF modes below correct?
GRID seems to be the way to go for 2 or 4 PDU's.
PDU Cabling would be like this:
PDU-A = PSU1
PDU-A = PSU2
PDU-B = PSU3
PDU-B = PSU4
GRID Mode with (Option 1)
PSU1/PSU2 to A
PSU3/PSU4 to B
If a PDU fails - You are saved!
PSU1 – A ON
PSU2 – A OFF (Power Saving Mode)
PSU3 – B ON
PSU4 – B OFF (Power Saving Mode)
Thanks in advance for any enlightenment on 5108 Chassis Power.
