PSU Sizing: Connected Load, Efficiency Curves, and N+1 Redundancy
For N+1 redundancy in a dual-PSU server, both PSUs must be rated to handle full load alone. This is non-negotiable in production: if a single PSU fails and the surviving one is undersized, the system shuts down. The PD489 should be matched in wattage rating to the partner PSU in the chassis; mismatched ratings sometimes work but trigger warnings in the BMC.
AC Input, Phase Balancing, and Datacentre Power Best Practices
Document the PD489 model, wattage, and partner PSU in your CMDB. Power audits typically find one or two undersized servers and one or two over-redundant clusters per rack — both of which waste capacity that could feed additional production load.
