AI Infrastructure Operations and Troubleshooting

A customer deploys a UCS 885a server in a data center with two power grids. Three of the server’s 3000W power supplies are connected to each grid. Because of an external event, one grid will be shut down for maintenance. How does the server react to this event?

Explanation

UCS C885A M8 54V power uses 4+2 PSU redundancy and does not support full grid redundancy. Loss of one grid leaves three 54V AC PSUs; in that condition, the server continues operating with reduced performance and applies a 60% power cap to every GPU.
