voltage regulator is single point of failure in E850C servers
You can refer to PMR 71797,820,820 (automatically created after call home) and relevant hardware ticket RCMS 01D5MG8,820. I'll focus on E850C (8408-44E) server, but maybe it's also relevant for other Power servers. Server has 4 power supplies and each of them is connected to a voltage regulator. Failure of only one of these 4 regulators causes server to go down, without possibility to power the server on until faulty regulator is replaced. Although there are 4 of them - each one is a single point of failure, which is unacceptable in enterprise-class server.
