In maximum power conservation mode, all servers start functioning at their
minimum power levels, and all subsequent server power allocation requests
are denied. In this mode, the performance of powered on servers may be
degraded. Additional servers cannot be powered on, regardless of server
priority.
The system is restored to full performance when the user or an automated
command line script clears the maximum conservation mode.

Server Performance Over Power Redundancy
When enabled, this option favors server performance and server power up,
over maintaining power redundancy. When disabled, the system favors power
redundancy over server performance. When disabled, then if the power
supplies in the chassis do not provide sufficient power, both for redundancy,
as well as full performance, then in order to preserve redundancy, some servers
may not be:
