What power redundancy settings is most appropriate?
I am configuring an M1000E chassis for a High Performance Data Center. The configuration must allow for maximum efficient.
which option should I use?
Options:
Ο Power Supply Redundancy configuration without Dynamic Power Supply Engagement.
Ο Grid Redundancy configuration with Dynamic Power Supply Engagement
Ο No Redundancy configuration without Dynamic Power Supply Engagement
Ο No Redundancy configuration with Dynamic Power Supply Engagement

Hello.
Dynamic Power Supply Engagement offers high power efficiency by alternating powers supply between units between On and Off states. Depending on your power supply configuration, you may also need redundancy in event of either power grid failure or individual power supply failure. In non-clustered environment Grid Redundancy configuration with Dynamic Power Supply Engagement may be recommended. However, in typical clustered environment where multiple system chassis provide necessary redundancy; power redundancy is of little interest and No Redundancy configuration with Dynamic Power Supply Engagement is a better choice for maximum efficiency.
