Power Supply Redundancy Configuration
IThis functionality is not available with all servers.
The Power Supply Redundancy Configuration group allows you to set the
redundancy mode for the managed server. It depends on the servers
capabilities which options are actually available.
PSU Redundancy 1 + 1 Spare PSU
System operation is guaranteed for 1 PSU fail in the case of 2 PSUs in
total.
PSU Redundancy 2+ 1 Spare PSU
System operation is guaranteed for 1 PSU fail in the case of 3 PSUs in
total.
PSU Redundancy 3+ 1 Spare PSU
System operation is guaranteed for 1 PSU fail in the case of 4 PSUs in
total.
AC Redundancy 2 + 2 (2 AC sources)
2 of the 4 PSUs are each connected to a separate AC source. This
ensures that the system can continue operation even if a power line or a
single PSU fails.
AC Redundancy 1 + 1 (2 AC sources)
Each PSU (of 2 PSUs in total) is connected to a separate AC source. This
ensures that the system can continue operation even if a power line or a
single PSU fails.
