Table 1-15. Configurable Power Budget/Redundancy Properties
Item Description
System Input Power Cap System Input Power Cap is the maximum input power
that the system is allowed to allocate to servers and chassis
infrastructure. It can be configured by the user to any value
that exceeds the minimum power needed for servers that
are powered on and the chassis infrastructure; configuring
a value that falls below the minimum power needed for
servers and the chassis infrastructure fails.
The power allocated to Servers and Chassis Infrastructure
can be found in the User Interface on the Chassis
Overview PowerPower Budget Status page under
Power Budgeting section or by using the CLI RACADM
utility command (
racadm getpbinfo).
Users can power off one or more server(s) to lower the
current power allocation, and re-attempt setting a lower
value for System Input Power Cap (if desired) or simply
configure the cap prior to powering on the servers.
To change this setting, it is possible to enter a value in any
of the units. The interface ensures that the unit field that
was last changed is the value that is submitted when those
changes are applied.
NOTE: For capacity planning, see the Datacenter Capacity
Planner (DCCP) tool at www.dell.com/calc.
NOTE: When value changes are specified in watts, the
submitted value exactly reflects the value that is applied.
However, when the changes are submitted in either of the
BTU/h or percent units, the submitted value may not exactly
reflect the value that is applied. This is because these units
are converted to watts and then applied; and the conversion
is susceptible to some rounding error.
