• Power throttling
Each NovaScale Blade Server is powered by two NovaScale Blade Chassis unit redundant 2000
W power supply modules. By enforcing a power policy known as oversubscription, the
NovaScale Blade Chassis unit can load-share power between two power modules to ensure
efficient power for each device in the NovaScale Blade Chassis unit. This policy is enforced
when the initial power is applied to the NovaScale Blade Chassis unit or when a NovaScale
Blade Server is inserted into the NovaScale Blade Chassis unit.
The possible settings for this policy are:
— Redundant without performance impact
— Redundant with performance impact
— Non-redundant
You can configure and monitor the power environment using the management module. For more
information about configuring and using power throttling, refer to your management module
manual.
