Power configuration
This page allows users to set the redundancy mode, and zero output mode for power conversion station configuration.
Minimum PCS Count: Click the pencil icon to edit and enter a minimum PCS count ranging from 1 to 4.
- Redundancy Mode: Offer three modes for users to choose from.
None: System could be throttled or shut down if one or more power supplies are in faulty condition.
N+1: There is one properly installed power supply as redundant power supply, so there is no impact to system operation or performance if any one of the power supplies is in faulty condition given that Oversubscription mode is not enabled.
N+N: N PCS active, and N PCS in standby mode.
- Oversubscription Mode: Grants users’ access to extra power from the redundant power supply. When the redundancy fails, however, the power supply will shut down within one second if system power loading is not corrected. SMM3 takes the action of node throttling at such power emergency, while enclosure performance could be impacted.
Oversubscription mode is applied with N+1 and N+N redundancy mode enabled.
When enabled with N+1 redundancy mode, the total available power will be equivalent to 1.2 times of the total capacity of the N+1 redundancy mode.
- Zero Output mode: Put PCS into sleep mode when power requirement is low.
The Zero Output mode is disabled by default and only applied with N+1 and N+N redundancy mode enabled.
Disabling Zero Output mode will keep all power supplies always active.
Three scanning period are offered: Disabled/10/30/60 minutes. Some PCS may enter hibernate mode to maintain the workload on the remaining active PCS at 50%, which makes the best efficiency out of PCS. When less time is chosen, SMM3 responds to workload changes more quickly
