VMware with Dell VxRail Support: UPS without Outlet Groups
Example 1a: Standard Cluster. Turn off the UPS enabled, no shutdown
command file or SSH action configured, PowerChute deployed as a VM.
PowerChute is deployed as a VM inside the Cluster, configured for a
Single/Redundant UPS configuration. The option to Turn off the UPS is
enabled on the Shutdown Settings page. No shutdown command file or SSH
action configured. The durations in this example are as follows:
- VM and vApp Shutdown Duration = 120 seconds
- Cluster Shutdown Delay = 60 seconds
- Cluster Shutdown Duration = 180 seconds
When a critical UPS event, such as On Battery occurs, the following
sequence is triggered.

- PowerChute reports
that the UPS is on battery.
- After the shutdown
delay configured for the On Battery event has elapsed, PowerChute
issues a command to turn off the UPS. UPS turnoff starts.
- PowerChute starts
to shut down User VMs and vApps.
- After 2 minutes
(VM/vApp Shutdown Delay), PowerChute sends a request to the Network
Management Card to shut down the cluster using the VxRail REST API.
- PowerChute then
starts a local OS shutdown to power itself off. All user VMs must
be powered off before cluster shutdown can proceed.
- After 60 seconds
(Cluster Shutdown Delay), the NMC issues the VxRail cluster API shutdown
command. At this point, all user VMs including the PowerChute VM should
be off.
- After 180 seconds
(Cluster Shutdown Duration), the cluster and ESXi hosts are shut down
and the UPS will turn off shortly after this.
- The UPS will wait
the amount of time indicated by one of the following, whichever is
greater:
Low Battery Duration or Maximum
Required Delay
These are shown on the Configuration - Shutdown page in the NMC interface.
- After this delay, a further non-configurable
two minute delay is counted down.
- The UPS will then turn off after the
user-configurable Shutdown Delay time
has elapsed.
This is configurable on the Configuration - Shutdown page in the NMC
user interface.
It is recommended that the Low Battery Duration
is configured to allow enough time for the Operating System shutdown to
complete.
Example 1b: Stretched Cluster. Turn off the UPS enabled, no shutdown
command file or SSH action configured, PowerChute deployed as a VM.
PowerChute is deployed as a VM on the Management host outside the Cluster,
configured for a Single/Redundant UPS configuration. The option to Turn
off the UPS is enabled on the Shutdown Settings page. vCenter Server is
deployed as a VM on the Management Host outside the Cluster. No shutdown
command file or SSH action configured. The durations in this example are
as follows:
- VM and vApp Shutdown Duration = 120 seconds
- Cluster Shutdown Delay = 0 seconds
- Cluster Shutdown Duration = 180 seconds
- vCenter Server Appliance Shutdown Duration = 240 seconds
When a critical UPS event, such as On Battery occurs, the following
sequence is triggered.

- PowerChute reports
that the UPS is on battery.
- After the shutdown
delay configured for the On Battery event has elapsed, PowerChute
issues a command to turn off the UPS. UPS turnoff starts.
- PowerChute starts
to shut down User VMs and vApps.
- After 2 minutes
(VM/vApp Shutdown Delay), PowerChute sends a request to the Network
Management Card to shut down the cluster using the VxRail REST API.
The NMC issues the VxRail cluster API shutdown command. At this point,
all user VMs should be off.
- After 180 seconds
(Cluster Shutdown Duration), the cluster and ESXi hosts are shut down.
- PowerChute shuts
down the vCenter Server Appliance.
- After 240 seconds
(vCenter Server Appliance Shutdown Duration), PowerChute shuts down
the Management and Witness hosts, including the PowerChute VM. The
UPS will turn off shortly after this.
- The UPS will wait
the amount of time indicated by one of the following, whichever is
greater:
Low Battery Duration or Maximum
Required Delay
These are shown on the Configuration - Shutdown page in the NMC interface.
- After this delay, a further non-configurable
two minute delay is counted down.
- The UPS will then turn off after the
user-configurable Shutdown Delay time
has elapsed.
This is configurable on the Configuration - Shutdown page in the NMC
user interface.
It is recommended that the Low Battery Duration
is configured to allow enough time for the Operating System shutdown to
complete. Ideally the operating system should have shut down before the
non-configurable two minute delay (step 9) starts to count down.

file configured, PowerChute deployed as a VM.
PowerChute is deployed as VM inside the Cluster, configured for a Single/Redundant

- PowerChute starts
to shut down User VMs and vApps.
- After 2 minutes
(VM/vApp Shutdown Duration), PowerChute sends a request to the Network
Management Card to shut down the cluster using the VxRail REST API.
- PowerChute starts
to execute the shutdown command file.
- After the delay configured for the command file has
elapsed, PowerChute then starts a local OS shutdown to power
itself off. All user VMs must be powered off before cluster shutdown
can proceed.
- After 180 seconds
(Cluster Shutdown Delay), the NMC issues the VxRail cluster API shutdown
command. At this point, all user VMs including the PowerChute VM should
be off.
