PowerChute Network Shutdown

Hello All,

I have several ESXi hosts that are newly configured and controlled by vCenter and I have 2 x APC UPS RT 6000XL which connect to the hosts in the rack.

I need to set up these UPS to shutdown my vms within the ESXi hosts once a certain threshold has been reached so what I was hoping to find out is the best way to configure this.

Can I simply install PowerChute Network Shutdown onto the vCenter and control the shutdown of vms from there or is it better to use vMA for the ESXi hosts?

Another question relates to the 'Sync Control' feature in APC. If i configure these 2 UPS devices in a group will it mean that they load balance their battery power on a power outage?

The recommended solution offered by APC, is to use a Network Management Card in the UPS, configure vMA, to send the commands to the ESXi servers to shutdown the ESXi servers.

Installing the APC Powerchute Network Shutdown software on ESXi ...

Make sure you are using a >Licensed version of ESXi, which I assume you are because you are also using vCenter Server.

The synchronization option allows you to have two or more UPS units with their output synched up with one another. In this scenario, you can remotely turn off or reboot one UPS and it will turn off/reboot other UPS units in the same sync group. This option is primarily used in cases where you have either a server or switch that has redundant power supplies.You will need one UPS per power supply. If one UPS were to fail, then the other UPS will support the other power supply. However, if you need to reboot the server/switch, you need to make sure that all power supplies are being rebooted. In this case, the sync group allows you to reboot one UPS, which in turn, reboots all that are part of the sync group. The problem that could occur is that if you had two UPS units that are part of the same sync group and are the two UPS' being monitored through Powerchute Network Shutdown. If you were to turn off/reboot one of the UPS units, the other would turn off/reboot as well. When this happens, the server would turn off/reboot as well. This is why we don't advise enabling sync control when using PCNS.*
