Review this section and its sub-sections before you deploy a Virtual Sensor.
- Based on how you deploy the Virtual Sensor, you might have to re-configure some of the vSwitches on your VMware ESXi host.
- Currently, Virtual Sensors are not VMware vMotion aware. That is, you cannot move a Virtual Sensor between VMware ESXi hosts. You must manually deploy the Virtual Sensor in the other VMware ESXi hosts.
- You need an Active Fail-Open kit to deploy Sensor monitoring ports in fail-open mode. This is applicable to scenarios where the Virtual Sensor is between two physical network devices. For inline inspection of traffic to virtual machines, only fail-closed mode is applicable.
- Currently, the failover deployment of Virtual Sensors is not supported.
Note
Under test conditions, it is observed that it takes less than a minute for a Virtual Sensor to restart and become fully operational again. This factor mitigates the risk of significant network disruption due to inline Virtual Sensor monitoring ports going down. It is recommended to deploy Active Failopen Kit to avoid network disruption due to a restart of Virtual Sensor.
