About the SVM selection algorithm

Light Agents can apply one of the following SVM selection algorithms for connection:

• A standard SVM selection algorithm.

  If this algorithm is applied and you are using the application under a standard license, after installation and startup on the virtual machine, the Light Agent tries to connect to the SVM deployed on the same hypervisor on which the Light Agent is running. If there are no SVMs available for connection on the hypervisor on which the Light Agent is running, the Light Agent selects the SVM with the lowest number of Light Agent connections from a list of SVMs deployed on other hypervisors.

  If this algorithm is applied and you are using the application under an enterprise license, after installation and startup on the virtual machine, the Light Agent selects the SVM to which the least number of Light Agents are connected, regardless of the location of the SVM in the virtual infrastructure.

• An extended SVM selection algorithm.

  An extended SVM selection algorithm may be applied only if you use the application under an enterprise license.

  If this algorithm is applied, you can specify in the Light Agent policy how Light Agents should take into account SVM path. For example, a Light Agent can connect to an SVM deployed on the same hypervisor cluster or in the same Datacenter as the Light Agent. However, the SVM location does not have to be taken into account when a Light Agent selects an SVM.

  When selecting an SVM, Light Agents take into account the number of connected Light Agents to ensure that Light Agents are evenly distributed between SVMs that are available for connection.

  If an advanced SVM selection algorithm is applied and you selected a custom list of SVM addresses as the method for Light Agents to discover SVMs, Light Agents can connect to SVMs only if the location of the SVM is not taken into account.

If you use the application under an enterprise license, you can specify the SVM selection algorithm to be used by the Light Agents.

If you use the application under a standard license, Light Agents use the standard SVM selection algorithm to select SVMs for connection.

Regardless of the algorithm used in selecting SVMs, Light Agents also take into account the following parameters:

• Availability of a valid license (a non-blacklisted license key is added to the SVM, and the license validity period associated with the key has not expired). Light Agent first connects to the SVM on which the application is activated (the key is added).
• Type of the license key added to the SVM. If you add a server or desktop key to the SVM, the Light Agent first connects to the SVM on which the key type corresponds to the operating system installed on the virtual machine.
• Encrypting the connection between a Light Agent and SVM. A Light Agent for which connection encryption is enabled can connect only to SVMs on which connection encryption is also enabled. A Light Agent for which connection encryption is disabled can connect only to SVMs on which connection encryption is also disabled or protection is enabled, but a non-secure connection is allowed.

If you use the application under an enterprise license, Light Agents also use SVM connection tags when selecting the SVM. If a Light Agent has been assigned a tag, this Light Agent can connect only to SVMs for which connection of Light Agents with the specified tag is allowed.
