Worker Nodes

When TOS is first installed on a server, the deployment becomes a cluster with a single node. Performance and functionality improvements can be achieved by adding additional worker nodes (servers) to the cluster. These additional nodes need to have the operating system installed but do not require installation of TOS, because the relevant services are installed when adding the node.

Worker nodes add computing power and may be needed to meet the demands of scaling up such as increasing the number of monitored devices or increasing frequency of revisions. When new worker nodes are added, some of the compute functions will be performed on them rather than on the primary data node, or other data nodes, leaving them more free to handle system management functions. There is almost no limit to the number of worker nodes that can be added but this must only be done under the guidance of Tufin support.

Before adding a worker node, consult with your account manager to make sure your requirements justify it. If your system doesn't require the additional processing power afforded by adding nodes, you will not experience any performance benefits.

You can remove worker nodes if their processing power is no longer required. After a node is removed, any compute functions it was handling will be handled by the remaining nodes.

List the nodes in your cluster by running the command sudo tos cluster node list.
