HA-Cluster
A single FortiSandbox device can scan a limited number of files in a given time period. To handle heavier loads, you can use multiple FortiSandbox devices in a load-balancing high availability (HA) cluster.
There are three types of nodes in a cluster: primary, secondary, and worker.
|
Primary |
The primary node (Unit 1 in the diagram) manages the cluster, distributes jobs and gathers the results, and interacts with clients. It can also perform normal file scans. All scan-related configuration should be done on the primary node and they will be broadcasted from the primary node to the other nodes. Any scan-related configuration that has been set on a worker node will be overwritten. On the primary node, users can:
Although all FortiSandbox models can work as a primary node, we recommend using a more powerful model. |
|
Secondary |
The secondary node (Unit 2 in the diagram) is for HA support and normal file scans. It monitors the primary node's condition and, if the primary fails, the secondary will assume the role of primary. The former primary will then become a secondary when it is back up. To support failover, ensure both the primary and secondary nodes are configured correctly: |
|
Worker |
The worker nodes (Units 3–5 in the diagram) perform normal file scans and report results back to the primary and secondary nodes. They can also store detailed job information. Workers should have their own network settings and VM image settings. Workers can be any FortiSandbox model including FortiSandbox VM. Workers in a cluster do not need to be the same model. |
The total number of worker nodes, including the secondary node, cannot exceed 100.
For heavy job loads, use more powerful FortiSandbox models.
