Run Deep Security Manager as multiple nodes
Instead of running Deep Security Manager on one server, you can install Deep Security Manager on multiple servers ("nodes") and connect them to one shared database. This provides better:
You can log in to any node. Each node can do all types of tasks. No node is more important than any of the others. A node failure does not cause service downtime, and does not result in data loss. Deep Security Manager processes many concurrent activities in a distributed pool that all online nodes execute. All activity that does not happen due to user input is packaged as a job, and runs on any available manager (with some exceptions for "local" jobs that are executed on each node, like cache clearing).
Each node must run the same Deep Security Manager software version. When you upgrade, the first manager you upgrade will temporarily take over all duties and shut down the other nodes. On Administration > System Information, in the Network Map with Activity Graph of the System Activity area, other nodes' status will be "Offline" with an indication that an upgrade is required. Once upgrade, nodes will automatically return online and begin processing again.
Add a node
Running multiple nodes requires either a Microsoft SQL Server or Oracle Database.
To add a Deep Security Manager node to the system, run the Deep Security Manager installer on a new computer. When prompted, type the location of and login credentials for the database. Once the installer connects to the database, you can continue to add the node.
Remove a node
Before you remove or replace a server, you should remove it from the pool of Deep Security Manager nodes.
Halt the service or uninstall Deep Security Manager on the node that you want to remove.
Its status must change to "Offline".
- Log into Deep Security Manager on another node.
- Go to Administration > Manager Nodes.
Double-click the node that you want to remove.
The node's Properties window should appear.
- In the Options area, click Decommission.
Viewing node statuses
To display all Deep Security Manager nodes along with their status, combined activity, and jobs being processed, go to Administration > System Information. From the drop-down menu, select which graph you want to view.
Network Map with Activity Graph
The Network Map with Activity Graph in the System Activity area displays a map of all installed manager nodes and their current status as well their relative activity over the last hour. The nodes can be in the following states:
- Offline (Upgrade Required)
Jobs by Node
This chart displays the number of jobs carried out over the last hour by each node.
Jobs by Type
This chart displays the jobs carried out over the last hour by type.
Total jobs by node and type
This chart displays the number of job types for each node over the last hour.
