Add a server to increase capacity

Preparation​

Identify the module needing additional resources: SAST, DAST or SCA. Prepare a new server and network access to the existing Core. Additional hardware does not expand license rights. Do not use a complete DerScanner installation instead of connecting a scanner to the existing Core.

Procedure​

  1. Record the current server roles, module sets and versions. Check the main server's health and available concurrent-task allowance.
  2. Add the new server under Servers, confirm its key fingerprint and select Check as described in Core, SAST, DAST and SCA on separate servers.
  3. Select Install a module. Choose the complete module set needed on this new node. Set Address of the main server to the existing Core address reachable from the new server's network.
  4. Select a suitable delivery folder or wait for the online download description under What happens. Select Install.
  5. After completion, check that the new server belongs to this Core and all selected modules run. Check the existing servers and perform test tasks.
  6. For SAST, configure concurrency using Multiple SAST agents and concurrent tasks. Observe load at the current values before changing the number of tasks on an individual server.

Result and recovery​

The new node should appear as a scanner server of the existing Core. A main server of its own is a different role and does not represent successful expansion.

If the new node fails, retain the working previous configuration and check its role, version, SSH connection and Core queue access. Do not remove existing servers to solve a problem with the new one. To retire the new node, use Stop or remove components and servers: deleting its list entry alone does not stop its modules.
