Summary

BLAZE supports multi-server clustering, which allows up to 50 servers to operate as a single unified system. A single cluster supports up to 50 servers, with each server managing up to 256 camera channels, for a potential total of up to 12,800 channels across the cluster.

This article explains how to add and remove servers from a cluster.

Adding a Server

To add a new server:

1. Open BLAZE.
    
2. Navigate to Settings > Servers
    
3. Click Add server.
   
   
    
4. Ensure the new server is on the same Class C subnet as the existing cluster and running the same version.
   
   
    
5. Verify sufficient disk space is available.

When a server is added:

• The system automatically creates a database backup.
   
• Licenses are merged automatically.
   
• Existing cluster operations are not interrupted. Cameras and recording continue normally while the new server is being initialized.
   
• If the process fails at any step, the operation is cancelled and changes are rolled back.

Removing a Server

Before removing a server, verify cameras assigned to the server have been manually reassigned or that the remaining servers have enough channel capacity to absorb them.

If a server is removed while still running, it automatically detects that it no longer belongs to the cluster and stops communicating with other servers.

To remove a server:

1. Navigate to Settings > Servers
    
2. Right-click the server and select Detach.
