Single Site
Active-Active Redundancy for Recording
Primary and Secondary recorders are part of a single Milestone deployment that utilizes one database. It is important to note that clustered SQL databases, clustered Management Servers, and the Milestone Management Server Failover are all classified as a 'Single Site' because they operate on a single unique database.
This setup ensures redundancy for the Recording Servers only. To achieve redundancy and failover for other Milestone components, solutions such as Milestone Management Server Failover, Windows Clustering with AlwaysOn SQL, or Evidian Clustering must be deployed in conjunction with RMF.
Pros
Lower cost: Usually, fewer servers result in lower infrastructure costs.
Cons
Weak Cybersecurity Design: Even with Always-On SQL clustering, there is only one effective database. A hack into one copy is a hack into all copies and will compromise all video security.
Potential Outages during Upgrades: Even if clustering is used for failover, during software upgrades, all nodes must be taken offline and upgraded. The system experiences a loss of functionality during the process, which worsens if there are issues during upgrades, potentially causing all video security to fail.
