Multiple Client Server Topology

The CommandCenter Server application can support multiple clients. The CommandCenter Client installation does not require SQL. The CMDCTR-SYS-SNMP option enables the SNMP features in all clients.The CMDCTR-SERVER-RED redundant server option uses a licensed version of SQL Server for SQL mirroring. The CommandCenter Client or CommandCenter witness application acts as an independent watchdog for the CommandCenter server and SQL, with manual or automatic changeover. CCLink protocol is used between server and clients. (Multicast network packets are used for status updates to reduce duplication of network packets.)
