CMS Failover Solution
Provide 1+1 Redundancy for Central Management System. In case if CMS service becomes unavailable, recording and management tasks will be transferred from CMS to a CMS redundant server.
CMS Failover License
Users can use the redundant server to takeover the CMS, no matter what number of active servers and cameras under this CMS.
Scenario:
CMS server connects with 50 cameras, and the user used 1 redundant-server for CMS. There are 3 active-servers for recording, and the channel of each active-server is 32, 40 and 50. The user uses 2 redundant-servers for backing up their servers.
How many licenses need to buy?
Formula:
• Camera license = Total channel of cameras minus free 32 channels.
• Substations failover license = the number of channels on the active server hosting the largest number of cameras multiplied by the number of redundant servers.
• CMS failover license = the number of CMS
• Total number of cameras: 50 + 32 + 40 + 50 = 172
• The free channel for VIVOTEK camera: 32
• The number of redundant-servers for active-servers: 2
• The number of redundant-server for CMS: 1
• The user needs to buy 140 (50 + 32 + 40 + 50 - 32) camera license, 100 (50 x 2) Substations failover licenses, and 1 CMS failover license for this scenario.
