Hi, I have few questions about 2-Node SCI setup where we have more than 3000 APs.
1.) Do both SCI nodes (master and data) have web GUI? 2.) Do we have to log into both SCI nodes to query data? 3.) How do controller select SCI node to send data? 4.) Do these two nodes have replicated data or unique data? 5.) Once AP is sending data to either of SCI nodes, is it fixed for all the time? 6.) Can we have master and data nodes in two geographical locations? 7.) Do we have to configure both SCI nodes in controller?
The bandwidth requirements will be about 15kB per 15 mins per AP. Of course this is just a ballpark number. The actual number will depend on the number of clients, sessions, etc.
The master-data node cluster is not a HA setup, though it provides data redundancy. So in the event that the master node fails, SCI will stop collecting data, but the data in the data node can be retrieved once a separate master node is setup.
So all the communication with node only happens through master node? All the data fetching from controller comes to master node and from there it is distributed between master and data node DBs?
