Server communication
Shared IP - same subnet
In a (Undefined variable: User_Guide.ProductAbbrev) Control Server and (Undefined variable: User_Guide.ProductAbbrev) Application Server configuration that uses a shared IP, the (Undefined variable: User_Guide.ProductAbbrev) Application Server appliances are separate standbys from the (Undefined variable: User_Guide.ProductAbbrev) Control Server appliances.
Examples:
- If the primary (Undefined variable: User_Guide.ProductAbbrev) Control Server fails, the secondary (Undefined variable: User_Guide.ProductAbbrev) Control Server communicates with whichever (Undefined variable: User_Guide.ProductAbbrev) Application Server is in control (either the primary or the secondary).
- If the primary (Undefined variable: User_Guide.ProductAbbrev) Application Server fails, the primary (Undefined variable: User_Guide.ProductAbbrev) Control Server communicates whichever (Undefined variable: User_Guide.ProductAbbrev) Application Server is in control.
No shared IP - different subnets
In a (Undefined variable: User_Guide.ProductAbbrev) Control Server and (Undefined variable: User_Guide.ProductAbbrev) Application Server configuration that does not use a shared IP, the (Undefined variable: User_Guide.ProductAbbrev) Application Server and (Undefined variable: User_Guide.ProductAbbrev) Control Server appliances failover in pairs.
Examples:
- If the primary (Undefined variable: User_Guide.ProductAbbrev) Control Server fails the primary (Undefined variable: User_Guide.ProductAbbrev) Application server is also brought down and the Secondary pair of appliances take control.
- If the primary (Undefined variable: User_Guide.ProductAbbrev) Application Server fails, the primary (Undefined variable: User_Guide.ProductAbbrev) Control Server is also brought down and the Secondary pair of appliances take control.
