Server Map Configuration : Server Map Format Types

Server Map Format Types
Media Flow Controller provides three different server-map format-type options and a fourth for NFS that requires you to leave the format-type unspecified:
host-origin-map—Provides a way for you to configure multiple HTTP origin servers. The XML file performs a hash matching the Host header to an origin server/port defined in the file. You cannot use another server-map with this format-type.
cluster-map—Provides a way for you to use consistent hashing to bind objects to nodes in a cluster configuration. You can use this format-type with the origin-escalation-map to create a server map hierarchy, or you can use this map alone.
origin-escalation-map—Provides a way for you to configure multiple HTTP origin servers which are logically viewed as one. Requests are sequentially initiated to specific origin servers based on a configured weight, until the request is satisfied or all available origin servers have been tried. You can use this format-type with cluster-map to create a server map hierarchy, or you can use this map alone.
nfs-map—Provides a way to configure multiple NFS publishing points for origin. You cannot use another server-map with this format-type.
Note! For cluster-map and origin-escalation-map only, you can use as many, and in any combination, together or separately, as needed.
