RDS Collections
Collections allow users to use the environment intended for them.
Ahola and Special collection is "stable". Externals collection is "ext-stable". All customers test-environment is "nightly".
Each collection need at least these servers: Hosts, RD Connection Broker, RD Gateways and Web Access (GW machines), licensing (Datapump). RDS Broker directs the user to the correct host machines via Collection.
There is some collection deployment settings regarding to session time out and user profile disks. User Profile Disks are deployed on Datapump server, because netapp volume is not compatible with RDS collection and protocols what it use.
