Functions of the View Connection servers


The View Connection servers form the core of the View environment. They manage the following tasks:

  • Administration Interface: The View Composer hosts the Administration Interface for systems administration access. Both the first View Connection server and any replica View Connection servers will host an administration interface. The administrative interface can be accessed via the URL https://<View Connection Server FQDN>/admin.

  • Entitlement Management: The View Connection server manages the permissions that each user has to each desktop. It also manages the long-term assignments of dedicated desktops or full-clone desktops. Entitlements are stored in the local ADAM database.

  • Creation of full-cloned desktops A full clone is a copy of a VM that is independent of the parent VM. Changes to a full clone are separate from the parent VM.

    The View Connection server will issue commands to the View Composer to manage the full-cloned desktops. This includes storing information about the current state of the full-cloned desktop and monitoring the virtual desktop agent's status.

  • Creation of link-cloned desktops: A link-cloned desktop is a copy of a VM that shares virtual disks with the parent VM in an ongoing manner. Changes can be made to the parent VM and imaged over the rest of the link-cloned desktops. Link-cloned desktops share storage in a space-efficient manner that greatly reduces storage size requirements.

    The View Connection server will issue commands to the View Composer to manage the link-cloned desktops. This includes storing information about the current state of the linked clone and monitoring the virtual desktop's agent status during a recompose, refresh, or rebalance action. The View Connection server monitors the quantity of desktops, both available and in use. Based on the provisioning requirements set on the link-cloned pool, it will allocate additional desktops to meet demand.

  • Agent/Client session broker: The View Connection server is responsible for setting up sessions between clients (client application, thin clients, zero client, and so on) and the virtual desktop agents. It manages a list of entitlements for each View pool and will assign appropriate desktops to the user when they log in.

  • View HTML access: When installed, HTML access permits users to log into their virtual desktops using a common web browser. This allows users to quickly access virtual desktop resources without requiring local installation of the View agent.

  • ADAM Replication: The majority of View Connection server's configuration and state information is stored in an ADAM database. View Connection servers will replicate this data between each other continuously to maintain a consistent state across a cluster of View Connection servers.
