Using Clustering
NetScaler Gateway can be deployed in cluster configurations to provide high throughput, high availability, and scalability for VPN client traffic. In a cluster, a group of NetScaler Gateway appliances or VMs operates as a single system image to coordinate user sessions and manage traffic to network resources. A NetScaler Gateway cluster can be built with a minimum of two and a maximum of 32 NetScaler Gateway appliances or VMs configured as cluster nodes.
Read the NetScaler Clustering documentation before starting to configure your NetScaler Gateway cluster. Pay special attention to the following topics in that documentation.
-
See Hardware and Software Requirements to verify that the systems you plan to use meet the requirements.
-
See How Clustering Works for a description of clustering concepts.
-
See Setting up Inter-Node Communication to plan the deployment and identify any caveats that might be relevant to your environment.
A NetScaler Gateway cluster operates as a spotted VIP configuration type NetScaler cluster.
Important:
The XenApp and XenDesktop® wizard is not supported for clustering and hence you do not find the XenApp and XenDesktop wizard in the GUI > Navigation pane > Integrate with NetScaler products section.
