In a one-arm setup, you connect the NetScaler appliance to the network through a single VLAN. The appliance receives the request from the client on a single VLAN and it sends the request to the server on the same VLAN. This is one of the simplest deployment scenarios, where the router, the servers and the appliance are all connected to the same switch. Client requests at the switch are forwarded to the appliance, and the appliance uses the configured load balancing method to select the service, as is shown in the following diagram.
Figure 1. Load Balancing in One-Arm Mode
In the example
scenario, the services Service-ANY-1, Service-ANY-2, and Service-ANY-3 are
created and bound to the virtual server Vserver-LB-1. The virtual server load
balances the client request to a service. The following table lists the names
and values of the entities configured on the appliance in one-arm mode.
To configure a load balancing setup in one-arm mode, see "Setting Up Basic Load Balancing."
