2.3.1 Environment Planning
This section describes the environments in which the NetScaler 9000 system
can be deployed. Before you install the NetScaler 9000 system, use this
information to help you determine an appropriate environment for your
installation.
2.3.1.1 Single Subnet
In this type of environment, the NetScaler 9000 system’s IP address, mapped
IP address (MIP) and the server’s IP address are on the same subnet. The
NetScaler 9000 system can be deployed in one-arm or two-arm mode.
 Two-Arm Mode (Inline), High Availability
Figure 2-18 on page 15 shows a single subnet environment where the
NetScaler 9000 system is in a high availability setup, placed between two
layer 2 switches in a two-arm configuration.
The two NetScaler 9000 systems with their IP addresses, mapped IP addresses
and the servers with IP addresses are on the same subnet.
