Figure 2-19 NetScaler 9000 system in High Availability and One-Arm Mode
(Single Subnet Environment)
 Stand-Alone
To use a NetScaler 9000 system in a single subnet environment and in a
stand-alone mode (not in high availability setup), the setup slightly varies
from that shown in Figure 2-18 and Figure 2-19. In this case, there is only
one NetScaler 9000 system instead of two NetScaler 9000 systems.
2.3.1.2 Multiple Subnets
In this type of environment, the NetScaler 9000 system’s IP address, its
mapped IP address (MIP), and the server’s IP address are on different
subnets. The NetScaler 9000 system can be used in one-arm or two-arm
mode.
Depending on whether the servers are on private (non-routable) subnets,
the NetScaler 9000 system can be used either in a public-public or public
private type of multiple subnet environments.
Note: If the NetScaler 9000 system is the default router for the servers, then
the layer 2 mode can be disabled.
All of the IP addresses shown in the example are in the same subnet.
