Configuring collocated servers for the Dispatcher component
Learn about advanced features for configuring the Dispatcher component with collocated servers.
About this task
Important: A collocated server
competes for resources with Load Balancer during times of high traffic. However, in the absence of
overloaded machines, a collocated server offers a reduction in the total number of machines
necessary to set up a load-balanced site. On Linux, the
collocation feature depends on TUN module. Hence, before you configure collocation, ensure that the
TUN module is supported on the Linux version you are using.
Also, performance and function depend on the TUN module. To configure a server to be collocated, the
dscontrol server command provides an option called collocated which can be set to
yes or no. The default value is
no. Alternatively, you can use the GUI to set collocated parameter under the
configuration settings tab of the server object. The address of the server must be a valid IP
address of a network interface card on the machine.
Tip:
- The neighbor state of a collocated server is always available.
- Manager and advisor works as usual with collocated server.
- Multiple clusters can have collocated server.
- Metric server should not be used with collocated server.
- In case you are using IPv4 or IPv6 clusters, the Load Balancer machine should be in both networks before you configure it.
