IP Groups

IP Group is the term used for grouping of multiple servers together, as a single entity. Faddom supports three types of IP groups:

IP Group with virtual IP

In this case, there is a single virtual IP address that is used by clients to access all IP group
members. This type of IP group is most commonly defined in a Load Balancer. Faddom
extracts the configuration of load balancers and automatically defines IP groups that
are defined there.

IP Group without a virtual IP

This is usually either a load-balancing IP group or an active/passive cluster. In this type of
IP group, there is no single front-end virtual server, but rather a group of servers, each
accessed separately by the clients.

Server with multiple network interfaces

This is actually a single server that has multiple network interfaces with separate IP
addresses. This server should be treated as a single entity and the IP addresses of the
network interfaces should be specified. Faddom automatically identifies and defines multiple
network interfaces for VMware and for AWS/EC2 environments.


Discovering IP groups from a load balancer

Faddom can discover the virtual IP definitions of load balancers, by extracting the data
about virtual servers and server pools from the load balancing server, using SNMP

To initiate IP group discovery from the IP Groups screen, select “Discover from Load
Balancer”. In the dialog that opens, either select an already defined load balancer or
define a new one. Click OK to save the definition and initiate IP group discovery.

It is also possible to define new load balancers, as well as administer load balancer
discovery setup, from the Configuration/Load Balancers screen. For details about SNMP
configuration and supported load balancer types, please refer to the documentation of
the Load Balancers screen.


Defining IP groups manually

To manually add/delete/update IP groups, use the IP Groups screen. When defining
new IP groups, select the type (as described above), optionally specify the behavior
(descriptive field), the virtual IP Address (when applicable), and the list of members.
