Next, a Virtual Farm or multiple farms must be configured on the WebMux. A virtual farm
is a single representation of the servers to the clients. A farm consists of a group of servers
that service the same domain, website or services. For example, to configure a farm (or
virtual farm) to serve www.cainetworks.com:
• First, Server 1 and Server 2 would each need the website www.cainetworks.com
configured on them and HTTP/HTTPS services started, and
• Second, a farm on the WebMux is defined with Server 1 and Server 2 in it. The
servers would be setup to either share the traffic, or setup as a primary server and
standby server. In either case, if Server 1 goes down, then all traffic will be
automatically directed to Server 2 by the WebMux.
3.3 Two-armed Transparent Mode
In Two-Armed Transparent Mode, the servers need to be isolated from rest the network with
the WebMux in between, even though they are in the same network segment. All
communication from servers to other servers or clients must flow through the WebMux. The
WebMux will load balance any traffic targeted to the farm address and let all other traffic
flow through like a network cable. This simplifies some network configuration, but the
server isolation is an additional requirement.
3.4 One-armed Single Network Mode
In One-Arm mode, the WebMux supports both Single Network Mode and Out-of-Path Mode.
For Single Network Mode, there are no changes to the network or servers. Traffic from
clients send to the farm address on the WebMux, which will in turn send to the servers
through load balancing methods. Server replies to the WebMux will be sent back the clients.
Single Network Mode has a limitation that only 65000 concurrent connections are allowed in
one farm.
3.5 One-armed Out-Of-Path Mode
In Out-of-Path Mode, only one network in the setup (the server LAN) is connected to the
Internet through the firewall and router. Internet traffic or local connections can both be
directly sent to the WebMux, which forwards the packets to the proper server(s), then the
server routes the return traffic back to the remote or local clients directly.
