Chapter 6: Administering Virtual Clusters
142 Equalizer Installation and Administration Guide
Adding a Server to a Cluster
To add a server to a virtual cluster, follow these steps:
1. Log into the Administrative Interface using a login that has
add/del
access for the cluster (see “Logging In” on
page 52).
2. In the left frame, right-click the name of the cluster to be configured and select the
Add Server
command from
the menu.
3. Enter the following information:
Unless you want to set up port redirection, you can accept the default value; to redirect to a port other than the
cluster port, enter the appropriate value for
Server Port
.
Server Name
The logical name for the server, or accept Equalizer’s default. Each
server must have a unique name in the cluster that begins with an
alphabetical character (for example,
CPImages) .
Server IP Address
Enter the dotted decimal IP address of the server. This is the address
Equalizer uses to communicate with the server.
Server Port
Enter the numeric port number on the Equalizer to be used for traffic
between Equalizer and the server. For Layer 7 clusters, the default
server port is 80.
[Note that in
Layer 7 HTTPS clusters, Equalizer performs all the SSL
encryption and decryption and forwards traffic to the servers using the
HTTP protocol. This is why when you add servers to an HTTPS cluster,
the default server port is 80 (and should always be a port other than
port 443).]
For L4 UDP and L4 TCP protocol clusters, a cluster
port range can be
defined. These are the ports on the Equalizer to be used to send traffic
to the servers in the cluster. Port ranges allow Equalizer users to create
a single cluster to control the traffic for multiple, contiguous ports. The
Server Port defined for a server in the cluster for which a port range is
defined indicates the port on the server that starts the range of ports to
be opened (see below).
Associate with
Virtual Machine
When enabled, this option leads you through the process of associating
this server with a VMware Virtual Machine. See “Associating a Server
with a Virtual Machine” on page 299. This option is disabled by default.
Quiesce on creation
When enabled (the default), this option prevents any traffic from being
routed to the server by enabling the
quiesce
option on the server. Once
the server is functional, you can disable the
quiesce
option on the
server’s
Configuration
tab. If the server is already configured for
operation when you add it to Equalizer, you can disable this option.
