WebScale™
This section lets you enter information that is specific or unique to each host in the
WebScale cluster. The values in this dialog box are:
the Host priority, which specifies this host's unique traffic handling priority for
TCP and UDP ports not managed by the Port Rules section of the WebScale
Setup dialog and is used in case a host within the cluster fails,
the Initial state, which specifies whether this host should immediately join the
cluster when Windows NT is started, and
the Dedicated IP address, which specifies this host's unique IP address used for
network traffic not associated with the cluster (for example, telnet access to a
specific host within the cluster).
the Subnet mask for the dedicated IP address.
For more information on each of these parameters, please refer to the corresponding
subsections.
Host Priority
This parameter specifies a host's unique priority for handling default network traffic for
TCP and UDP ports that are not otherwise specified in the Port Rules section of the
WebScale Setup dialog. It is used in case a host within the cluster goes offline, and it
determines which host within the cluster will take over handling this traffic if required.
The allowed values for host priority range from 1 to the maximum number of hosts (as
specified by your license key). Lower numerical values indicate higher priorities; the
value 1 is the highest priority. Each host within the cluster must specify a unique host
priority.
The host with the highest priority (that is, the lowest numerical value) among the
current members of the cluster will handle all of the cluster's default network traffic. If
this host fails or goes offline, the host with the next highest priority within the cluster
will take over handling this network traffic. This mechanism ensures that the cluster
provides fault-tolerance in the handling of network traffic for all ports. You can
override these priorities or provide load balancing for specific ranges of ports by
specifying rules within the Port Rules section of the dialog.
