WebScale™
Equal Load Distribution
When selected, this parameter specifies that this host should take on equal portion of the
load balanced traffic in multiple hosts filtering mode for the associated port rule.
You can specify different load percentages for each host in the cluster by using the Load
percentage parameter instead of the Equal parameter.
Disabled Filtering Mode
This parameter specifies that all network traffic for the associated port rule should be
blocked. In this case, the WebScale driver will filter all corresponding network
datagrams. This filtering mode lets you build a firewall against unwanted network
access to a specific range of ports.
List of Rules
This window displays all currently installed port rules sorted by the port range. You can
select a rule by clicking anywhere within the rule. Once selected, you can modify a rule
by updating its parameters and clicking on the Modify button. You can also delete the
rule by clicking on the Remove button.
The number and type of rules must match across all of the machines in the WebScale
cluster. Please see section Port Rules for more information on this subject.
Setting Up the Windows NT Bindings
After you have installed WebScale and completed the WebScale Setup dialog, the next
and final step in preparing WebScale for use is to set the correct Windows NT bindings.
A binding specifies the interconnection between two Windows NT software
components, such as a networking protocol and an adapter card (network interface
card). The bindings need to be updated whenever a change occurs in the number of
installed components. You can change these bindings through the Network setup dialog
selected from the Control Panel folder. Please consult Windows NT documentation,
on-line help facilities or Resource Kit for more information on binding.
To review and setup the correct bindings for WebScale:
æ
Be sure that you have completed configuring WebScale through the WebScale
Setup dialog; please consult the Configuring WebScale section.
æ
Select the Bindings tab in the Windows NT Network setup dialog.
æ
If you have multiple network interface cards (NIC's) with one card dedicated for
use with the WebScale cluster, follow the instructions in the section Using
Multiple Network Interface Cards.
