Array Level Configuration
You can use only alphanumeric characters (0-9, a-z, A-Z), the dash (-), and the underscore (_) to create
a Site name.
Step 4 Add the appropriate Stream Groups, Vault Groups, and Cache Groups to the site.
The unassigned groups are listed along with a drop down-list for each that offers the options described
in Table 4-25.
Step 5 Click Submit.
To reset the field, click Reset.
To view the members of a site, choose the site from the drop-down list and click Display.
To delete a site, first remove all groups from the site, then click Delete Site.
Configuring Cache-Fill Bandwidth Using Thin Pipe Mapping
The Thin Pipe Map page allows you to configure low-bandwidth connections between local and remote
sites. A local site consists of groups of servers in the same site, for example, all the Streamers in a Stream
Group are considered part of the same site, or local site. A remote site consists of groups of servers in
other Stream Groups, Cache Groups, and Vault Groups. Before you can configure thin pipes, you must
define the sites. For more information, see the “Configuring Sites” section on page 4-73.
There can be multiple thin pipes configured for each local site. As an example, a site with Caching Nodes
organized into a Cache Group could have one 500-Mbps thin pipe going to a site with a Vault Group,
and a second 500-Mbps thin pipe going to a site with a Stream Group. The thin pipes are completely
independent of each other.
The Thin Pipe Map page also allows for the configuration of thin pipes in a hierarchy, where a remote
site must be reached through several pipes. For example, a Cache Group could have a 500 Mbps thin
pipe over which it streams to multiple Stream Groups. Each Stream Group could have separate 100 Mbps
thin pipes. In this case, the Cache Group traffic on egress to all Stream Groups is limited to 500 Mbps,
while ingress traffic to each Stream Group from this Cache Group is limited to 100 Mbps.
Note The Thin Pipe Map page is displayed only if Thin Pipe Management is enabled. See the “Thin Pipe
Management” section on page F-6 for more information.
For CCP traffic to work properly in the CDS, the following configuration needs to exist:
• Thin pipe mapping must be configured in the CDS.
• DiffServ AF settings must be configured on the CDS servers.
