Chapter 4 Configuring the CDS
Array Level Configuration
When grouping Streamers you should take into account network cost to stream, bandwidth usage, and
geographic locations of Streamers and QAM gateways. All Streamers in a group are considered to have
the same cost to reach a destination.
VVI with Split-Domain Management and CCP Streamers
A VVI with split-domain management has one manager (VVIM) that manages the Vaults and Caching
Nodes, and one manager (Stream Manager) that manages the Streamers.
When you use CCP Streamers in a VVI, all group IDs and server IDs need to be unique among all servers
in the VVI. The VVIM manages all the group IDs and server IDs for the VVI with CCP Streamers. The
Stream Manager gets an allotment of group IDs from the VVIM in one of two ways:
• During the initial installation, by way of the CDSM Setup page
• In the first-time configuration of Stream Groups
Communication between the VVI Manager and the Stream Manager is accomplished through database
replication when CCP is used as the protocol. The communication of groups and servers in a
split-domain management, has database replication among all servers. Therefore, the group IDs and
server IDs are communicated among all domains.
The CDSM Setup page for the Stream Manager has a field for the VVIM IP address. The VVIM IP
address is used to send an HTTP GET request to the VVIM for a range of group IDs. If the Stream
Manager is unable to reach the VVIM, either because port 80 is not open for communication or some
other connectivity reason, the Stream Group page displays a field for entering the beginning group ID.
The administrator of the Stream Manager gets the beginning group ID from the administrator of the
VVIM. The VVIM gets the beginning group ID on the Configuration Generator page. For more
information, see the “Identifying Server IDs and Group IDs for VVI with Split-Domain Management”
section on page 7-20.
For more information about the VVI settings on the CDSM Setup page, see the “Virtual Video
Infrastructure” section on page F-7.
Caution The beginning group ID must be generated by the VVIM, and if manually entered, it must be entered
correctly. Entering the wrong ID can cause cache-fill failures and other issues.
