TV VVI Management
The TV VVI offers two types of management, centralized and split-domain.
In a CDS, Streamers cannot communicate with Streamers in other groups. In a VVI, Streamers in other
groups can communicate with each other on an as-needed basis.
All Vaults, Streamers, and Caching Nodes are identified by an array ID, a group ID, and a server ID. In
the CDSM GUI, the array ID identifies servers that are part of the same system, the group ID identifies
servers that are part of the same group (Vault Group, Cache Group, and Stream Group), and the server
ID is a unique number that identifies the server. Table 2-1 lists the CDSM GUI ID names and maps them
to the CServer names in the setupfile and .arroyorc files.
