Hub and spoke server requirements
When you open the Operations Center for the first time, you must associate the Operations Center with a Tivoli® Storage Manager server that is designated as the hub server. In a multiple-server environment, you can connect the other servers, called spoke servers, to the hub server.
The spoke servers send alerts and status information to the hub server. The Operations Center shows you a consolidated view of alerts and status information for the hub server and any spoke servers.
If only one Tivoli Storage Manager server is monitored by the Operations Center, that server is still called a hub server, even though no spoke servers are connected to it.
Table 1 indicates the version of Tivoli Storage Manager server that must be installed on the hub server and on each spoke server that is managed by the Operations Center.
| Operations Center | Tivoli Storage Manager on the hub server | Tivoli Storage Manager on each spoke server |
|---|---|---|
| V7.1.3 | V7.1.3 or later | V6.3.4 or later Restriction: Some Operations Center function is
not available for servers that use a version earlier than V7.1.3.

Number of spoke servers that a hub server can support
The number of spoke servers that a hub server can support depends on the configuration and on the version of Tivoli Storage Manager on each spoke server. However, a general guideline is that a hub server can support 10 - 20 V6.3.4 spoke servers but can support more V7.1 spoke servers.
