Tips for designing the hub and spoke server configuration
In designing the hub and spoke configuration, especially consider the resource requirements for status monitoring. Also, consider how you want to group hub and spoke servers and whether you want to use multiple hub servers.
Use the Operations Center System Requirements Calculator to estimate the system requirements for running the Operations Center and the hub and spoke servers that are monitored by the Operations Center.
Primary factors that affect performance
- The processor and memory on the computer where the Operations Center is installed
- The system resources of the hub and spoke servers, including the disk system that is in use for the hub server database
- The number of client nodes and virtual machine file spaces that are managed by the hub and spoke servers
- The frequency at which data is refreshed in the Operations Center
How to group hub and spoke servers
- The administrator who manages the servers
- The organizational entity that funds the servers
- Server operating system
- The language in which the servers run Tip: If the hub and spoke servers are not running in the same language, you might see corrupted text in the Operations Center.
How to group hub and spoke servers in an enterprise configuration
In an enterprise configuration, a network of IBM Spectrum Protect™ servers are managed as a group. Changes that are made on the configuration manager can be distributed automatically to one or more managed servers in the network.
The Operations Center normally registers and maintains a dedicated administrator ID on the hub and spoke servers. This monitoring administrator must always have the same password on all the servers.
- Designate the configuration manager server as the Operations Center hub server. During the hub server configuration, a monitoring administrator ID named IBM-OC-hub_server_name is registered.
- On the hub server, add the monitoring administrator ID to a new or existing enterprise configuration profile. Issue the NOTIFY SUBSCRIBERS command to distribute the profile to the managed servers.
- Add one or more of the managed servers as Operations Center spoke servers.
The Operations Center detects this configuration and allows the configuration manager to distribute and update the monitoring administrator ID on the spoke servers.
When to use multiple hub servers
- A single server cannot be both a hub server and a spoke server.
- Each spoke server can be assigned to only one hub server.
- Each hub server requires a separate instance of the Operations Center, each of which has a separate web address.
