The information TSM stores in the Active Directory consists of a list of TSM servers and associated clients. Each TSM server also contains the communications settings defined for that server. All information is stored in TSM-specific attributes that are installed as part of the schema extensions. A detailed description of the TSM Active Directory schema extensions is available from the TSM Web site at http://www.tivoli.com/support/storage_mgr/adwserv.htm.
Table 23 describes the attributes TSM uses to store information in
the Active Directory.
Attribute Common Name | Description | Parent Container/Class |
---|---|---|
IBM-TSM-SRV-ADDRESS | HTTP Address | IBM-TSM-SRV-TCPHTTPCLASS |
IBM-TSM-SRV-PORT | HTTP Port | IBM-TSM-SRV-TCPHTTPCLASS |
IBM-TSM-SRV-ADDRESS | Named Pipe Address | IBM-TSM-SRV-NAMEDPIPECLASS |
IBM-TSM-SRV-ADDRESS | TCPIP Address | IBM-TSM-SRV-TCPHTTPCLASS |
IBM-TSM-SRV-PORT | TCPIP Port | IBM-TSM-SRV-TCPHTTPCLASS |
IBM-TSM-SRV-NODENAME | Node Name | IBM-TSM-SRV-NODECLASS |
The Active Directory disk storage requirements are dependent on the number of TSM servers and clients registered for the particular installation. The disk storage requirement for a full replica can be represented by the following formula:
Disk Usage = NumberOfServers * ( 4.1KB + ( NumberofClients * 2.04KB ) )
The Active Directory disk storage requirements for Global Catalog servers (partial replicas only) are dependent on the same factors. The disk storage requirement for a partial replica can be represented by the following formula:
Disk Usage = NumberOfServers * ( 4.1KB + ( NumberofClients * 2.04KB ) )
Typical TSM usage will consist of only minor changes to the data stored in the Active Directory. This information will only change when new servers are defined, client nodes are registered, or communications parameters are changed. Since these parameters change very infrequently on a day-to-day basis, the network traffic requirement is very low. Network bandwidth required will be under 100KBytes of data per day for both partial and full replicas.
