TADDM server hardware requirements

Use this information to estimate the processor, memory, and disk space requirements for the TADDM servers in a synchronization or domain server deployment.

These guidelines are the minimum specifications for hardware sizing. Several factors, including the number of users, can affect server use.

Use the following general guidelines:
  • Use a fast multiprocessor system for the TADDM servers.
  • Using a small number of faster processors is generally a better solution than using a large number of slower processors. For example, a 4-way 3.6 GHz Intel implementation is preferable to an 8-way 2.0 GHz Intel implementation.
  • DB2® and Oracle databases that TADDM uses are configured to take advantage of multiple processors and parallel operations.
Note: When you run a TADDM server on virtualized hardware, use dedicated (static) resources. Shared (dynamic) resources might cause performance problems.

These guidelines assume that the TADDM server and the database server are on separate systems. You can install a TADDM server with a local database, but this is not recommended for production environments.

The following table indicates how to determine the server hardware requirements for your environment, based on the number of server equivalents (SEs) to be discovered.

Table 1. TADDM server hardware requirements
Server type Processors Processor speed Memory Prerequisite checker product code Disk space
Domain server with < 2000 SEs 2 2 GHz minimum, 3 GHz advised 8 GB TS1
  • 5 GB for product installation
  • 50 GB additional space (for DLA books, log and trace files, and other data)
Domain server with 2000 – 10,000 SEs 4 2 GHz minimum, 3 GHz advised
  • TADDM 7.3.0.2, and earlier: 8 GB
  • Fix Pack 3 TADDM 7.3.0.3, and later: 16 GB
 TS2
Synchronization server with > 10,000 SEs 4 2 GHz minimum, 3 GHz advised
  • TADDM 7.3.0.2, and earlier: 8 GB
  • Fix Pack 3 TADDM 7.3.0.3, and later: 16 GB, or more
 TS3
Anchor 2 2 GHz minimum, 3 GHz advised
  • TADDM 7.3.0.2, and earlier: 6 GB
  • Fix Pack 3 TADDM 7.3.0.3, and later: 8 GB
 n/a 5 GB
Windows gateway 2 2 GHz minimum, 3 GHz advised
  • TADDM 7.3.0.2, and earlier: 6 GB
  • Fix Pack 3 TADDM 7.3.0.3, and later: 8 GB
 n/a 2 GB
Note: For an anchor server, when exchanging data you must use Secure Shell (SSH) version 2 protocol.
