CA TM Performance Metrics

Sizing the machine that will host the CA TM Server is important to ensure effective management. Depending on the size of your organization and the internal requirements, the CA TM Server does not necessarily have to be a server class system. However, it should ideally reside on a machine that is dedicated for this purpose.

CA performance testing provides the following examples for a single CPU and multiple CPU server class Windows system as the host machine for the CA TM Server:

• An entry level enterprise server, such as a single 3 GHz Pentium 4 class system with 4 GB of memory

  Manages approximately 5,000 clients with a 20% margin before the system reaches maximum capacity during the subnet discovery process.

• An enterprise level server, multi-core processor, such as multiple 3.2 GHz Pentium 4 Xeon system with 8 GB of memory

  Manages approximately 15,000 clients with a 25% margin for growth before the system reaches maximum capacity during the subnet discovery process.

Other factors that can affect these guidelines include:

• How often a subnet Discovery is performed on the network
• How many subnets are defined on the network
• The Election Method used when the Discovery is performed
• Speed of the network
• The type and speed of disk drives being used

Peak demand conditions do occasionally occur, but the CA TM Server adjusts for that and, when it becomes too busy to handle a given request, it can safely refuse to service a particular client request until resources become available.

Note: See the readme file for the latest operating system and hardware requirements for the CA TM Server and CA TM Agent.
