IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Locating and sizing the Tivoli Enterprise Portal Server
Install the portal server on a very fast server with at least 2 processors. Memory requirements are described in Table 1.
The Tivoli Monitoring V6.3 release has been tested with 100 concurrent portal clients on 64-bit platforms. See the Tivoli Enterprise Portal Server for more details.
For optimal performance, place the portal server in the same data centers as most of the end users. Depending on firewall restrictions the location of the portal server has to be verified. If clients are not allowed to connect to a central segment they are not able to use the portal server.
If you have multiple large data centers you might need to install a second read-only portal server. If you choose to use this option, be aware that only one portal server can be used to make customization changes such as editing workspaces and situations. See the section on high availability for details on how to configure multiple portal servers.
For more information see Memory and disk requirements.
