System setup for the WebSphere Application Server performance tests

Edit online

To emulate a customer-like environment we needed to setup our network, the WebSphere Studio Workload Simulator client, the database, and WebSphere Application Server.

Network setup

Our network setup used a variation of two OSA cards, which includes either one (see Figure 1) or two (see Figure 2) private network connections. For some of our tests, the second OSA card shown in Figure 4 was replaced by a HiperSockets™ connection.
