Hardware equipment and software environment for the Tivoli WebSEAL performance tests

Edit online

To perform our Tivoli WebSEAL performance tests, we created a customer-like environment. We configured the hardware and software, the network, the storage server, and the z/VM guests.

Host Hardware

Two LPARs on a 16-way IBM® System z9™, type 2094-S18, equipped with:
Table 1. System memory and CPUs
System/LPAR Memory Dedicated CPUs
z/VM® 5120 MB 3(4)
z/OS® 4096 MB 2(4)
Additionally, the z/VM LPAR used:
  • OSA Express 2 gigabit Ethernet card (OSA code level 0805)
  • Crypto type: CEX2C (Supplies 2 cards)

Network setup

  • The z/VM LPAR is connected to the clients via Fiber Gigabit Ethernet Interface
  • The z/VM guests used virtual guest LANs
  • The z/VM LPAR and the z/OS LPAR were connected via a HiperSockets™ connection

Storage server setup

IBM TotalStorage® Enterprise Storage Server® (ESS) 2105 800
  • IBM 3390 disk model 3
  • Physical DDMS with 15,000 RPMs

z/VM guest setup

Table 2 shows the z/VM guest configuration we used for our tests. We used this configuration for our tests using WebSphere® Application Server on z/OS and our tests using Apache HTTP Server on Linux®.
