My VMware Fling Contest idea: Load Simulator appliance


Load simulator virtual appliance (Linux) that will integrate with vCenter to rapidly deploy Linux VMs that generate CPU, memory, network, storage, and Fault Tolerance workloads.


When deploying vSphere on new hardware (server, network, storage) there is currently no simple way to stress test it before certifying it for production use. Want to answer questions like:
• Is virtual and physical network configured correctly and not causing perf issues? Are packets being dropped? Is the 1GB network connection allowing up to 1GB of bandwidth?
• Is the server's memory reliable?
• How will FT affect my network design?
• What happens to my hardware when fully maxed out?
• How does storage handle IO workloads being generated from different hosts?


Single simple tool to stress test new vSphere hardware / vSphere installations. Could also be used to test vSphere share mechanisms. Not intended to simulate actual workloads.


Load Simulator virtual appliance with a web base UI connects to vCenter and allows admins to rapidly deploy stress test VMs with various CPU, memory, network, storage, and FT sizes. The stress test VMs would generate CPU, memory, network, and storage based upon choices in the UI. For example:
Load Simulator UI would gather all vSphere Events in consolidated view. Furthermore, it would gather key perf metrics from the vSPhere Perf UI and roll them up into a perf chart. The Events and Perf view would make it easy to identify issues with HW and perf during the test.

Example Use:

Building out new blade based host running latest version of vSphere. Once environment is configured as per design spec, navigate to the Load Simulator UI and configure the test to deploy 50 stress test VMs in Small, Medium, and Large configurations. Monitor vSphere events and performance using Load Simulator UI to see if any bottlenecks are occurring. If issues are not occurring use the Load Simulator UI to add 10 more VMs and then recheck perf. Let stress test run for an hour and recheck perf. If all looks well, click on the cleanup button and the stress test VMs are automatically deleted.
