Load Testing on a grand scale – Lots of machines needed
Here’s a problem I need help solving.
How do you load test an application when the application makes remote calls to Windows machines, uses WMI to collect and return information and stores the info in a central database?
We can fake it by calling each machine more than once but this isn’t exactly the same. I can tell you the other ways we’ve tried to solve the problem creatively but I’d rather not get into that right now.
I’m looking for access to 4000-5000+ machines. The machines can be physical or virtual. They can be windows or linux. I’d prefer more windows than linux. A user account that has admin type privileges is required so that we can read the data off the machines (although someone else can type in the password so we don’t have to know it). The system has to collect data for 1-2 months.
On a side note – there are other types of applications out there that do this type of stuff. Does anyone know how they load test?
If you know of anyone who might know someone that would have access to this many machines or perhaps work on a product like cirba, or microsoft systems center (formerly MOM), or VMware’s consolidation planning tool – I’d love to talk to them (even if we make a competing product
)

I have some experience with half of that problem – testing how the system deals with all the information being sent back. Give me a shout for ideas on how we simulated load. It took a small team to develop it, with our expert Linux/networking setting up the hardware, network and virtual IPs.
