There is nothing specific that I know of for ESXi but you could use standard load tools for the VMs that stress the memory, cpu and disk and that will stree the host -
Thanks. I have used that method in the past and will continue but, I was hoping there might be a virtual appliance designed specifically for ESXi stress testing.
Anybody have a bias or recommendation for any specific compute resource load/stress tool(s). These are diskless Hosts so only concerened with Memory and CPU.
