How to use more than 5 esxi hosts?

If i try to use more than 5 esxi hosts, than io analyzer gives a hint to use an other io analyzer controller VM.

So does this mean i will have to use two io analyzer controller vms,which means to two websites which are not synchronous?

Page 6 of the IO analyzer guide:

I/O Analyzer Configuration Maximums

I/O Analyzer 1.5.1 has been tested up to the following configurations:

   With up to 128 worker VMs per ESX/ESXi host.

   With up to five ESX/ESXi hosts per I/O Analyzer controller VM.

To run I/O Analyzer tests with more than five ESX/ESXi hosts, we recommend using multiple controller VMs.
