VEEAM SOFTWARE SAVES THE DAY AT VMWORLD 2009
This is what happens when instead of comparing slideware, you put real software under real testing

Veeam Monitor picked up monitoring the environment from where primary competitor's product crashed, and was able to keep monitoring the whole environment as it was being increased 2 times in size since the point where competitive solution could not handle monitoring it any longer.
Moreover, unlike competitive solution, which had luxury of having dedicated physical host with of 16GB RAM, Veeam Monitor and its SQL backend database were running inside of a regular virtual machine! Besides, peak memory utilization recorded were 200MB for data collector process, and 150MB for user interface - and that is while monitoring 2400 VMs! Compare that with 14GB of memory usage noticed on competitive solution right before it crashed.
Technology beats everything!
