We just posted a new whitepaper today about the differences (and value and benefits) of a power management system that uses standalone agents versus no agents at all. You’ll be really surprised at the results. It answers the age old questions about the approaches, advantages and challenges of deploying technologies that use agents versus agentless ones.
I plan on going into this in greater detail here shortly, but for now, I’ll leave you with the link to download the whitepaper.
