While looking for a backup solution for my VMware environment, I stumbled upon a very nice article by Kendrick Coleman on his blog on a top 10 list of carefully selected tools for managing your VMware vSphere deployments, and the best thing is that they are all free!!
Kendrick had also done video demos for these tools so you can pick the best without installing it.
Here is the link: Top 10 Free VMware vSphere Tools and Utilities for 2011
Nicely done Kenny!
