During our session at the Dutch VMUG Frank was explaining Resource Pools and the impact of limits and reservations. As I had the feeling not everyone in the room was using resource pools I asked the following questions: How many people are using Resource Pools today?

Recently Dennis Zimmer, which most of you probably know of Icomasoft or from the books he authored, emailed me about a new tool his company was developing. I watched the video that is hosted on opvizor.com and must admit that it looks promising. Especially as most solutions today are reactive or semi-pro-active and opvizor is aiming to be pro-active. opvizor [...]
