A couple of weeks ago I received a cool PDF via email, this week it appeared online(source blog). Check it out:
The Source PDF:
VMware has collaborated with Cisco to produce a guide for deploying VMware Infrastucture 3 with Cisco switches. This guide covers the physical and virtual data network and storage network deployment considerations for ESX [...]

Just noticed the following topic, which definitely contains some good info about how ESX deals with memory. Thanks to Kit for clearing things up. These posts are valuable, keep ‘em coming!
a short outtake:
Basically how aggressive do you want TPS to scan for shared pages? Obviously TPS has a cost to running in terms of CPU, [...]
