I was listening to some VMworld talks during the weekend and something caught my attention which I hadn’t realized before. The talk I was listening to was VSP2122″VMware vMotion in vSphere 5.0, Architecture and Performance”. Now this probably doesn’t apply to most of the people reading this so let me set the scenario first: Different hosts from a CPU/Memory perspective [...]
I was just checking out some of the VMworld Sessions and one that I really enjoyed was the one on “Memory Virtualization” session by Kit Colbert and YP Chien (#VSP2447). This session has a lot of nuggets but something I wanted to share is this script that YP Chien / Kingston showed up on stage. This script basically shows you [...]
I was just playing around with esxtop in vSphere 5.0 and spotted something that changed. I figured there must be more so I started digging. I didn’t dig too deep as there is a great VMworld session (VSP1999) on this topic by Krishna Raj Raja and I figured why re-invent the wheel.

This week I had a call with a new and exciting company called Tintri. Tintri has been flying under the radar for the last couple of years and has worked really hard to develop a new product. Tintri was founded by some of the smartest kids on the block one of which is their current CEO and former EVP of [...]
Nothing deep technical this time, I just want to make clear how cool VAAI is! Last week I noticed on twitter that some people reported some nice figures around VAAI. I asked them if they were willing to run some tests and compare VAAI vs NON-VAAI runs. And these were some of the responses I received, I cut them down [...]
