Thoughts on changes to TPS behavior in vSphere
This week VMware released a blog post and several knowledgebase articles about Transparent Page Sharing (TPS). In the next patch for ESXi, TPS will be disabled by default between virtual machines. TPS is the technology that allows virtual machines running on the same ESXi host to share identical memory pages, allowing ESXi to overcommit memory. This technology has been part…
Blogging is hard
As I type this, I see I haven’t written a blog post in over 5 months. I wish I had a good excuse for that but I don’t. The truth is it was really a number of different things: 1) Writing 3 books in one and a half years (from Nov. 2012 to April 2014) consumed a huge amount of…

One Weird Trick to Virtualize Monster VMs–Consultants Hate This!
We’ve all seen those ads on the Internet that promise to teach us “one weird trick” that “<someone> hates” to do something easily. Make money fast? Yep. Lose belly fat? Check.

Perception is Reality When Virtualizing Business Critical Apps
It’s been too long since I’ve blogged anything on a regular basis. Sorry about that. I would love to blame it on the three books I’ve written in the last year but that isn’t the only reason. Hopefully I can turn it around and start writing on a regular basis again. I’ve been sitting on this one for a while…
Virtualizing Exchange and Scaling Up
I have to admit – Exchange virtualization is one of my favorite topics. I love talking about it with customers, colleagues, or anyone who will listen. It has a very well known workload profile which makes sizing consistent, it’s virtualization friendly in that it supports vSphere features like vMotion and HA, and I like talking about the challenges and creative…
Where Have I Been?
Looking at this blog over the past 12 months kind of makes me sick. If you ignore posts that have to do with books and a guest blog post by my brother, you’ll see I’ve only published maybe two or three posts all year. That’s very bad, though the explanation for why can be found in those posts. I’ve made…
Great deal on Kindle edition of Virtualizing MS Business Critical Apps

You can grab the Kindle edition here: http://www.amazon.com/Virtualizing-Microsoft-Applications-Technology-ebook/dp/B00E8HSWQU/ I’m a little late in announcing this so hopefully the price stays at this level for a little while.
