In 2008, the year before I left VMware, I was invited to help measure the amount of information being enterprise computers processed in the entire year.  My invitation came from Dr. James Short of the University of California, San Diego, who was on the team leading this project.  The team called their project “How Much Information?” (HMI).  And Dr. Short, or Jim, wanted me to provide comment on a small portion of the systems that process information: enterprise hardware.

The Future of VMware Pricing


Bryan Semple at VKernel last week wrote a blog article on per-VM pricing in VMware and VKernel products. Bryan observed that VMware’s customers dislike per-VM pricing.  He then stated that VKernel will stick to asset-based pricing such as per-socket.

Four Things You Should Know About ESX 4's Scheduler


[This is the last re-post of old community content.  But this content is important enough to be worth a re-post.]

I spend a great deal of time answering customers’ questions about the scheduler. Never have so many questions been asked about such an abstruse component for which so little user influence is possible. But CPU scheduling is central to system performance, so VMware strives to provide as much information on the subject as possible. In this blog entry, I want to point out a few nuggets of information on the CPU scheduler. These four bullets answer 95% of the questions I get asked.
