As if 2016 weren't bad enough...this year is going to be slightly longer than normal. New Year's Eve will be one second longer in 2016 to adjust for the shifting rotation of the Earth. A leap second is a one-second adjustment that is sometimes applied to Coordinated Universal Time (UTC) in order to keep its time of day close … Continue reading 2016 takes a leap…a leap second
I’m pleased to announce that a book I recently co-authored is now available for purchase. You can find it on the Amazon or Packt Publishing sites.
I had the opportunity to take the VCAP6-DCV Deploy (Beta) exam last week. The beta is still ongoing and costs $100 (regularly $400). A few notes: It’s HOL based (HTML5 rather than RDP) so performance has improved quite a bit. But as expected, the vSphere Web Client is still quite laggy.

Each virtual switch on hosts running ESXi 5.1 and earlier provides a finite number of ports … Continue reading Standard vSwitch Port Scale
Quick review of TPS: Transparent Page Sharing allows pages that are identical to be stored in same place. When there is idle CPU time, vSphere looks for pages located across virtual machines that can be matched with one another and shared in physical RAM. This is basically a deduplication method applied to RAM rather than storage. … Continue reading Transparent Page Sharing (TPS) Changes
VMware released vSphere 5.5 Update 2 on Tuesday, September 9. You can find a summary of fixes here. I’d like to point out one of the changes: “Unable to edit settings for virtual machines with hardware version 10 using the vSphere client When you attempt to perform the Edit Settings operation using the vSphere Client (C# Client) … Continue reading vSphere 5.5 Update 2
