Enhanced vMotion Compatibility (EVC) simplifies vMotion compatibility across CPU generations. EVC automatically configures server CPUs with AMD-V Extended Migration technologies to be compatible with older servers. I've created a table with a quick overview about EVC Modes with their appropriate CPU Series and Codenames used by AMD to denote their CPUs.

VMware has launched a new certification exam VCP550 which allows to take the exam based on vSphere 5.5. There is no new certification, you will still earn the VCP5-DCV certification as if you have passed the VCP510 exam based on vSphere 5.0/5.1.

Running ESXi on a Mac mini made by Apple is nothing new. There are many opportunities to consider when you want to build a VMware vSphere Lab or a Homeserver. In this post, I am going to cover capabilities, accessories, and issues you might encounter in the newest release: Mac mini MD387, Mac mini MD388, and the slightly enhanced Mac mini Server MD389 from 2012/2013. Mac mini offers great performance and is small in size and power consumption thus making it a great candidate for running ESXi at home.
The latest version offers 3 models which are different in CPU performance and HDD capacity. The Server version has two 2,5" hard drives:
Part 5, the last part, of the "Manage VSAN with RVC" series covers only one command: VSAN Observer. Observer is a powerful command that gathers performance related metrics down to the physical disks. Statistics can be exported in JSON, saved as HTML or directly viewed from a web browser.
Part 4 of the "Manage VSAN with RVC" series covers commands that are useful to troubleshoot VSAN configurations. The commands can measures performance metrics and fix configuration issues:
