My colleague Eric Gray blogged about “VCritical’s” top 10 this morning and I figured why not do the same… here we go: While many posts from previous years have proven to be evergreen, and among the most heavily trafficked, these are the top posts on Yellow-Bricks published in 2010: ESXTOP VMotion, the story and confessions What’s the point of setting [...]

One of our partners was playing around with vCloud Director and noticed that they could create a Provider vDC and link it directly to an ESX Host. vCloud Director did not complain about it so they figured it would be okay.

It appears that there is a lot [...]

I did not know about this, but someone pointed this out last week and I figured it was worth blogging about as this feature can potentially impact your design. (Think HA admission control policies and resource management) When you create a VM in an Org vDC which is defined as a Reservation Pool you can actually manually set the shares [...]
