I just refreshed my HA Deepdive page. I had it on my “to do” list for a long time but never got to it. Well it took me a couple of evenings but it’s finally done and I’m happy about it. I just hope you guys find the refresh useful and enjoy it. I also flushed all the comments on [...]

Yesterday I posted an article that the required exams for the VCDX certification would be available at VMworld at discounted prices.
