Unfortunately the rooms they allocated to my sessions filled up extremely fast.

Project nanoEDGE aka tiny vSphere/vSAN supported configurations!


Advertise here with BSA

A few weeks ago VMware announced Project nanoEDGE on their blog virtual blocks. I had a whole bunch of questions the following days from customers and partners interested in understanding what it is and what it does. I personally prefer to call project nanoEDGE “a recipe”. In the recipe, it states which configuration would be […] Continue reading

Yesterday I tweeted something and I want to reiterate it to make sure that those who are just following the blog, and not my twitter account, also are aware.

The user wanted to remove the datastore from the cluster but didn’t know where these files were coming from and if the VM required those files to be available in some shape or form. I can be brief […] Continue reading

I just wanted to do a short post before the weekend, in vSAN 6.7 U3 there’s a great capacity overview screen.
