"Attending VMworld 2018 Europe? Come talk to my colleagues and I at the Expert Bar."
Do you mean the icon "vExpert" on the top of this page ?
This refers to the VMware Experts Bar at VMworld Barcelona (e.g. VMware employees from different SMEs answering questions/talking to attendees).
I (Paul Twomey) and my colleague Kamil Zapert will be manning the vSAN area for the duration of the event.
Do you plan to provide a website (tchat) to discuss on VMware subjet though Internet ?
I can't travel to Barcelona.
At the end, and without any SSD Drive on our servers, the vSAN can't be enable, and the vSAN Witness is not still necessary.
Maybe, in few months, we will bought these SSD Drives for ou servers, and we will able to enable the vSAN.
Or maybe, we will buy a SAN.
Then SSD Drives are mandatory for vSAN.
