DellEMC World 2017 – Conference Recommendations

DellEMC World 2017 – Conference Recommendations

This will be my 2nd year attending DellEMC World and I wanted to give my perspective on what to expect and some recommendations on attending.  There are several different key pieces to the conference, each with a different set of value.

Breakouts – There are 3-5 per day with Thursday being a session only day.  These are good for server different reasons.  The first breakouts on Monday will have something new to announce, which is always exciting.  These breakouts will have product owners and some super smart minds presenting on their technologies.  Some of the Breakouts also outline best practices and go into deep dives.

General Sessions – Monday thru Wednesday there is a general session starting at 10am and lasts until Lunch.  These are always well done and should be attended.  This year you will see Michael Dell, Jeremy Burton, Jeff Clarke, Pat Gelsinger, David Goulden and Chad Sakac.

Solutions Expo – This is self-explanatory.  Showroom floor where all the Sponsors and Vendors have their booths setup.  Always a great place to network and a lot of value can be had here.  Also, SWAG!!

Free Exams – DellEMC exams are free on the first try for each one.  Take advantage of this.  By visiting the Proven Professional area you can also pick up some nice swag.

Entertainment – This is Vegas, there is plenty of entertainment.  The conference offers a Grand Opening Reception in the Solutions Expo on Monday, a Happy Hour on Tuesday, and the Appreciation Event on Wednesday.

Travel – Highly recommend arriving on Sunday.  You don’t want to miss the start on Monday and it gives you the opportunity to network and meet with people you may only see once a year.  Last year I left early Thursday. This year I am leaving Early Friday.  The reason is that Thursday is a day dedicated to Breakouts and it’s the perfect opportunity to make up for any possible breakouts you may have missed.  You will find that you make a plan for each day and it changes as things arise.
