Mapping the VCDX Defense Genome Part 3: Is All Flash a Trap?!

January 5, 2018 Jason Grierson 0

Hey everyone, So prior to the holidays I was helping mentor some new VCDX candidates for their re-defenses and was coming across a few trends that I wanted to discuss a little as they started creeping up over and over again.  These trends were All Flash SAN’s, Oversized Compute, and questions being asked that were not part of the candidates design.  We’ll get into the last point a little more but first lest tackle the first two. All Flash SAN Is All Flash SAN a VCDX trap?  No of course not the All Flash SAN is obviously a silver bullet when it comes to storage as it greatly reduces the complexity of the storage system while giving amazing performance.  Gone […]

Journey to VCIX-NV – Part 3 – Transport Zones, Clusters and Distributed Switches: Relation and Design Aspects

August 22, 2016 Shady ElMalatawey 0

At this point, I started deploying the basic block of any NSX implementation: Logical Switches. Logical Switches are deployed as a virtual distributed port group on your vSphere Distributed Switch (vDS). Logical Switches are deployed within a logical entity called Transport Zone. This Transport Zone can span one or more clusters and single host can’t be added to the Transport Zone. Couple of thoughts jumped to my mind: what is the limit of a Transport Zone? and How does it represent a logical boundary for your NSX implementation? What is the relation between it and both of added clusters and the vDS(es) in the environment? How do all of that affect my design any NSX implementations? To answer my thoughts together, let’s […]

July 5, 2016 Kim Bottu 1

Whether you are a seasoned architect who still is getting familiar with vSphere 6 or a hands-on engineer who likes to get a firmer grip on design and architecture using vSphere 6, Hersey’s updated datacenter cookbook just might be just the book you need. This book graciously keeps a good balance between datacenter design principles, best practices and howto’s. In this book Hersey takes you by the hand and guides you through the steps needed to create a virtual datacenter design using vSphere 6. Besides the necessary theoretical explanations Hersey offers his readers 75 recipes which they can use to help with the creation or optimization of a  virtual datacenter design: What are the prerequisites you need for a design?
