vSAN Design Considerations

I have gone through the vSAN 6.2 Design and Sizing Guide, the vSAN 6.2 Network Design Guide and the vSAN 6.2 Stretched Cluster & 2 Node Guide (230+ pages) and aggregated all of the design decisions, design considerations and best practices into one page of bullet points that is easy to consume.

Baby Dragon Triplets – VSAN Home Lab

vcdx133 Allow me to introduce Drogon, Rhaegal and Viserion, my three host, “VSAN Baby Dragon” Home Lab.  Straight from “Game Of Thrones”, if you are wondering what the names mean.  I finally bit the bullet and invested in some new kit to move away from the limited Embedded ESXi lab I was running on my MacBook Air.  I sourced everything from the Computer Souq in Riyadh, since I did not want to wait for shipping, which can be expensive.  I have provided the details for anyone who wants a vSphere lab that works without the head scratching.
