At my day job I am currently working on redesigning our VMware vSphere infrastructure and at one point I had a very simple design that was much like our current design but with newer hardware and putting in vSAN. As fate would have it, our current setup experienced a failure which took 17 hours to get back to normal. This caused me to re-think the design as whole and I started doing some research and stumbled across the VMware Vaidated Design documentation. A few days after discovering this treasure trove of fantastic data VMware released version 4.3 which is based on vSphere 6.5U2 and all the updated components like vSAN 6.6.1U2 and so on.
Why am I telling you about this documentation? Quite simply it is a one-stop shop if you are looking to build a resilient and scalable SDDC which of course I plan on doing now. My 17 hours of fixing our last outage taught me some lessons and the VVD offers up some great solutions to minimize crap like that from happening. Of course nothing is foolproof but this design goes a long way in alleviating some of the issues our original design had. Unfortunately, I had no part in how our current vSphere infrastructure is designed nor do have any real power to push the bean counters to give us money to replace antiquated equipment either but the VVD gives me the necessary firepower to hopefully make an impactful change to how we operate.
The one major selling point is the fact that it covers disaster recovery which is a big deal for us at the moment. Being able to refresh our current setup and setup a DR site is a big selling point. Of course there are some other goodies in the design that will make my life a lot easier for the day-to-day management of the environment.
If you work in the VMware space and are looking at possibly doing a refrsh or a re-think of how your datacenter is designed, I highly recommend giving the documentation a read. Ideally it would be great for a greenfield deployment but how often do any of us get that chance. We typically inherit someone else's design and sometimes they are good and sometimes they are bad. In my instance, it isn't great but I have been slowly making improvements but we have hit a point where something must be done and when I eventually move on to greener pastures, the engineer replacing me will be much happier inheriting a solid design that has been validated by VMware. So wish me luck in acheiving this lofty goal.
