I was honoured to be asked to be part of VMware’s CrowdChat for the general sessions this year, the idea being to live-tweet the General Session as it progressed. I’ve tried to embed the session from CrowdChat itself below, but it might be blocked by your browser for running unsafe scripts. You can also see the commentary on the Day One General Session here.

VMware vSAN 2017 Specialist Exam I always like to take a discounted exam at VMworld, this year I opted for the VMware vSAN 2017 Specialist exam, which was released a few weeks ago. Having delivered quite a few vSAN based solutions over the last few years, I was fairly confident in the blueprint. I am pleased to say that I passed the exam with a score of 422, way higher than I expected!

**a non-VMware employee! I am very much looking forward to meeting friends old and new during the week, so if you see me come say hi! Where can you find me? During the day I’m likely to be found in the bloggers area, or hanging around the vBrownbag stage, when I’m not in a session. Monday evening I’ll be leading a fearless team of hackers for the VMware {Code} Hackathon, hoping to create something cool!

Just under two months ago I left my role at Xtravirt and started life as a contractor. At that point I was content to live the contractor life for a year or so and see what opportunities came along. I didn’t expect opportunity to come along so quickly! TLDR; I’m joining VMware as part of the PSO NSX practice! I’ve seen VMware as the place that I would end up working for a while now, having worked as a customer and a partner it seemed like a logical progression.

As a consultant I’ve had the opportunity to design, install and configure dozens of production vRealize Automation deployments, from reasonably small Proof of Concept environments to globally-scaled multi-datacenter fully distributed behemoths. It’s fair to say, that I’ve made mistakes along the way - and learned a lot of lessons as to what makes a deployment a success. In the end, pretty much everything comes down to getting the pre-requisites right.

I’ve been working for Xtravirt for over 3 and a half years now, first as a Senior Consultant, and more recently as a Lead Consultant. During that time I’ve had the opportunity to work with some excellent people, some fantastic customers and some huge projects. I’ve developed and grown as a consultant and architect, achieved multiple VCP and VCAP qualifications, and VMware’s elite VCDX certification. For all of this, and for the opportunities and support they have provided, I am thankful to Xtravirt and to all of my colleagues who helped along the way.

The Host Resources Deep Dive book by Frank Denneman and Niels Hagoort has been one of the most widely anticipated books in the VMware community - previous deep dive books by Frank (co-authored with Duncan Epping), tantalising blog posts and captivating presentations have whet the appetite for the last year or so. Having sat through some of these presentations at VMUGs and VMworld I can tell you the depth and understanding that the authors bring to the table is immense.

With the release of vSphere 6.5, VMware upped the game for vCenter High Availability (vCHA) and introduced an active/passive/witness cluster setup to provide a failover cluster for vCenter Server Appliances. The diagram below shows the architecture of the solution. Deploying vCHA can be done in two modes - “Basic” and “Advanced”. You can use Basic mode if the vCenter you want to be HA is managing the hosts it resides on - in this scenario the wizard configures your vCenter and deploys the Passive and Witness nodes for you.

<img class=“size-thumbnail wp-image-8092 alignright” src=“/wp-content/uploads/2017/04/echo-150x150.jpeg” alt=“” width=“150” height=“150” and having everything wake up for me is really cool. I already have a vRealize Orchestrator workflow to shutdown my workload cluster. What I want to do is trigger that by a voice command from Alexa. Now, the correct and proper thing to do here would be to create a new Alexa skill, write the function in Lambda and connect that to my Orchestrator REST API and execute the workflow.

In this humble consultant’s opinion, Log Insight is one of the most useful tools in the administrator’s tool belt for troubleshooting vRealize Automation. I have lost count of the number of times I’ve been asked to help troubleshoot an issue that, when asked, people don’t know which log they should be looking at. The simple fact is that vRealize Automation has a lot of log files. Correlating these log sources to provide an overall picture is a painful, manual process - unless you have Log Insight!
