Back in March, I shared a presentation with Duncan Epping during the NLVMUG. This VMUG is one of the biggest and oldest VMUGs in the world. I presented the current state followed by Duncan, who is very well positioned to cover all the things that are still work in progress. A month ago the NLVMUG Usercon published the presentation video on YouTube. Enjoy this presentation.
Over the last couple of months I had been involved in the development of the ‘DCIS-Cube’, the new architecture that will be used as a ‘portable’ and easy deploy-able system by NATO’s Communications and Information Agency (NCI Agency). Portability and the ease of deployment of infrastructure in regions of deployment have always been challenging for the NCI. When they have to deploy a small datacenter to support a mission somewhere on the globe, they have to ship a couple of racks with hardware to that specific place. Apart from the logistical nightmare of moving a ton of hardware, they are struggling with the actual deployment of all that hardware as well. As every single mission has different requirements they can’t prepare the solution somewhere […]
VMware launched a new HCI assessment tool. Last week Duncan Epping reached out to me. He had a customer asking him if he could have a look into the environment so they could better size the environment with VSAN. I got in contact with the customer on Friday and on Tuesday we had a call in which we discussed the whole environment. Even Mister Epping is impressed with it. Customer reached out a week ago, wanted to know if vSAN would be an option for them. Connected them with @sdepril and within 3 days a full report was produced using the new VMware HCI Assessment tool. It is really powerful!

There’re a lot of blog posts and videos out there of people describing their path to the VCDX. They’re all good reads/views and you can glean some valuable information out of them. What hasn’t been done enough of is how you shouldn’t do this, where people tripped and what they learned from the process. After all, it’s the “I did it..” posts that make music. This post describes some bits of my journey towards this credential and more importantly, I’ll make an attempt at telling you what I did wrong or not enough of or too much of. Given the VCDX is about real world designs too, this post might be helpful in everyday jobs. Before anything else, I’ve got […]
Part 3 of this series will go over the oft overlooked design scenario. My advice with scenario is to (while keeping in mind I haven’t achieved the number yet): Listen carefully and keep prying out information from the panelists. They’re playing the role of customers, sometimes difficult customers. Maybe one of them won’t speak at all only to throw that wrench in when you’re about to clinch it. Watch out for that silent panelist 😉 If that wrench is thrown, tell them you’re going to erase a certain section of the whiteboard because the information you wrote on there is now irrelevant because of a changed requirement or a new constraint you’ve discovered as a result of that wrench. Make […]
This post will cover those bits where I messed it up. In case you missed Part 1 of this series, check it out here. So in no particular order: Insufficient technical depth This might be a strange one to some, especially the people just starting out on this path. You’ll likely hear – keep your presentation at the logical level – by a lot of people. This is true for the most part and you should absolutely avoid getting tangled in a time-wasting explanation of say how multi-NIC vMotion works. Instead focus on how this decision fulfilled a business need (things like minimizing maintenance windows etc..). But.. I realized after the first two attempts the panelists were prodding me for […]
For quite some time I have been thinking about setting up a new virtual VSAN lab on Ravello and Oracle Cloud Infrastructure, aka.: OCI. There is not better time to get things done than the present, especially since vSphere 6.7 and VSAN 6.7 have been released earlier in the month. First: a big thank you to Ian Sanderson and Raff Poltronieri for posting to get vSphere 6.7 to work on Ravello / Oracle OCI. You can read about that right here. However, I was not really pleased with the network setup on my hosts. For starters, all my interfaces had been put on the same network, both the MGMT vmnics and the VSAN vmnics. I decided to change this. Starting today, […]
This past weekend I sat for and successfully passed the VCAP6.5-Design exam. It was great to finally pass an exam on the first go (I’ve had a torrid run recently, that’s going to be another post on its own). Here’re some details about the exam environment, my experience and suggestions for future takers. Exam center: When booking the exam I needed to find a center that offered exams on the weekend. Turns out Aviation Training Service Victoria in Airport West was the only one that offered Saturdays and Sundays. I booked an 8am appointment for the exam, I thought I rocked up nice and early at about 7.40, lo and behold the parking was full as. The center also offers […]
