I am joining VMware!

I am incredibly excited to announce that I will be joining VMware! Even more thrilled that I will be a member of the Cloud Platform Business Unit, in the R&D organization, as a Technical Marketing Architect.

Very grateful for the opportunity to be part of a team full of all-stars! My main focus will be my longtime love; VMware vSphere. And everything that comes with it. There is a lot going on with vSphere; version 6.7 U1 is released, we are moving towards the next-gen performance enhancements like PMEM and vRDMA, let alone new (hardware based) security improvements and the recently announced ESXi on ARM support. The list goes on and on…

It all starts with VMware vSphere!!

I thought a lot about joining VMware and kept an eye out for the right opportunity. Even though I was having a good time working as a freelance IT architect with fun projects, the time was right for a new challenge. It all just worked out. Perfect timing.

A big shout-out to all the people who pushed for me, you know who you are! A special thank-you goes out to Emad (Younis) and my fellow Dutchies Frank (Denneman) and Duncan (Epping). Thanks for recommending me. Can’t wait to get started at the end of this November!

See you at VMworld in Barcelona next week!

Clustering Deep Dive Book – released + logo!

Yesterday we finally were able to share the news that our new VMware vSphere 6.7 Clustering Deep Dive book is released.

Countless hours has gone into it; researching, writing content, updating content, discussing a lot, creating the cover designs, creating a logo, having fun!
It was my second time as a co-author after releasing the Host Deep Dive book last year with Frank. I am humbled that I got to work with two of the most regarded individuals in our vCommunity. What these guys did for making the daily life easier for everybody working with VMware solutions, is incredible.

Also, a big thank you to all our reviewers, people who helped realizing this release and Chris Wahl for writing an inspiring foreword.

Clustering Deep Dive

I am a big fan of the previous releases of the Clustering Deep Dive series. When thinking about that, back in 2010-11, the first release helped me a lot to fully understand all clustering constructs. One might say it helped to fuel my enthusiasm for working with VMware vSphere.

Couple years fast forward and here I am working together with Duncan and Frank on the latest release. A big thank you to them for letting me get onboard and be part of this amazing series! As there are a lot of changes since the 5.1 release, we hope this book can help you getting a thorough understanding about all VMware vSphere 6.7 clustering features. The new version of the Clustering Deep Dive covers vSphere HA, DRS, Storage DRS, Storage I/O Control and Network I/O Control. In the last chapter of the book, we bring all the theory together and apply it to create a stretched cluster configuration.

Where Duncan worked on the HA parts and Frank on the DRS parts, I primarily focussed on the Quality Control parts. I feel that these features are often enabled or disabled without really understanding how they can help you managing and enforcing quality control. At least, that is my experience with them. While knewing high-level what NIOC and SIOC are all about, a deeper understanding can lead to new insights on their impact and how to use them. We feel that this addition to the book helps to gain these insights.

Logo & VMworld sessions

The idea is to provide you with a vSphere Resource kit to fully understand all features from the hardware components and everything involved all the way up to the vSphere clustering service on top of that.

Host Deep Dive book + Clustering Deep Dive book = vSphere Resource kit

The following VMworld sessions are all based on the Deep Dive series:

  • vSphere Clustering Deep Dive, Part 1: vSphere HA and DRS [VIN1249BU]
  • vSphere Clustering Deep Dive, Part 2: Quality Control with DRS and Network I/O Control [VIN1735BU]
  • vSphere Host Resources Deep Dive: Part 3 [VIN1738BU]

Now the Host Deep Resources Deep Dive, Part 3 might be a slightly confusing title. It is part 3 because we already did Part 1 at VMworld 2016 and Part 2 in 2017. We will bring a new awesome way of delivering host resources knowledge in that session. More on that later.

With the arrival of the new Clustering Deep Dive book, we came up with a new logo to accompany the Host Deep Dive logo. There will be a limited number of shirts + stickers (pushing for on-time delivery) that we will bring with us to VMworld. We will give some away in our sessions so make sure to attend!

NLVMUG 2016 sessions

This March the 17th, the annual NLVMUG UserCon will be held in ‘s-Hertogenbosch. Last year an amazing turnout  of 900+ attendees was reached! It turned out to be one of the largest VMUG world wide. Let’s top that this year!

Make sure you don’t miss out and register here!

NLVMUG

It’s gonna be a full agenda with around 23 sessions divided between VMware, sponsor and community speakers. Next to that there’s  also the boot-camps and 2 keynotes. Speaking at keynote 1 will be VMware’s own Kit Colbert! You can use the breaks to have a look at all the stands. Be sure to talk to as much interesting vendors as possible. Hear them out on what they could bring to your IT challenges.

It will be an action packed day. One could say the NLVMUG is starting to look like, a sort-off, mini VMworld.

Rutger and myself will be there, presenting in our own VMUG community sessions. Check out our time slots:

My VCDX experience

Friday the 30th of October Rutger and myself got the great news that we both passed the VMware Certified Design Expert (VCDX) defense! What a trip it was! In this blog post I would like to take you through my experience of the whole process…

VCDX-DCV

For the ones not familiar with the VMware VCDX program, here’s a quick introduction…

VCDX-DCV requires enterprise-class vSphere and data center virtualization skills. This elite group is comprised of design architects highly-skilled in VMware enterprise deployments The program is designed for veteran professionals who want to validate and demonstrate their expertise in VMware technology.

Certification is achieved through the unique design defense process, where all candidates must submit and successfully defend a production-ready VMware Solution before a panel of veteran VCDX holders. This process ensures that those who achieve VCDX status are peer-vetted and ready to join an elite group of world-class consulting architects.

All in all it is a pretty time consuming track which goes back to the days where I was learning for the VMware VCP5-DCV certification. After that I went ahead and aimed for both VCAP5 certifications (soon to be replaced by the VCIX exams). Just about a year ago, I actually decided to step it up a notch and go for the pinnacle of VMware certification being VCDX!

However, It did take me up to 6 months to actually start with my application. If I would do the whole thing again, I would definitely started way earlier with it than I did. Oh well, once up & running I managed to stay focused and put in the effort required.

I’ve talked to a fair amount of current VCDX holders over time and always knew I wanted to be part of this. I wanted to know if I could do this. What was the worst that could happen, right?! To fail perhaps? Then I would go for a second chance. No shame in that.

Attending VMworld 2015

This August Rutger Kosters & myself will attend VMworld 2015 US where we will represent our employer YaWorks. We will fly in a bit early (on Wednesday the 26th of August) to check on the Valley before we will head to downtown SFO. We will hook up with a (near) local who is quite familiar with the Valley and SFO surroundings. 😉


Update 1: Our befriended near local inhabitant (Frank Denneman) arranged visits to some of the most interesting vendors out there. We will meet-up with the clever minds of the following vendors in their HQ prior to VMworld!


Flights booked, straight from Amsterdam to San Francisco. Some pretty cool residences booked in Palo Alto (first few days) and SFO. Gotta love Airbnb! Ford Mustang > check!!
Needless to say we are pretty damn pleased, to say the least, with the support from our employer who made this all possible for us. 😀

vmworld2015-sfo

Cloudfix colleague Robert Verdam will, almost certainly, attend VMworld 2015 EMEA in Barcelona. We will try to make it to Barcelona also… Time will tell.


Update 2: Robert and myself are among the few of many vExperts to have received a blogger-pass by VMware for VMworld Barcelona!! Rutger will wander the streets of Barcelona during day hours and will be available for dinner and parties! 😀

VMware Virtual SAN 6.0 benchmark

Last week I was going through ‘What’s New: VMware Virtual SAN 6.0‘, it seems like VSAN 6.0 is bigger, better and faster. The latest installment of VMware’s distributed storage platform provides a significant IOPS boost, up to twice the performance in hybrid mode. The new VirstoFS on-disk format is capable of high performance snapshots and clones. Time to put it to the test.

 

Disclaimer: this benchmark has been performed on a home lab setup, components used are not listed in the VSAN HCL. My goal is to confirm an overall IOPS and snapshot performance increase by comparing VSAN 5.5 with 6.0. I did so by running a synthetic IOmeter workload.

VMware has a really nice blogpost on more advanced VSAN performance testing utilizing IOmeter.

 

Hardware

My lab consists of 3 Shuttle SZ87R6 nodes, connected by a Cisco SG300.

 Chipset  Z87
