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…
NLVMUG 2016 sessions

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:

On Friday the 30th of October 2015 I got the great news that I passed the VMware Certified Design Expert (VCDX) defense! What a trip it was! In this blog…
Attending VMworld 2015

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.
