VMUG in Copenhagen february 19th.

This years VMUG in a cinema is about NSX, and features sessions from customers that are using NSX and some that are contemplating it. VMUGdk has also scooped Martin Casado to come and speak. Martin is the co-founder of Nicera, the company that VMware bought to rename it to NSX.

I will try to give a recap of the day below.

First up was a customer session with Michael Munk Larsen and Thomas Raabo from Zitcom, talking about their transformation from “normal” networking to Software Defined Networking.


A very honest accounting of their experiences with NSX and all the issues they have encountered working with the first versions of the product, and why they don’t run NSX yet. Ended up sounding a lot like an NSX bashing session, but they kept pointing out that all the nice things about NSX can you read on different blogs.

Next up we had a very enthusiastic presentation from Martin Casado,
Starting out by giving a background story on Network virtualization .


Next moving on to showcasing different use cases for network virtualization: automation and micro segmentation.


A very interesting session with good points about network virtualization, and very nice work by the VMUGdk team to get Martin to Denmark

The next speaker was Christer Swartz of Palo Alto Networks, formerly of Cisco and Netflix. Doing a presentation on Palo Altos views on NSX and on software defined networking. Talking about what Palo Altos firewall can do for you.

Also talking about Dynamic Address Groups, and how that works with NSX


Making a point about having both the physical and virtual topology be both managed by Panorama, their management software, and them being aware of each other.

Not that big, a company in Denmark, but does seem to have some really nice features.


The last session is a community session, by Stefan Pahrmann from Lego


Talking about their reasons for buying NSX, and their plans to implement the software. Their main reasons are security concerns when expanding in both Asia and USA. Another big reason for their purchase was the automation part of NSX. Both very good reasons, and the much of the same reason I will consider an NSX installation

A very nicely done 5 slides presentation.

One of the points was stating that software was better than hardware always… Have to Quote Signoutdk on this one.

“I still prefer my LEGO to be hardware no matter what they say!”

After this there were a few price draws, and we finished off with watching the movie Kingsman, the secret service.

As a nice joke, Liselotte (VMUGDK leader), had the cinema start the movie 50 Shades of Grey instead, leaving 250 males bewildered 🙂



Thank you VMUGDK for a nice day.

vExpert 2015



So the list is out, and I’m very honoured to be named vExpert again. I must admit that I was bit worried this year 🙂

Looks like a few new Danish members of the vExpert team.

Check the list here:


vSphere 6.0

So it’s finally here!
The long-awaited release of vSphere 6.0, has been released, and will ready for download medio March we’ve been told. I’ve done a small write-up of some of the new features in this release.

Release cycles
As seen at VMworld, where many customers thought that VMware would release vSphere 6.0, VMware has adopted a strategy of longer release cycles of the core component vSphere. So instead of a yearly release we are most likely to see roughly 18 months release cycles instead. This is because the hypervisor needs to be stable all the time, and not something you’d need to upgrade all the time. On the other hand products like vRealize Operations or vRealize Automation Center will see shorter release cycles. I’m really liking this approach, as the hypervisor really is in the center of your data center core, and as such we need the absolute most stable product here.

Multi-processor Fault Tolerance
We’ve seen multiprocessor Fault Tolerance demoed at a few VMworlds so far, but now finally it’s here. with vSphere 6.0 you can now have Fault tolerance on VM’s with up to 4 vCPU’s. This finally opens up for the useful Fault Tolerance VM’s. I haven’t seen many critical VM’s with only 1 vCPU, even vCenter Server needs more than 1, so the use cases for the old Fault Tolerance were few and far apart.
A lot of older applications, haven’t been built with High Availability in mind and for this FT comes into play, and with the new 4 vCPU limit a lot more of older applications can be protected by FT as well. I’m guessing a lot of costumers will use this feature in their data centers. However the Bandwidth requirements for this will be quite steep, so cross data center FT might not be feasible just yet :). As with the old FT this won’t save you if your application corrupts, then both instances will be corrupt. For this you really need applications that were built for High Availability in mind.

Inter vCenter vMotion
This I think is one of the biggest new features of vSphere 6.0. The ability to vMotion between 2 vCenters is one thing a lot of people have been looking for, for a looong time. Moving VM’s without downtime to a new vCenter with newer vSphere, wasnt that easy if you deployed distributed switches. But now that really should be a thing of the past. A whole new set of design architectures should be set up now because of this feature.

Long distance vMotion
Another really nice new feature is long distance vMotion, where before you were limited to 5ms latency or 10ms in Enterprise+, you can now vMotion across links with up to 100ms of latency. For us Europeans that means we should vMotion vm’s across borders to neighboring countries or at last across the country. This opens up quite a few new scenarios for highly available infrastructure. In Denmark fx. we could vMotion between Seeland and Jutland, which would solve some of the Power issues we have :).

Web client
The last thing I will write about is the client. The new Webclient is much improved over the previous ones, and both looks and feels more like the C# client, which still is available in vSphere 6.0. Unfortunately its still not in HTML5, which would have been preferred, so the webclient could work on OS’s



The wait is almost over!

This is an exciting week. Tonight VMware starts their 28 days of February Launch, so keep a lookout for that. 6.0 does bring some exciting new features.

This week is also the week where the first batch of 2015 #vExperts should be revealed. I’ve send an application, and fingers will be crossed. Hope to see a lot of fellow #VMUG’ers on the list.

Have a nice and hopefully exciting week!
