Workshop Datacenter Modernization -Microsoft Technical Summit 2014 Germany (Berlin)

While speaking (What’s new in Failover Clustering in Windows Server 2012 R2) and attending the Microsoft Technical Summit 2014 I’m taking the opportunity to see how Microsoft Germany and partners are doing a workshop which is based on the IT Camps they have been delivering over the past year. There is a lot of content to be delivered and both trainers Carsten Rachfahl (Rachfahl IT-Solutions GmbH) and Bernhard Frank (Partner Technology Strategist (Hosting), Microsoft) are doing that magnificently.

One thing I note is that they sure do put in a lot of effort. The one I’m attending requires some server infrastructure, a couple of switches, cabling for over 50 laptops etc. These have been neatly packed into road cases and the 50+ laptops had been placed, cabled and deployed using PXE boot /WDS the night before. Yes even in the era of cloud you need hardware especially if you’re doing an IT Camp on “Datacenter Modernization” (think private & hybrid infrastructure design and deployment).

Not bypassing this aspect of private cloud building adds value to the workshop and is made possible with the help of Wortmann AG. Yes the attendees get to deploy storage spaces, Scale Out File Server, networking etc. They don’t abstract any of the underlying technologies away, I like that a lot, it adds value and realism.

I’m happy to see that they leverage the real world experience of experts (fellow Hyper-V MVP Carsten Rachfahl) who helps hosting companies and enterprises deploy these technologies. Storage, Scale Out File Server, Hyper-V clusters, System Center and self service (Azure Pack) are the technologies used to achieve the goals of the workshop.

The smart use of PowerShell (workflows, PDT) allows to automate the process and frees up time to discuss and explain the technologies and design decisions. They take great care to explain the steps and tools used so the attendees can use these later in their own environments. Talking about their own experiences and mistakes helps the attendees avoid common mishaps and move along faster.

The fact that they have added workshops like this to the summit adds value. I think it’s a great idea that they are held on the last day as this means that attendees can put the information they gathered from 2 days of sessions into practice. This helps understanding the technologies better.

There is very little criticism to be given on the content and the way they deliver it. I have to say that it’s all very well done. Perhaps they make private cloud look a bit too easy Winking smile. Bernard, Carsten, well done guys, I’m impressed. If you’re based in Germany and you or your team members need to get up to speed on how these technologies can be leveraged to modernize your data center I can highly recommend these guys and their workshops/IT Camps.

The Hyper-V Amigos Showcast Episode 4: TechEd North America 2014

In episode 4 the original Hyper-V amigos (also 4) get together for a chat. Yes, learn about the history of the name and about the what happened at TechEd North America 2014. How Aidan won speaker idol. How I got to be on stage.

Hans is a bit tired but extremely happy due to a certain soccer game outcome Smile. The orange shirt is not by accident. We discuss the keynote, the content, Azure announcements … we jump into one of our favorite topics storage and storage spaces and speculate a bit about vNext timing.

Enjoy!

The Hyper V Amigos Showcast Episode 3: Live Migration

Here’s the 3rd episode of the Hyper-V Amigos show cast. As Carsten was overwhelmed with work (running your own business is very hard work) and had some issues with his storage spaces lab due to testing we’re discussing live migration optimizations in this installment.

 Carsten Rachfahl and I had a lot of fun again, even during the second take, yes we needed one. Apparently these software thingies require me to click on “record” Smile as there is no intelligent agent yet to act on my intention.

Carsten & I discussing & showing some live migration optimizations

 

I have written many blog posts on this subject already and I’m sure I’ll write more. Optimizing the use of the hypervisor (Hyper-V) across the entire storage, compute/memory & networking stack is one of my specialties and I enjoy this part of my job very much. I also like to share this information as real.

I’m sure you’ll agree that Hyper-V has come a long way in short period of time and I’m pretty sure we’re going to see Microsoft continue this pace for quite a while.

I have a blog post coming out (it’s in the queue) on my 4 top recommendations for optimal live migrations but here’s a search of relevant blog posts on this topic, and we referred to some of them during our show cast:

When you’re done reading al these posts on live migration you’ll have earned a nice refreshing beverage of your choice Mug.

One more thing, if you like these show casts let us know! Last but not least, I’m doing a demo heavy (only) session at ITProceed on June 12th 2014. Many local experts, community members  and I will be around afterwards to discuss these technologies.

The Hyper V Amigos Showcast Episode 2: Unmap

We’re back for our second episode of the Hyper-V Amigos show cast. In this episode we discuss and demonstrate UNMAP in Windows Server 2012 R2 a bit. As always it was fun to work with Carsten Rachfahl.

2 Hyper-V Amigos having fun discussing UNMAP

 

Here’s our fun and unscripted (other than the PowerShell used in the demos) attempt at showing you UNMAP behavior with Hyper-V and a DELL Compellent SAN

If you want to read more on our experiences with UNMAP search my blog https://blog.workinghardinit.work/tag/unmap/. I have prepared some links for you.

I still need to get the slides uploaded, but all that info is in the blog posts.

Enjoy!

EDIT:

In relation to the question below about not much difference between Dynamically expanding VHD/VHDX. That demo didn’t work out so well here so I include  some screenshots of a comparison I just ran:

This is the dynamically expanding VHDX. on an IDE controller, no ODX.

This is the dynamically expanding VHD on an vSCSI controller, with ODX.

So yes, losing ODX makes things slower for dynamically expanding VHDX, but it still beats a Dynamically expanding VHD that has ODX.  A VHDX is a lot better at dynamically growing than a VHD.
