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.

Speaking At The ITPROceed Event–June 12th 2014, ALM Antwerp

The Belgian IT Pro community is organizing the ITPROceed event a “technology geek fest” as they call it on their web site.

image

It’s a joint venture between the IT pro community and Microsoft Belgium to help you all proceed in designing, deploying and operating Microsoft technologies.

The sessions will not only help you proceed but succeed as well. The speakers are Microsoft MVPs, MEET members & passionate community experts. They’ll share expertise & information gather by using these technologies in real life deployments.

A rich mix of technologies you have available and need today will be discussed like the Cloud OS, System Center, SQL, Office 365, Windows 8, Unified Communications, Lync, Azure and SharePoint.

I’m speaking

I’ll be speaking about the features in Windows Server 2012 R2 that make it “The Scalable & Capable Cloud OS”.

Come see how you can leverage the capabilities of Windows Server 2012 R2, a true cloud OS, to achieve powerful and scalable solutions. We’ll demonstrate how to use technologies as SMB Direct, DVMQ/vRSS, ODX, UNMAP, VHDX and Storage QoS. This will help you get the most out of commodity infrastructure and investment in Windows today.  We’ll share our experiences with you based on real life deployments to help you proceed and succeed.

Join us!

Really, make time in your schedule and attend this event by registering here.

Attend the sessions, talk shop with your peers and discuss your questions with the experts. I’ll see you there.

Here’s a little roadmap of conferences on my radar screen for 2014. Some I can’t attend because of conflicts in my schedule and other priorities, but I list ‘m here for your consideration.

DELL Enterprise Forum

If you’re working with Dell technologies, either hardware or software this is for you. It very interactive and you get provide feedback to the product teams as well as briefings on what coming. Some are under NDA, some not.

TechEd North America 2014

I’m attending, everything has been arranged. So if you’re a blog reader/twitter follower give us a ping.

E2EVC 2014 Brussels

This is a non marketing event by experts in virtualization. So these people design, implement and support virtualization solutions for a living.  E2EVC Virtualization Conference is a non-commercial, it does not run a profit for the organizers or speakers. Everybody volunteers. The attendance fee covers the costs of the conference rooms, coffee breaks and such. The value is in the knowledge sharing and the networking.

OSCON 2014

I love watching the OSCON presentations on line and it’s one of my never attended that on my must attend list. Whether that will happen this year remains to be seen.image

TechEd Europe 2014

It runs from October 27th to October 31st 2014 in Barcelona. I hope to meet you there and I hope they are ready at that time to talk about vNext Winking smile. It’s a great opportunity to network and talk shop with so many of my peers I’ll most definitely try to be there. Any vNext information would most certainly make it a not to miss event. They announced it a bit late and they already have lost some of the potential attendees to TechEd North America. Not their best move ever I must say.

E2EVC 2014 Barcelona

Details have yet to be announced. But if my schedule allows I will attend and present!

Dell World 2014

No details as of yet but for partners & customers this is a valuable opportunity to talk to the product teams, directors, marketing mangers and engage in some serious conversation about technology and where DELL fits in your road map.

I will NOT miss the MVP Summit Smile. No details as it’s all NDA.
