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.

Conferences On My Roadmap For 2014

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.

image

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!

image

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.

Microsoft MVP Summit 2014

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

I’m In Austin Texas For Dell World 2013

This is the night time sky line of where I’m at right now. Austin, Texas, USA. That famous “Lone Star State” that until now I only knew from the movies & the media. Austin is an impressive city in an impressive state and, as most US experiences I’ve had, isn’t comparable with anything in my home country Belgium. That works both ways naturally and I’m lucky I get to travel a bit and see a small part of the world.image

Dell World 2013

So why am I here?  Well I’m here to attend DELL World 2013, but you got that already Smile

image

That’s nice Didier but why DELL World? Well, several reasons. For one, I wanted to come and talk to as many product owners & managers, architects & strategists as I can. We’re seeing a lot of interest in new capabilities that Windows Server 2012 (R2) brought to the Microsoft ecosystem. I want to provide all the feedback I can on what I as a customer, a Microsoft MVP and technologist expect from DELL to help us make the most of those. I’m convinced DELL has everything we need but can use some guidance on what to add or enhance. It would be great to get our priorities and those of DELL aligned. Form them I expect to hear their plans, ideas, opinions and see how those match up. Dell has a cost/value leadership position when it comes to servers right now. They have a great line up of economy switches that pack a punch (PowerConnect) & some state of the art network gear with Force10. it would be nice to align these with guidance & capabilities to leverage SMB Direct and NVGRE network virtualization. Dell still has the chance to fill some gaps way better than others have. A decent Hyper-V network virtualization gateway that doesn’t cost your two first born children and can handle dozens to hundreds of virtual networks comes to mind. That and real life guidance on several SMB Direct with DCB configuration guidance. Storage wise, the MD series, Equalogic & Compellent arrays offer great value for money. But we need to address the needs & interest that SMB 3.0, Storage Spaces, RDMA has awoken and how Dell is planning to address those. I also think that OEMs need to pick up pace & change some of their priorities when it comes to providing answers to what their customers in the MSFT ecosystem ask for & need, doing that can put them in a very good position versus their competitors. But I have no illusions about my place in & impact on the universe.

Secondly, I was invited to come. As it turns out DELL has the same keen interest in talking to people who are in the trenches using their equipment to build solutions that address real life needs in a economical feasible way.  No, this is not “just” marketing. A smart vendor today communicates in many ways with existing & potential customers. Social media is a big part of that but also off line at conferences, events and both contributor and sponsor.  Feedback on how that works & is received is valuable as well for both parties. They learn what works &n doesn’t and we get the content we need. Now sure you’ll have the corporate social media types that are bound by legal & marketing constrictions but the real value lies in engaging with your customers & partners about their real technological challenges & needs.

Third is the fact that all these trends & capabilities in both the Microsoft ecosystem and in hardware world are not happening in isolation. They are happening in a world dominated by cloud computing in all it’s forms. This impact everything from the clients, servers, servers to the data centers as well as the people involved. It’s a world in which we need to balance the existing and future needs with a mixture of approaches & where no one size fits all even if the solutions come via commodity products & services. It’s a world where the hardware  & software giants are entering each others turf. That’s bound to cause some sparks Smile. Datacenter abstraction layer, Software Defined “anything” (storage, networking, …), converged infrastructure. Will they collaborate or fight?

So put these three together and here I am. My agenda is full of meetings, think tanks, panels, briefings and some down time to chat to colleagues & DELL employees alike.

Why & How?

Some time ago I was asked why I do this and why I’m even capable to do this. It takes time, money and effort.  Am I some kind of hot shot manager or visionary guru? No, not at all. Believe there’s nothing “hot” about working on a business down issue at zero dark thirty. I’m a technologist. I’m where the buck stops. I need things to work. So I deal in realities not fantasies. I don’t sell methods, processes or services people, I sell results, that’s what pays my bills long term. But I do dream and I try to turn those into realities. That’s different from just fantasy world where reality is an unwelcome guest. I’m no visionary, I’m no guru. I’m a hard working IT Pro (hence the blog title and twitter handle) who realizes all to well he’s standing on the shoulders of not just giants but of all those people who create the ecosystem in which I work. But there’s more. Being a mere technologist only gets you that far. I also give architectural & strategic advice as that’s also needed to make the correct decisions. Solutions don’t exist in isolation and need to be made in relation to trends, strategies and needs. That takes insight & vision. Those don’t come to you by only working in the data center, your desktop or in eternal meetings with the same people in the same place. My peers, employers and clients actively support this for the benefit of our business, customers, networks & communities. That’s the what, why and who that are giving me the opportunities to learn & grow both personally & professionally. People like Arlindo Alves and may others at MSFT, my fellow MVPs (Aidan Finn, Hans Vredevoort, Carsten Rachfahl, …), Florian Klaffenbach & Peter Tsai. As a person you have to grab those opportunities. If you want to be heard you need to communicate. People listen and if the discussions and subjects are interesting it becomes a two way conversation and a great learning experience. As with all networking and community endeavors you need to put in the effort to reap the rewards in the form of information, insights and knowledge you can leverage for both your own needs as well as for those in your network. That means speaking your mind. Being honest and open, even if at times you’re wrong. That’s learning. That, to me, is what being in the DELL TechCenter Rock StarDELL TechCenter Rock Star program is all about.

Learning, growing, sharing. That and a sustained effort in your own development slowly but surely makes you an “expert”. An expert that realizes all to well how much he doesn’t known & cannot possible all learn.  Luckily, to help deal with that fact, you can turn to the community.
