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.

DELL Enterprise Forum EMEA 2014 in Frankfurt


As you might have noticed on Twitter I was in Frankfurt last week to attend DELL Enterprise Forum EMEA 2014. It was a great conference and very worthwhile going to. It was a week of multi way communication between vendor, marketing, engineering, partners and customers. I learned a lot. And I gave a lot of feedback. As a Dell TechCenter Rockstar and a Microsoft MVP in Hyper-V I can build bridges to make sure both worlds understand each other better and we, the customers get their needs served better.

Dell Enterprise Forum EMEA 2014 - Frankfurt

I’m happy I managed to go and I have some people to thank for me being able to grab this opportunity:

  • I cleared the time with my employer. This is great, this is a win win situation and I invested weekend time & extra hours for both my employer and myself.
  • I got an invite for the customer storage council where we learned a lot and got ample of opportunity to give honest and constructive feedback directly to the people that need to hear it! Awesome.
  • The DELL TechCenter Rockstar program invited me very generously to come over at zero cost for the Enterprise Forum. Which is great and helped my employer  and myself out. So, thank you so much for helping me attend. Does this color my judgment? 100%  pure objectivity does not exist but the ones who know me also know I communicate openly and directly. Look, I’ve never written positive reviews for money or kickbacks. I do not have sponsoring on my blog, even if that could help pay for conferences, travel expenses or lab equipment. Some say I should but for now I don’t. I speak my mind and I have been a long term DELL customer for some very good reasons. They deliver the best value for money with great support in a better way and model than others out there. I was sharing this info way before I became a Rockstar and they know that I tell the good, the bad and the ugly. They can handle it and know how to leverage feedback better than many out there.
  • Stijn Depril ( @sdepril, http://www.stijnsthoughts.be/), Technical Datacenter Sales at RealDolmen gave me a ride to Frankfurt and back home. Very nice of him and a big thank you for doing so.  He didn’t have to and I’m not a customer of them. Thank buddy, I appreciate it and it was interesting ton learn the partners view on things during the drive there and back. Techies will always be checking out gear …

Dell Enterprise Forum EMEA 2014 - Frankfurt

What did all this result in? Loads of discussion, learning and sharing about storage, networking, compute, cloud, futures and community in IT. It was an 18 hour per day technology fest in a very nice and well arranged fashion.

I was able to meet up with community members, twitter buddies, DELL Employees and peers from all over EMEA and share experiences, learn together, talk shop, provide feedback and left with a better understanding of the complexities and realities they deal with on their side.

Dell Enterprise Forum EMEA 2014 - Frankfurt

It has been time very well spent. I applaud DELL to make their engineers and product managers available for this event. I thank them for allowing us this amount of access to their brains from breakfast till the moment we say goodnight after a night cap. Well done, thank you for listening and I hope to continue the discussion. It’s great to be a DELL TechCenter Rockstar and work in this industry during this interesting times. To all the people I met again or for the first time, it was a great week of many interesting conversations!

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://workinghardinit.wordpress.com/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.

image 

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.

Hyper V Amigos Showcast Episode 1: who we are


The very first episode of the Hyper-V Amigos Showcast has gone live. We’ll try to discuss & showcase Hyper-V and related technologies for benefit of all mankind.

In this first episode we introduce ourselves and talk a bit about on the state of our industry and how that relates to our jobs.

Carsten Rachfahl & Didier Van Hoye introduce themselves

Enjoy!

We Need Your Opinion On This Strategy, Vision, Management Issue …


Could you give us your opinion on this?

Lately people, managers, have asked me to give advice or at least my opinion on how to organize & manage IT. In the broad sense of the term. Infrastructure, software, services, support, on premise, cloud, data protection, security …  “Just think about it a bit”.

That question “Could you give us your opinion on this?” is a hard one for me.  I could say “read my blog”, the non technical posts. But my opinion is often too high level and they don’t they actually want that. They want a solution. And it’s not that I don’t think about it or don’t have an opinion. But I can’t focus on areas out of my expertise, my control and priorities.

Basically I cannot help them. Not because I’m that stupid or the matter is beyond our control. It’s because the way managers and organizations think is getting more and faster obsolete by the day.

The Issue

Our world, both privately and work related, is becoming more and more connected every day. That means there is a tremendous amount of input, leading to an ever continuing increase of permutations of ever more variables that come in to play. In short, complexity is on the rise at an enormous rate and will overwhelm us. Even worse is that this complexity only shows itself after things have gone wrong. That’s bad but, that also means there are probably many more relationships of cause and effect that haven’t even shown themselves yet. That kind of sounds like a time bomb.

How do you deal with this? Not in the way so many are asking for. And I’m not here to tell my managers or customers what they want to hear. I’m in the business of telling them what they need to hear as I deal in results, not services or studies. More often than not they are looking for processes and methodologies to keep central control over planning, execution, operations and change. All this while the rug is literally pulled away under their feet. There’s the problem.

Situations, technologies, solutions, frameworks, processes all have a time limited value that’s becoming shorter. So the idea that you can plan and control for many years ahead is obsolete in many areas in our ecosystem. There are just to many moving parts, that are changing too fast. So how do we manage this? What kind of leadership do you need? Well there is no easy answer.

How do I deal with this?

Personally I deal with this by working, collaborating & cooperating in a network, in “the community”. My insights, knowledge, help and support come from my network. Some of my colleagues, the contractors and consultants we hire are in that network. A lot of colleagues are not. Most managers are not. Why is that? They are stuck in a hierarchal world of centralized command and control that is failing them fast. At best they achieve good results, but very slow and at a very high expense. We can only hope that the results also don’t turn out bad. They want procedures & processes. Predictability & consistency but I deal with complexity in wide area of expertise that cannot readily be put into manuals and documentation. Not in a timely fashion. I’m in a dog fight (insert “Top Gun” theme). The processes & logistics provide the platform. Learn where procedures & methodologies work and where they’ll kill you. The knowledge and the skills we need are a living thing that feeds on a networked collective and are very much in flux.  I’m so much more better skilled and effective at my job through participating my global community than I can be tied into the confines of my current workplace they’d be mad not to leverage that, let alone prevent me from doing so. You can’t do it alone or in isolation.

An example

Yesterday was an extreme example in a busy week. I started work at 05:30 AM yesterday to set up a testing environment for questions I needed answered by a vendor who leverages the community at large. That’s required some extra work in the datacenter that I could have done by a colleague that was there today because I found out in time. I went to the office at 08:30. I worked all day on an important piece of work I mentioned in my network and was alerted to a potential issue. That led to knowledge sharing & testing. Meaning we could prevent that very potential issue and meanwhile we’re both learning. I went home at 18:30, dinner & testing. I was attending an MVP web cast at 20:00 PM till 21:00 PM learning new & better ways to trouble shoot clusters. I got a call at 19:10PM of a mate in Switzerland who’s running into SAN issues and I helped him out with the two most possible causes of this through my experience with SANs and that brand of HP SAN.  We did some more testing & research until 22:00 after which I wrote this blog up.

We don’t get paid for this. This is true mutual beneficial cooperation. We don’t benefit directly and it’s not “our problem” or job goal. But oh boy do we learn and grow together and in such help each other and our employers/customers. It’s a true long term investment that pays of day by day the longer you are active in the community and network. But the thing is, I can’t put that into a process or manual. Any methodology that has to serve centralized command and control structure while dealing with agile subjects is bound to fail. Hence you see agile & scrum being abused to the level it’s just doing stuff without the benefits.

Conclusion

This is just one small and personal example. Management and leadership will have to find ways of nurturing collaboration and cooperation beyond the boundaries of their control. The skillset and knowledge needed are not to be found in a corporate manual or in never ending in house meetings & committees. Knowledge gained has to flow to grow As such it flows both in an out of your organization. You’re delusional if you think you can stop that today and it’s not the same a leaking corporate secrets. Hierarchies & management based on rank and pay grades are going to fail. And if those managers in higher pay grades can’t make the organization thrive in this ever more connected, faster moving world, they might not be worth that pay grade.

I assure you that employees and consultants who live in the networked global community will quickly figure out if an organization can handle this. They will not and should not do their managers job. In fact they are already doing managers areal big favor by working and operating the way they do. They are leading at their level, they are leveraging their networks and getting the job done. They are taking responsibilities, they solve problems creatively and get results. It just doesn’t fit easily in an obsolete model of neatly documented procedures in a centralized command and control structure. They don’t need a manager for that, they need one that will make it possible to thrive in that ultra-connected ever changing fast paced world. Facilitate, stimulate and reward learning and taking responsibilities, not hierarchies. That way all people in your organization will lead or at least contribute to the best of their ability. You’ll need to trust them for that to work. If you don’t trust them, fine, but act upon it. Letting people you don’t trust work for and with you doesn’t work.

How to do this is a managers & leaders challenge. Not mine. I know when I’m out of my depth or when not to engage. The grand visions, the strategic play of a company is their responsibility. Getting results & moving forward will come from your perpetually learning, and engaged workforce, if you don’t mess it up. And yes, that is your responsibility. Cultures are cultivated by definition. So if the culture of the company is to blame for things going south, realize you’re the ones supposed to make it a good one. People don’t leave organizations, they leave managers ;-) And to paraphrase the words of Walt Disney … you’re in a world of hurt if they leave you but stay at their desk and on the pay roll. It’s called mediocrity, which also serves a purpose, providing commodities & cookie template services whilst letting others shine. But if you want to be a thriving, highly skilled, expertise driven center of excellence … it’s going to take lot of hard and sustained work and it’s not a one way street.

2014 Kicks Offs With A Microsoft MVP Award Renewal!


I can start of the new year at the office tomorrow by whishing everyone a great 2014 and talking to the CEO about making sure we schedule/budget for the MVP Summit in 2014 as I just got this e-mail in:

image

This is great news. Somewhere this month, a box will arrive at my house with a new ring for the award trophy and a new MVP Certificate. The trophy itself stands proudly on a cupboard in my parents living room. I might have earned the award, but they made sure I was given the little backpack with the values & the education to make that possible. And while they don’t really understand the technicalities of what I do, they think the world of it when I fly of to the USA because Microsoft likes to talk to me Smile.

While you get the MVP award for contributions over the past year to the community you must realize that being active in the community is a very rewarding endeavor in itself. No, it’s not like you can put a hard dollar amount on it, nor want to. The value is that you help out a lot of people and in return effectively crowd source your IT issues to a global community. It help other and yourself learn and grow. We constantly need to figure out a lot of things in our line of business. Studying, thinking, analyzing, designing, implementing & supporting a wide ever changing IT stack is not a one person or one team job. Sharing insights & experiences (both good and bad) with your peers helps a lot. You grow a global network of highly motivated, experienced & skilled people. A network you can leverage & consult when you need it. A network that you contribute to when you can, where you can. That’s what it’s about. The cost of participating is dwarfed by the return as many hand help make hard work easier. Good bosses & smart organizations have figured this out. During a panel discussion at Dell World Jonathan Copeland used the metaphor that it take a village to raise a kid. I added to it that one day that kid needs to leave the village and go out into the world. Being active in communities helps with both. I’ve also talked about this here.

I’m very happy with my 2014 MVP Award. I cherish the interaction with my fellow MVPs and Microsoft. The 2014 MVP Global Summit is already on my agenda. I’m grateful for the opportunities it brings and the continuous privilege of learning & sharing. See you all on line, at conferences, think tanks & community events & in Bellevue/Redmond.
