I’m Attending The 2013 MVP Global Summit

Well, that time of the year is getting closer again. It’s something different, unique and somewhat exclusive. It’s the 2013 MVP Global Summit!

For this summit MVPs from all over the world converge on Bellevue/Redmond near Seattle. The summit takes place on and around the Microsoft campus. To discuss their favorite & most important MSFT technologies in depth amongst each other and with Microsoft staff.

I have the good fortune of being able to attend again this year. I have to express my thanks to our top management for this Smile. This is very valuable to both me and my employers. It’s also fun to discuss the technology you work with amongst so many like minded people in the same business. The amount of knowledge sharing, insights and ideas around Redmond creates a stimulating buzz and I loved every moment of it last year. I met many great professionals and interesting people with whom, from breakfast till after dinner drinks, we had a truckload of interesting discussions. It’s a bit of a geek fest.

So I’m looking forward to all this and also to meeting up again with some MSFT employees and professionals from the Seattle area I got to know last time.

The MVP summit is also a good time to pass feedback from others on to Microsoft as well. You’re not in the drivers seat when it comes to the direction Windows and Hyper-V will take. However, you cannot have your opinions taken into consideration unless you let them be be heard. So, please feel free to share any remarks, feedback, feature requests you’d like to the virtualization, cluster, storage, file share, network, etc. product teams to know. You can post them in the comments for all to see. To shy to post it publicly? You can send me a e-mail via the contact form on my blog or direct message me via @workinghardinit on twitter.

Now the entire summit is under NDA (Non Disclosure Agreement) but that doesn’t mean it’s a pure diplomatic mission. We all love the technology, that is for sure, but we also  pass along the bad and the ugly next to the good. It’s not marketing or indoctrination,if it was MVPs would not spend the time an money to attend.

That’s where the words “independent” and real world” comes into play. We’re not a bunch of fan boys. The communication is both ways and I think that make this event extra valuable to both parties. I’m looking forward to the 2013 MVP Summit and I have a lot of feedback and questions based on using Windows Server 2012 and Hyper-V in real live.

The Zombie ISV®

The Zombie ISV® is the type that should have been extinct based on the current state of technology. Let me give you an idea what that current state of technology means in our neck of the woods. Last week our team started deploying some DELL R720  PowerEdge servers to replace the last W2K8R2 Hyper-V cluster in the company with a Windows Server 2012 one. The older hardware will be recycled. Some will live on as test servers, backup media servers. All running Windows Server 2012 of course. One of them will become our physical (SAN) LUN to VHDX converter server so we can move our large LUNS (2T-15TB) to vhdx. Later this year 10Gbps networking, RDMA Mellanox cards and ODX will provide for fast vhdx movement to their new virtual hosts. Work in progress, but it should give you an idea about what we’re working with.

It may surprise you but even we have 2 Windows Server 2003 physical servers left. One is a DELL NX1950 Storage server that has been serving local workspace to a team that does image parsing (12TB). That one is >6 years old and is slated for retirement. We don’t need this concept anymore. We can build anything we want for such purposes using Windows Server 2012 Storage spaces and if required leverage the in box iSCSI target. To build it we can just draw disk bays, disk, servers from the retired hardware shelf, no sweat. We have plenty of spare parts and it works just fine. If it’s cost efficient and an effective solution, we roll that way.

The other one is a server for the financial software sold by a company (the Zombie ISV®) that does not believe in virtualization. It’s running code that’s over a 12 years old (legacy java run times and even that was a success because it used to be JInitiator until a a few years ago). There is no life cycle planning what so ever and when after 5 years the hardware needed replacing we got nothing but silence form the vendor. After months of asking for a meeting on the what and how (OS upgrade, x64, virtualization) and being ignored we just took a decommissioned server that had two years of warranty left and transplanted the disks. Even if the warranty runs out on that one we have some of the same model in the spare parts cabinet.

The workload itself runs just fine virtualized but they don’t support that. Luckily for the people that have to do it in their environment they run zero change of that Zombie ISV® ever noticing that a server is virtualized anyway. They also don’t get the concept of a dedicated service account in windows. So they end up with the database or BI services running under their remote support credentials that expire and get disabled by the helpdesk. Sigh. They don’t see the need to proactively support operating systems above Windows XP or browsers after IE 6.0. We did a lot of hacks to keep that system working and came to despise the total lack of technological expertise and professionalism of the vendor. Their “consultants” that’s don grasp x64 bit, or they download installers for 4 hours during a paid day of consulting … sickening to the stomach. Meetings with the account managers (they seem to travel in packs) is a lot of vacant bank stares and apathy. They don’t have answers, they don’t look for answers, they simply don’t care. The idea was to replace the package, but it was not to be. But in the end we settled for throwing all responsibility for it so they’ll find a place to host it and our bookkeepers can access over a secure remote connection. At least we have gotten rid of this security risk in our environment.

That people, is the miserable state of some ISVs in the 21st century. But it’s not just them. It’s a testimonial to the degree in which companies get tied up and locked in to mediocre solutions and technology debt. In the infrastructure world (storage, networking, servers, virtualization) people who know what they’re doing do not allow this to happen. As more and more decisions on software and applications are made by business & analyst types we are seeing an increase in technology debt and lack of any life cycle management. So where we have seen infrastructure get more and more bang for the buck we’ve also seen the software & services cost explode and on top of that incur technology debt, expenses and risks on the business. That’s pretty bad. I see a growing divide in a lot of companies between ever more efficient and cost effective infrastructure (combined with cloud solutions) and the slowness of getting custom software into production combined with issues concerning supportability and upgradeability. All this at ever increasing costs and FTEs. That’s not supposed to happen but it is, despite the high investments in * analysts, business consultants, architects, * coaches, project managers, IT managers etc. in the era of the cloud. This is regression.  It all sounds like the result of the feel good EQ approach to business without results but hey, no one feels left behind Confused smile. I believe a mate of mine calls this the race to the bottom. No wonder some companies that I know have done away with all this and just let business units organize themselves organically. They either fail and disappear of thrive and prosper, but a no time to they fall in to the trap of over organized pseudo flat structure (i.e. pass the hot potato and no responsibility) that still manages to create ever more managerial positions (flat?) whilst realizing ever less results. We’ve seen the financial and housing market charades collapse. Guess what’s next? There won’t be a bail out for you or me, beware of that.

vKernel Adds Tools to Free vOPS Server Explorer 6.3

When it comes to gaining insight and understanding of your virtual environment vKernel has some nifty products. They just added two new utilities, Storage Explorer and Change Explorer, to their free vOPS™ Server Explorer that give you more management capabilities with SCOM/SCVMM or vCenter. Sure it’s to get you looking into and considering buying the paid stuff with more functionality and remediation but it does provide you with tools to rapidly asses your virtualization environment for free as is. So what did they add?

Storage Explorer

  • Gain insight into storage performance and capacity via views across data stores and VMs
  • Identifies critical storage issues such as over commitment, low capacity, high latency, VMFS version mismatch
  • Alerts you to critical VM issues such as low disk space,  latency and throughput issues
  • There’s sorting and searching support

Change Explorer

  • You get a listing of the changes to resource pools, hosts, data stores and VMs within the past week. They also indicate a risk associated with hat change
  • You can search & filter to find specific changes
    • There is a graphical mapping of changes over a time line for rapid reporting/assessment.
    • So if you need some free tools to help you get a quick insight into your environment or the need to be informed about changes of performance issues you can try these out. The press release is here http://www.vkernel.com/press-kits/vops-server-explorer-6-3. We have smaller environment at work next to our main production infrastructure where we’d like to test this out. So they need to add support for SCVMM 2012 SP1 a.s.a.p. I think Smile

      In a world were complexity reduction is paramount and the TCO/ROI needs to be good from day one competition is heating up between 3rd party vendors active in this arena providing tools to make that happen. This is especially true when they are adding more and more Hyper-V support. It also doesn’t hurt to push Microsoft or VMware to make their solutions better.

    Remote File Browsing Issue In Windows Server 2012 Hyper-V Leaves Results Pane Empty Workaround

    In Windows Server 2012 the Remote File Browsing functionality for Hyper-V acts ups on some nodes indicating a problem.

    You can read what “Remote File Browsing” is on TechNet here. You use it to browse the file system on a remote Hyper-V server when creating a  new VM there for example.

    Remote File Browsing is a shell namespace extension implemented by Hyper-V, it provides a way to browse the folders/files on remove Hyper-V server without requiring server to open extra shell over the network.

    The path "::{0907616E-F5E6-48D8-9D61-A91C3D28106D}HYPER-V-TEST" is to tell shell (explorer or common file dialog) that it is hosting/pointing to the RemoteFileBrowsing shell namespace extension on the HYPER-V-TEST. The guid is Hyper-V remotefilebrowsing shell namespace extension GUID. However, due to the limitation on common file browser, it is not able to translated into "Hyper-V Remote File Browsing".

    Now in Windows Server 2012 we sometimes see the following when we use it:

    image

    It seems to work but the result pane remains empty. The cluster is healthy, the nodes are healthy, all nodes are identically configured. Some nodes have it, other don’t. We also can’t find any errors logged anywhere.

    If you try to work around it using the UNC path that will fail due to security issues later so don’t even go there Winking smile

    Basically we were a bit baffled (we could not reproduce it in the lab either) until we saw some posts on then forums, indicating we’re not the only one seeing this.

    http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/608d0c3b-0a7b-4ad9-9843-5e5051dcd526

    http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/7a34f5e1-76bc-493a-8a7a-e9f420bf6a79#d7dd4db7-d7bd-419d-aa72-b12e43cd7a5d

    If you know your cluster is perfectly healthy forget all the security settings stuff and go straight to testing this “fix” or rather workaround: Toggle Audit Object Access on and off.

    In our case I can confirm that these nodes had been under a group policy that audited registry entries during a period that we were trouble shooting network card settings change behavior. We had removed that policy by first reverting the settings to not configured and after some days by removing the GPO. But that didn’t work. Even with no audit policy configured we had to go to all nodes showing this behavior, opening the local Group Policy, toggling our Audit Object Access on for success,applying this and reverting this to No auditing again.

    So fire up an MMC, add a snap-in

    Select Group Policy Object

    image

    Accept the defaults

    When don navigate to Computer Configuration -> Windows Settings -> Security Settings -> Local Policy -> Audit Policy -> Audit Object Access

    Now try to use Remote Browser again (close & reopen all wizard windows and start over a new) to see the results:

    image

    Success! All is well again.

    Notes:

    • We only see this on systems remotely connecting to Windows Server 2012 Hyper-V nodes that are running Windows Server 2012 or Windows 8 themselves not on Windows 2008 R2 or Windows 7 with the RSAT for W2K12 installed.
    • This is not related to Windows core alone due to missing GUI components or something.
