Hyper-V 2012 is here and change is good!

On my first blog post about Microsoft Hyper-V R2 which you can find here I received a lot of reactions and I always appreciate it to get any type of response (except the 380 spam comments per day). Most of the people agree with the statements and some don’t. I’d like to start this article with stating that it was not my intention to bash Hyper-V as a product, I really think Hyper-V 2012 is a great hypervisor, it’s the management what is creating the issues.

Hyper-v 2012

So now with the upcoming version of Hyper-V 2012, which will be released as a beta version on the 29th, I’d like to look at what’s changing in regard to my earlier article. Of course the complete hypervisor management architecture consist of Hyper-V and SCVMM 2012.

The focus of this article is (again) mainly on what it means for VDI scenarios however I think that most of the conclusions will go for whatever scenario.

So what’s new in Server 2012, Hyper-V 2012 and SCVMM 2012 and why does it matter!

Windows Server 2012

 

  • Native Dedupping on network and storage

Hyper-V 2012

  • Storage on SMB 2.2 or NFS
  • Live migration without Fail-Over clustering
  • Network revised with true virtual switching
  • Teaming based on virtual switches (just add physical NIC’s)
  • Resource metering

SCVMM 2012

  • No need for clustering now that SCVMM will take care of server placement
  • Live IP based storage vMotion

So how do all these changes make a difference. The best way to show this is by using the picture I created for my earlier post and create a new picture based on the new product features.

The pictures below show the components of a managed Hyper-V platform. On the left the old scenario with Hyper-V R2. On the right the scenario based on Hyper-V 2012.

I hope that the before and after shots make clear that the new features will result in a easier architecture. Less components leads to less complexity and in the VDI case a lot less things that could cause issues.

Conclusion

I can only draw a theoretical conclusion based on the new features because I haven’t tried Windows Server 8 yet.

My conclusion is that with the new features of the different components things will start to change and get better. With the removal of Fail-Over clustering and CSV’s there are just less components which can cause issues.

With the added dedup features and the possibility of live storage vMotion over IP I think that especially for stateless scenario’s we don’t need a shared storage solution anymore. We can use cheap SSD’s for VM placement and when we need to do maintenance we just vMotion the vm’s to another server. I think this will lead to cheaper and easier platforms!

I am really looking forward to Hyper-V 2012 and expect that this will absolutely change the way how I look at Hyper-V in VDI scenario’s. The hypervisor was already great and now the management surely looks mature as well.

    specific issues i hope to see resolved in v.next Hyper-v is the locking issues with CSV that still redirect IO thru parent partition on locking host. that’s not scalable!

    network teaming addresses a core issue Windows has had forever.

    storage and network are the 2 areas I hope to see advancement in Hyper-v 3… those are 2 areas XenServer stumbles and users begin to realize it’s not vSphere. VMFS is undervalued… a clustered FS is a big deal!

    Microsoft has the ability to attract ISV solutions that work with Hyper-v…this is a key area of weakness in XenServer as well.

    Can’t believe I’m saying this but I look forward to the next version of Hyper-v, the hypervisor space needs more legitimate competition.

    I’m working with 2012 SP1. I’m sorry, it is just as painful, if not more than the previous version.
    -The complexity of creating a virtual switch has increased exponentially
    -you still have to always refresh the host/cluster after everything you do
    -you still have to check the jobs tab in ensure your previous action actually was accepted
    -hyper-v mgr is EXACTLY the same
    -failover cluster looks practically the same
    -cluster volumes still just say Volume1, volume2, etc (is that flexible)?
    You will have a mis-match of what a VM is doing vs what SCVMM says (i.e. the famous failed state)
    The list doesn’t stop here!

    So the performance may be there…But, just like 2008 R2, MANAGING IT SUCKS!!!!!

    Folks who continue to say it is great are primarily in pre-sales and don’t have to deal with what Sys Admins have to deal with.
    Unless you want to add an extra few hours to your daily administrative tasks, and add many calls to MS for support (as an early adopter debugger) , tell your rep to screw off when they say Hyper-V is the Sh***
    TRUST ME, YOU WILL BE HATING LIFE LIKE ME!!!!
