High Network Utilization on HeartBeat and LiveMigration networks - Windows 2012 R2 Hyper-V cluster

Hi all,
I have just setup a fresh Windows 2012 R2 Hyper-V cluster with 4 nodes.
Config:
Network:
2 x Networks for iSCSI
1 x VM network 1
1 x VM network 2
1 x Heartbeat
1 x LiveMigration
Disks:
5 GB = Quorum
2 x 2.99 TB (Deduplication enabled)
The problem I am getting is that HeartBeat and LiveMigration (both configured with Cluster Only traffic) have alot of traffic on them even though no LiveMigration (the only card configured for LiveMigration) is going on.
All network configuration is the same as it was in Windows 2008 R2 SP1 cluster which these machines where running before (not upgrade, fresh install and migration) and did not have this "problem".
Has anyone experienced this or have a solution to this?
Regards,
Thorir

Hi Thorir,
According to your discription , you can try to monitor and analyse the traffic of LM via network monitor for troubleshooting .
Here is the links for downloading and using network monitor  :

  • High Page Pool Memory Usage on a Windows 2012 R2 Hyper-V Cluster

    Hi, 
    may someone has a similar Problem or can give me a helping Hand. 
    I'm having a 9Node Cluster ( Windows 2012 R2 , fully Patched from RTM Version on ) 
    The Cluster is connected to a SAN which is an Equallogic ( Firmware 6.11).  HitKit Driver 4.7.1 
    The System running clean and without any Event Logs until the Page Pool Usage of the Nodes turn over 15 GB of Paged pool Memory. 
    I monitore that via a Performance Counter ( \Memory\Pool Paged Bytes)
    otherwise I have no indication by for example the Process View, the Calculated Sum on the Overview ( TaskManager / Memory ) but shows on the contraditory the 15GB an Memory Usage. 
    I downloaded the RAMMap Tool from Sysinternals but that doesnt show me any possible Information for the information , acutally the Information differs from RAMMap to the Performance Counter ( RAMMap = 251MB, Performance Counter = 15GB ) 
    Just to make that point clear , there is No Information beside the Sum of Page File on the System Page and the PerfCounter that so much Page Pool Memory is used by any Process . Therefor it is hidden which process "needs" it. 
    I tried many thinks ,  like search for a Memory Hole in the Drivers , Hyper-V Stack , Equallogic and hoped for resolution with any new Patch which had a "Memory Leak" Information to them , but so far none has made a difference , maybe someone
    has the same Problem. 
    My Cluster has routher large VMs on it compared to the Numa Seize ( VM 4-128GB, on DELL R720 ( 2x CPU (8C) 384GB RAM  ) 
    ( The VMs have also a High IO Usage , as there RAM is used as a RAM Database ( zb. Mongo DB ) ) 
    Regards
    M

    Hi Alex, 
    there is something wrong here and not an "normal" Memory Leak , as for that reason I would see the amount of Page Pool Memory assigned to a given Process.
    If that would be the Case I could use RAMMap or even Vmmap to adresse the Paged Pool usage, but those Tools dont reflect the Usage like the PerfCounter does. 
     The Windows Driver Kit for a 2012 R2 System is WDK 8.1 which has a necessity of VS2013 ( Important: Before
    installing WDK 8.1 Update, you need to install Visual Studio 2013. See the Visual Studio links on this page.)  My Last Hope was to get poolmon.exe and identify the Source for the "Paged Pool" Usage .
    We are having that Problem now since the Early Days of Windows 2012R2 and because the Usage is quite "hidden" we only found out , when we ran out of Memory without knowing why. 
    Worst Usage Rates where up to 150GB of Paged Pool  !! given a RAM 385GB ( Dell R720)  that is quite a Number. 
    Im wondering if noone else with a cluster ( seems that the Node numbers in a Cluster and the "RAM" Seize of the VM ( >32GB )  have a tremendous impact on that given Problem , with a 4 Node Cluster the Problem isnt so big )  

  • Make sure your network settings are correct and your network connection is active, or try again later; Have been trying to fix for ages.

    Hi Everyone, been struggling all day to restore my settings on my ipod, as my little brother has put a restriction password in place and made me not able to get into Safari, iTunes, Camera which I really need. I have tried everything, resetting my proxy settings, turning off the firewall, changing my network location, ran diagnostics. Everything seems fine on that, I post below my results. I also tried restoring from the device, but with the restrictions code in place I can not do so. And everytime I am dowloading the software update before the restore it comes up with 'Make sure your network settings are correct and your network connection is active, or try again later'. I have been using google for ages and am not sure what I have missed.

  • IPod Touch 4gen disabled "The iPod Software update server could not be contacted" Make sure your network settings are correct and your network connection is active or try again later.  Please help!

    My daughter forgot her passcode.  Her iPod Touch 4gen is disabled.  I've tried everything I've read online.  I get to the "Restore" part on iTunes and then I get the message, "The iPod Software update server could not be contacted.  Make sure your network connections are correct and your network connection is active or try again later."  How can this be so hard to do?  Why isn't there a simpler solution.  I live 2 hours from the nearest Apple store.  Any advice you may offer would be very much appreciated.

    Update Server
    Try:
    - Powering off and then back on your router.
    - iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
    - Change the DNS to either Google's or Open DNS servers
    Public DNS — Google Developers
    OpenDNS IP Addresses
    - Try on another computer/network
    - Wait if it is an Apple problem

    I am having similar issues except that the store starts to load, then stops, then I only get iTunes Store in gray letters on a white screen. I can access playlist and the other stuff. Like flamesgirl, I contacted them and they just keep sending me links of stuff to try which I had already seen on the Apple website and nothing works. I posted the question on another forum I belong to and one responder said her husband was in an Apple store and asked about this problem as he was having the same issue. They said an update would be coming out soon as they were aware of the problem. Who knows.

    Does anyone know how to solve this tiresome problem, please!?? The update is downloaded upto 723.5MB, and is required upto 723,6MB, then the error message pops out! Tnx.

    I have a quick wifi connection (Mac shows it as about 35 megabits) but I couldn't get the 5.0.1 OTA to work, I had to do it via cable to my computer's iTunes - and as I was already on iOS 5 it was only a small download, basically the same size as the OTA size.
    As the original poster is talking about a 730 meg download then I assume that they are still on iOS 4.3.5 or below and can therefore only download via their computer's iTunes - you need to be on iOS 5+ before you get the OTA option.

    Try rebooting your router and or cable modem. Unplug it/them for about 30 seconds and then plug back in. See if it works then.
    Reboot your iPad as well.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
