Does Hyper-v HA need shared storage?

I have a server running Hyper-v 2012 server. On this hyper-v host I have 1 DC and 1 DHCP server running. I don't worry too much in regards to fault tolerance with these servers. I have two other DCs running on physical servers and if DHCP goes down, it only
takes minutes to install DHCP elsewhere.
My company is now looking into virtualization and would like to start virtualizing more servers, servers that are critical and does need some type of HA and/or FT.
We are a SMB (~20 servers. mostly server 2008) company. For our most critical server, the longest it can stay down is 1 hour. So our recovery time should be less than 1 hour.
With all this said, what would you recommend in terms of building a virtual environment. Would using hyper-v replica be enough or would HA have to be implemented? If HA is implemented, and I imaging that the hyper-v hosts need to be in a cluster, would we
need shared storage (SAN) in order to use HA and/or FT?
Please let me know if you need more information.
Best regards,
Alex

I would recommend using a cluster setup for High Availability. Of course, that would require a shared storage. Ideally, you need to have a SAN for its performance. However, with Hyper-V 2012 and higher you can use SMB 3.0 for the shared storage instead.

Of course, it remains better to have a replica too if this is possible.

  • Using Firefox v. 19.0.2, what does the feature (Move to shared storage) do?

    I am trying to save my stored bookmarks and Logins, hopefully saving them when I upgrade Firefox.

    To be clear move to SD card only moves the Firefox application files.
    It is not possible for a normal user to access the Firefox for Android profile. If you have a rooted phone you can find the profile in

  • Migration/Live Migration fails with shared storage (SMB), but not all the time

    I have 2 Hyper-V Hosts using shared storage via SMB. I'm having intermittent issues with migrations failing. It'll either go through the motions of doing the whole move and fail and/or when I try to start it again I get the following:
    I've done a lot of reading on this and have done various things that have been recommended. For each Hyper-V host I've setup delagation via Kerberos. ie. HV_Host1 has CIFS - HV_Host2; CIFS - SMB Server; MS Virtual System Migration Service - HV_Host2 and
    vice versa.
    On the actual SMB share on the Shared Storage server I added permissions to the folder for HV_Host1, HV_Host2, Storage Server, Domain Admins and my user account for full access.
    In Group Policy, I've blocked Inheritance for the OU containing the Hyper-V hosts, though I have added some of the Group Policy's manually that I needed.
    Last thing, I also added Domain Admins to the Local GP on each Host for "Log on as a Service" and "Impersonate a client after authentication" as shown in this thread: http://social.technet.microsoft.com/forums/windowsserver/en-US/7e6b9b1b-e5b1-4e9e-a1f3-2ce72ea1e543/unable-to-migrate-create-vm-hyperv-cluster-2012-logon-failure-have-to-restart-the-hyperv
    I get these failed migrations regardless if I start them on the actual Host or via the admin console from Win8.
    At this point I'm not sure what else to check or the next step to take for this.

  • Clustering without shared storage

    Is there a way to cluster two Sun Fire 280R without a shared storage?

    Not so sure on the argument there... The 'Sun Cluster Overview for Solaris OS' document (available on docs.sun.com) clearly states on Page 9...
    'A cluster is two or more systems, or nodes, that work together as a single, continuously availble system ...'
    Thus you can have a two-node cluster. To do so, however, you would NEED shared storage to configure the Quorum device. This device is, essentially, the third vote. In a split-brain situation, where interconnects have failed and both sides of the cluster think they're the only node active, the Quorum device is used to determine which node stays in the cluster. This was historically done by all nodes racing to place a SCSI reservation on the nominated Quorum device. The node which fails this would panic, instigated by the failfast driver, to ensure data integrity. How it is actually done now I'm not quite sure, but there is still a race for quorum by all nodes (p.22 Sun Cluster Overview). Thus the Quorum device is required for a two-node cluster, and the cluster would not fail completely in the event of a single node failure.
    Hope this helps

  • The storage where the virtual hard disk is located does not support virtual disk sharing

    Hi everyone,
    I deployed 2 hyper v vitual machines a while ago, and i did that because I needed to test my current game Project, which is an
    online game. However, i've had some problems with my Windows installation then I had to reset the pc by making it a refresh
    install. I still have the hyper v virtual disks, but i cannot attach it to a new hyper-v virtual machine. it pops up this message:
    "the storage
    where the virtual hard disk is located does not support virtual disk sharing". I dont know anything about virtual machines, so I
    didnt know I had to make the disk sharable. How can I force to attach the hard disk to a new hyper-v? I dont want to go t
    hrough the whole proccess of installing the operating system all over again and updating it....
    Any help is greatly appreciated!
    Thanks in advance,
    Romulo Romero

    Hi MrDebugging,
    >>
    When I Try to add a SCSI Controller, and then I click browse to add a UNC I get this:
    C:\Users\Public\Documents\Hyper-V\Virtual hard disks\ClienMachine.vhdx
    but I tried placing in different location, and the same problem occurs!
    By the way, Im not on a server , I am a domestic user and I am running it on my
    Windows 8.1
    According to the error message , it seems that it is not a permission issue .
    The VM is Gen 1 or Gen2 ?
    Generally the error message occurs when you enable "shared vhdx" on standalone/client hyper-v host :
    Please try to attach the VHDx file to IDE controller if it is a Gen 1 virtual machine (because only the SCSI controller has the option "virtual hard disk sharing" and Gen 1 VM only can boot from IDE )
    All in all , please do not use this feature without CSV or Scale-Out File Server with SMB 3.0 on file-based storage .
    If it is not the case , please detail steps what you did .

  • My host name changes every few days, since Xmas adding a macbook its changed 6 times. Do I need to stop this? Does it cause problems with sharing between the iMac and macbook?

    my host name changes every few days, since Xmas adding a macbook its changed 6 times. Do I need to stop this? Does it cause problems with sharing between the iMac and macbook?

    There are several possible causes for this problem.
    1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local".
    2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
    3. A Mac wakes from sleep due to network traffic. This is due to a bug in OS X that may only affect some models.
    4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
    5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.
    6. See also this support article.
    Rename the computer in the Sharing preference pane.

  • HT4352 Lost my remote to my Apple TV and I can not turn on home sharing w/o it.  Does this mean I need to purchase a new apple Tv

    Lost my remote to my Apple TV. Downloaded the remote app to my iPhone but you need to have home sharing turned on the Apple TV to use this. Does this mean I need to purchase a new Apple TV?

    Any code association only applies to 1st gen Apple TV.
    Again, the remote app will need home sharing enabled on the APPLE TV. They also need to be on the same wifi network. The OP has a new network.

    Hi
    Thanks for that. Yes, the ipad was purchased recently. I called Apple last Friday and they ask for the receipt. I wonder if anyone were able to swap their ipad for a larger storage in the past at the apple store without a receipt? 16Gb is such a small storage.

  • My phone told me it needed more storage - especially to update my iPhone iOS.  I decided to as more per month. It's still telling me it's almost full and I can't update. What am I doing wrong?

    My phone is telling me it's almost full. Also I have and update to the phone that says I don't have enough storage. I updated this month to a lot more. It's still telling me I need more storage. I don't understand.

    Ok and thank you. I did delete a LOT of photos and moved all my music just into my icloud and got rid of apps - really cut it down. i tried deleting music from my library and it won't let me and I have this update thing and I'm not sure what to do.

  • DFSr supported cluster configurations - replication between shared storage

    I have a very specific configuration for DFSr that appears to be suffering severe performance issues when hosted on a cluster, as part of a DFS replication group.
    My configuration:
    3 Physical machines (blades) within a physical quadrant.
    3 Physical machines (blades) hosted within a separate physical quadrant
    Both quadrants are extremely well connected, local, 10GBit/s fibre.
    There is local storage in each quadrant, no storage replication takes place.
    The 3 machines in the first quadrant are MS clustered with shared storage LUNs on a 3PAR filer.
    The 3 machines in the second quadrant are also clustered with shared storage, but on a separate 3PAR device.
    8 shared LUNs are presented to the cluster in the first quadrant, and an identical storage layout is connected in the second quadrant. Each LUN has an associated HAFS application associated with it which can fail-over onto any machine in the local cluster.
    DFS replication groups have been set up for each LUN and data is replicated from an "Active" cluster node entry point, to a "Passive" cluster node that provides no entry point to the data via DFSn and a Read-Only copy on it's shared cluster
    storage.
    For the sake of argument, assume that all HAFS application instances in the first quadrant are "Active" in a read/write configuration, and all "Passive" instances of the HAFS applications in the other quadrants are Read-Only.
    This guide: http://blogs.technet.com/b/filecab/archive/2009/06/29/deploying-dfs-replication-on-a-windows-failover-cluster-part-i.aspx defines
    how to add a clustered service to a replication group. It clearly shows using "Shared storage" for the cluster, which is common sense otherwise there effectively is no application fail-over possible and removes the entire point of using a resilient
    cluster.
    This article: http://technet.microsoft.com/en-us/library/cc773238(v=ws.10).aspx#BKMK_061 defines the following:
    DFS Replication in Windows Server 2012 and Windows Server 2008 R2 includes the ability to add a failover cluster
    as a member of a replication group. The DFS Replication service on versions of Windows prior to Windows Server 2008 R2
    is not designed to coordinate with a failover cluster, and the service will not fail over to another node.
    It then goes on to state, quite incredibly: DFS Replication does not support replicating files on Cluster Shared Volumes.
    Stating quite simply that DFSr does not support Cluster Shared Volumes makes absolutely no sense at all after stating clusters
    are supported in replication groups and a technet guide is provided to setup and configure this configuration. What possible use is a clustered HAFS solution that has no shared storage between the clustered nodes - none at all.
    My question:  I need some clarification, is the text meant to read "between" Clustered
    Shared Volumes?
    The storage configuration must to be shared in order to form a clustered service in the first place. What
    we am seeing from experience is a serious degradation of
    performance when attempting to replicate / write data between two clusters running a HAFS configuration, in a DFS replication group.
    If for instance, as a test, local / logical storage is mounted to a physical machine the performance of a DFS replication group between the unshared, logical storage on the physical nodes is approaching 15k small files per minute on initial write and even high
    for file amendments. When replicating between two nodes in a cluster, with shared clustered storage the solution manages a weak 2,500 files per minute on initial write and only 260 files per minute when attempting to update data / amend files.
    By testing various configurations we have effectively ruled out the SAN, the storage, drivers, firmware, DFSr configuration, replication group configuration - the only factor left that makes any difference is replicating from shared clustered storage, to another
    shared clustered storage LUN.
    So in summary:
    Logical Volume ---> Logical Volume = Fast
    Logical Volume ---> Clustered Shared Volume = ??
    Clusted Shared Volume ---> Clustered Shared Volume = Pitifully slow
    Can anyone explain why this might be?
    The guidance in the article is in clear conflict with all other evidence provided around DFSr and clustering, however it seems to lean towards why we may be seeing a real issue with replication performance.
    Many thanks for your time and any help/replies that may be received.
    Paul

    Hello Shaon Shan,
    I am also having the same scenario at one of my customer place.
    We have two FileServers running on Hyper-V 2012 R2 as guest VM using Cluster Shared Volume.  Even the data partition drive also a part of CSV.
    It's really confusing whether the DFS replication on CSV are supported or not, then what would be consequence if using.
    In my knowledge we have some customers they are using Hyper-V 2008 R2 and DFS is configured and running fine on CSV since more than 4 years without any issue.
    Appreciate if you can please elaborate and explain in details about the limitations on using CSV.
    Thanks in advance,
    Abul

  • Hyper-V replica vs Shared Nothing Live Migration

      Shared Nothing Live Migration allows to transport your VM over the WAN without shutting it down (how much time it takes on io intensive vm is another story)
      Hyper-V replica does not allow to perform the DR switch without shutdown operation on primary site VM !
      why can't it take the VM live to the DR ?
      that's because if we use Shared Nothing across the WAN, we don't use the data that Hyper-V replica can and then it also breaks everything hyper-V replica does.
      Point is: how to take the VM to DR in running state, what is the best way to do that ?
    Shahid Roofi

    Hi Shahid,
    Hyper-V Replica is designed as a DR technology, not as a technique to move VMs. It assumes that should you require it, the source VM would probably be offline and therefore you would be powering up the passive copy from a previous point in time
    as its not a true synchronous replica copy. It does give you the added benefit to be able to run a planned failover which as you say, powers of the VM first, runs a final Sync then powers the new VM up. Obviously you cant have the duplicate copy of this VM
    running all the time at the remote site, otherwise you would have a split brain situation for network traffic.
    Like the live migration the shared nothing live migration is a technology aimed at moving a VM, but as you know offers the ability to do this without having shared storage and only requires a network connection. When initiated moves the whole
    VM, well copies the virtual drive and memory before sending machine writes to both, then only to the new VM when they both match. With regards to the speed, I assume you have the SNLM setup to compress data before sending across the wire?
    If you want a true live migration between remote sites, one way would be to have a SAN array between both sites synchronously replicating data, then stretch the Hyper-V cluster across both sites. Obviously this is a very expensive solution but perhaps
    the perfect scenario.
    Kind Regards

  • How to Reorganize CSM200 Shared Storage in Solaris 10 x86 Oracle 10gR2

    I could use some guidance from those who are more experienced in RAC administration in a Solaris environment with ASM. I have a three-node RAC with Oracle 10gR2 instances on top of Solaris 10 x86 where the shared storage is a Sun CSM200 disk array which looks like a single disk to the rest of the world. I'm not very familiar with the CSM200 Common Array Manager but I do have access to use it.
    During initial setup, I followed the Oracle cookbook and defined a storage slice for each of the following: OCR, OCR mirror, three voting disks, and +DATA, for a total of six slices. I brought up the RAC and we've used it for a couple of weeks.
    This is a Dev and QA environment, so it changes pretty fast. The new requirement is to add a +FRA and to add a mount point for a file system on the shared storage, so that all three Oracle instances can refer to the same external table(s).
    However, I've already used all the available slices in the VTOC on the shared logical drive. I'm not sure how to proceed.
    1) Is it necessary to use the CAM to create two logical disks out of the single existing logical disk?
    2) If so, how destructive is that? I don't need to keep the contents of the database, but I do not want to reinstall CRS or ASM or the DB instances.
    3) Is it possible to combine the OCR and its mirror on the same slice, thus freeing a slice for reuse?
    4) Is it possible to combine all three voting disks on the same slice, thus freeing two slices for reuse?
    Edited by: user12006221 on Mar 29, 2011 3:30 PM
    Another question: Under 10.2.0.4, is it possible for the OCR and voting disks to be managed by ASM? I know it would be possible under 11g, but that's not an option as I am trying to match a customer's environment and they aren't going to 11g any time real soon.

    What you see is what happens when the Java runtime running on Solaris 10 x86 tries to load a library which is compiled for SPARC.
    Because of the native parts in SAP GUI for Java, compilations and installers are required for each OS - HW combination.
    The supported platforms can be seen in SAP note 954572. For Solaris only SPARC is currently supported.
    Because of the effort needed for compiling, testing, support etc. it is required to focus on OS - HW combinations widely used on desktop machines and Solaris 10 on x86 currently does not seem to be one of those.

  • SQL2008R2 cluster w/ several Named Instances -- shared storage best practice?

    Planning four node SQL2008R2 cluster; three named instances.  Each named instance requires exclusive use of a drive letter on shared storage.  Does the names instance need all it's files (data, logs, tempdb) on that exclusive drive?  Or can
    it use a drive shared by all 3 instances.  E.g. U:\SQLBackup\<instance-name>\...
    Thanks,
    Bob
     

    You will need at least one drive for each instance + 1 one for cluster Quorum (unless you go for fileshare).
    My recommandation would be:
    Instance1
    E:\SQLDataFiles
    F:\SQLLogFiles
    G:\SQLTempFiles
    Instance2
    H:\SQLDataFiles
    I:\SQLLogFiles
    J:\SQLTempFiles
    And so on.  If you are considered that you might run out of drive letters you could make a single Drive letter pr. instance and then attach the 3 drives as mountpoints into this drive. That way you will save 2 letters pr. instance.
    As for just using one single drive pr. instance with all 3 kinds of files: Don't go there - the performance gain of splitting then into 3 drives as laid out above, is at least 50% in my experience. Remeber also to format the sql drives with NTFS blocksize
    of 64K

  • Shared Storage & mulitple Macs

    Hi all, I have a few questions to ask. Im goimng to buy two new Mac Pro and two iMacs for my company.
    We are doing some editing on FCP and need the ability to share video files. The plan is to have a mac pro capture all the video (tape, dvd, ftp etc) I then want the iMacs and remaining Mac Pro to access that video and edit it. The turn over will be quick and storage of the video necessary (DV quality at most). My first idea was all the editing machines have separate shared storage over gigabit ethernet. Something like the Western Digital My World 2 2TB drive (one for each machine). Everyone would be linked up over a gigabit switch.
    What Im starting to wonder is if its possible to have the editing machines have a single shared unit that all editors can work off in real time. A device where all the captured video is pushed to and the editing machines can work off. Something around 8TB.
    Any suggestion or ideas on this workflow?
