Best Senario distributed virtual machine between SAN LUNS and replication fail over Senario

What the best best Senario for the installation of virtual machines on Big LUN or each VM on LUNS dedicated:

We planninig to implement 70 virtual machines on Esx 3.5 servers with replication LUN usisng CA of HP 7.

using 4 Big 800 GB data store on SAN RAID 5 Lun (each LUN will be contains 16 VMS)? or each VM will be deployed in separate small LUN 50 GB data store on SAN, RAID 5 and that this effect on the failure during the procedure on the DR Site if we choose BIG LUNs, also if this virtual machine includes 3 disks (store them on each disk on the different data store or the same data store)

Thank you

Remember that the virtual machine is a set of files and these files directly in your data store.  If you have a large store of data with multiple virtual machines, you must replicate the full data on the alternative site store in order to get to that data.  You can't really use greater SAN replication for just the simple vm in a data store.  SAN replication is not really aware of what is stored on it, she replied just blocks he knows.  You can copy the vm files individually as well, but it's more than a copy and not replication.  Otherwise, if you are concerned about vs some other vm, then using a small LUN would work better for you, or warehouses of data at multiple levels allows you to replicate the vm that are important to you and put the rest in a larger data store.

FCIP/FC/IP doesn't really matter.  Until a table can talk to each other, you're fine.  Our secondary site is hundreds of miles away, and replicate us very well during the period of INQUIRY, from one table to the other.

Yes, without SRM, you will need to manually register a virtual machine at the time, or write a script to work through all the.

  • Storage VMotion for a virtual machine with SAN LUNS attached to it. They are all going to?

    Hello

    Don't know which section of this post, so sorry if its wrong.

    We are eager to Storage VMotion of our SQL VM. These are our SAN 3040 of NetApp. In the virtual machine (windows 2003), they have also connected to the network SAN NetApp 3040 LUN.

    What I need to know is, if we tried to do the other (NetApp 3170) SAN Storage VMotion problems due to the fact that its storage not only fast vMotioning of VMs its self, but also the LUN or LUNS will remain on 3040, and the virtual machines moved to the 3170?

    Who is?

    If more info should help just shout!

    Cheers in advance...

    RDM's Raw card device.

    As I posted earlier, you need to move data to the Raw LUN for LUN Raw new either through data copy inside the VM if you map the new LUNS brutes who him or copy.

  • How a virtual machine sees log LUN and storage

    I am new to this so I aplogize for the stupid question

    If I have an Exchange CCR cluster

    1 server is 1 physical in a VM

    I understand that you need to map the logic unit number in physical compatibility mode on the side of the virtual machine

    But what I do not understand how the VM can read what is on that LUN.  I thought that a virtual machine must have been VMFS

    and for example, let's say the Qourum player, it is formatted to NTFS, then how can the VM read what is on this drive?

    Thank you

    Hello

    VMFS volume held the metadata or the RDM VMFS file pointer but the actual data will be on the Raw Lun and the BONE inside the virtual machine which will recognize it as a normal drive.

    Thank you

  • Is it possible to migrate a virtual machine between vcenter servers programmatically?

    Hi all

    My question is quite simple:

    -Is it possible to migrate a virtual machine between vcenter servers programmatically?

    Let's say we have two data centers:

    vcenter1

    -vm1

    -vm2

    vcenter2

    -vm3

    Is it possible to migrate vms between vcenter2 and vcenter1 programmatically? (or vice versa)?

    Also, I'm assuming that the appropriate VLAN and data warehouses across the different vcenters!

    Thank you

    Luis

    It is not possible, vMotion or migration live is in an instance of vCenter, it cannot be covered through two even if you have the data store accessible both vCenters and sets of the host. At best, you can unregister the virtual machine of vCenter 1 host and re-save as on vCenter 2 host, but once again, it is while the virtual machine is turned off.

  • Moving virtual machines between ESX environments

    Hello-

    I understand that when you try to move a virtual machine between two servers to ESX 3.5 disparate, one way to proceed is to use WinSCP to move the files to the machine and then 'register' the machine via the data store on the destination ESX navigation area.  I also read, however, that this practice may not be wise because it is better to execute a command to import, I think that vmkfsutil or something similar to this.  Hope to find confirmation on what would be the best practice in this scenario.

    Thank you very much in advance.

  • Replicate a virtual machine between an Intel host computer and an AMD

    Does anyone has experiences with using vSphere replication to replicate a virtual machine between Intel server cluster and a cluster of servers AMD?

    I asked myself this question the other day and unfortunately I have Intel hosts in my lab to test/demo so can not perform checks...

    I know that the only safe way to migrate a virtual machine from one host to Intel to a host of AMD is to use migration cold (ie the power off of the virtual computer), but that also applies if you use replication as a tool of "migration."

    I am aware vSphere replication can occur only if the source THAT VM is turned on, as it will make a copy of the initial/seed and then use CBT for replication of the changes... but because the goal of VM is turned off, I am correct in assuming that it is a form of "cold migration"?

    It works with the solution of Veem replication with VMware hosts.

    Reference:replication requirements. See the topic

    It seems to even work with Hyper V - replica.

    Hyper-V R2 2012 replica from INTEL to AMD? -Spiceworks

    In my view, this works for vSphere same replication as well. However, I will stay here with confirmation.

  • Working in a virtual machine of shared folders and not another...

    Hi, I'm new to the community but have worked with VMWare Workstation for about 9 months now. I have a set of 5 VM that I run on a regular basis, and I had successfully implemented the shared folders in each VM to a central folder on my C: drive host. I now have new versions of several of the virtual machine and I am trying to configure access to the same shared folder, but it will not be displayed.

    After you set up the information in shared folders in the virtual machine settings, I go into the virtual machine on my computer and expect to see under readers network, "Shared Folders on .host '. Who does not appear and when I try to map a network drive to //.host/Shared files /, it can't find the network.

    I compared the parameters between a virtual machine that has the Shared folder working and one who does not work, and I can't seem to find any differences.

    Here are some of my system details, if it helps:

    VMWare Workstation Version 6.5.2 build 156735

    Host of OS = Windows Server 2008 (64-bit)

    VM OS = Windows Server 2003 (32-bit)

    I've updated the VMWare tools in the virtual machine

    I have ideas of what I can try to get this working. Thank you!

    Try to upgrade the virtual hardware version 7 - maybe it does.

    Why don't you use the entries for the disks in cluster? -of course, you know that they are not stable in WS 6.5

    You can edit vmx file while the virtual machine is running? And is it safe?

    Hello

    Moved to the forum of the Virtual Machine and the guest operating system.

    If you edit the VMX while the virtual machine is powered on change is not levied until the power off then power on (not reboot) and there is a good chance that the change will be deleted when turn you off the system. So it is not safe to do so.

    well, in this case, we need to disable the standby of the end of the replication.

    So that everything in triggering replication does not trigger the snapshot of the suspension.

    Then test the if you get these errors.

  • Open with: 'Application name' - 'Name of the Virtual Machine' (2.0.4) AND (2.0.5)

    Hello

    Looking for help here...

    I notice that if I try to open a file on my Mac with an application of my virtual machine (Win XP Professional) I get 2 options for each windows application:

    1. Windows Media Player - Windows XP Professional (2.0.4)

    2. Windows Media Player - Windows XP Professional (2.0.5)

    The 2.0.4 option never works but the 2.0.5 option. I know this has something to do with the upgrade to the latest 2.0.5 version, but how do you / is it possible to remove the non-fonctionnel 2.0.4 options?

    Help, please! It's pretty boring.

    I have only haveone of virtual machine set up.

    Rich

    Make sure that the virtual machine is turned off and not suspended.  First locate the virtual machine in the finder.  You can do it by Ctrlclicking on it from the library of the virtual machine and choose Show in Finder.  In Finder Ctrlthe .vmwarevm of the virtual machine and choose "show package content".  If some shows as a folder go there.  Of in the virtual machine folder, you will see a folder named Applications.  Applications are the links to the Applications that you open in the virtual machine.  Remove vouchers there should do.  You may be able to determine the good by the update and the last number should be also the most recent.  These changes to take effect, you will need to reboot or restart the finder.  To restart the finder press and hold Esc, command,Option, and choose finder in there and restart.

    You can also just delete the Applications folder and then start the virtual machine.  Once that the virtual machine is started just enter the unit.  Entering the unit will recreate this Applications folder with the correct files in there.  You should always restart or restart the finder once this is done before it takes effect in the mac operating system.

  • Best way to move virtual machines between two clusters: HP and UCS

    Hello

    We move the virtual machines in the cluster UCSChassis: 6 guests ESXi in a Cluster of HPChassis.

    I wonder how do it with minimum downtime.

    Thanks for your help,

    If you have shared storage - expose the storahe where virtual machines are stored to both sets of guests - and the hosts are ocmpatible you can vmotion - or at least - to stop the mover VM's from the environment of the UCS and add it to the HP environment.

    If you can't share the storage you - you can use VMwate Standalone converter and V2V the VMs-

  • Migrate a template or a virtual machine between Sites

    Hi, I have a number of virtual machines created in a UAT environment. I can convert these VMs to models OR leave it as what.

    The requirement is to migrate the models to other sites. There is network connectivity between sites, but this is a separate system of SAN. There are the servers in each site that can be used to point to one common share, i.e. a dump file area.

    Via vCenter, I can't see a mechanism to export a model/VM in the OVF format and via the plugin Converter it seems possible to save files to the virtual machine on the disk, but the format of the workstation. In addition, the OVF tool seems to complicated for our needs.

    What process is preferable to move machines between sites - I need the process to be simple as possible.

    Thank you

    good things!  I'm glad that you have built it.

  • Connect virtual machine directly to LUN

    Hello.

    We have a physical (Windows 2003 R2) file server that connects to a SAN logical unit number.

    Is is possible to connect the virtual machine to the same LUN and be able to read the data?

    Thank you in advance!

    Yes, the rear drive even picked up by its E:\ status and everything was perfect.  I was a little worried at first as well, but it works so that I do not even stop thinking about doing more.

  • Can you pass offline virtual machines between data warehouses using the 'Migration' with the basic Kit Essentials feature?

    I speak not of Essentials Plus vMotion between hosts or migration of VMS between hosts and data warehouses online. Just curious to know if its possible to off a virtual machine and click the button to migrate to another store of data with the basic Essentials bundle.

    Welcome to the community - Yes you can - it's what we call a cold migration.

  • How do divide you a virtual machine between two data stores?

    We just installed a new SAN ICSI and created an ISCSI target on it. We have created a new data store on our server ESXi 4.0 and reminded our Iscsi target. Our virtual machines have two logical drives, for the system partition C: and E: for data. At present, all virtual machines are residing on the 1 data store, which is located on the local hard drives of the esxi server. How pass readers E: of the virtual machine to the SAN and let C: readers where they are?

    Hello

    Or if you don't have a Vmotion, you can use stand-alone Vcenter converter to migrate your VM on the same ESXi host. and during this process on the Advanced tab, you can divide your virtual disks in the desired data store. You can keep the C: drive as it is on the same data store and add new vmdk and select its data store that you want, and then can move E: or D: drive until the new vmdk.

    In this way, you can split your C: and other disks on different vmware disks on different data warehouses.

    Let me know if it helps.

    Kind regards
