Standard switch DV Switch migration

Hello the heroes of VMware.

I intend to convert networking virtual switch to standard dv switch in my company in the context of ESX 4.1 to 5.5 upgrade infrastructure. We have about 160 guests and virtual 2000 computers in this project. From now on, we have rebuilt most of the hosts to 5.5 (dint want to upgrade, coz of the limitations of space on the startup of the Bank directory). Currently, we have created standard switches with the same configurations hosts 4.1.

The standard configuration is like this, vswitches 2. 1 for management and vmotion with 2 physical links.

2nd is for virtual machines with 4 X 1 gig nics. We are not view our uplinks, as we do not have virtual connect for our hp blades.

We did an analysis, and most of VLANS match through consolidation.  So we need 2 dv switches to 160 guests, one for the IPC and the other is for production.

Now us created these dv switches and added guests, but haven't removed rising standard switch, since the use of the network is quite high. Also, we cannot accommodate VMs downtime, but we can afford downtime of host (per host at a time).

As the migration of port groups will migrate all virtual machines on this group of ports from one switch to another, if we do that, we have the same number of uplinks on vds as with vss to carry the load.

Having said all that, can anyone give us some valuable tips on how to solve this problem and move to vds.

Thank you.

Thor.

To add more worries, vMotion will not VSS for VDS support (correct me if I'm wrong), which excludes the issue of putting a host into maintenance mode, remove all top links from VSS and link them to the VDS and replace the virtual machines on the host.

vMotion traffic itself does not care, but the workflow of migration requires the machine network virtual source is available on the destination host. It seems that you are due for 10 GbE cards to help face the apparent flood of network traffic.

To be fair, moving around the virtual machine networks is a rather low-risk. If you plan not to move the vmkernel interfaces, which said you are on a completely different vSwitch, it's really just a matter of ensuring that your VDS is configured with the appropriate uplink slots and groups of ports. You can start a workflow of migration to move physical uplink (vmnic) and the virtual machines at the same time. To test this, you can migrate virtual machines on a host, run a few test VMs and try it.

    Hi all

    We have HP blades and we try to add two new Cisco UCS servers in the same cluster where we have HP BL460 blades. VCenter is 5.5 U1 and U2 5.0 ESXi.

  • migrate VM switch distributed to a standard switch

    Hello

    I need to migrate a virtual machine that is hosted on a cluster with switch distributed to another cluster with standard switches.

    This migration is possible when the virtual machine is turned off.

    By default, migrate function I get the following error message.

    Is there another solution?

    (without removing the network adapters)

    Thank you, Sven

    You can check that the host of the virtual machine's network configuration is running. He is a relevant portgroup created on the vSwitch Standard VM.

    I tried to remove the network card and it time on the removing of the inventory, virtual machine and re-adding it... any ideas on how to get rid of this?

    Usually, it shows if the virtual machine has a snapshot, which was connected to the Group of 'old' port

    I want to migrate to a distributed virtual switch, but Ami don't know if it's possible. The problem is I onlyy a uplink public and I can't add the physical NIC as the standard switch and distributed virtual switch. IAM looking for a way to migrate the portgroup & physical uplink NIC in one step. Someone knows how to do this without adding a second NIC uplink? Please keep in mind that my vCenter is a virtual machine on this machine.

    Thanks in advance,

    Another person asked a similar question in which I looked at How to migrate from a vSwitch to the switch distributed - see if that answers your question.

  • VMotion of standard switch internal

    I use a vsphere 6.0 and I noticed that can vmotion VM has connected to a switch internal standard (vswitch without connected physical network card) without warning or error.

    It is really strange, in the I read Manual:

    By default, you cannot use vMotion to migrate a virtual machine that is attached to a standard switch with no rising physical configured, even if the destination host also has a standard switch non-uplink with the same label.

    OK, so it looks like its def a problem with the documentation then.

    I guess its either very old information are ensured through, or a very old mistake that should say some as "unless the destination host also has a standard switch non-uplink with the same label."

    Problem is that the customer did not use distributed, and the system is configured to use distributed now...

    Thanks for the reply

    Hello, the process would be even just reversed, rather than create vDS and the displacement of a vmnic both.  Do the same thing, create a new set of standard vswitches, create your port-groups and move a vmnic and test connectivity and migrate your virtual machines and move the remaining vmnic.

  • Present the VLAN extra - vSphere Standard switch

    Hello everyone.

    I currently have two Exchange servers, both with NIC that sit on the same IP range. ('abc')

    I need to add the secondary NETWORK card to each server, but the need of the intellectual property of sit on one VLAN different than the existing boxes. ("xyz") (Redundancy is the goal here).

    How can I present the 'new' VLAN ("xyz") to our environment vSphere ESXi 5.0 so that it is an option when you add a standard switch, instead of only 'None (0)' or ' all (4095)?

    Thanks for the time.

    -Brandon

    First, network cards connected to your ESXi host, are in one vLAN specific or are they shared resources to allow several VLANS?

    If they are defined to a vLAN, they you have 2 choices.

    (1) add another 1-2 by ESXi host network cards and link them to the new vLAN.  Create a new portgroup to the new VLAN and add network cards to your VM (s) for this portgroup.

    (2) move your network team the TRUNK port settings and allow the two VLANS.  You then need to change your existing exchanges with the ID vLAN appropriate, including your management & storage trade.

    * These two options will probably require downtime, or migrate all virtual machines off the coast of the host to make the changes. **

    If your ports are currently configured TRUNK, then the network team comes to allow access to the new vlan and you must create a new portgroup for this new vlan.

    I hope this helps!

  • Together-NetworkAdapter to DVS standard switch

    Thus,.

    We have a task where we must migrate VM a DVS Standard switch switch networks and vice versa.  The problem is that they label network are of the same name.  These virtual machines are currently on the DVS.  It seems pretty easy to go from standard to DVS with the option - DistributedSwitch, but can't seem to make it work the other way around.

    This:

    Get-VM $vm | Get-NIC | Network card set -NetworkName '10.10.10.x'

    He holds the DVS instead to the network for the standard switch label.  Is this possible to do?

    The two labels are the same.

    Hello, markdjones82-

    In general, I would say that this would involve the implementation of a new specification of configuration and virtual computer by using the method ReconfigVM() of an object VirtualMachine.  But it seems that in the version 5.1 of PowerCLI rel 2 (released yesterday), VMware add a parameter, 'Portgroup', to the cmdlet Set-NetworkAdapter .

    So now you should be able to do something like:

    ## get the VM upon which to act$vm0 = Get-VM myVM0
    
    ## get the standard virtual portgroup from the VMHost on which this VM resides$oStdPortgroupToUse = Get-VirtualPortgroup -VMHost $vm0.VMHost -Standard -Name "10.10.10.x"
    
    ## set the network adapter using the new -Portgroup parameter to Set-NetworkAdapterGet-NetworkAdapter -VM $vm0 -Name "Network adapter 1" | Set-NetworkAdapter -Portgroup $oStdPortgroupToUse -Confirm:$false
    

    How does do for you?

    Message edited by mattboren: code was updated to include "-Standard" param on Get-VirtualPortgroup call, as pointed out by markdjones82

  • standard switch cannot be deleted

    Hello

    I used standard switches, but I moved all hosts of a dvswitch standard switches

    There is a very strange case

    on a standard switch can not be removed

    It shows that some VMS use

    but it's wrong

    as you go into this virtual machine and change the settings, you see, it has a single network which is connected to the dvswtich

    check if SRV01-DC1 has a snapshot, if the virtual machine integrated snapshots and you that migrate VSS to VDS, virtual machine will show its connected to VSS, because the computer virtual parent files are connected on.

    remove the snapshot of the virtual machine will fix the problem.

  • Switch std to distributed switch migration.

    I have 2 Dell T710 with 6 NIC cards.

    I configured on the 4 standard vSwitches.  Each standard vSwitch is connected to a physical network adapter card.

    I have a vSwitch for manage management, one for vMotion for iSCSI and one for traffic from the virtual machine.

    The reason I set up is to put the vMotion, iSCSI on a different NETWORK card and so another port on the physical port in order to get the maximum flow.

    Now, when I tried to configure a switch to vDistributed.  I was reading this document from vmware (http://www.vmware.com/files/pdf/vsphere-vnetwork-ds-migration-configuration-wp.pdf) and there seems to be all the VLAN based.  In the vDistributed switch, I create the port group, and then associate the group the dvUplink ports and the dvUplink will map to the physical NETWORK adapter on the host.

    I don't seem to find an option to specify the Group of ports on the dvPortGroup if East of vMotion, management and/or iSCSI traffic.

    I'm missing something.

    Can someone tell me some good practices of switch vDistributed?

    Thanks for the information and have a good year.

    You will need to go to the host tab configuration, management network, distributed switch - then "virtual cards" - the Vmkernel ports for the distributed switches.

  • Isolate the port on a vSphere standard switch traffic

    Hello

    I deploy an environment where I have a pool of 100 virtual machines that live on a switch standard vSphere isolated. The virtual machines to communicate with the rest of the world through a virtual double-NIC machine. This configuration does not work as expected, but I would go a little further and to isolate the connectivity network, such as each virtual machine can communicate with the system of double-NIC and not each other. The switch standard vSphere, the pool of 100 virtual machines are all located on the same VLAN and group ports. I spent some research time through documentation, but I did find a clean way to implement what I want. The best I can get to each of the virtual machines 100 puts their own VIRTUAL LAN, but it is ugly and will be difficult to maintain. Is there something easier that I missed?

    Thank you

    Steve

    PVLAN, but you will need the distributed virtual switch.
