Migration to a new physical switch - boards?

Currently, we have 2 Cisco 3560 and migrate to Cisco 2 3850 in a stack.

We have 2 guests, each with 8 physical network interface cards

  • vSwitch0
    • Nic0, nic4
    • vMotion and MGMT
  • vSwitch2
    • The VM network
    • NIC1, nic2, nic5, nic6
  • vSwitch3
    • Storage/SAN
    • NIC3, nic7

We have an EMC SAN of VNXe3100 with dual storage processors

I think everything will switch accordingly, but our VCenter server is on the same subnet as our VM network so if I disconnect the VCenter gateway will not be able to communicate with the hosts. I doubt this is a big deal, but I was wondering if anyone had any advice?

Thank you

You forgot of told me what grouping load balancing that you use on ESXi? Anyway, if you do not use the hash of the IP, you can proceed as follows:

1. connect the new switch to the old, by using a port trunk (allowing all VLANs);

2. configure the ports on the new switch to support connections between the old switch;

3. configure the interface VLAN (including the INVESTIGATION period), but do not allow this interface;

4. move all ESXi rising to the new switch, try to move one by one and check the connectivity between each trip;

5. move all other connections from the old to the new switch;

6 stop the VLAN interface on the old switch and activate the interface VLAN on the new switch.

  • Migrating from a distributed virtual switch pass

    I have a cluster that is approved for business-more.  I would like the host to a distributed switch.  The configuration of the virtual switch is as follows:

    4 NICs connected to a host, the NIC are part of an EtherChannel.  The network adapters are teamed up with ip route based on the hash of the IP.  All network adapters are connected to the same vSwitch with port groups created for access to the different VLANS

    I did the following to try to migrate to the new distributed switch: I broke the EtherChannel and removed three network adapters on the virtual switch and assigns them to the distributed switch.  At the same time grouping NETWORK adapters on the virtual channel switch based on the originating virtual, we changed the port ID.  I then migrated the service console more for the new switch successfully distributed.  I have created groups of ports on the virtual switch.

    The question is when I re - create the EtherChannel falls hosts on the network.  I have noted the following: "see attachment".

    Anyone using EtherChannel with distributed switches?

    Any help would be appreciated...

    How to configure etherchannel on your Cisco switch? You may not use LACP or PAgP. You must use "channel-group mode on.

  • The steps required to perform a migration to a new server vCenter using distributed switches?

    We are currently on version 5.1 of vCenter and ESXi 5.1 on all our guests.  We use a vDS on our current server vCenter and will need to migrate to a new server vCenter soon.  Is there a documentation about the steps to migrate to a new server vCenter using switches distributed?  We hope to achieve this goal without any downtime.  The problem is that we need that VDS on our 10GB network for the aggregation of links.  If having to migrate guests at standard switches before moving them to the new vCenter server, there will be problems of network performance.

    Because information about your environment are stored in the database of vcenter al you should just be able to stand up the new vCenter server and that it points to the existing database

  • Migration of a virtual machine or a new physical box vCenter?

    Recently, I renewed my license for ESX 3.x for vSphere license keys.  I am now looking to upgrade my hosts of ESX 3.5 u5 to vSphere.  The vCenter esx 3.5 database is hosted on a physical SQL 2000 Server.  I bought the license for MS SQL 2005, but I don't want to do a upgrade inplace on the area physical virtual Center for many reasons that are not part of this community.  So now that I'm at a crossroads, set up a new virtual machine on the esx 3.5 existing hosts for installing vCenter and SQL 2005 to restore the existing database of vc to?  Or should I look to buy a new physical server to dedicate to vCenter and the database to MS SQL 2005 to vCenter?

    In my environment, I have 3 ESX host running on the blades with a total of 10 VM operation.  In the future, I'm looking to virtualize a couple of SQL boxes once I get running vSphere.  If you were me what would you do with vCenter?

    like saying it will "eat your own dog food".

    For us, we have 9 instances of vCenter and all run as a virtual machine, with the exception of 3. When that get-enviornment upgrade vSphere4, vCenter Server VM.

    This facility is fully supported and works a lot.  In addition, you will receive HA/DRS.  I would say affecting your restart your VM vCenter high priority.

  • Get rid of the physical switch between 2 ESXi - Layer2 virtual servers between boxes

    Hello

    It's maybe a stupid question, but I can't quite understand the answer so I might as well ask.  I have two physical hosts of ESXi in my lab and for various reasons wish to eliminate the physical switch between them, but while retaining full vSphere functionality (HA, vMotion, DRS etc.).  Is there a switch virtual/Repeater product can I buy/use (deployed on the two ESXi hosts in a HA configuration) who can give me this feature?  I would then use Teddy ports on each ESXi host to talk to each other and additional natachasery as switchports to the outside world.  i.e. can I do this with a kind of multi-Vyatta router configuration?  NSX?  Must also support multicast.

    Thanks for your help!

    If you want to get rid of the physical switch, simply do not use it. ETH-cable to directly connect the natachasery of these two hosts of ESXi. If your NICs have the ability to auto-mdi (x), there is no something special. Some older NICs may still require cable crossover, but this is not necessary with new hardware...

  • physical switch not able to ping VM

    Hi all

    I am very new to vmware so maybe silly question.

    I installed esxi 4.0 on one host that has 2 network cards. In that I have created two vSwitch, one for the service console and the other for the production network. Each vswitch has a connected physical network adapter.

    I packed three virtual computers, and it is connected to vswitch1 under the same group of ports with VLAN ID 100. I have set up the physical switch port which is connected to esxi host vswitch1 as a trunk port.

    My problem is I'm not able to ping of physical switch to virtual machines, but I can't do a ping of VMS to physical switch. also, I'm not able to ping each other vm.

    Thanks in advance.

    Welcome to the VMware communities!

    What the GS (guest operating system) runs on virtual machines? Make sure that it has no application in GOS firewall blocks network connectivity. For example, under XP, external hosts cant access the target, if the windows firewall is enabled.

  • Installation of VirtualCenter migration with the new database

    I have an existing installation of Virtual Center and sql server that was installed by an employee of the past. The installation needs cleaning and migration.

    So I decided to prepare a new physical server to host a new installation of VirtualCenter and another SQL Server. I installed VirtualCenter, and the database was created. But now I'm starting to think that she can't be as easy as adding ESX hosts to the installartion of Vcenter new/database and update the IP of the server for the hearbeat.

    So I have a few questions:

    (1) if I disconnect the old installation of VirtualCenter and ESX hosts, add them to the new facility, my storage adapters will remain intact?

    (2) I'll currupt one of my virtual machines on ESX host?

    If I can lose data, I'll obviously have to migrate the existing database, rather than nine.

    You can unplug and remove the hosts of their current instance of vCenter and then add the host in the new.  Don't hurt your VM.  You do not also lose connection also well to the storage fabric.

    Just keep in mind that moving to a new instance of vCenter will lose you all the performance and historical data as well as any rules DRS/HA, pools of resources, permissions, roles, etc.

  • My mail is migrated to a new system, server and they have adopted Microsoft Outlook which is terrible. I use Thunderbird for 20 years and loved.

    When my main mail server migrated to a new system, they used Microsoft Outlook to organize my email. I used it for almost 2 months and it's awful. I would like to restore my old Thunderbird program. It seems to be working: I get the number of messages in my Inbox on the Thunderbird icon and an audio invites all new messages are received. The only problem is that I can't get in my mail because Thunderbird will accept none of the passwords that I offer (I only have three). Can someone please fix it so I can reset my password or have Thunderbird recognize one of my passwords? The main server wants to open a new account in Thunderbird, but it means that I lose all the data from the old account.

    Thanks for any help you can provide.

  • FCP7 will not migrate to the new Macbook Pro

    I am running FCP7 on a Macbook Pro OS 10.10.5 Yosemite. Recently my GPU Macbook died, if I swapped my hard drive in a new machine. All my programs and preferences and settings appear to have migrated EXCEPT fine, FCP. When I try to open it, I get a prompt for the serial No. I put in the serial and message 777 n. "'I don't have the original disks so cannot do a re-install, just write down the series.

    I just try to open the program in order to convert the project files in XML format and open them in first.

    Wait... did you install the drive in another computer and try to boot from this drive? Or did you mount it and try to migrate applications off of it?

    FCP 7 do not migrate. He moved around the library and file system, those who are not returned when migrate you, so many critical parts of the PCF are not reduced.  The only solution is that you can not do... install the installer DVD.

    Hi Bruno.

    If you use odi 11g then you need less than 1.7 java and if you use odi 12 c, then you need Java 1.7 and above.

    I guess in your case you use odi 11g. Check the version of java to java and install java 1.6 also.

    Thank you.
