  Configurations of VMotion and VLAN

  ESXi 4.0 / 4.0 vCenter

  Can someone explain how to configure the ports VMotion using VIRTUAL LANs.

  Here's the design;

  Two network adapters for teaming on a virtual standard switch 0

  A network for management and another network for VMotion traffic

  The ports management group is on VLAN 103 and its default gateway is set to the network VLAN 103

  When I add a for VMotion VMkernel port group and configure the network, and I use the gateway of 103 VLAN by default I can't vmkping the other interfaces for VMotion similar configuration.

  If I change the default gateway settings and use VMotion gateway, then bad things happen, i.e. lose connectivity to the service console.

  Thanks,-Jeff

  Both an eon of ar sthjey the same physical segment (i.e., the plughed in the same physical switch) there will be no need for a gateway for the vmotion network address.

• Question on vNetworking and VLAN...

  Our server ESXi hosts and vCenter are version 5.1.  We add a few new servers which will be on our 10GB network.  Our guests up to this point have been on 1 GB.  We do not use the distributed switch.

  How is it important that separate us the Traffic Management and vMotion VM on VLANS separated when using 10 GB network?  We will have management, vMotion and groups of VMS ports on separate vSwitches.  We have our servers on the 1 GB using the VLANS separated but I wonder why is this necessary if you use the 10GB network.

  Really it shouldn't make a difference if you have 1 GB or 10 GB - the main reasons network to separate traffic through the VLAN is security and performance.

  Security - you want to make sure that the management traffic is isolated as it is essential for the control of your environment and the vmotion is not encrypted.

  Performance - again be capable of managing the environment is the key and by isolating the traffic will ensure that he will have the necessary bandwidth

  Also don't forget since you already VLAN have implemented the simplest method for new virtual machines communicate will be on the same VLAN

• Question about VMKernel iSCSI traffic and VLANS

  Hello

  This is a very fundamental question that I'm sure I know the answer too, but I want to ask him anyway just to reassure myself.  As a precursor to my question, the configuration of my ESX infrastructure is best described here: http://www.delltechcenter.com/page/VMware+ESX+4.0+and+PowerVault+MD3000i.  Or more precisely, we have two controllers MD3000i.  Each controller has two ports and each port is configured on two different subnets, with every subnet connected to the different switch.  ESX host are connected to two switches.  The only difference for the guide, is we have two MD3000i configured the same, connection to the same switches.  Each MD ports is configured on the same subnet, but different IP addresses.

  At present, we are in the process of upgrading our two iSCSI switches of humble Dlink DGS - 1224T to Cisco 2960 T of.  The switches have been and continue to be dedicated to iSCSI traffic, however, I'm trying to set up VLAN s on the side of the switch.  Originally, we used the default VLANS on switches, however, after you have added an another MD3000i, noted the Support Dell best practices is to separate each on its own subnet and VLAN MD3000i iSCSI traffic. This would result in iSCSI 4 VLANS, two on each switch and two for each MD3000i.  Firstly, is this in fact of good practices?

  Second, if I migrate preceding 4 iSCSI VLANS, as each switch port will actually be an access port, will there need to complete the VLAN ID field in the VMKernel configuration page? Presumably, this field is used when the tagging VLAN is used, but as our switches do not need any other rocking trunk (as they are dedicated to iSCSI traffic), there should be no need to fill?  I guess it would be prudent to keep the two existing subnets, create two new subnets and make changes to an MD3000i and connection of the ESX host.  Provided the switch and switch ports has been appropriate configured with VLAN on the right, the rest should be transparent and he wouldn't be Intel VLAN in all ESX hosts?

  Would be nice to get answers and thank you in advance!

  (1) Yes, it is best practice for ESX iscsi, having an independent network and vlan for iscsi traffic.

  (2) No, there is no need to mention anything in the area of vlan, if you use an access port. Its a mandatory thing than a choice. If you supply the id vland with access port, it loses connectivity.

  Please explain a bit why you need to create two different virtual local networks for each MD3000i. You are going to use several on the same ESX box iscsi storage? Alternatively, you use only a single iscsi and use these 4 ports for the same single VMkernel interface?

• Isolate the vMotion and storage traffic?

  We use ESXi 5.1 using two physical switches for management traffic and two physical switches for VM and storage vMotion traffic. We use a DVSwitch with VLANS separated for VMs (125), storage (126) and vMotion traffic (127). My question is really about the physical switch setting. I have installation of VLANs, 125, 126 and 127 on my main switch with each of them having a layer 3 interface. I think that only the network of the VM (vlan 125) needs a layer 3 interface. In other words, my VLAN storage and vMotion is not routable by removing the 3 layer interface.

  Does this sound correct?

  Another twist, I have a Juniper switch where all layer 3 interfaces are defined. It is connected to 4 switches in the rear of my IBM Bladecenter. Two of these switches are Cisco 1 GB switches that carry all traffic to the management through a vSwitch network. The other two switches are BNT 10 GB switches that carry traffic for Storage vMotion and VMs. Of course, it's a network connection, because it carries several VLANS.

  My only question now is should I eliminate interface layer 3 on my storage network located on one vlan separate

  Well, you need your storage system accessible on these IP addresses by the systems for the management of the other subnets or such? You already have all traffic from subnet inter between iSCSI and other networks? If this isn't the case, then there is no need to have routable iSCSI network.

  For the ESXi hosts themselves there is usually zero reason to have vmkernel iSCSI interfaces be routable since you already do management etc on another routable network (and responses of hosts would be sent there as well except if you define static routes custom).

• Management and Vlan native in different subnet?

  Can I have a management ip and vlan native in a different on AIR-1242 switch subnet and 2960?

  Native on switch = 1.

  The interface vlan 100 = 10.10.1.25X 24

  BVI ip to the vlan 100 = 10.10.1.25X 24

  -HM-

  Hello

  As far as I know, the management and the native will be the same... I guess... You have Vlan native as 1 on the switch and Int Vlan 100 on routing switch? Am I wrong? Let me know what are your needs... which will help me to help out you!

  for your question...

  Normally, we specify him vlan native on the switch and the AP so that communication happens... communication won't happen if there is a match of...

  Looking forward to hear from you!

• Script to change the subnet and vlan.

  Hello

  Please can anyone help with a script to change the subnet and VLANs on all the esx host in a cluster for the vmotion and management network interface?

  Thank you

  Astra

  I guess it worked because you pasted an out front, so:

  Get-Cluster mycluster. Get-VMHost | Get-VMHostNetworkAdapter | where {$_.} PortGroupName - eq "VMotion"} | {} %
  Game-VMHostNetworkAdapter - VirtualNic $_ - IP $_. IP - subnet mask "255.255.254.0" - confirm: $false
  }

  I guess that makes still out:

  Get-Cluster mycluster. Get-VMHost | Get-VMHostNetworkAdapter | where {$_.} PortGroupName - eq "VMotion"}

  2 vmknis right?

  If Yes, then it should work I think.

• Networking VMotion and fault tolerance

  We will configure separate vSwitches for management, vMotion and FT. Each will have a pair of physical interfaces. I wanted to know if it is advisable to have separate IP space for management of ESX, vMotion and FT of if they are all on the same VLAN? If the load is a determining factor, assume heavy vMotion and load FT. 192GO by potential server for 40-50 virtual machines per host.

  I'm a newbie to networking Yes, if separate IP space is a recommendation, which is the basis behind this reasoning?

  I recommend you set up 3 different IP subnets. The subnet IP public/business for the network management and two separate for vMotion private IP subnets and FT. All three go in the VMkernel and from what I've read so far, put them on the same subnet may cause problems with routes traffic through the appropriate interfaces. In addition to this, it makes sense for safety, as amvmware already mentioned.

• Random virtual machines after vMotion and Storage vMotion network loss

  Hi all -

  I have a couple of tickets open with VMware and our supplier of SAN, EqualLogic, on this issue.  Since the configuration of our production and DMZ clusters we noticed that the virtual machines will sometimes drop network connectivity after a successful vMotion and Storage vMotion.  Sometimes, although much less frequently, virtual machines also spontaneously lose network overnight.  What happened only a few times.  The strange thing is that the other guests on the VM host are fine - they lose any network.  Actually, I can do no more than 3 computers virtual host to another, and 2 of 3 can switch correctly, so that we lose the network.  The work around?  Simply 'disconnect' from the virtual NETWORK card 'reconnect' and the virtual machine will start the return packets.  I can also switch the VM troubled return to the host State and it will find the network.  I can it reboot and re - win network.  I can re - install the virtual card completely, and she re - win network.

  VMware has seen a lot of mistakes of SAN in our log files in order to update us our SAN firmware to the latest version.  That seems to have fixed that but we still have the issue.  Here are some of the specifications - all environments are virtually identical except for memory:

  Of PowerEdge R810

  NICs Broadcom 5709

  EqualLogic SAN running 5.0.5 F/W

  We use frames.  ESXi is fully patched.  I haven't seen a boss or not, it is only some guest operating system that loses the network, but we are a Windows environment.

  When a virtual machine loses the network, we can not:

  • Ping to it
    
  • Ping it
    
  • Ping him at the virtual machines on the same host or vSwitch
    
  • Ping outside our network
    
  • resolve DNS, etc..
    

  I followed some KBs VMware without success, including:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1003839
  http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & externalId = 1002811 (port security is not enabled)

  -All the VMware tools have been updated to the latest version correct and corresponds to the ESXi host
  -Connected to the service ESXi console, I cannot ping the VM problem by name of host or IP address, but I can ping do not affected by the issue of the OTHER virtual machines.  I can also pings the service console.
  -Connected to the troubled virtual machine itself, I cannot ping other virtual machines, I can't resolve host names, I cannot ping by IP.  The machine virtual CAN ping itself by IP, but not hostname.  I cannot ping other virtual computers on the same virtual switch or network by either IP or host name.  I can't ping the vSwitch network management.
  -All vSwitches are configured in the same way and the same.
  -Notify the switches is set to yes
  -There are a lot of available virtual ports
  -We tried the E1000 and VMXNET virtual cards with no difference.
  -All cards are configured to negotiate, but we tried to force individuals speeds as well as with no difference

  I appreciate your help.  I have problems getting anywhere on this issue with the sellers.

  Still having the issue...

  Sometimes, it might be useful to really check that all uplinks VMNIC for all VLAN does work them. Try this is to create a new portgroup on the vSwitch used by your virtual machines on the host of the first, put a test VM on the portgroup, then go into the NIC teaming policy from the new portgroup and select "Override switch command failover."

  Then down vmnic all except one in unused, then only a single VMNIC is active. Then set the portgroup VLAN to a production of VLAN and try to see if we could ping some expected from the different addresses. If it works, then move VMNIC work until unused and move up to another asset. Try again, and this for all the vmnic. If it works, then you have verified that the configuration of VLANS and other settings are correct on the physical switch in the face of this host ports.

  If several VLANs, repeat the process for all other productions VLAN. Then repeat on the other hosts.

  While that may take some time, occurs if everything is properly configured on the physical switches. When occurs a vMotion virtual machine gets a new "Port code" and is assigned to a new outgoing VMNIC. If there is an error of configuration on one or more physical ports that might seem random, but may still happen on VLAN x on y VMNIC. Given that Port ID policy you use indeed spread randomly VMs on the vmnic these problems may be difficult to diagnose. (Make a disconnection of the VM vNIC gives the virtual machine a new port-ID, which it will move to a new outgoing VMNIC, which might seem to solve the problem.)

• Existing vSwitch using and VLAN

  Hello

  I was wondering if it was possible to configure Lab Manager to use an existing vSwitch and VLANS configured in vCenter rather than create its own switch and VLAN?

  Thank you.

  Unfortunately not.  You will need to let LM create and manage their own groups of ports or switches.

  Note that:

  -When you bind a physical network to a vSwitch/vDS, LM creates a port group to represent the network (it also has an 'LM' tag in vCenter)

  -If you deploy a configuration "reserved", he made a vSwitch or vDS port group to represent the fence... and limit network traffic.  Again, when you look in vCenter, there should be an 'LM' tag to the object.

  Kind regards

• Difference between groups of ports and VLANS

  Hi guys

  I read ESX Admin guide 2 times till now, but I still don't know what exactly is the difference between groups of ports and VLANS? I understand, but if someone asks me this question I will not be able to respond with confidence.

  Network also label: my understanding is that it's just label No technical significance in configuration?

  Thanks in advance

  One VLAN is one of the many settings that you can configure for a group of ports, you also have the tabs security, Traffic Shaping and consolidation of NETWORK cards.

  Port group name, you associate you a VM port group must be placed systematically on other hosts if you want to migrate or virtual failover from one host to another.

• Grouping of Vmotion and service console nic?

  Hi, I would like to know if it is: 1: 2 Possible: recommended

  3: how it is done?    Can I use an IP private available only to the ESX Servers (which is not known to the network) that is 192.168.24.24 while having the CD on a production network?  I'll have to do the two ports, ports of junction and create separate for a vmotion and SC port groups by specifying the ID of the vlan?

  Any input would be appreciated.

  1 Yes it is possible

  2 Yes, it is recommended

• VMotion and Active Directory

  Hi all

  First post here.  I read up on top of the communities here as well as the Google search to find the answer to my VMware / AD question but have not found a definitive answer for her:

  Most said that it is NOT recommended to enable the snapshots on a VM AD as AD may be damaged.  If this is the case, does AD VMs should not be VMotioned as well because when you VMotion, you take a snapshot?

  What are the recommendations/experiences with VMotion and AD that you all have?

  Thank you

  VEEI

  It does not have a Flash disk for vmotion.  It does take a bitmap of ram, send that to the target esx server, copy becomes more ram for the vmotion and executed treatment hand.

  I don't take pictures of my ad for any reading except for the purposes of this component snap in a test environment. You wouldn't put snaps of online advertising, it is simply not good in my opinion.

  I wouldn't ban the shots, so I'm not going to one of the modes of drive.

• VMotion and Service Console Mac address

  All,

  This may seem like a simple question, but how to find the Mac address of assocated to the port of Vmotion and the Service Console, as my network team ask Mac addresses for all static IP addresses.

  Cordially Spence...

  Click on the properties of the vSwitch to VIC, select the port of VMotion, then on the right, under the IP settings, you should see the MAC address

  Anything can be corrupted on your MacBook Pro, but from what you say, it seems that the cable drive/SSD/flash memory/SATA hard was seriously damaged. Him "question mark" means that your Mac is unable to find any bootable device, meaning that it does not yet detect your OS X drive.

  You should make a backup of your files (if you can still do it) and take the Mac at the Apple Store or dealer to get a diagnosis. There may be several damaged parts.
