Single network or Multi vMotion Nic card

Here are our current design for our soon vSphere 5.1 deployment

There has a been a good bit of internal discussions on whether to use a single 10 GB for vMotion network adapter or use two NICs 10 GB for vMotion

Most of the debate has been around "isolate" the vMotion traffic and makes it as localized as possible

We all have the vMotion traffic is a vlan separate, vlan127 you can see in our design

The big question becomes exactly where will the vMotion traffic? What switches/links it really go?

Is this correct?

  1. If we start with a vMotion nic, then once that Vmotion begins traffic will be generated from the host lose the virtual machine and the host wins the virtual machine. In this scenario, traffic will cross a BNT switch. This leads to two conclusions

    1. Traffic is never as far away as the nucleus of Juniper
    2. vlan127 (vMotion) didn't need to be part of the trunk, go to the heart of Juniper to the TNB
  2. If we go with two NICs of vMotion, then the two 10GB network adapters might be involved in vMotion. This means that vMotion traffic between two hosts ESXi could hit a switch BNT, browse the battery connections (two 10 GB between the BNTs connections) and go to another host via a network card. GB 10 it has also led to two conclusions:
    1. Traffic is never as far away as the nucleus of Juniper. He remains isolated on a single switch BNT or moves between BNT switches through the two stack 10 GB connections
    2. vlan127 (vMotion) didn't need to be part of the trunk, go to the heart of Juniper to the TNB

vMotion traffic is just unicast IP traffic (well good, except for some bug) between ESXi configured for vMotion, vmkernel ports if all goes well insulated in a non-routed layer 2 broadcast domain (VLAN). Simple as that. Considering that the traffic will cross physically regardless of the physical NIC is configured for the respective vmkernel ports. The path between the two is obviously depends on the layer 2 switching/STP infrastructure, which in your case would be just the blade chassis switches.

Multi-NIC vMotion essentially implements several independent streams between different IP addresses and MAC, belonging to the same host. Consider the following:

Host A and B with vmk1, using physical vmnic1, connected to physical pSwitch1 and vmk2, using vmnic2, connected to pSwitch2. The two pSwitches directly the trunk the VLAN vMotion between them.

If the two hosts have only vmk1 is enabled for vMotion, traffic will never pass by pSwitch1. If host B has only vmk2 enabled for vMotion or you switch uplink, it'll pass the two pSwitches.

Now, if you enable the two interfaces for vMotion vmkernel, it is difficult to say how the hosts decide what vmk connects to that. You may find yourself going through the two pSwitches for the two water courses, or you're lucky and you end up with source and destination interfaces that reside on the same pSwitch. I don't know how ESXi decides the pairings, this article seems to suggest it's done deterministically for that in a similar configuration, the same key vmk would connect between them:

http://www.yellow-bricks.com/2011/12/14/multi-NIC-VMotion-how-does-it-work/

Whatever the case, unless you need to other hosts on different switches, connected through your hearts only, to be able to vMotion between hosts, there no need at all to mark the vMotion VLANS on your links between chassis and Core switches.

You see, your question of vMotion Multi-NIC is completely unrelated to this.

If we start with a vMotion nic, then once that Vmotion begins traffic will be generated from the host lose the virtual machine and the host wins the virtual machine. In this scenario, traffic will cross a BNT switch. This leads to two conclusions

  1. Traffic is never as far away as the nucleus of Juniper
  2. vlan127 (vMotion) didn't need to be part of the trunk, go to the heart of Juniper to the TNB

1. Yes.

2. Yes.

Circulation * could * crosses both switches BNT, according to what I explained above.

If we go with two NICs of vMotion, then the two 10GB network adapters might be involved in vMotion. This means that vMotion traffic between two hosts ESXi could hit a switch BNT, browse the battery connections (two 10 GB between the BNTs connections) and go to another host via a network card. GB 10 it has also led to two conclusions:

  1. Traffic is never as far away as the nucleus of Juniper. He remains isolated on a single switch BNT or moves between BNT switches through the two stack 10 GB connections
  2. vlan127 (vMotion) didn't need to be part of the trunk, go to the heart of Juniper to the TNB

1.Yes.

2.Yes.

Personally, I'd go with Multi-NIC vMotion use NIOC with soft actions in your config file.

  • How can I check who is using VMotion NIC?

    I have 2 installation hosts with 4 NICs (local storage) and I configured for VMKernel (VMotion) one switch with separate maps. These two are connected with a crossover cable and are configured with manual IP addresses. Migration of virtual machines stop works, but how can I be sure that the traffic is really from my separate vSwitch1/vmnic2 and does not block vSwitch0/vmnic0 + vmnic1 with all the virtual machines in the annex?

    I checked the network traffic on the host in vCenter, but during VMotion I saw massive traffic on vmnic1, but none on vmnic2, so I'm not sure if my configration is correct.

    Can someone help / advice? Thank you.

    docvirtual wrote:

    I know that I have not met ALL the requirements for VMotion, but that should not affect where the traffic is done by. And even cold migration should go through network cards configured.

    And that's where you're wrong. Migration cold uses your network management vmk0, which will use vmnic0 or vmnic1 and not the vMotion VMkernel.

    I just tested a migration cold between two servers. VMotion NIC was slowed while the NETWORK card for the management network yielded several MB/s in the migration process cold.

  • Omen of HP 15: Wifi stop working. Win10 shows only a single network and it connects to the WiFi

    Hi guys,.
    Since a few days my wifi stopped working.
    If I click the Wifi icon it shows only a SINGLE NETWORK (two maximum), but not mine!

    And I live in a building of 20 + networks, as you can see on the WiFi Analyzer (I'm the only red to the right)



    If I reactive / disable Wifi with fn + f12, it goes back in plane and Wifi mode mode and sees it eventually all networks:



    My Wifi is on top. If it is registered, Windows connects to it and then she abandons the connection; If it is not registered, and I try to connect, it says "you are not able to connect to this network.
    Is fun is that after a few seconds, each network disappears and alone is shown (probably the one next door... I don't know).

    I already tried to RESET the laptop MATERIAL by keeping the power button for 10-15 seconds with the laptop is turned off.
    I tried to follow these instructions (http://support.hp.com/us-en/document/c04649175) updated drivers (Intel 18.12.0.3, 18.12.1.2, 18.30.0.9 [10 default Windows], 18.32.0 [last drivers]) without success. Whenever I have install a new driver, I uninstalled the earlier software Wireless + restart.

    I tried to uncheked "allow this computer to turn off this device to save power" on my settings of Wifi hardware without success.

    HP network support said that I did not choose a Wifi (really? The problem is that I do not see my Wifi on the list!).

    This is unrelated to a new 10 Windows upgrade since I installed it months ago and this is the first time I have this problem :/ It has always worked

    I tried different settings too:
    I changed the channel, I put 802.11 g on my router, APSD off on the router.
    I put "Magic off packet, QoS ad hoc off, U-APSD off, fat wide channel, differential flow mode HT off" on the creation of the map without success. Nothing chaned.

    The hardware test detects any failure.

    Important note: If I close the router, it shows my network connection with full power and he connects to it. Then I come back in my room (probably 3/4 meters away), it MAINTAINS the connection for 30 / 40 min and he drops the connection and I cannot reconnect to it more. It has always worked perfectly in my room during these months (I bought it in March 2015), so the distance is not a problem, I'm 6 / 7 m away from the router.
    In this case, it shows my network (connected) and the nearby... and the other 20 networks +?

    The only way I have is USB tethering with my Nexus 5.

    Linux: I tried the WiFi on Freya elementary (Ubuntu linux OS base) and it displays 20 + networks available on the list. He has not the connection problem with my Wifi, but sometimes it stops working, Web pages stop loading and I have to restart Wifi to reconnect to the it (usually after 30/40 min of use it).

    -------------------------------------------------------------------------------------

    What is the problem? My Wifi card is broken? Should I call Italian support or if you have any suggestions?

    WAWood,
    I took a risk.
    I did a factory restore with recovery HP (I have a drive dedicated for her)... and it worked!
    I had to switch from Win8.1 to 10, but the Wifi problem is solved!

    I'm still guessing that was the problem...

    Now, I'm under Intel drivers 18.30.0.9 worm and all the networks work.

    In the next few days I'm checking the linux problem (reset deleted primary partition).

  • Need a driver for my wireless nic card

    I have a wireless nic card and cannot find a driver for windows 8. I don't know what brand or any info about this card because windows XP always loading a driver. How will I know what it is if I can find a driver for the card?

    Hey Rodney,

    Here's a suggestion to identify your wireless NETWORK card:

    1. [Win] + X
    2. Device Manager
    3. Right click on your NETWORK adapter
    4. Select Properties
    5. Go to the Details tab
    6. Select the hardware ID in the drop-down list of the property
    7. Right-click on the 2nd line of the value box
    8. Select copy
    9. Open your favorite Web browser
    10. In the search box, paste the value copied to the #8
    11. ...

    Once you have identified the manufacturer of your NETWORK card & model see the manufacturer's Web site to try to find the appropriate driver. Alternatively, you can also search on http://catalog.update.microsoft.com.

    If Windows 8 cannot find a driver for your NETWORK card automatically, I guess it's because it's an old. So I expect that you will not find a driver for Windows 8. If you find a Windows Vista or Windows 7 driver, they should work. Also, during the research for a driver to pay attention to the version (x 32 / x 64) as it should match your version of Windows 8.

    Hope this helps at & answers your question. If you have a problem with this answer please you with:

    • Version of Windows 8 (x 32 / x 64)
    • Manufacturer of PC & model
    • NIC (#8 above value) hardware ID

    and I'll see what I can do when I have a moment.

    See you soon

  • Several subnets on a single NETWORK adapter

    I have two subnets, I want to be able to use with my virtual machines on a server with 5.5 ESXi.  I have only a single NETWORK adapter that is available on the host.

    The VMkernel default Port, vmk0 is assigned the IP 10.208.82.34/29.  The default gateway is 10.208.82.33.  Can I add virtual network adapters to virtual machines and the ping without problem to a host outside the subnet 10.208.82.32/29.

    I created a second Port VMkernel, vmk1 and assigned the IP 10.108.65.38.  Then, I set up a second virtual NETWORK adapter inside a virtual machine with an IP address of 10.108.65.33.  I can't ping this new IP address, 10.108.65.33, to another host.   However, I can ping 10.108.65.38 without any problem.  If adding a second card virtual NETWORK to a different virtual machine and assign it 10.108.65.34, I thing ping 10.108.65.33 without any problem.  I cannot ping this address, 10.108.65.34, another host either.

    I know that the issue is not routing as doing a traceroute from a host shows the correct path is taken.  determination of route of 10.108.65.38 complete normally.  I don't have access to the network infrastructure, because it is a server in a data center.

    The VMkernel, vmk1, using the 10.108.65.38, is accessible from the default gateway and the other hosts in the data center.  However when I attribute 10.108.65.33 to a virtual machine, I can't reach that what anyone outside the 10.108.65.32/29 network, which is my problem right now.  If I assign an address in the subnet of 10.108.65.32/29 as the single IP address to a virtual computer, it still does not work is not a problem of routing within the virtual machine.

    I feel as if I had something simple here as it seems to work almost disappeared.


    Here is the configuration of the network:

    Network.png

    This is the routing table:

    ~ # esxcfg - road - l

    VMkernel itineraries:

    Interface of network gateway subnet mask

    10.108.65.32 255.255.255.248 subnet local vmk1

    10.208.82.32 255.255.255.248 subnet local vmk0

    by default 0.0.0.0 10.208.82.33 vmk0

    I ended up having the point of provider the subnet 10.108.65.32/29 to their router or switch to 10.208.82.38, I have basic and then install a Linux router with iptables to route traffic to myself.

    Hello

    I have some bad problems while trying to use the following workflow: 'Clone, windows with a single NETWORK card. I always get the following error message: "task"CloneVM_Task"error: a specified parameter was not correct. "

    "Spec.Identity.Password.Value (name of the dynamic Script Module: vim3WaitTaskEnd #20).

  • Single NETWORK adapter with 5 IPs

    Hi guys,.

    I'm new to ESXI 5.5 and have a question. My server has a single NETWORK card and I got 5 fps by my ISP. I want to run 4 virtual machines on my server. I want one of the IPs to be assigned to the hypervisor and the 4 other IP address to assign to each host.

    Is this possible with a single NETWORK card, if so, can someone guide me in the right direction on how to accomplish?

    Thank you!

    Unless your service provider restricts the number of MAC addresses on the same switch port (your uplink port), there is nothing special you need to do. Simply assign an IP address to the host as well as each of the virtual machines. That's all.

  • Host with 2 NIC cards

    I have a host with 2 NIC cards.  I created a Windows prompt with 2 NIC cards.  I would like to bind each NETWORK card on the client to a different physical NICS on the host.  Is there a way to do this?  They always end up both bind to the same network adapter.

    Hello.

    You can do it.  Assuming that you have a Windows host, make sure that VMWare bridge Protocol is linked both to the network adapters on the host.  Then, use the VMware virtual network Editor to set VMnet0 until the bridge at 1 on the network adapters on the host.  Vmnet2 or another unused to the bridge on the other network adapter for the host.

    Good luck!
