ESXi NIC Teaming - switch Question

• ESXi - NIC teaming/load balancing

  If I use two network cards on the back of my ESXi server that provide load balancing or is it just for the failover?
  
  Each card NETWORK must have its own IP address?
  
  I have to manually team network cards or is it an automatic process?
  Or ESXi provides only the load balancing, as appropriate...?
  
  If one of my virtual machines use it of full 1 Gigabit, another VM connection will use the other NETWORK adapter connected?
  
  

  To add to the reply by Dave - it's technically not not balancing load even if it is called VMware - the best description is load balancing - type three methods Load Balansing ESXi offers are:

  1. Port according to ID - this the method by default when you have 2 or more physical NIC connected to a virtual switch. The VM traffic is realized on a physical NETWORK card based on the VMs virtual port ID and is incremented in the style of round robin. So if you have 2 NICs physical network, the first drop of will traffic VMs that the first NIC, the second VM shuts down to the second NIC, third comes out first NETWORK card and operating system on - host ESXi does not resemble the traffic so if VMs 1,3,5 are heavy network users they will go on the same NETWORK adapter even if the second NETWORK card can be totally unused
  2. Address based MAC - based similar to port, but the physical NETWORK adapter is selected according to the MAC address of virtual machines
  3. IP hash database - the physical NETWORK adapter is selected based on the starting and destination IP address - so if a virtual machine connect to several IP addresses that traffic will be disttibuted on all physical network cards - note this will require LACp be configured on the physical spend this ost ESXi connects to

• Layer 2 switch decision and redundancy NIC teaming/switch

  Hello

  Imagine that I need to provide a reliable network between two mainframe environment.

  Basically, there is a NIC communication 'intra' between the two chassis. This 'share' NIC could be connected in a switched environment isolated too long which supports 1 GB. The idea is, instead of using a VLAN in our production environment existing to allow communication between the two chassis, people would use a small switch instead, totally isolated from the network to provide such a service of communication intra-NIC between the two chassis. My questions are:

  (a) agree you generally keeping a separate switch (maybe a new layer 2 2900 XL?) I could provide a more reliable environment than if I plug on new servers VLAN into my existing 3750 switch? Note that my switch 3750 in production is not a stackwise. It's just an autonomous one.

  (b) a small 2900XL switch (8 ports?) can do the 1000 MB? Also, I have recommended that we use copper instead of fiber for this.

  (c) in the past I heard people talk about problems with the grouping itself. I wonder if I just use a Gigabit NIC, copper, I either offer. Again, please let me know where the layer 2900 XL switches do not support gigabit.

  Your intuition is very valuable. Thank you.

  Yes, 2960 should suffice in this case your need. It has 24-port and 48-port port 10/100/1000 version as well.

• Are these viable designs for NIC teaming on UCS C-Series?

  Is this a viable design on ESXi 5.1 on UCS C240 with 2 Quad port nic cards?

  Option A) VMware consolidation of NIC with the load balancing of interfaces vmnic in an configuration active/active through alternate and redundant physical paths to the network.

  Option B) VMware consolidation of NIC with the load balancing of the interfaces in a configuration vmnic Active/Standy by alternate and redundant paths of material to the network.

  Option A:

  

  Option B:

  

  Thank you.

  She really comes down to what means active/active N ° and type of switches upstream.  For ESXi NIC teaming - Active/Active load balancing provided the opportunity for all network links be active for devices different comments.  Grouping can be configured in a few different methods.  The default value is by ID of virtual port where each guest computer is assigned to an active port and then also a spare port.  Traffic to this host would be only sent on a connection at a time.

  For example, suppose 2 Ethernet connections and 4 guests on the ESX host.  Link 1 for switch 1 would be active for 1 and 2 and 2 link to switch 2 backup for 1 and 2.  However 2 link to switch 2 would be active for 3 guests and 4 and 1 link 1 switch backup for 1 and 2 comments.

  The following provides details on the configuration of the card NETWORK is teaming up with VMWare:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=1004088

  There are also opportunities for LACP configuration in some situations, but there is a material special considerations on the side of the switch, but also on the host side.

  Keep in mind that the vSwitch does not blindly broadcast/multicast/unknown unicast on all ports.  He has a strict set of rules that prevents loopback.  It is not a traditional L2 redirector so loops are not taken into account in an active/active environment.

• C200 M2 Windows 2008 R2 NIC Teaming question

  I have a c200 M2 Server with a map of map NETWORK Broadcom addon (N2XX-ABPCI01).  I would like to create a NIC team with all 4 cards (2 on board and 2 Broadcom).

  I found the enictool on the CD, but when I run it, it is not announce adapters or teams.

  How can I create a team on this server?

  Thank you

• NIC Teaming ESXi 4.0 recommendations

  Hi everyone-

  A very easy for you, but just need another opinion.  I have several hosts in my current environment of the virtual machine.  I add over several hosts.  Good grouping network adapters as well as the good deligation of the NIC issue.  What we have to work with-> 4 Integrated NIC (vmnic0-3), 4 network interface cards PCI (vmnic4-7), 4 (vmnic8-11) PCI network interface cards.  Not new in the world of the VM, but new to implement environmental...

  The current provision in the existing NETWORK adapter is as follows:

  vmnic0/vmnic3-> teamed for console Mgmt (vSwitch0)

  vmnic2, vmnic4, vmnic5-> available to the virtual machine (vSwitch1)

  It was setup by an admin before vm and I do not have a warm and fuzzy about how the management console is associated with and worries me because in my documentation, it States a specific nic should be designated for the vmotion, correct?  And this isn't on here too, even if the vMotion is enabled.

  What I would do is this way for team management console NIC

  vmnic0/vmnic4-> where NIC card breaks down, PCI NIC is ready and capable and vice versa (fault tolerance)

  Should I activate all the network adapters on the host?  Which would give me 2 integrated and available for the VM PCI 8.  I guess the network cards more better but sometimes too much of a good thing is bad...  Also is there a specific way to designate 2 just NIC for vMotion or is only a mute point?

  Thank you for your comments.

  > vmnic0 / vmnic4-> in the case where NIC card breaks down, PCI NIC is ready and able, and vice versa (fault tolerance)

  Yes, it's better than vmnic0/vmnic3 (of one physical chip)

  > Should I use all the network adapters on the host?

  Depends on what you want. Too many network cards will give nothing, except hedache if all VM traffic can be transmitted through 1 Gbit link without performance degradation.

  > Also is there a specific way to designate 2 just NIC for vMotion or is only a mute point?

  Use NIC teaming personal - seam vmnic1/vmnic5 as active/active or active / standby for VMkernel on vMotion portgroup.

• UCS C200 and NIC Teaming/FailOver

  As UCS C200 with management of a 10/100 and 10/100/two interface 1000 interfaces and PCIe with 4NIC

  I want to install CUCM 8.5 is the NIC Teaming/failover supported by UCS C200 and how to set up the NIC Managment interface with failover?

  Thank you.

  Hello

  As you install apps from the CPU on the server of the UCS, speech application team listed their recommendations here.

  http://docwiki.Cisco.com/wiki/QoS_Design_Considerations_for_Virtual_UC_with_UCS#Guidelines_for_Physical_LAN_Links.2C_Trunking_and_Traffic_Sizing

  You can create a NIC teaming in the ESXi via vSphere client software for traffic from from / destined for virtual machines.

  For C200, we have only one management port and if you use the management for MMIC traffic port, switch option is not available.

  However, if you choose to use host for MMIC traffic NETWORK ports, you can set up CIMC NIC mode for 'LOM shared' which provides the NIC teaming options.

• NIC Teaming: ID v-port-based load balancing

  Hey all,.

  According to VMWare ESXi does not support physical host interfaces LACP trunks.  I was told that the NIC teaming feature will allow you to specify which physical interface traffic is pushed through the source IP/VM database.  I was able to locate the NIC teaming settings in load balancing vSwitch properties, but I cannot determine how to set up a specific virtual machine, vNIC or source/destination IP address to use a specific physical NIC

  Can someone tell me how to proceed?  The setting of balancing says "Route based on originating virtual port ID"...  This isn't not always tell me how to assign a virtual interface to a specific physical interface.  Ideally, I would like to specify a destination IP address and a physical interface to use when accessing this IP address.  Simply being able to map a group of virtual machines to use a physical interface (without going through the VM groups on different vSwitches) would do well.

  Any suggestion is appreciated.

  Thank you!

  Intellectual property of hash based mode, 1Gbit/s physics 2 network cards can be effectively combined in 1 2 Gbps link?  Meaning regardless of VM, source/destinaltion IP/network, traffic etc will be shared between the two network cards until they are both is completely saturated?

  No, certainly not. It's like Weinstein explained. The NETWORK card used is based on the source and destination IP.

  You can take a look at VMware Virtual Networking Concepts that explains the different modes in detail.

  Route based on the hash of the IP ... Regularity of the distribution of traffic depends on the number of TCP/IP sessions for unique destinations. There is no advantage for the bulk transfer between a single pair of hosts.

• NIC teaming and aggregation rate

  Hello

  I need help on configuring NIC teaming on our ESX. We have a HP Server with 6 network adapters I already configured the vSwitch for VMkernal, VMotion and Service Console.

  Now, since the ESX will run at various Web servers I want to do is aggregate throughput of EPS of 1 GB to give me a flow of 4 GB total. What I've done is created a vSwitch and alllocated 4 NICs to the switch and created a port called 'Prod LAN' and receives the NIC 4, also on our Cisco switch I trunked 4 ports.

  What else do I need to do to make sure that I have configured correctly the NICs, so that when we assign the network adapters on the virtual Web server computer it can use aggregate 4 GB throughput. Also that I also want to make sure, if some fail NIC 1,2 or 3, I always have speed on the port.

  Thank you very much...

  Duncan has identified the problem above with what you are proposing.  You may agree with your config if a physical switch entire fails but as stated above, if you lose an single link on one of the aggregates that ESX will add a unique link from the passive cluster causing the switch to become crazy.

• NIC teaming on HP Blade

  I use HP Blades as my servers to host ESX 3.5 update 3. I have only 2 NETWORK ports on each host and I would like to implement the NIC teaming, but I'm confused on whether I would run into any problems if the vmnic should fail.

  I set up vswtich0 with three groups of ports - the primary NETWORK card for my Console Service (VLAN12) and port groups Vmotion (VLAN3) is vmnic0 with vmnic1 failover

  I also created another group of ports for the VMservers vmnetwork (no VLANs) on vswitch0 with vmnic1 as a principal port with vmnic0 my failover group.

  What concerns me, is the port group settings switch to vmnic1? For example, if vmnic0 tilt vmnic1, will I run into issues because the Service Console is running on VLAN12 and Vmotion works on VLAN3, and vice versa with the port vmnetwork group.

  Hello

  You will need to implement VST where you master all the VLAN to the vSwitch through each Teddy.

• ISE Cisco 3395 NIC Teaming/redundancy

  Is it possible to implement the consolidation of NETWORK cards on a 3395, I see that it is available on the SNS 3400 series? However, I was unable to locate any information about NIC grouping for purposes of redundancy on of the 3395. This feature is taken in charge, and if so, how I would approach him allowing of correctly? Thank you very much for the help in advance.

  Hello. For now, ISE does not support the NIC teaming/pipe of any kind. It asked that several times so I hope that Cisco will implement in a future version.

  Thank you for evaluating useful messages!

• iSCSI / vmkernel multipathing vs NIC teaming

  Hello

  I know of Configuration of VMware SAN Guide provides information about how to configure iSCSI multipath with vmkernel interfaces double on various uplinks.

  What are the disadvantages of using basic NIC teaming instead? Just an interface of vmkernel on a vswitch (d) with two uplinks. It will work properly about redundancy and failover?

  Kind regards

  I guess the difference is while using "Port Binding" iSCSI initiator uses vSphere Pluggable Storage Architecture to handle the load balancing/redundancy, that can make better use of multiple paths to NETWORK card available. Otherwise, the initiator will use vmkernel stack ensures redundancy network and balancing in the same way as a normal network traffic.

  I suggest that you look at the great post on iSCSI multi-vendor, I think the 2 statements below will summarize the difference:

  "

  • However, the biggest gain of performance allows the storage system to scale the number of network adapters available on the system. The idea is that multiple paths to the storage system can make better use multiple paths, he has at his disposal than the consolidation of NETWORK cards on the network layer.
  • If each physical NETWORK adapter on the system looks like a port to a path to the storage, the storage path selection policies can make best use of them.

• What is the different NIC Teaming policy between vSwitch properties setting and Port-Group

  Hello

  I know that there r two ways to set NIC Teaming policy: vSwtich or Port Group.  What is the different?

  Who is the highest priority?    Could the port group properties overrides the setting of vSwtich? Or just inherit.

• NIC teaming with the IP hash load balancing

  Hi guys

  I have a virtual machine with a VMXNET3 10 Gbps. It is usually have a heavy traffic with a special server and saturate one of my two physical NIC of 1 Gbps in its PortGroup. I want to know what's going to happen if I turn on "NIC Teaming for this portgroup with basic IP hash load balancing". In my case the source IP address and destination are not change so the aggregates of traffic between my two physical network adapters?

  To avoid saturating completely the two 1GbE NIC, it can also be useful to look in charge based on the grouping and the NIOC. It will ensure that the other streams of traffic VM are not crushed by this machine a virtual when it saturates a network card. The disadvantage is that it requires Enterprise Plus licenses (using a dvSwitch).
