ESXi - NIC teaming/load balancing

Similar Questions

• ESXi NIC Teaming - switch Question

  Got my first server ESXi upward and running last week.  This is my first production ESXi server.  The hardware itself has dual NIC from what I can tell, ESXi 4.1, if you put the NETWORK interface card in 'team' (I don't think that's the term they call it) ESXi will do a bit of himself load balancing, but also be able to use only one or the other in case of failure in the course.  So, my question is this, if I have 2 NIC on my server set in 'team', that I need to adjust the 2 ports on the switch to shared resources, as I do for any other server?  Or ESXi he manages in a way that I wouldn't need to put in place the trunking of the switch ports?

  That's right – from san traffice some through any port with all the load balancing methods you'll need to configure the same trunk ports

• NIC and load balancing

  Hello

  I have a new server ESXi 4.1. I currently have a cable connected to one of the two network adapters. When I put in place the management network, I selected the connected NETWORK card and left the other disconnect and deselect (via console settings directly on the physical machine). If I look at the network through vSphere Client cards, that's what I see: http://pix.sonhult.se/vmnics.png.

  What will happen if I connect another cable to my second NETWORK card? Will it set a new IP address for this NETWORK adapter? Could I have the load balancing or redundancy somehow?

  Thanks in advance!

  What will happen if I connect another cable to my second NETWORK card? Will it set a new IP address for this NETWORK adapter?

  Once you have plugged the network cable to your physical switch, you must assign to the vSwitch too. Once you do that the workload of the virtual machine and the management port will - by default - load-balanced in alternate way, which means that the virtual ports are distributed on the physical network interface cards.

  There is no need to assign an IP address any. An IP address is assigned only for the management port and the virtual machines within the guest OS.

  Could I have the load balancing or redundancy somehow?

  Yes. As mentioned above, this will happen automatically once you attach a second NETWORK adapter to the vSwitch.

  See http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf for more details.

• Network of twinning with Port trunks to support the host ESX VShere 4 with several NIC for load balancing across a HP ProCurve 2810 - 24 G

  We are trying to increase production of our ESX host.

  ESX4 with 6 NIC connected to HP Procurve 2810 - 24G 2 ports; 4; 6; 8; 10 and 12.

  The

  grouping of parameters on ESX is rather easy to activate, however, we do not know

  How to configure the HP switch to support above connections.

  Pourrait

  someone please help with a few examples on how to seup the HP switch.

  Help will be greatly appreciated as we continue to lose tru RDP sessions

  disconnects.

  Best regards, Hendrik

  Disabling protocols spanning-tree on the Procurve ports connected to the ESX host is going to promote a recovery more rapid port. Similarly, running global spanning tree is not recommended if you mix some VLAN iSCSI and data in the same fabric (i.. e. you do not want a STP process to hang storage IO). Spanning tree on your switches, look PVST (or Procurve BPMH) to isolate the STP VLANs unique events.

  In regard to the load balancing is, by default (route based port ID) value algorithm requires less overhead on the ESX hosts.  You may not use LACP on the Provurve the lack of facilities LACP ESX. You must use "route based on the IP hash" sideways ESX and 'static trunks' on the side of Procurve. Unless you have specific reasons why your network need loads this configuration, I'd caution against it for the following reasons:

  (1) IP hash requires thorough inspection of packages by the ESX host, increasing CPU load as load package increases;

  (2) the static configuration puts switch physics rigid and critical ESX host port mapping. Similarly, groups of ports all will fail as the Procurve batteries for management only and won't be on switches 802.3ad circuits Group (i.e. all ports of a group of circuits must be linked to a single switch) - this isn't a limitation of the port ID routing;

  (3) K.I.S.S. love port ID mix of port ID, beacon probe and failover on the port assignments you will get segregation of the raw traffic without sacrificing redundancy - even through switches.

  I hope this helps!

• Network load balancing ibm hs22 esxi 5

  Hello everyone, I have a HS22 blade connected to a bladecenter H with ethernet 2 e/s switching modules. So my HS22 has 2 nic and each blade is connected to the switch diferent on the center of the blade. I want to configure nic teaming on me HS22 Server ESXi 5. the load balancing mode I configured the default option on the ESXi. I would like to ask if I need to connect two ethernet io modules switching to a single external switch, or it's better to connect them to 2 diferent switches and maybe configure the VLAN same on ports of all swithces?

  It depends on the level of redundancy you want for your network. There should be no problem with 2 switches if they are properly configured.

  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.

• 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 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).

• NIC teaming + with leaves HP VirtualConnect and Cisco load balancing

  Hello

  I configure ESX infrastructure running on the blades HP (c7000 enclosure), VirtualConnect and Cisco 3750 switches for the uplink. My network configuration is based on the HP VirtualConnnect Cookbook, scenario 11.

  On the ESX Server, I configured a vSwitch with two NICs grouped. Each card can see a different network of VirtualConnect. Each VC network has active SmartLink.

  Each network of VirtualConnect is associated with two ports on a Bay of VC. These two ports are the uplinks in Cisco 3750 switches. Cisco switches are configured in a pile, and each port associated with the VC network is configured with LACP.

  Here are the facts:

  -Each network (Host A and host B) is properly configured for the LACP Protocol, in other words, the links are shown as active/active in the VC Manager.

  -Communication of ESX is good.

  -Failover and failback function OK.

  The problem: I can't get the load balancer to work. All virtual machines use a single bear. I tried different algorithms on the server ESX (source port ID, mac, IP hash hash) and the configuration of the equivalent from Cisco.

  I have attached a diagram of the physical network, but also the setting to ports.

  What Miss me? Thank you very much

  Pablo

  Because you want to create technically not a channel in an ESX perspective, you do want to use the hash of the IP.  If ESX attempts to send traffic through the two network cards, the cisco switch should drop this package as part of its loop avoidance algorithms.  You should be able to check that out in the switch port statistics.  You should not use the switch port ID.

  Not sure about the promiscuous mode.  Who do not have any account, as far as load balancing is concerned, unless the portgroup was not properly inherit the vSwitch properties?

• ESXi 5.5 nic teaming/LAG with trunking does not but it works on ESX 4.0.  Both are on the same switch. What gives?

  I have two hosts (vhost1 = ESX 4.0, vhost2 = 5.5 ESX) both are configured for the Group and both connected to a switch of 1544 Adtran L3 (named sw01).  vhost1 has been in production for several years with the config below and has been solid as a rock.  I'm trying to reproduce the installation of grouping/collage on vhost2 and it does not work when are associated but will work when you are using a single NIC (with or without aggregation).

  To be more specific about what does not work, two virtual servers have "Network server" (vlan 8) defined as a group of ports. Both physical and virtual servers on the same vlan cannot ping or resolve queries arp for virtual machines on vhost2.    Everything that is sent from a different subnet can connect to the virtual machines on each virtual server.

  So the question is this: why not ESX 5.5 works as ESX 4.0 when the configs are also near identical, as I can make them and they are connected to the same switch?

  Thanks for any input you can provide!

  Hello

  Do you share the vmnic for ESXi management and network of the VM?

  Try to follow the steps in this KB: VMware KB: NICs using EtherChannel grouping allows intermittent network connectivity in ESXi

  Trying to team adapters using EtherChannel, network connectivity is disrupted on an ESXi host. This problem occurs because grouping NIC properties will not propagate to the network management portgroup in ESXi.

  When you configure the ESXi host for grouping of NETWORK cards in attributing to the road based on ip hashload balancing, this configuration is not propagated to the portgroup management network.

  Workaround

  Note: to reduce the possibility network loss please change the route based on the hash of IP using this method of balancing load vSwitch

  1. Close all ports in the physical switch team leaving a single port as active.
  2. Change the Route based on ip hash vSwitch and load balancing management Portgroup.
  3. Set up the physical switch port channel.
  4. Activate the physical switch ports.

  Notes: Using this method will avoid a loss of connection when you switch to a port channel. Also make sure that under the properties for vmk portgroup # used for network management you tick the box "Enabled".

• Policy on NICs 1 Gb load balancing

  I use 6 x 1 GB NIC on the blades.  I have 2 NICs on board and 4 network cards provided by a single Mezzanine Card.  I have chosen a strategy of load balancing.  In view of the provision below, is there a reason to use load teaming instead of road based on the source port ID-based? I am allowed to use the load to team up if I want to but I don't know if there is no reason in this scenario-based:

  On Board 1 - Active MGMT, ensures vMotion

  2-edge - Production assets traffic

  Mez 1 - Active backup traffic

  MEZ 2 - Production assets traffic

  Martin 3 - Active backup traffic

  Mez 4 - Active vMotion, management standby

  If you have a license for LBT, use it. It is the only real policy load balancing that it monitors the load each NIC on a team and balances accordingly if there is an overload in one of the network adapters. Route based on origin Port ID just spreads the VM on the uplink (round robin) and does not care if one of the uplinks is most used and a used sub.

  I recommend using LBT on your Production and perhaps your backup traffic.

• End end NIC Teaming on ESXi with redhat linux guest operating system

  I'm running into a situation of lack of bandwidth for my backup server running inside the virtual machine environment. To increase bandwidth coming from a number of backup clients on my backup inside ESXi 5 server. I would like to collage x NIC 2 inside my redhat Server installation and train the grouping of NETWORK cards using Hash my ESXi host IP.

  What is the feasible way to provide a 2G from end to end connection to the outside world for my redhat backup media server? or there is an inverse?

  I don't think you need to add a second NETWORK card to the Redhat VM, which acts as a backup server as a single for the virtual computer NETWORK adapter can accommodate more load than 1 G.

  I have a couple of Redhat with a single NIC servers. VMXNET the following example shows this ethtool sees for the NETWORK adapter on one of these Redhat servers.

  [sfuller@rhel7 ~] $ sudo ethtool eth0
  Settings for eth0:
  Supported ports: [TP]

  Duplex: full
  Port: Twisted pair
  PHYAD: 0
  Transceiver: internal

  When I run a transfer TCP (using thrulay) from one server to another, you can see that it is 2.6Gbps average on the transfer of 10 seconds.

  So this shows that we can get more than the throughput of 1 Gbps on a single "GE NIC" on a Redhat VM.

  You will need to do is, as you mentioned, change load balancing on the host than the Redhat VM ESX runs using the road based on the hash of the IP. This will allow the Redhat VM to use more than a single teddy bear on the ESX host. You also need to several customers, including LSB of their XOR IP addresses differently, but you said you have several clients and so unless you're really unlucky with the IP addresses to clients have you should be good there.

  I hope this helps and good luck.

• 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.

• The order of failover and load balancing

  Hello

  I have the following scenario. An ESXi with 4 Gbps vmnic. The questions are:

  (1) if I have a group of ports configured for 'Route based on the original virtual Port code' in the policy of balancing load, and for the same port group I the option button 'Override switch failover command"checked, where I set up 3 of the active adapters vmnic, as well as the other vmic remaining as unused adapter, the ESXi uses the policy that I have configured (in this case 'Route based on the original port code') between the three vmnic load balancing marked as active? Or he uses them in the order that they appear in the section active cards?

  (2) Suppossed, I configured the four physical switch ports in an etherchannel group to use 'Route based on the IP hash' load balancing policy. In this situation, then I configured for a certain group of port to only used two active adapters and two others as unused? In this case, ESXi should balance the load using the method hash IP but only in two active adapters? Or it is a misconfigiuration and I should not configure my nic teaming in this way?

  (3) the official setup guide says "NOTICE on IP requires the physical switch be configured with etherchannel. For all other options, etherchannel must be disabled. ». How can I I configured my virtual network, if I have a few groups of political ports based on the hash of the IP to use load balancing and another uses 'Route based on the original port code. This is the case when I for example have two management ports using the same vSwitch with four vmnic (where they are configured as an Etherchannel in the physical switch). I would port one or several groups for virtual machines that use the IP of the hash method of balancing the load and vmkernel ports por management uses only a single adapter active with no back and as "based on the source port ID" load balancing as best practices said.

  Now, the four vmnic is the same for all traffic. The physical switch ports must be configured in an etherchannel group because certain groups of ports will use the method of IP hash, but others are not. The configuration guide I said SHOULD NOT use etherchannel if I won't use the hash IP method, but I'LL use it, but only in groups of one or more ports.

  Maybe I do not share the same vmnic from this situation.

  Finally, it's a philosophical question. What is the difference between 'The route based on the source port ID' and the 'road based on the source MAC Hash' load balancing policy? What is the purpose of the second? It is assumed that if I had two different MAC address in a virtual machine, it would be because I had two different virtual cards inside the virtual machine, which would be connected to two different port ID in the vSwitch, I can use the first strategy (based on the original port code). In other words, which would be the case where I had the traffic entering the same vSwitch but port ID with different source MAC address, so I should chose the method to distinguish the Source MAC address load balancing traffic?

  Thank you.

  Guido.

  (1) as long as you override vmnic only and don't change the policy for this group of ports, he uses the policy configured at level vSwitch and use the selected interface 3 with this policy

  (2) it should work, I don't think it's a problem for the switch receive packets on a subset of the aggregation. I do not think that Etherchannel is supported (IIRC, it is a Cisco proprietary protocol, VMware only supports LACP passive, which corresponds to the Port channel world Cisco.) Trouble me if I'm wrong!)

  (3) I think that's all right, as I have explained in 2), there is no special negotiations with the consolidation of VMware, the important thing only I know is to configure the port on the side of the switch channel if you decide to use the IP hash (that will lead to important questions)

  4) (self labeled) I think it may differ in some cases individuals, as when the operating system use the same MAC address for both NICs (aggregation in-vm) or if you advertise several MAC address for the same network card (ESX in a VM for example would make for its VM). Such cases differently affect this setting.

  That is the right question, and I'm curious to know if someone wants to develop on it!

• DSwitch load balancing

  I have DSwitch 5.5 in vsphere 6.0

  Two 5.5 esxi hosts to connect to these virtual switch of two network cards.

  NICs works in IP HASH (the real switch side cisco 3570 I did port channel). Everything works fine, but I have question.

  Can I do a load balancing for a single host examle: IP hash, on the other - on the virtual port original? If say, how? I can see only one setting for all VDswitch

  As you can see on your screenshots, settings are for port group and not overall overall dvSwitch. You can have different settings for each physical ESXi host though, all guests must use the same algorithm as specified by the port or load balancing groups. If you want different settings by physical ESXi hist, then you will need to use the local standard and undistributed vSwitches, but we can ask the question of whether such a potentially unpredictable and inconsistent configuration is desirable.

  On a side note, you can set up several groups of ports with different parameters on a vSwitch (d). However, mixture etherchannel/LAG/LACP IP - hash based load balancing with any other balancing as virtual port ID in the same uplink / vSwitch (d) is not supported.

  In addition, it is not sensible, your acts only physical switch as a single channel for all traffic and will not be able to differentiate as several ports on an ESXi host groups could do.
