Fresh CPU overhead on the IP hash load balancing?

• 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).

• Lighthouse of unusable probing with the IP hash load balancing.

  I read this in one Web site, but I would like to know the reason for this?

  Is it because the IP hash uses IP source and destination to select the path and so for the markup, it can only detect the failure of the link for one of the trajectory of two?

  Is there some user guide of VMware or documentation that talks about what I can read on this subject?

  Thank you and have a nice week,

  Anthony.

  Please take a look at http://kb.vmware.com/kb/1012819 and the links provided in this KB. This explains why probe headlight does not work with EtherChannel.

• IP hash load balancing

  Hello

  I tried to set up IP hash load balancing across our server of vmware.

  I configured added 4 nic to a switch virtual and added the ip routing of hash for all groups of port on the vSwitch.

  (it is noted that one of the port was the management vmkernel port group)

  I then found the physical ports on the switch that the nic 4 plug and adds in a port channel.

  I used the following commands to create the Group of channels

  config

  interface port-channel (number)

  to add ports in the channel of the port:

  config interface ethernet (port number)

  channel-group 1

  I did it for all 4 ports to which the 4 server nic was connected.

  Once I had done this connectivity network completely abandoned. Workstations were more able to talk to the whole server vm (domain controller, Server database etc.)

  I took the ports except the port channel group - and the restored network connectivity.

  Can someone tell what I'm doing wrong here?

  VMware does not support LACP, you must set up the Group of channels in 'market '. Please check your configuration of the KB below phyiscal switch port:

• Adpaters/active with the vPort ID load balancing

  Looking at the following configuration, my understanding is that some virtual machines in this group of ports will use vmnic1 and some will use vmnic6 (based on their ID vport).  Pretty simple.

  Assume that the uplink different swithces cards.  This works because there is no tree blocking one of the unplinks.  Question is: what happens to traffic on vmnic6 if the link fails? (failure of the local liaison, NIC failure, etc. - I'm even not consider upstream failure here).  My understanding is that vmnic1 will not resume because the windows are related to the vmnic6.  Only if there is a Standby adapter is there a link to relief for vmnic6 or vmnic1.  In other words, with vPort (no Etherchannel) of load balancing, two active/active adapters are not 'Standby' to each other.  Is that correct, or am I wrong?

  I ask because I see this routinely on customer sites.  But what I always have it set up as a channel of port for a single switch, if two switches or was to be used, then I made active/active and then included a Standby adapter for failover should one Fail of active principles.  Or, if all I need is resumed, not load balancing, I just did a single active/passive and alternate ports between them as a form of manual balancing groups.

  I always just assumed Active would not switch to another asset without a port channel/IP-hash config (where the whole reason for standby in the first place).  I'm quite right or completely wrong?  Later today, I want to test this is a lab while monitoring with top.

  

  With the default configuration in your example, the virtual machine-> Teddy assignment is when a virtual machine is running. In the case of a Teddy/link failure the VMs will be assigned to other natachasery. A standby NIC cannot be used unless there is a power failure.

• Someone at - he set up the Insight Log load balancing?

  Hello

  We try to log configuration Insight in a load-balanced, and cluster configuration. After the search tirelessly for blogs, the question on this forum, or other persons who completed it and shared their installation that I found nothing. The only thing that comes close is http://sflanders.net/2014/05/01/log-insight-2-0-beta-load-balancing/ , but indicates only how it will come in a future post!

  I was going to Setup Proxy HA, but from my understanding it will not charge the way UDP traffic that newspapers Insight will want to have it transmitted information. Because we want to send more, otherwise all traffic to syslog to log Insight area, we would need to use UDP 514.

  Those who have actually set up load balancing, you followed a guide? If not, could you share how you accomplished, setting up your environment to balance between several workers?

  Any help is appreciated!

  -Patrick

  Hey Patrick,

  I just posted a more practical guide this morning: http://sflanders.net/2014/06/24/log-insight-external-load-balancer-configurations/

  You can use HAproxy, but if you need UDP, then you're right in that it will not be to your needs. If you are looking for a free/free alternative, take a look at: downloads | Load balancer Zen

  If you have any other questions, please let me know!

• The console to load balancing proxy

  Hi people,

  I have set up 2 servers of vCloud Director for redundancy:

  Server 1:

  http address: vcd1.example.com

  Console proxy address: vcdcon1.example.com

  Server 2:

  http address: vcd2.example.com

  Console proxy address vcdcon2.example.com

  I've set up a public URL through a load balancer: vcd.example.com. It works perfectly - I can connect to the public URL on the load balancers and functions of vCD correctly.

  It is:

  https://vcd.example.com load balanced back end vCD servers vcd1.example.com and vcd2.example.com.

  Now I try to get the proxy to the console through the load balancers and have not been able to get this working.

  First, I checked the remote console works when connecting to the address consoleproxy on the servers of vCD, for example vcdcon1.example.com and vcdcon2.example.com. The console connects very well and I can connect to the virtual machine.

  I set up one address public consoleproxy on the load balancers, for example https://vcdcon.example.com that load balances at vcdcon1.example.com and vcdcon2.example.com.

  When the remote to a computer virtual console is launched, I get the following error:

  Unable to connect to the MKS: Timeout during an attempt to read.

  I tried this on a Juniper DX load balancer and a device of Zeus Traffic Manager and get the same results. On Zeus, I can see the last HTTP request sent from my PC before the above error is visible:

  CONNECT 10.10.10.100:902 HTTP/1.1

  10.10.10.100 is the public proxy IP console, i.e. vcdcon.example.com.

  I use self-signed certificates free for the public and back end https.

  Someone at - it work for vCD consoleproxy addresses of load balancing?

• 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!

• vShield 5.5 - load balancer - trying to implement the signed certificate

  Some background information for the context:

  vShield Mgr 5.5:

  -imported Root CA Cert and a CA-signed X.509 cert.

  -capable to connect to vShield Mgr with certificates of trust.

  VCD cells:

  -all certificates signed and imported

  -able to connect directly with certificates of trust.

  balancer load vShield:

  VM: vcloud.ourcloudnet.com (10.10.10.1)

  Profile: http/https, least_conn, 80/443, the members are the two cells of vCD

  We want to have a cert signed and approved for load balancer address (vcloud.ourcloudnet.com). I tried to follow the procedures described in the Administration Guide vShield 73 page, but I'm getting confused with the procedure itself. When he says "you can generate a CSR and get it signed by a certification authority." If you generate a CSR at the global level, it is available for all vShield edges in your inventory. ", which means generating a CSR to the Mgr level as opposed to the Edge level vShield vShield? I'm doing this all wrong?

  Need advice please.

  I understood the question. When the certificate is ready to be downloaded, I need to select Base 64 encoded instead of the DER encoded. This will allow me to see the signed certificate in the format plain text and then paste the contents of the certificate signed when I import the certificate in the edge of load balancer device.

  When I did that I also fell on another question I want to create a new discussion on.

  Thanks anyway for the help.

• Where to configure clustering: on the web server or a load balancer?

  Hi all

  a few installation questions. I read on clusters and where to set up the pool. My main goal is to reach stickness session, session failover. but I'll ask them later when I clarify below.

  If my installation is

  -> Cluster WebLogic Web server, I need to install the cluster weblogic web server plugin.

  If my installation is

  Balancer load-> cluster WebLogic, I need to configure the LB, cos the LB must meet certain criteria.

  My planned Setup is

  Webserver-> LB-> cluster WebLogic. the weblogic balancing is done at LB. I'll have to set up the LB to balance to the cluster.

  I think I'm NOT configure the weblogic on the correct Web server plugin?

  Configuring the web server is obviously a proxy directly through the lb.

  So my next qn: the configuration to the LB is to balance the weblogic cluster OR a list of all the backend .jsf page server? Assuming that my application launch page is a jsf page. Enjoy your advisor.

  (a) you have little sticky on LB. On the Web server, Weblogic Plugin will take care of permanent sessions.

  (b) Yes, you need to add to your weblogic.xml in the application. There will be no conflict. However, your heap memory usage will increase as you could store session information on two servers.

  "Circumstances and considerations should I need a LoadBalancer in front of my weblogic cluster? --

  The main reason you would use a load balancer is to keep the VIP for your application. He would charge the balance between the weservers. Also usually SSL is stopped at the level of load balancer. It helps you reach cross clutser replication etc... You can read this document... Failover and replication in a Cluster

• 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

  

  

  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.

• RV042 load balancing

• How to configure das MD3200i load balancing

  I would like to connect a MD3200i (with two raid controllers) to one of our Windows 2003 R2 servers without the aid of a switch.

  After most of the documentation, some things remain pretty obscure to me. I'm new to MPIO/balancing and cannot figure how to set up.

  Is it possible to connect 1 nic host to RAID 0 and another host nic to RAID 1 and then combine the bandwidth? Thus having 2Gbs instead of 1Gbs? Or is it only a redundant path sollution, happening the other controller in case of failure of the first line. How can I configure this regarding the IP addresses, subnets. And where is the configuered to load balancing. This is explained in the documentation? I can't find it. I found a few examples that include the use of a switch, but none with das sollutions.

  What I have is 4 the MD3200i UTP cables to connect to the host. 2 the high raid controller and 2 on the lower raid controller. And use that I have 4x1Gbs, resulting a connection 4Gbs to a single partition on the MD3200i of load balancing.

  Thanks for any help.

  Multiple paths and in windows 2003 load balancing is managed by the driver MPIO is installed when you install the 'host' or 'full' version install MD Storage Manager. There is no need to separately aggregated network adapters to get the aggregate bandwidth. The pilot, by default, uses repetition alternated on all ports connected to a single controller.

  Also, for a single virtual disk, all i/o through a single controller and the second controller acts as a redundant path. So, if you have 2 x 1 Gbps connections to each controller, you will have, at most, 2 Gbps for each partition. Now, each controller can have virtual disks, so the second controller may have a second partition that will also have a separate between 2 x 1 Gbps connection.

  You can set IP addresses and subnets that are similar to the way that you would with a switch as long as you can test the connection port. It would be wise for each NETWORK card on the host on a different subnet and each port on the MD3200i on the corresponding subnet. This will make it easier when you set up your iSCSI.

  You can use the configuration utility to MD in place your iSCSI sessions too

  Hello

  Does anyone know how to deploy load balancing in OSPF area 0?

  Any suggestion for documentation would be apreciated.

  Thanks in advance for your help

  Hello

  OSPF is only the equal cost load balancing, so you must have two channels with equal to the destination charges.

  This command must also be set to more than one:

  maximum-paths

  under router ospf configuration.

  I think you also need ip cef enabled.
