• Question on isolate the vmotion traffic.

  Hello

  I have a question, we try to isolate the vmotion traffic and I have a problem.

  I have two vswitches.

  Vswitch 0

  only management option selected, 10.85.85.4, 255.255.254.0 subnet, gateway 10.85.85.1, trunk, VLAN 85 port

  Nic0 and nic 1

  vswitch 1

  VMotion selected only, 10.85.80.2, subnet 255.255.255.0, gateway 10.85.80.1, access port, VLAN 80

  When I change the default GW on vswitch 1 change the default GW on vswitch 0 also and I lose
  connectivity.  I understand that you cannot have two vmkernel of GW, if this is not how to fix this?

  Thank you

  Greg

  It is correct as long as vmotion ports are on the same subnet, there will be no need for routing - whther vlan can span the main switch is a matter of idfferent.

• 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).

• VMotion traffic isolation, vlan trunking

  We have 2 full length M910 blade servers sitting in the dell blade enclosure. Installed esxi 5.0 on the two blades and joined them to the cluster.

  Each server blade full length a 8 network cards.  2 ports double aboard the card NETWORK and 2-port Ethernet mezzanine card.  All are connected to the internal cisco switch 3130 installed on the module e/s A1, A2, B1 and B2. all the internal switches are stacked together by the network team. and there is a link to internal switch (uplink) and an external switch (ports) that are on the vlan 137

  All the ports that are connected to the esxi host are configured as trunk on the switches of internal physical cisco blade by the network team. in our total case 16 ports (8 cards x 2 servers) are fixed to the internal trunk on cisco switch and there is internal cisco switch uplink and our external switch (located on vlan 137)

  On esxi5.0, we set up a big flat switch affecting all physical network cards to Vswitch 0.
  Please refer page for groups of ports configured.
  
  To isolate the vmotion traffic, we have configured tag (150) vlan different for vmotion. but vmotion does not work. Unable to ping of vmotion ips with each other.  But if I change brand VLAN to 137. vmkping works on the other and work of vmotion.

  If I change brand VLAN other than 137 to any group of ports (for example, management or virtual machine), I'm losing connection to the corresponding port group.

  
  I think that missing configure something on the blade switches internal cisco (3130). Please advise on what needs to be configured. I know that kind of why trunking is required. If you could explain the exact purpose of why the necessary circuits for esx would be great.

  What is advised to configure a virtual switch, such as a large flat switch or multiple switches
  Assigning to each switch port group. recommended configuration to enable balancing the increased load of incoming and outgoing and fail over.  detailed explanation would be really useful for non admins networks

  I will try to describe one of the possible configurations.

  First some facts/support:

  • 2 ESXi hosts
  • 4 blade switches
  • 1 external switch
  • 8 NICs in each server Blade (2 NICs for each of the switches)
  • vmnic0 and vmnic4 are connected to two different switches
  • different subnets / VLAN for vMotion (100), management (101) and VM networks (102,...)
  • all VLANS represent them different IP subnets

  Virtual network configuration:

  • 2 vSwitches: 1 for management, 1 for VM networks and vMotion
  • vSwitch0 for management and vMotion (vmnic0 + vmnic4)
    --> Management ports (VLAN 101) Group: vmnic0 (active), vmnic4 (at rest)
    -> vMotion Port Group: (VLAN 100): vmnic4 (active), vmnic0 (at rest)
  • vSwitch1: VM networks (vmnic1.. 3 + vmnic5...) 7)
    -> VM 1 (VLAN 101) port group
    -> Port VM 2 (VLAN 102) group
    -> ...

  Blade switches:

  • all the VLANS configured in the virtual network are present
  • all ports of downlink to the ESXi hosts are configured to trunk mode, all the VLANS allowed
  • at least 2 uplinks and the external switch configured as a trunk, EtherChannel (LACP)
  • ports of rising and descending liaison (on each of the switches) are a group of track link state

  External switch:

  • all the VLANS configured in the virtual network are present
  • four channels of Port/EtherChannels (LACP), one to each switch blade

  You can configure the VLANS on switches separately or by VTP. In any case, all the VLANS should be present on the switches of. If you need to route traffic between some VLANs, you must either set up a router on your network, or - in the case where the switches support and are properly authorized - configure routing ip (Inter VLAN routing).

• Isolate the port on a vSphere standard switch traffic

  Hello

  I deploy an environment where I have a pool of 100 virtual machines that live on a switch standard vSphere isolated. The virtual machines to communicate with the rest of the world through a virtual double-NIC machine. This configuration does not work as expected, but I would go a little further and to isolate the connectivity network, such as each virtual machine can communicate with the system of double-NIC and not each other. The switch standard vSphere, the pool of 100 virtual machines are all located on the same VLAN and group ports. I spent some research time through documentation, but I did find a clean way to implement what I want. The best I can get to each of the virtual machines 100 puts their own VIRTUAL LAN, but it is ugly and will be difficult to maintain. Is there something easier that I missed?

  Thank you

  Steve

  PVLAN, but you will need the distributed virtual switch.

• Isolate the vCenter and management host ESXi5.1 of LAN traffic

  I would add two Dell switches to an existing installation, create a private management network (192.168.x.x subnet) containing the hosts and vCenter server, so that the management traffic is isolated and in no way dependent on connectivity LAN... for now that the vCenter server and the hosts are on the local network using public IP addresses.

  Is this possible with vCenter as vCenter that one IP can be configured and how should we switch be configured to allow access to vCenter from the local network via the web and customer management interface vSphere.

  Thank you very much

  Gary

  Facing your audience of LAN?  I think it depends a little bit of what looks like your LAN.  I don't think - you need not NAT your management network.  If you simply use public IPs rather than private to your internal LAN, the answer is no.  I have a client who does this same thing using 191.x.x.x for its internal network.  You try to access your network over the Internet?  It would be a different matter, and I recommend that to consult a competent network engineer.

  In short, just because you go to a public IP address range a private range of IP addresses does not mean you need to NAT.  You see NAT several times when these IP address ranges are used because they are intended.  For example, a company has a single public IP address assigned.  It uses private in its local network IP addresses.  For devices that must leave the LAN and access the Internet, you would NAT because everyone has to share this single public IP.

  Without knowing a little more, I think you'd be fine with the standard range or switching (inter - VLAN routing layer 3).

  All the best,

  Mike

• Separate VSANS / Mgmt / Vmotion traffic on different switches

  Hello

  I want to build a hybrid Cluster VSAN 4 knots (6.x).

  I have 2 x 10GE switches dedicated for Taffic VSAN

  also 2 * 1GBE switches for management / VM / Vmotion traffic

  Each host has 2 10 GbE NIC, 1 uplink for each of 10GBE switches

  Each host also has 4 * rising 1GBE, 2 for each of the switches 1GBE

  My idea is to use 10GBE just for VSAN traffic (separate DVSWitch, an asset, a standby) on each 10GBE switch

  Also to use 2 Ports on the management traffic (separate DVSWitch, an asset, a standby) on each 1GBE switch

  And use 2 Ports on traffic VM (separate DVSWitch, an asset, a standby) on each 1GBE switch

  VMotion traffic would be on the same rising as management, but active / standby vice versa

  Question: is - this possiuble / useful to connect vmotion for 10 GbE uplink ports (active standby vice versa VSAN traffic)

  I appreciate any useful comment on my scheduled install (I have no boy networking)

  Couple thoughts.  You can run several vKernels to VSAN and vMotion (allowing one on each switch).  To VSAN, use of VLANS / subnets (one on each switch offers you a pleasant has / B space) while vMotion must have all the vkernel on the same subnet 2 ideally layer.  This allows for maximum reliability, in theory faster failover and access flow.  This also has the advantage of if your cluster is not big (bigger that say 48 ports) you can avoid having multicasting, leaving the switch (usually requires more quarrels with the cats of network) as each switch TOR will have its own VSAN network.    Then use the NIOC for butterfly and protect the traffic between them.  Now the NIOC is not as effective as SR - IOV (but its good enough) to 100% and you will maximize your investment 10 Gbps without swamping the things.

  • Network management interface VMkernel = explicit order of Fail-over = active P1 / P2 ensures 10.1.1.1/24 VLAN 100
  • vMotion VMkernel - an explicit order of Fail-over = interface = active P1 / P2 ensures 10.1.2.1/24 VLAN 101
  • vMotion VMkernel-B interface = explicit Fail-over order active = P2 / P1 ensures 10.1.2.2/24 VLAN 101
  • Machine virtual Portgroup = explicit Fail-over order = active P1 / P2 ensures 10.1.2.1/22 VLAN 102
  • Virtual VMkernel-A SAN interface = explicit order of Fail-over = active P1 / P2 in standby (or not use) * 10.1.3.1/24 VLAN 103
  • Virtual interface of SAN VMkernel-B = explicit Fail-over order active = P2 / P1 Eve (or not use) * 10.1.4.1/24 VLAN 104

  In this case, VLAN, 100, 101 and 102 will be on all switches.

  * 103 and 104 could be configured to only exist on each switch (has / B isolation, failover do not switch on the value and set up on both) or exist on both (and use standby) as described.  This design will focus on maintaining the communications host-to-host on the same switch (decreases complications with multicasting and reduces its lag time as VSAN traffic does not have to jump to another switch unless you run out of switch ports, but now with dense 40Gbps past using 10 Gbps break out in theory you could hit the limit of 64 nodes on a single switch).

  I'm curious of anyone thoughts on just disable the failover and forcing them to each core sticking to its switch (and accepting loss of communication) on this vKernel in the event of a switch failure.  I want to do some tests with both laboratory and to test the failover of the switch/path between both of these configurations (compared to a configuration unique vkernel).

  However, some people prefer a 'simpler' configuration if (and I'm not opposed to that).

  Duncan drawn active passive failover configuration with of the vKernel unique for each host.

  In theory not being not not as dependent on the NIOC for insulation of storage should help the latency for the short bursts it takes to NIOC launch design active active vs.

  Control IO SAN and virtual network

  • Network management interface VMkernel = explicit order of Fail-over = active P1 / P2 ensures
  • vMotion VMkernel interface = explicit Fail-over order = active P1 / P2 ensures
  • Machine virtual Portgroup = explicit Fail-over order = active P1 / P2 ensures
  • SAN VMkernel virtual interface = explicit order of Fail-over = P2 active / standby P1

• Running the software iSCSI on a different subnet than the management traffic

  I hope I'm missing something obvious you smart people might be able to help with.

  I am trying to put in place a small instance of vSphere using ESXi 4.0 Update 2 and unlike most of our environment, we use the iSCSI instead of fibre SAN storage.

  The intention is to set up a network on subnet A, for management and Vmotion traffic which will have 2 natachasery attached.

  We have a second 'B' allocated for iSCSI storage subnet and have 2 separate natachasery which will be implemented through two vSwitches, 1 Teddy for each.

  We have implemented the switch management/vmotion on a subnet and, of course, the default for this subnet gateway entry when asked.

  The iSCSI subnet naturally has a different gateway and so when I entered IP address on subnet B in the port of core, it seems always trying to route through the gateway to subnet an attack to storage not being is not visible.

  We have verified that the problem is not with the storage or the ESXi put in place by proving that if we give the iSCSI port IP subnet A (and also the storage) then we can see storage without problems - simply, the question seems to be everywhere to try to operate on a completely isolated subnet.

  Isolation of storage traffic is a customer demand, and not something that we cannot ignore.

  Anyone know if it's possible (and if so what should I do to solve the problem) OR should we look for to move to ESX Classis and use his ability to use 2 different gateways?

  I feel that I must be missing something pretty obvious I don't know there must be a way to achieve segregation of traffic on subnets for the other core activities such as vmotion, fault tolerance and management traffic.

  There is only one door of entry for VMkernel, then you can separate VMotion / iSCSI / fault tolerance than if not routable subnets, i.e. all hosts on the same subnet.

• The QoS traffic shaping and shaping tip

  Hello

  Could someone tell me what is the difference between traffic and shaping of edge smoothing?

  Kind regards.

  The main reasons to use the traffic shaping are to control access to the available bandwidth to ensure that traffic is consistent with specific policies and to regulate the flow of traffic to avoid congestion. Some reasons for example for the use of the following traffic shaping:

  Control access to bandwidth when the policy dictates that the average rate of a given interface must not exceed a certain rate.

  Configure traffic on an interface if you have a network with different access rates. Suppose that one end of the link in a frame relay network runs at 256 Kbps and the other end of the link works to 128 Kbps. sending packets to 256 Kbps may cause applications to stop using the link.

  A similar and more complex case would be a network of link layer giving indications of congestion on the terminal equipment of data access with different rate attached devices (DTE). The network may be able to deliver more speed transit to a DTE device to a precise moment than at any other time.

  If you offer a service of low speed, the traffic shaping allows you to use the router to partition your T1 or T3 links into smaller strings.

  The traffic shaping prevents packet loss. Its use is especially important in Frame Relay networks, because the switch cannot determine which packages have priority or what packages should be removed in the event of congestion.

  Specifying the rate of advanced formatting allows you to make better use of available bandwidth by allowing more data than the EIF to be sent if the bandwidth is available.

• limit the vMotion operations?

  We have the need for the migration of many virtual machines between host computers but want to set a limit of 2 simultaneous operations and would not change the advanced settings for vCenter.

  I am able to get a list of virtual machines and sequentially migrate them between hosts fairly easy with a simple loop foreach (example below) but how to increase this to two?

  Ideally, I wish I could just specify the original host and evacuate (2 at a time) virtual machines to other hosts in the cluster.

  $vms = get-vmhost "host1" | Get - vm *.

  {foreach ($vm to $vms)

  Move-VM - VM (VM-Get-name $vm.name)-destination "host2".

  }

  Thanks for the tips

  You can do something like this.

  Perform the vMotion in the background (RunAsync) and account if there is more than 2 running

  $maxParallel = 2

  $vms = get-vmhost "host1" | Get - vm *.

  {foreach ($vm to $vms)

  Move-VM - VM (VM-Get-name $vm.name) - destination "host2" RunAsync -.

  do

  {

  sleep 5

  } While ((Get-tâche-statut en cours d'exécution | where {$_.)) ({Name - eq "RelocateVM_Task"}). County - gt $maxParallel)

• Anyway is to isolate the files changed after generation? HTML HR 11

  I use RoboHelp HTML11.

  I've been looking for a way to isolate the changed files to a generated project

  The team currently sends, old and new, for the server guys in a zip file. The server guys asked us to send them only the new files repeatedly.

  My current challenge is to publish in a local directory, which is preserved, and use excel Macros to take all files newer than a timestamp (I put just before generation). He then zipped and expelled as before.

  Cannot publish it directly on the server. Do not have the permissions and cannot get them . The policy reasons that I understood it.

  Is there a better way to do it?

  I'll probably switch to a shell script if robohelp can do on its own.

  
  

  
  

  RoboHelp gives you the ability to publish on the current server directly with only changed files download, but you are able to use it.

  The problem is that it is not just the subjects that need to be downloaded. Many support in the change of output files every time that you build and they must also be downloaded. If you download only the changed items help may seem to work at first but research and so on will not have been updated.

  Because the HR has provided the option to download only what has changed and it is your policy of the company that blocks that, I think you should continue with the solutions infused House.

• Isolate the DHCP in vswitch

  Hi all

  I hope for some help that I spent the last 4 hours searching the Internet for an answer and does!

  I have a relatively simple ESXi installation which I use a development platform. I am currently only using a NETWORK card on the host server which is connected to a physical switch that uses the rest of the production for the company network.

  What I'm trying to do is to establish a network of simple test with three servers, a domain controller, another Member and an Exchange Server. The domain controller is configured to run DHCP by using the 192.168.1.x range. The domain controller has two network cards virtual, one linked to a vswitch which is connected to the switch of physics and the second NETWORK card that goes to a separate vswitch which other servers are connected to. The reason for DHCP is so that the technical team can create new VM machines with different operating systems and do not need to worry about configuring static IP addresses each time. The domain controller receives an IP address on the beach of 192.168.0.x network production network.

  A picture shows a thousand words, so here are the network config:

  

  The problem I have is that some devices on the production network to receive an IP address assigned to them from the DHCP server on the virtual rather than the DHCP computer in the production network. I'm running unauthorized DHCP server to stop what is happening but can't find a way to isolate the DHCP server so that it gives that IP address to the virtual machines connected to vSwitch1.

  Thank you very much

  Scott

  Hello Rocco,

  Thanks for the help.

  I did a little research focused on the development of infrastructure rather then focusing on the aspect of VMware configurations and found Server2008 will broadcast packets on all DHCP assigned with a static IP public network adapters, even if it is only not on the links. However, when the NETWORK adapter is set to DHCP, then the server will not broadcast it.

  So what I ended up doing puts the NETWORK adapter for DHCP and then booking the IP address for the server so that it is always the same IP address for the production and the custom of DHCP server DHCP Server give it to someone else.

  I tried using dhcploc and it works perfectly.

  Thank you very much

• Network traffic on the background traffic in basket

  I wonder if anyone can help here... I have 4 hosts in a cluster connected to a San.

  I noticed when copying data between the virtual computer is (even on the same subnet and host) the data leaves the host, knocks on the door and comes back.

  How can I stop leaving the hosts/san to improve the speed of data transfer between virtual machines?

  Thank you very much.

  P.S. the ESXi 5 storage and XIV.

  You can configure up to 4 088 ports per host with 1 016 being active, if the limit is not a problem in your case. However, you may need to reconfigure the number of ports in the settings of vSwitch, which requires a reboot of the host in order to take effect. (for maximum configuration, see http://www.vmware.com/pdf/vsphere5/r50/vsphere-50-configuration-maximums.pdf)

  Port 3 groups (one for each VIRTUAL local area network) on the vSwitch, within each of the subnet traffic will remain intenally, while traffic between subnets required routing, i.e. let the host.
