• Access NAS storage of ESXi Server using VMKernel Port?

  Hello

  I would like to know the best procedure to connect to the NAS storage of ESXi host 5. I am able to connect to the NAS storage according to the screenshots listed in the link below.

  http://www.tintri.com/blog/2011/11/connecting-vSphere-to-NFS-the-easy-way/

  But, I saw different configurations in the past where port dedicated VMkernel is assigned to NAS and all storage goes into network 10 G. I try to do the same and created a VMkernel for NAS port. But I don't think that traffic is going over there as it is not used at all.

  I gave the IP address of the ESXi server on the NAS box to get access. I couldn't give address IP VMkernel sideways NAS. How can I make use of this IP VMKernel dedicated NFS storage?

  I want to implement the best way to pass NAS 10 G network traffic. In addition, How can I test if storage traffic crosses VMkernel port?

  Suggestions needed.

  Virtualinfra is right that you must use a different subnet for NFS traffic. You masked the IP range, so I don't see what you use, but make sure that the vmkernel and storage using a single subnet, not the management subnet. If you get an error, your use of a subnet that goes out the default gateway of the management port, or that you are using the same subnet.

  I wrote a few articles on the use of NFS with vSphere: http://wahlnetwork.com/2012/04/19/nfs-on-vsphere-a-few-misconceptions/

  Also, make sure that the vmnic can route traffic on that subnet, as in the case of the use of VLANs.

• Use of the Trunk Ports (Cisco) on the management interface

  Hi all

  Background:

  We are in the process of consolidation of 2 farms of esx servers and will end up with 10 guests in a single cluster. Guests come from 2 VLAN separate (say 10 of VLANs and vlan 20). A test I took one of the hosts of HA/DRS and tests with it. For HA and DRS to work efficiently and properly in common all resources, we all want vm to leave both VLAN access to move to any host in the cluster.

  The test:

  My single host mentioned above, I created 2 groups of ports on a vswitch, vlan10 tag and with vlan20, I deployed a VM and tried on the two IP address ranges. It worked (with the correct settings of defined IP by VLAN) but as soon as we resources shared the port used by the management of network vmkernel port we lost the connection to the HOST from a management perspective. What the question is that it is possible to connect the management network a trunk port? We have 2 network interfaces connected to the vSwitch and both used for the VM traffic as well as management traffic. That's how they are currently implemented except that the switch port is on a VLAN-specific rather than shared resources.

  Thank you very much

  Chris

  Hi Chris

  Yes, the network management also accepts the vlan tagging/trunking.

  Just add the number VLAN on the Portgroup.

  Maybe you can do a printscreen with the current configuration?

• Explanations on lawless VMKernel & port management pour network configuration

  Hello

  When my money of VCenter configurations, I understand a little better connections in the VSwitches ports VMKernels and Managements of Port.

  Is this the same chosen?

  Thanks in advance

  Under ESX on was 3 types of ports/network:

  -Console of Service-> dedicated to the administration of the ESX

  -VMKernel: Used pour storage NAS and iSCSI-> allows you to Allocate an IP to the ESX

  -VM Network: Ream pour create the network of virtual machines

  Under ESXi, there is more service Console, everything is now in the vmkernel. 'Network management' is the name given to the vmkernel port created during installation of the ESXi and on which to active the ESXi management

• VMkernel Port Configuration using Powershell.

  Hello

  I was playing in my test environment with the creation of the virtual switches and powerCLI port groups.

  I created a port group VMkernel using the following command line

  Get-vmhost $vmhost.

  new-vmhostnetworkadapter - portgroup VMkernel - virtualswitch (get-vmhost $vmhost------)

  Get - virtualswitch - name "vSwitch1") - 192.168.1.16 - netmask 255.255.255.0 - VmotionEnabled ip: $true

  My question is how can I set the powerCLI VMkernel default gateway?

  I ran the command above on two hosts configured identically using a startup script. On hosts, I get an error message (sorry forgot it exactly) who said something along the lines of:

  Hot migration not enabled for this host, use the following command to active: game-VMHostAdvancedConfiguration-name "Migrate.Enabled" - value 1

  When I watched the Group of ports, vMotion was checked so don't know why this line was necessary. Is this something that I have to run on all hosts?

  Kind regards

  Roger.

  To set the VMKernel default gateway, you use the UpdateIpRouteConfig method.

  Something like that

  $netMgr = Get-View (Get-VMHost  | Get-View).ConfigManager.NetworkSystem
  
  $iproute = New-Object VMware.Vim.HostIpRouteConfig
  $iproute.defaultGateway = ""
  
  $netMgr.UpdateIpRouteConfig($iproute)
  

  I don't know why you're going to the message about the missing advanced configuration.

• How is it that I can ping between ESXi vmkernel interfaces with the sizes of package exceeding the value set in my passage upstream and one located in my vmkernel port group itself?

  
  I have a 10 GB dell powerconnect 8024f the switch and the firmware is OLD, but the port config shows maximum frame size = 9000 to all cable ports

  2 guests ESXi 5.5 wired, build 1331820, put each host computer network is managed by a single port dual qlogic 8150 ANC

  When I connect to my windows VM to check my new 10 GB connectivity (it is configured for jumbo mtu = 9000 frames) and ping-l 8190 against ESXi vmkernel interface that was MTU of 1500, I get an answer without any packet loss... How can it be if the port is configured for only 1500 MTU?  I thought that the two vmkernel port group and vswitch properties must have 9000 mtu defined, it appears that the vswitch properties override the port group properties.

  But I know I must be missing something, a few important concepts, somewhere, because when I connect to ESXi via ssh I can ping devices with values greater than 8190 and not just windows virtual machines that reside on the same host where the ping uses the internal bus, but I am referring to the connections of the host of other ESXi on the switch management.

  In summary - how the VMkernel does ping and response to pings of bigger sizes greater than the value of the switch upstream?   and why do ping with large packets get answers when the vmkernel port group is always set at 1500, is this a bug or is this feature obsolete?   I remember specifically in ESXi5 that I had to configure the vmkernel port group and the vswitch for this property to work.

  Unless you specify "Don ' t fragment" (-f for Windows) you will be able to use any size package successfully.

  For ESXi, take a look at Troubleshooting ESXi Jumbo Frames.

• Nexus 1000v and vmkernel ports

  What is the best practice to put on the nexus 1000v vmkernel ports? Is it a good idea to put all the ports of vms and vmkernel on nexus 1000v? switch or dvs or some vmkernel as management ports must be on a standard?  If something happens to the 1000v, all management and vms will be unreachable.

  any tips?

  Yep, that's correct. Port system profiles don't require any communication between the MEC and VSM.

• VMKernel port group

  Here is the configuration of the network of one of our hosts ESX 4.1:

  (1) the virtual computer network

  (2) Service with 1 IP console

  (3) VMKernel with 1 IP for vMotion and iSCSI, called as VMKernel_iSCI

  I can see there are 4 NICs attached to this host.

  Now, I just know, that same using iSCSI and vMotion VMKernel is not a good practice.

  question 1

  So I would like to know how is the mapping of the ESX host's network. Is this;

  1 NETWORK card = 1 VM Network

  1 NETWORK card = 1 Service Console

  1 card NETWORK = 1 which is currently used for iscsi and vmotion VMKernel port group

  In a standard switch, there are 2 network cards configured.

  2nd question

  I want to delete 1 port VMKernal vmotion (VMKernel_iSCI) and create a dedicated for vmotion.

  I know that I have will require another IP address, but what of NIC, it will be;

  1 NETWORK card = VMKernel_iSCSI

  1 NETWORK card = VMKernel_vMotion

  Please explain.

  Thank you

  Mihir

  From a pure technical point of view, it will work, as long as your network is configured properly (i.e. taking advantage of VLAN and the separate subnets on management, vMotion and iSCSI). However, I am worried about the bandwidth and quarrels with such a configuration.

  BTW. except if you've already seen it, I would recommend that you take a look at http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf

• Loadbalancing VMkernel Uplink for NFS

  Hello everyone,

  I'm organizing a larger facility with ethernet base storage NetApp NFS.

  On the picture you can see my network design. What is the best way to configure vmkernel ports to use the two vmnic (8 and 10)?

  EtherChannel / LACP between host and first switch 'instance' is not possible because the switches do not support this (HP VirtualConnect).

  My fear is that, in my first setup scheduled

  VMkernel Portgroup - > 1 VMkernel (192.168.1.201)-> uplink: vmnic8, vmnic10 (based on the virtual port ID)

  All NFS traffic will pass through vmnic8, without worrying how can stores NFS I use. Or good vmnic8 used for the vmdk file 1, vmnic10 for a vmdk file 2, vmnic8 for the vmdk file 3 and so forth?

  How many times the NFS connection road is calculated?

  Will be 'Route based on the physical load of NIC' work for me?

  Thank you

  Marcel Mertens

  Mehdi says:

  Will be 'Route based on the physical load of NIC' work for me?

  No, it will not help here, it might be useful with virtual switches with many VM and they could be rearranged at certain intervals if necessary.

  How many times the NFS connection road is calculated?

  It will be only once, according to the inner IP routing table.

  VMkernel Portgroup-> VMkernel 1 (192.168.1.201)-> Uplink: vmnic8, vmnic10 (based on the virtual port ID)

  All NFS traffic will pass through vmnic8, without worrying how can stores NFS I use. Or good vmnic8 used for the vmdk file 1, vmnic10 for a vmdk file 2, vmnic8 for the vmdk file 3 and so forth?

  No, it will not use differnet vmnic for different vmdk files. The best way for you would be to create two NFS data warehouses and export through two addresses different IP on different IP subnets. Create two interfaces Vmkernel on the same vSwitch (with a key vmk on each subnet), and then connect them to the vmnic in settings of an active / standby. Do you use two vmnic simultaneously and also provide fault tolerance.

• Why vmkernel port for iscsi and vmotion services?

  Hello

  Just a quick question.

  I was trying to understand - why we need to have a vmkernel port when we want to use features such as vmotion or iscsi.

  Why not use them with a console port service or a port of vm management traffic.

  No particular reason.

  Thank you

  Yes. You're not really all that traffic produced by DRS and vMotion actions in your production (maybe time critical).

• Creating multiple vmkernel ports

  Hi all

  I have a script that will create a vmkernel on each host in turn like that

  1. Create new VMKernel Port in vSwitch0 on each host to student

  New-VMHostNetworkAdapter - $stuSvr01 - PortGroup $vpgName VirtualSwitch - $vs1 - IP 172.19.1.41 - VMHost 255.255.255.0 subnet mask

  New-VMHostNetworkAdapter - $stuSvr02 - PortGroup $vpgName VirtualSwitch - $vs2 - IP 172.19.1.42 - VMHost 255.255.255.0 subnet mask

  This makes the scripts I write long enough that I do a lot of configuration vNetwork.  Is there a way I can create two tables, one with host names and the other with IP information and order custom foreach method is used?  I tried to make it work, but cannot find a way to get the values of the second table.  I tried to put the parameters in a hash table, but I was unable to find code examples for how the reference values.

  Any help would be welcome.

  Why don't you use a CSV file with all the information in there.

  Easier is to use a header line, something like this

  Server,IPaddr
  srv1,192.168.10.1
  srv2,192.168.10.2
  ...
  

  You can then browse all the rows in the CSV file like this.

  ...
  Import-Csv "C:\data.csv" | %{
     New-VMHostNetworkAdapter -VMHost $_.Server -PortGroup $vpgName -VirtualSwitch $vs1 -IP $_.IpAddr -SubnetMask 255.255.255.0
  }
  ...

• Satellite L515-S4960: ESata port can be used for LinkSys WLan adapter?

  Buy Toshiba L515-S4960 laptop, bought a LinkSys RangePlus wireless notebook adapter, but I did not yet find a port to plug in.

  I wanted to extend the reach of the signal from my router.

  The place above the eSata port opens to support an adapter?

  I don't want to tear anything in amont.*

  No, you cannot use the eSATA port for the use of the USB WLan adapter.
  You can only connect compatible external devices that support eSATA port!

  As far as I know a laptop to LinkSys RangePlus wireless adapter is a PC card that supports a CardBUS interface.
  You can use in only in the PC card slot supports CardBUS as well.

  Check you manual use if your computer supports the PC card CardBUS (32 bit) slot.

  Your question is confusing.

  What is the Device Manager has to do with your question?

  You have the printer driver on CD-ROM or downloaded?

  If you mean there is no entry in the drop-down list, as shown in this image: http://screenshots.modemhelp.net/screenshots/Windows_XP/Printers/Add_Printer/03_%28Local%29/01_%28Use_Port%29_%28Select%29.shtml then you need to check the "Create a new port" to create the USB port.  Especially with HP printers, however, it is preferable to use the installation software as HP uses a USB port to measure.

• Which of my sata ports should I use?

  I have this hard drive [http://www.amazon.com/gp/product/B00471G8CC/], but I want to make sure that I use the best sata port. My office is the CQ5720F, here is the link to the plug to motherboard [http://support.hp.com/us-en/document/c02552467]

  He says I have sata 1 and 2 under 'internal connectors' but I have 4 sata ports. That's the problem, I don't know which one to use. Currently, I have it plugged into one marked "Sata 3. What should I do?

  Thank you, Travis

  The specs are incorrect. All 4 SATA ports are the same and are SATA2.0 ports. I doesn't really matter which port you are using, but I put the main hard drive on #1, secondary hard drives on #2 and #3 and the CD/DVD on #4.

• Issues of access to the port noticed when using wireshark

  1. I noticed CDP on wearing my workstation, I could see how this could be useful in using a sniffer to find out which port on a switch, you are connected to. I discovered running on this port without activating cdp avoid advertisements of cdp on port. Most of you turned it off or they leave?  If so is it a company policy to do?

  2. the next strange package race was spanning tree (BPDU?) packets, I saw.  I thought that this is coelio why would you see protocols spanning tree on an access port?  I used the command spanning tree bpudguard suggests that would prevent me from receiving bpdus on an access port.  This did not work, what order you we just to not receive bpdu?

  3. the last one is the one that I find it extremely odd that I receive eigrp Hello of my main switch this switch of access level. The eigrp should just broadcast to other switches running eigrp?

  Hello

  1, it depends. If you have Cisco phones, you have cdp enabled on the interfaces. If you don't use phones, you can disable cdp on the interfaces.

  2, Spanning-tree is a loop prevention mechanism. you want to use the tree covering all the interfaces where a loop can occur. You can introduce loops on the access port if you connect a switch on that port. A switch will always send packets bpdus on access ports unless you specifically configure the switch does not to do this. Spanning tree bpduguard is used to protect a port of bpdu packets. If a bpdu is received on a port with bpdu guard enabled, the port closes because it is an invalid configuration. BPDU guard does not filter packets bpdus on a port. If you want to filter packets bpdu on an interface, you use spanning tree bpdufilter. spanning tree bpdufilter stop bpdu packets sent on an interface.

  3, Hello Eigrp packet are sent on all interfaces enabled for eigrp. To prevent the eigrp packets out all interfaces running eigrp, use the passive-interface command in eigrp configuration.

  Thank you
