• Installation of physical switches for ISCSI traffic

  Is that all I need to know from a networking perspective to configure ISCSI switches dedicated to support my ISCSI SAN on the left?

  I do not plan on switches connected to the prod network. I only plan on using these switches for ISCSI traffic.

  LeftHand supports LACP, if your supprt of switches that you should consider using the trunk mode. In my SAN P4300, I have two 3750's stacked. Each SAN node will connect to each switch and is located in a LACP/etherchannel link. All this is condensed to a single virtual IP address which is presented to ESX/i. don't forget to create a vmk for each dedicated vmware iscsi connection and bind according to this pdf.

• ESX iSCSI Configuration recommendation

  Hello

  I wonder what is the best configuration of the storage card in the following scenario to provide a NIC host and SAN controller redundancy. The SAN must be directly connected to each host that I don't have one at the moment gigabit switch, which means each link point to point in its own subnet as below.

  Host 1:

  iSCSI_A1: 192.168.1.2/30

  iSCSI_B1: 192.168.1.5/30

  Host 2:

  iSCSI_A2: 192.168.1.9/30

  iSCSI_B2: 192.168.1.13/30

  ISCSI SAN:

  A1 of the host: 192.168.1.3/30

  B1 the host: 192.168.1.6/30

  A2 of the host: 192.168.1.10/30

  Host B2: 192.168.1.14/30

  According to the article, VMware KB: considerations for use port binding software iSCSI in ESX/ESXi, I should not use links in Port because each link is in a separate broadcast domain. Does this mean that I have to put up 2 iSCSI adapters on each ESX host software and just use the dynamic discovery?

  Thanks for any help.

  Of course, no problem. Make sure you see both paths, under Configuration-> storage adapter-> select your iSCSI adapter. Example like this. In this case, I have 12 aircraft 24 channels, so 2 paths to each device (LUN).

• Dedicated switches for ISCSI switches dilemma...

  Hello

  I bought two dedicated switches (I thought they were in any case) for ISCSI traffic that I had planned on just my ISCSI traffic from 3 dedicated ESX host connection.

  Now the network team is said it opened enough ports on switches from my heart for the IP traffic such as vmotion, machine VM... etc.

  How can I use the new switches that I bought for ISCSI traffic only, to include also the IP traffic, but everything in remaining secure? I would do that with the VLAN?

  If so, how would I go on this subject?

  I would use VLAN for that. Trunk at the bottom of the ESX host and dedicate and label your ports vmkernel or groups of ports.

  Example:

  vSwitch0 with -

  iSCSI: vlan 5

  VM traffic: vlan 6

  VMotion: vlan 7

  Configuration:

  VMkernel port ISCSI0, vmk1 tagged vlan 5

  Port group VM-traffic, the tag vlan 6

  VMkernel por vMotion0, vmk2 the tag vlan 7

  Regarding safety, it depends on your needs. You can always leave the VLAN iSCSI and vmotion again according to the requirements of connectivity to other systems.

  Something like that can work?

• Need suggestion for storage on the server ESXi5 iSCSI configuration

  Hi friends,

  I am new to vmware & I want t know if I have physical iSCSI card installed in my ESXi 5 & it connect directly to the server and then again I want to configure virtual SCSI for connection to the VM card? If so, why?

  Thank you and best regards,

• ISCSI configuration

  Hello

  I'm initiator configuration iSCSI on my ESXi 5 host software. I use the Dell PowerEdge r.620 server.

  How are iSCSI Broadcom cards will be copied into the storage card from vCenter Server view.

  At the moment I am unable to see any adapter storage Broadcom for the "storage card". I did all the steps below.

  (1) VSWITCH CONFIGURATION

  (2) standard vSwitch Configuration

  (3) add the VMkernel iSCSI Ports

  (4) ports VMkernel associated with physical cards

  But I am unable to see the storage card BroadCom for the "storage card".

  Please suggest.

  You won't see this map appears in the list of storage adapters. It is listed in the HCL as network.

  

  Enable iSCSI Software adapter, get properties for it in the list of storage adapters, and then configure the networking from there.

• How data travels in the iSCSI Configuration

  

  Hello

  I'm a little confused about how DATA moves through an environment of VI3.5 using iSCSI SAN.

  Before, I am attaching a schema, so everyone will be on the same page.

  It is a scenario with two servers ESX (ESX1 and ESX2), a physical server (Server1) and 4 Virtual Machines. (VM1 ~ 4)

  vmnic0 is for traffic Service console and the virtual machine.

  vmnic1 is for vmotion, but on the same subnet that are Virtual Machines.

  vmnic2 and 3 are for iSCSI and Service console for iscsi on a different subnet and different switch.

  The example is for the understanding of the performance and the communication network and not for security reasons.

  I know that when you want to use VMotion and HA, you need to use Shared Storage (IE iSCSI SAN) and your virtual machines are stored on the SAN.

  Here are my questions:

  1 - is this correct design?

  2-if I want to copy a VM1 VM2 to file, how data moves? (knowing that both are stored on the same SAN and they are both on the same ESX Server)

  3-if I want to copy a file from VM1 to VM3, how data moves? (Knowing that both are stored on the same SAN but they are on different ESX servers)

  4-if I want to copy a file to the server Server1 to VM1, how data moves?

  5 - If you do a VMotion VM1 from ESX1 ESX 2, how data travel? (I know for VMotion the contents of the RAM to the virtual computer will be copied to the second serve of ESX) This will affect the performance of the local network?

  6. What do you recommend to monitor traffic on vmnic?

  Please include the question number in your response.

  Thank you

  1 - is this correct design?

  OK for iSCSI.

  But you do not HA hat on the breakdown of the network cable or the NETWORK card (for the first 2 vswitches).

  It is good to have iSCSI separated by VM and VMotion, but usual for each vSwitch to give at least 2 cards of uplink.

  You can for example put VMotion and VM on vswitch, using 2 NICs and affecting a NIC preferred for the virtual machine and a preferred (different) for VMotion NETWORK card.

  2-if I want to copy a VM1 VM2 to file, how data moves? (knowing that both are stored on the same SAN and they are both on the same ESX Server)

  VM1 and VM2 could talk via the network of the VM.

  So VM1 get data from the vmknic2/3 (if is not in the cache of the comments), copy to network (vmknic0), VM and then store the data (and goes to vmknic2/3)

  3-if I want to copy a file from VM1 to VM3, how data moves? (Knowing that both are stored on the same SAN but they are on different ESX servers)

  Same as before, using 2 ESXs

  4-if I want to copy a file to the server Server1 to VM1, how data moves?

  vmknic0, then vmknic2/3

  5 - If you do a VMotion VM1 from ESX1 ESX 2, how data travel? (I know for VMotion the contents of the RAM to the virtual computer will be copied to the second serve of ESX) This will affect the performance of the local network?

  vmknic1

  6. What do you recommend to monitor traffic on vmnic?

  You can use the tab Performance on ESX.

• Newbie on iSCSI Configuration questions

  Hello everyone

  I'm new to VMware. I have two questions

  (a) once I have add an address IP of SendTargets discovery, how can I update it? for example, if a new target is visible via the IP discovery after that it has already been added in VMware and I want it to appear.

  (b) is there a provision the disconnection of one specifying IQN (San identifier)? I went though VSphere Documentation and I couldn't find anything.

  (c) VSphere he iSNS support such as Linux (iscsiadm)?

  Thank you

  Welcome to the Forums-

  (a) you will need to go to the section of the configuration of the ESX host storage card in the client vSphere select initator iSCSI, then click Rescan - this cause a target command send sending sllowing to the discovery of new targets

  (b) No, there isn't a way to disconnect from a specific IQN I know

  (c) to the vSphere, I think not vSphere supports iSNS.

  If you find this or any other answer useful please consider awarding points marking the answer correct or useful

• How many switches must be configured and min no network interface cards?

  Hello

  We will implement the ESXi5.0.

  We would like to know if we use different ports for network management and vMotion groups?  It seems that two of them use the same (different from ESX 4) IP address.

  In addition, my supervisor would like to know what is the minimum number of network interface cards to use (because the server has no slot PCIe)?

  Your opinion is requested.

  Thank you

  Since we implement VLANS on our site and based on the documentation, ESXi 5 gets only 1 battery IP, wonder what is the best way to cope.

  It is true that ESXi has that one battery IP, which is very good compared to the other two in ESX (Linux in the Service Console and the Vmkernel). However, we have only an IP stack means that it is the same driver tcp/ip, but does not mean that we cannot have multiple IP addresses.

  For example, you can create a Vmkernel how many interfaces you want and assign different IP addresses, which could be on the same network or on different.

  Even if you don't have a VLAN in your environment I would still recommend using another IP network for vMotion for your management. This will make the two a little more 'best practice', easier to different and you would be good too preperred if you implement VLANs in the future.

• Update the Configuration of the switch switch 2.1 Executive to 3.5

  Hello world

  I tried the switch 2.1 update Executive to 3.5 and have known, that my configurations have stoppped working. To me, it looks like 3.5 dislikes my IVI configuration for switching modules.

  The function check in MAX tells me that the PXI cards are not available. The first page of the configuration of the switch shows no configuration / terminal blocks.

  Because the configuration consists of nine matrix with lots of report cards, I would really appreciate a way to properly import the old configurations (xml files are available)

  Any ideas?

  See you soon

  Oli

  Hi Oli,

  Yes, there was a major change in the Switch Executive 3.5 - it now uses for switching NI DAQmx calls material. There is a KB document the upgrade process a simulated configuration from an earlier version, but of course, you can try the steps that make sense, too:

  Import of NI Switch Executive 3.0 and previous virtual devices in OR Switch Executive 3.5 and later versions

  http://digital.NI.com/public.nsf/allkb/1D1099A85B156FA68625778500787444

  However, I have noticed that the KB Editor uses a configuration file to .txt instead of the .xml you have. I see two options here: first of all, if you have even an operating system with Switch Executive 2.1, you could probably export settings in the form of text or you can try to modify the .xml file manually to resemble the layout of the text (probably a lot of work, you would have to learn the structure of the text by trial and error using newly created Switch E.g. 3.5 configurations...)

• IviSwitch loses value when sending, "configure the switch" configuration = TRUE

  Hi all

  We are currently assessing Teststand 4.1 with a multimeter keithley 3706 switch system.

  After a first enthusiasm, thinking this tool with the meter switch fits perfectly our needs, real life seems difficult.

  Between several other problems, we must say to the device, the channel "s1com1" and "s1com2" are strings of configuration.

  Configure the teststand step: change the switch step IVI-> IVI, switching, configuration switch: channels "s1com1" Configuration = True

  led to observable in both actions in Ni Spy:

  GetAttributeViBoolean (..., "s1com1", _IS_CONFIGURATION_CHANNEL, VI_FALSE)

  SetAttributeViBoolean (..., "s1com1", _IS_CONFIGURATION_CHANNEL, VI_FALSE)

  manually call to this function of the interactive a CVI fp class works as expected (the VI_TRUE updated)

  Is there any hint that we could do wrong? Currently, we are just before writing wrappers in cvi and jump all the wonderful Types of IVIStep in teststand.

  Looking forward to any comments

  David-

  This would have the same problem we discovered recently in our internal tests. For the problem that we found, we will probably include our fix in a next corrective patch. You can check if the problem persists if you change your locale in English in the control panel? If the problem no longer occurs, can you use this as a workaround for now?

• Try to set up a channel port to connect a new switch with ports that were previously configured... error

  I have s60 stacked switches.
  OTF version 8.3.3.7

  I try to add a 2 port channel interface, nothing fancy, but I keep getting errors due to the already switch that is configured as a switch on a port vlan by default.

  When I run command "no switchport" on one of the 2 interfaces I get this error

  "error: IM 2/36 port belongs to a VLAN by default.

  When I try to add interfaces port-channel I get this error

• Multiple Configuration LAG switch

  -5-6224 switches with NO active ROUTING

  -1 5 switch acts as a LAG switch that I've got (2) port GAL from the other 4 switches in the single 6224.

  -L' single switch containing any other LAG switch is configured with (ACCUSE respectively CHANNELS 1-4).

  -All non - LAG ports are configured as members not tagged VLAN 10 and OFFSET channels are configured in GENERAL VLAN add 10 TAG all along.

  When we try to get the switch several ports configured in a SHIFT in a single switch, do I have to separate the port-channel number or I would be able to create a single port for all of the 10 Channel VLAN between all switches?  I get a few intermittent results when you set up the laboratory of the switch and I'm still not comfortable with the config where goes.

  Hi jimbennin,

  Each LAG switch should be its own channel LAG. You must have 4 different channels of LAG. LAG is essentially to create a virtual port on several ports.
