ESX 3.5i / software iSCSI?

• Software iSCSI or Broadcom HBA w/TOE?

  ESXi 4.1 loading on 3 Dell R710.  ESXi is picking up the 1 GB Broadcom 5709 as material hba, however nothing I tried helped me activate frames.  When I implemented the hba with frames and make a new analysis, he will not come to the MD3000i LUNS.  (The 3000i detects the hba and I added to the host in the iscsi handler... still no joy at the end of ESXi.  Also I configured ports on the 3000 to accept the extended frame).  If I leave the mtu to 1500, everything works well under hardware iscsi.

  When I use the software initiator with the same NETWORK card, I can activate frames.  (Documentation is ESXi confirms that for the Broadcom, it supports IPv6 and jumbo frames, but you can't blame a guy for trying).

  My question: which would give better performance?  Should I use the material hba without jumbo frames to reduce the load of iscsi, or configure software iscsi with frames?  If I understand correctly, the iscsi software has been greatly improved if I'm not really sure which way to go.

  (I posted this question at the end of another thread and received no bites so I thought I would like to transfer as a new question.)  I apologize.)

  As you discovered, you can really change the MTU on the HBA Broadcom adapters.

  Performance is always difficult to answer.  Of course, the biggest advantage of Broadcom cards is improvement in the effectiveness of the CPU.  There are benefits to this.  Also, realize that the initiator iSCSI ESX and initiator of Broadcom can saturate a link of 1 GB for block sizes more that are useful, even in the absence of the frames.

  So if you are looking for CPU efficiency, for the most part, the block sizes, the Broadcom card will use less CPU host for the same flow as the frames with the initiator of ESX.

  If you are looking for a pure flow, both can fill a wire for large block sizes, and which does not change much with the introduction of jumbo frames.

• Software iSCSI configuration

  Where we get number IQN that we need to manually enter static configuration of the software iSCSI discovery.

  It depends - some have the ability to not be discovered. Give it a try, in case of doubt. If this does not work, then you will need access to the management interface or know someone who can.

• Is there a way to remove the software iSCSI 10W?

  Hello

  We have helped the software iSCSI adapter, add 'Vitrtual Switch' and 'Port group' for iSCSI testing.

  Now, we have already deleted the virtual switch and would like to know if it is possible to remove the software iSCSI adapter?

  OR Alternatively, we can leave the adapter software there without deleting?

  Thank you

  You can remove the software iscsi adapter by disabling everything first. Under the SWiscsi adapter > properties > configure > disable activated.

  After that, the server will request a reboot for the change.

  After this restart, swiSCSI adapter would have been automatically deleted.

• How to add the software iSCSI adapter in vSphere, ESXi 5.0?

  Hello

  Please give me the steps to add the software iSCSI adapter in vSphere, ESXi 5.0.

  Thank you.

  Hello

  In an earlier version of VMware ESXi software iSCSI adapter was included in the list of the storage card, but is not in the case of VMware ESXi 5.0. In ESXi 5.0 iSCSI adapters are not listed by default and must be activated first before we go away from configuration.

• find the number of map software iscsi vmhba

  Hi, im trying to write scripts for automation but I find on different server models the software iscsi adapter varies from vmhba32 to vmhba39

  Is it possible that I can find that number using powercli so I can put it as a variable to be used for another command later in the script?

  Thank you

  Forget the bug with iscsi.

  It's the derivation

  $esxName = 
  (Get-VmHost $esxName).StorageInfo.ExtensionData.StorageDeviceInfo.HostBusAdapter | where {$_.Model -like "iSCSI Software Adapter" -and $_.Status -notlike "unbound"} | Select Device

• Implementation of electronic networks for ESX 3.5 with iSCSI?

  Well, I'll have a bit of a problem here...

  I have 3 VLAN:

  ID

  1 - network management

  2 - iSCSI network

  3 - production or Guest OS Communication LAN

  I can't figure out how to get properly configured ESX or something because my iSCSI storage is not being discovered. Can someone guide me on how my network cards should be configured? I have 6 network adapters and possibly their sticks, but for now I wanted to 1 for ESX management, 1 for iSCSI and 1 for the virtual computer network if that makes sense. If there is a better please let me know, but I defnitely want to configure my iSCSI is own VLAN (2). I have been through a few docs and can't make it work... Thank you...

• several software iSCSI initiators

  Hello

  I have not heard that someone does this, so just to make sure: is it possible to connect two or more without an ESX host? As far I knew each SAN would require its iSCSI initiator, but I only know how to activate the default initiator and not add multiple.

  Thanks for your reply,

  -Rainer

  Yes, it is possible to connect multiple iSCSI targets to the iSCSI Software initiator.

  Create several VMkernel ports bind to the iSCSI initiator.

  • Connect vmhba34 to vmk1: esxcli swiscsi nic add - n d vmhba33 vmk1

  • Connect vmhba34 to vmk2: esxcli swiscsi nic add - n vmk2 d vmhba33

  • Check the configuration of vmhba34: esxcli swiscsi nic list vmhba33 d

  • Vmk2 and vmk1 should be listed.

  It is normally used to provide multiple active paths to iSCSI storage.

  You can also create additional VMkernel ports for more than one iSCSI SAN network.

• ESX 3.5 and iSCSI LUNS

  Good so I'm setting up my servers ESX using iSCSI LUNS.  I do not have the LUN in a VM, I want the servers to use.  Is it possible to do?  And how can I do for that implemented?

  Scott

  You must enable initiator initiator or software hardware

  If you go to the inititiator of the software, you must enable on each ESX host, by going to the configuration of the VI Client storage adapter tab. (you will see something like vmhba32, activate it)

  Once it is enabled, you must add your target (as we are talking about software initiator, it supports only dinamic discovery).  Recommendation, isolate the network cards that will connect to the iSCSI network.

• The list and install the VIB on ESX 4.0 software?

  I recently installed HP Offline bundle on a single host ESXi 5.  It was quite easy - SSH to host the execution esxcli vib software list to see what VIb are installed and then run software esxcli vib install... to install the required VIB.  Pretty easy.

  So I have a 3 running ESX 4 (no esxi) cluster host that I thought that I would setup the same beam offline HP on.  So I SSH to a host and list of vib esxcli software running to see what is already on the host computer and he says that the (software) namespace is not valid.

  What is the comparable command to what are the options in the list are installed on the ESX 4 hosts and how can be installed VIb?  And yes I know I should upgrade these ESX to ESXi hosts.

  Thank you

• Link to maps software iSCSI NIC vmkernal and the vsphere client

  Hello

  IM playing with our VMware 4.1 hosts a Dell Equallogic PS4000E, connection

  So far, I have:

  Created ports VMkernal

  Apply adapters

  The iSCSI initiator enabled

  But apparently, I need to run the following command to bind the ports of iscsi software adapter:

  Add an esxcli swisscsi nic - n vmk # vmhba d #.

  Is anyway in the Vsphere Client?

  Hello.

  Unfortunately, there is no way to do it from the vSphere client.

  Good luck!

• Overhead costs with software iSCSI vs NFS?

  If you use NFS to store your VMS VMDK files, could say nothing about the CPU above for this, compared to the iSCSI Software?

  If you use the FC or iSCSI hardware, it seems, most of the work could be discharged at the HBA, but what about NFS that needs to be done in software? It will be easier that iSCSI from the Vmkernel doesn't have to manage the lower block level access?

  Hello.

  The difference is very small.  Check out the white paper of comparison of the performance of the Protocol storage in VMware vSphere 4 .

  Good luck!

• 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.

• Software iSCSI questions

  I have configured my Clariion CX3 for iSCSI.  It is configured to use CHAP but also require initiator authentication.

  My vCenter 4.0 Update 1 but the ESX host, what I'm trying to configure for iSCSI are 3.5 u5.

  I have installation vmKernel another to use for iSCSI.  I click on properties, select the iSCSI, click dynamic discovery and enter two IP addresses for my CX3.

  When I click the CHAP back under the general tab 'Use CHAP' button, and then select check box "Use initiator name.  I then enter the CHAP secret that I entered on my CX3.

  Can I get a popup saying "Impossible to update the properties of authentication.

  Thoughts?

  If enabled two-way authentication you make sure that you disable CHAP on both ends.

• Error in adding an iSCSI LUN - use software iSCSI initiator...

  Hi guys,.

  I can't add an iSCSI LUN to my host ESX4.0. It is the iSCSI Software initiator that is activated and I can see the LUN after I launch a new analysis.

  While adding the LUN as a data store, it throws me an error, please find the attached for the snapshot file.

  The real question is if I add a lun iSCSI and then remove it and again try to re add it whether or nor the old signature are found that do not readd it.

  Is there a command that I can use to remove all the LUNS already assigned and delete it existing signatures.

  Let me know guys if the above is not clear.

  Kind regards

  Use fdisk to create a partition and vmkfstools - C command to format the partition as VMFS. You use a supported storage array?
