Software iSCSI or Broadcom HBA w/TOE?

• iSCSI iSCSI Software adapter or Broadcom adapter?

  This is a bit of follow up a thread on a previous post. But I noticed that my BL490c G6 5 hosts have a software adapter and Broadcom iSCSI adapt. Although I have nothing under Broadcom cards.

  Is there a difference in performance between these two? In my head, material should be better than software, but it seems software as default.

  I found this KB, indicating he may be some Fiddlers involved to get ESX to use Broadcom cards, but is it useful?

  The iSCSI SAN is a StorageWorks P4300 G2.

  The BCM5709 equivalent and can slightly reduce the amount of work the CPU has to do, but does not support Jumbo Frames.

  If you are network switches or a table do not support frames then using the capabilities of unloading of these NICs is good.

  If frames Jumbo is supported by the two switches and table so it is best to use the iSCSI HBA software.

• 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

• ESX 3.5i / software iSCSI?

  I plan on upgrading a cluster of ESX 3.02 tomorrow to ESX 3.5.

  I would use 3.5i because of its lack of a service console, we had some problems in the initial Setup, getting the iSCSI traffic because we have an iSCSI subnet separated from our hosted customer (who is on 192.168.x.x network).

  Although I am quite familiar with 3.5i - I still try to use the software iSCSI with this version.   Can it be done?

  Sven

  It should work without problem.  You will need to create a separate vSwitch for the iSCSI network with a kernel port assigned to the iSCSI IP address range.  You will also ensure that iSCSI is allowed through the firewall.

• 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!

• No storage found on material support iSCSI cards Broadcom BCM7509C

  ESXi 5 with a port dependent on iSCSI hardware cards Broadcom BCM7509C

  Config done by the book- http://www.VMware.com/PDF/vSphere4/R41/vsp_41_iscsi_san_cfg.PDF

  I enter the address of dynamic discovery & can instantly see the correct targets in the static discovery tab, but during the execution of rescanning NO devices are

  Also, as iSCSI networks are completely isolated it didn't need a gateway, yet VC5 does NOT authorize the entry 0.0.0.0 to complain:

  The gateway IP address is incorrect. Enter a valid IP address

  It is surely not good?

• 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!

• 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.

• 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?

• Hardware ISCSI does NOT work but the software ISCSI works...?

  We have a HP MSA2012i ISCSI SAN and our ESX hosts are DL380 g6 with dual-port HBAS (Qlogic QLE406Xc) were also running ESX 4.0 and vCenter.

  I can see the cards under my storage adapters, but when we do an ANALYSIS of new LUNS they do not appear. We checked it wasn't a problem to switch by plugging directly on the MSA modules.

  Also, I went in the HBA BIOS and did a scan "for devices" and nothing comes up.

  I found the next thread that describes exactly the issue im having except that everything ive tried they describe does not work for me...

  http://communities.VMware.com/thread/221303

  What Miss me?

  Very well. Have you tried to use the Qlogic iSCLI utility to resolve the problem? You can download the vmkernel corresponding to the new analysis journal? Thank you.

• How to use 4 x 1 GB for software iSCSI NETWORK interface card.

  Hello. I have a HP P2000 G3, with iSCSI connections 4 x 1 GB. I have 4 free 1 GB NIC on my 5.5 esxi server. IM wondering how I could put things upwards, so it would use iSCSI 4x1Go at the same time, so I would get a 4 Gbps to my SAN connection. Is this possible? I read something about iSCSI multi-trip and Port binding, but is all a bit confusing. It seems to me which is used for failover? I tried to put in place using a multipathing guide and got to the top and his display I 8 paths to my SAN, but it seems that a NETWORK adapter is used when considering my switch activity.

  Any help would be appreciated.

• Initiators of software iSCSI Microsoft Cluster in guest

  Hi guys

  I have a client who have iSCSI Storage... now they want to create a cluster, but I read that only FC SAN is supported for RDM...

  but it seems that iscsi is supported as iscsi in guest...

  If someone knows the configuration for this?

  or is it as simple as:

  1. create iscsi volume of Quorum

  2. create iscsi for data volumes

  3 activate the iscsi initiator in Windows 2008 guest VM

  4 map these to W2008 VM iscsi volume

  5. create an another PortGroup-VLAN for the private heartbeat (is it necessary or the private sector can take thje same segment as the notrmal network)?

  Thank you very much

  Oh, sorry I didn't answer your original question.

  You are right, you must configure the virtual computer with 3 vNIC on 3 different subnets, then make sure that the public network is on top, when configuring the network order in the BONE (don't know where it was in 2008 for Windows, in Windows 2003 is configurable in the advanced network settings) Guest.
