• iSCSI and adapter NC550SFP

  Hi all

  I have adapters HP NC550SFP with ESXi 4.1 for an iscsi (10 G, control flow and frames configured) network.

  My configuration is up to now using the "iscsi software map" in vmware... because I see no support for adapter hardware iscsi for these cards. My questions are:

  1 the NC550SFP is supported by a hardware iscsi adapter?

  2 should I worry used with 10Gig iscsi software adapter?

  Thanks for your time... I'm a newbie to iscsi here... so I would like to do things properly before putting them on the prod!

  1 the NC550SFP is supported by a hardware iscsi adapter?
  2 should I worry used with 10Gig iscsi software adapter?

  1. I see iSCSI on the plug on HP, but no confirmation that it is a hardware iSCSI HBA.  It should be appear under storage adapters if she supports the iSCSI hardware.

  2. I don't think you should be concerned.  ISCSI HBA hardware will take off the part of the processing load and overhead of off the VMkernel (CPU and memory).  But you can see the small difference with the new processors and memory that we have in the servers today.

• 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.

• Number of targets for a storage HBA adapter?

  I'm setting up the connections of storage host as below is to say each HBA host with 2 connected to FC switch, which in turn connects to the storage as below: -.

  

  Now if I select the host & go to Configuration-> storage adapters-> select an HBA.

  I can understand the number of paths, it is double since via adapter HBA selected, I have two paths for each data store.

  

  But why target number is 4, even if via this selected HBA adapter there are only 2 paths by the data store and not 4 paths?

  Don't forget that we select one of THEM, so logically it would the target number according to the targets available via this HBA adapter only

  If you have two storage arrays with both SPS on each storage array, then you will have 4 targets:

  Target 1 - Bay storage 1-1 storage processor

  Target 2 - Bay storage 1-2 storage processor

  Target 3 - Bay storage 2-1 storage processor

  Goal 4 - Bay storage 2 - storage processor 2

• iSCSI HBA NIC teaming on recommended vSS?

  Hi all

  Just curious when you have two iSCSI HBAS do not use VMwares iSCSI Software initiator you still need to make sure that the following configs are in place? :

  Vmk1 - iSCSI0 - VMNIC1 - Active

  VMNIC2 - not used

  VMK2 - ISCSI1 - VMNIC2 - Active

  VMNIC1 - not used

  Or can you just leave it as active/active with Orig Port ID?

  There is much info on what to do with the software iSCSI initator but what when you have HBA?

  Yes. I added a link to my previous post which illustrates the configuration.

• Free hypervisor ISCSI HBA

  I'm looking for a hba iscsi which will work without problem and can be which is not expensive.

  Can someone advice me?

  Thank you.

  Yes, either check with the seller (that should know) and also take a look at VMware HCL to http://www.vmware.com/resources/compatibility/search.php?deviceCategory=io to see what iSCSI HBA is taken in charge for the different versions of ESX (i). There are also a couple of network server adapters, which can be used as iSCSI HBA, but some of them do not support frames.

• 10 G of copper iSCSI HBA / NIC?

  Because of vSphere 4.1 support 10G copper iSCSI HBA / NIC? It will support VSphere 5? If it is supported, which it will support?

  I agree with golddiggie on the Intel stuff.  There are cards that work well, you can also search the forums here some of the brands and models to see what problems people have met with them and the possible configuration changes that can help.

  If you have found this helpful at all prices please points using the correct or useful!  Thank you!

• iSCSI HBA + SAN, EqualLogic

  I have a new deployment, I plan.

  I'm looking at a PS6000VX EQL - dual controller with 4 x GBIT by controller cards. In my opinion, it works in an active/passive configuration.

  What is worth of watching me iSCSI HBA with this sollution? Cost is not a problem at all. Performance/reliability/redundancy is.

  I understand with HBA you can multi-path, but with a sollution active/passive is not treated by the table flipping? In that it switches IP on assets of Eve? (with equallogic?)

  Any comments?

  Do you have more information in this plugin MPIO?

  Is still in beta... so there is no official information.

  But will probably like the MPIO module for the Microsoft iSCSI initiator (which can use all the links on the active controller).

  There will be a big reason to go with the software on a HBA iSCSI initiator?

  It's cheaper

  And you can license to have the company more

  understand my reading that Equallogic doesn't have any special configuration as the SP manages failover.

  Right.

  Just remember to follow the proposed (by Dell) network topology if you use two switches (instead of a main switch with 2 stacked modules).

• adding targets to send the iscsi hba software.

  Hello

  I am trying to add dynamic send targets to a host ESX 3.5.  Here is the code I wrote, but there is something wrong with it.  Someone at - it worked with this before or would be able to tell me where I'm wrong?

  Thank you

  Matt

  Here is my code:

  My $iscsisvr = Opts::get_option ('iscsisvr');

  My $hostview = Vim::find_entity_views (view_type = & gt; "HostSystem");

  My $host_ss = Vim::get_view (mo_ref = & gt; $hostview - & gt; configManager - & gt; storage system);

  My $host_sv = Vim::get_view (mo_ref = & gt; $host_ss - & gt; storageDeviceInfo);

  My $host_hbaview = Vim::get_view (mo_ref = & gt; $host_sv - & gt; hostBusAdapter (bus = & gt; "32", device = & gt; "vmhba'));

  My $sendTargetSpec = HostInternetScsiHbaSendTarget - & gt; New (address = & gt; $iscsisvr);

  My $addSendTarget = AddInternetScsiSendTarget - & gt; New (iScsiHbaDevice = & gt; "vmhba32", target = & gt; $sendTargetSpec);

  $host_hbaview - & gt; HostInternetScsiHba (configuredSendTarget = & gt; $addSendTarget);

  Find one or two things:

  Probably, you won't need the storageDeviceInfo unless you want to verify that the iscsi HBA is configured (which may not be).  You also do not get a view of the hostBusAdapter.  You must remove that as well.

  You can delete the following text:

  my $host_sv = Vim::get_view(mo_ref => $host_ss->storageDeviceInfo);
  my $host_hbaview = Vim::get_view(mo_ref => $host_sv->hostBusAdapter(bus => '32', device => 'vmhba'));
  

  There was a spelling error in AddInternetScsiSendTargets (you have it as AddInternetScsiSendTarget).  In addition, this method is off your HostStorageSystem, in this case, $host_ss.  You need to perform a rescan after adding the target as well.

  Change:

  my $sendTargetSpec = HostInternetScsiHbaSendTarget->new(address => $iscsisvr);
  my $addSendTarget = AddInternetScsiSendTarget->new(iScsiHbaDevice => 'vmhba32', targets => $sendTargetSpec);
  
  $host_hbaview->HostInternetScsiHba(configuredSendTarget => $addSendTarget);
  

  TO:

  my $sendTargetSpec = HostInternetScsiHbaSendTarget->new(address => "$iscsisvr");
  $host_ss->AddInternetScsiSendTargets(iScsiHbaDevice => 'vmhba32', targets => [$sendTargetSpec]);
  $host_ss->RescanHba( hbaDevice => "vmhba32");
  

  I would probably change your code to something like the following:

  sub FindVmhba32
  {
       my $HBAs = shift;
  
       foreach ( @{$HBAs} )
       {
  
            if ( $_->device eq "vmhba32" )
            {
                 return $_;
  
            }
       }
       return undef;
  }
  
  my $host_ss = Vim::get_view(mo_ref => $host_view->configManager->storageSystem);
  
  my $host_sv =  $host_ss->storageDeviceInfo;
  my $vmhba32 = FindVmhba32($host_sv->hostBusAdapter);
  
  unless (defined $vmhba32)
  {
       Util::disconnect();
       die "Failed to find ISCSI HBA ('vmhba32')";
  }
  
  my $sendTargetSpec = HostInternetScsiHbaSendTarget->new(address => $iscsisvr);
  $host_ss->AddInternetScsiSendTargets(iScsiHbaDevice => 'vmhba32', targets => [$sendTargetSpec]);
  $host_ss->RescanHba( hbaDevice => "vmhba32");
  

  You can drop the FindVmhba32 subroutine and simply use a block around the AddInternetScsiSendTargets eval.  You can throw a few errors, one of them is not found if the specified HBA is not found.

• ISCSI HBA con problemas y el failover

  Is.

  Tengo el the siguiente problema: tengo UN IBM BladeCenter, in sus hojas tengo una an ESX 3.5 con una controladora iSCSI HBA DOUBLE. Por otro lado UN IBM DS3300 iSCSI storage con doble controladora.

  CONFIGURADO siguiente manera:

  A HBA port - 192.168.3.60 & gt; switch 1 & gt; SPA_NIC1 - 192.168.3.53 - SPB_NIC1 - 192.168.3.55

  B HBA port - 192.168.4.61 & gt; switch 2 & gt; SPA_NIC2 - 192.168.4.54 - SPB_NIC2 - 192.168.4.56

  Development the situation ahora y el problema.

  Having esta config tengo cuatro paths o caminos hacía las del LUN storage.

  Ahora el problema.

  If switch 1 (simulando una caida) apago El el failover happens sin problemas y los caminos increasing an el use switch 2. Hasta ahi esta in orden, don't sin embargo, cuando todo is restituye the led unit switch 1, el ESX no vuelve a ver estos caminos, por lo tanto if only una caida en el switch 2 the unit total seria perdida. Esto sucede tanto if the fixed esta o en MRU failover policy.

  The unica manera por the black recover esos switch paths led back 1 are doing UN Scaneo las LUNS. Sucede lo mismo so the caida is da en el switch2.

  MI jerking that're esos caminos is recuperen automatically cuando vuelven a estar activos, y currently only en indefinidamente "DEAD."

  The Plaça HBA are una QLOGIC 40xx.

  The question are so estoy cometiendo algun error config o tr por el contrario en is debe realize algun seteo para a nivel del ESX as chequee los paths.

  Gracias a todos.

  Buenas ElGogy,

  The "problem" is in the telephone box, todo lo demas esta Ok. Cabina give en dicha HCL y luego the quitaron y luego volvieron a poner. Finalmente esta con admitida ESX > = 3.5 y solo con Software initiator. (Played a look has the HCL ahora are easy con search: http://www.vmware.com/resources/compatibility/search.php?action=search&deviceCategory=san&productId=1&keyBasic=ds3300&maxDisplayRows=50&key=ds3300&release%5B%5D=-1&datePosted=-1)

  Fijate tambien in communities of las este thread of: http://communities.vmware.com/thread/121802?tstart=0&start=0

  Of todas formas as you creo La cabina esta running OK. El con las DS of ESX behavior are MRU, aun if usar el pones o no el fixed en ESX (the da igual has the cabina.). Este behavior is lo Indica has the 'lun to host mapping' pones en cabina cuando LNXCLUSTER el. (that are that hay than poner lo).

  Cabinas are Simplemente no tienen el failback automático. Supongo as lo hacen para avoid errors: If a cae switch, mejor you criteria y requiera manual attention stink if no dock than a switch could what's cae y is levanta todo el rato (fallos momentaneos en the conexion, fallos electricos in bucle, o firmware aleatorio, fallo x ej,) would be doing that el cambie rising path, no're lo mejor del mundo.

  A saludo y espero you sirva!

• iSCSI HBA on 3.5 U3 - vswitch installation is required

  I have ESX 3.5 U3 installed on an IBM 3850 with 2 QLogic is installed.  I did the firmware updates and ESX recognizes the HBA as storage adapters.  My problem is this, all my other ESX servers use standard NIC so I create a second vswitch for my iSCSI LAN and add 2nd NETWORK card for guests of this switch.  When I go to create a my vswitch iSCSI only available adapters are my cards, I can't add the HBAs.  How can I configure a vswitch on my iSCSI LAN that will be using / accessing the HBAs?

  If you use the initator MS iSCSI inside your virtual machine then you will need to use regualr NIC you wouldn't be bale to use iSCSI HBAs as they are used by the vmkernel to access the iSCSI SAN

• iSCSI HBA Mapping?

  Hi people,

  I recently updated my servers to two HBA ports. I plugged in and this through the configuration, and they are all in a race. But in the journal, the configuration is slightly different, and I don't know what the right/best.

  Here's a picture to view the configuration...

  

  To be honest, I don't really understand the discovery thing static/dynamic. A primitive test seem to fail at the top of ok in the following scenarios:

  1. a the HBA port is unplugged

  2. If a controller is removed from the San.

  Can someone sched all light/thoughts/feedback on this configuration?

  I would make two identical configurations, but don't know which one to use.

  According to the scenario of DS3300 configuration to improve performance, it is better if the two controller using a different IP subnet.

• When to use the ms iscsi software adapter

  When should I use a vmware disk or using ms iscsi initiator software to point to volumes?  People will usually switch to a certain size of disk?

  Hello.

  2 TB - 512 bytes is where you should start thinking about your options.  If you want a VMFS volume larger than 2 TB - 512 bytes, then you must watch the scopes or dynamic disk inside Windows options.  One of the biggest advantages of using the initiator iSCSI MS is that it is similar to the use of RDM - you can move them around much easier than with VMDK.  For me, it comes down more to the operation and management of the system to a particular size but.

  Good luck!
