several software iSCSI initiators

• configuration of several hardware iSCSI initiators

  I have 2 qlogic iSCSI intiators in my 3.5.4 ESX Servers I need to connect to an iSCSI target in a redundant configuration. With the vSwitch network connections it is simple enough, create a vSwitch and group all interfaces NIC that you want to use for this vswitch. The network layer deals with redundancy and load balancing. With iSCSI software initiators, it looks like using the vmkernel from what I've seen in the SAN configuration guide.

  Each hardware iSCSI adapter seems to have need it is the own address IP etc... How can I set up redundancy and load on 2 separate hardware initiators balancing?

  Initiators of material are a little different, because they have a BIOS configuration aspect as well.  If you want to boot-from-san configuration, you must configure your initiators with their hw bios and set the IPs and the targets and LUNS to boot from BIOS hw.  With other than the boot LUN LUN, they are configured in the same way as the initiator of the sw.  Each card will be visible in the section storage cards.  You access this configuration and configure targets and LUNS on each.  Once you do this, you will see the same LUN via multiple paths, ESX will recognize the LUNS as separate for the same LUN paths and redundancy is achieved.  If your San is active/active, you can split manually which LUN will be accessible through which HBAS and load balance like that.  You will still need the vmkernel port in your vSwitch as the initiator of the software, but instead to simply configure the initiator sw 1, you configure both your HW HBA.

• Question on the iSCSI initiators and several NIC

  I read the attached document.

  The document speaks to create more iSCSI initiators to talk to the SAN (I understand this bit).

  Page 15 step 4: VMkernel Ports associated with physical cards

  The document speaks about 3 network cards that have been attributed to a vSwitch.

  The document then continue to talk about the creation of links to individual access to a network adapter for each VMkernel path.

  My question is:

  Why do this?

  Why not create three separate vSwitches and create an initiator iSCSI for each vSwitch?

  VCP3 & VCP4 32846

  VSP4

  VTSP4

  Why would you not create a vSwitch for each iSCSI NIC and VMkernel port. Why the document insists on putting all the NIC in a vSwitch?

  The number and type of vSwitches is not interesting.  You can use a vSwitch or vSwitches as much as you have physical NIC.  It works as well for the former two vSwitches static or vDS.  The configuration example is just one of the ways that you can do.  Any combination is supported.

• The s/w and h/w on the same host iSCSI initiators.

  Hello

  Can someone tell me if both software and hardware on the same host iSCSI initiators and looking the same LUN is supported in ESX3.5U5, 4.0U2 and 4.1.

  If this isn't the case, please give me the URL of any article of vmware goes in the same.

  Thank you

  P Martin

  The closest would be on page 28 of the 4.1 "iSCSI SAN slot Guide.

  http://www.VMware.com/PDF/vSphere4/R41/vsp_41_iscsi_san_cfg.PDF

  Because the software initiator ESX is definitely a charge adapter, this could be considered to be applicable.

  In spite of being is not clearly established, there is no summer tested enough to be considered as support even if there are no known issues.

• 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

  Post edited by: TonyJK

  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

• 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.

• 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.

• 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.

• How to display several software instruments?

  Formerly in Logic Pro X, I could see several instances of the GUI tools software and plugins. I have multiple monitors. Now, it shows only one at a time, and when I drag a GUI like Alchemy to a monitor and then click to display a GUI of the plugin effect it removes the first and replaces it. So I do not seem to be able to have more than one GUI open at the same time. Is there any solution for this?

  Do not know multiple configurations monitor, but on a single screen set up, it works very well.

  

• Multipathing with SW iSCSI initiators

  Hi all

  Just curious about the multiple and iSCSI paths. Summer hope to clarify a certain number of things.

  Taking an example of a single ESXi 4.0 host to connect to a device iSCSI via a network using a software initiator.

  
  A vSwitch was created on the host with two rising vmnic (two assets), which are connected to the storage network. A unique VMkernel port group was created on the vSwitch with an IP address on the storage network.

  Issues related to the:

  1 have I reason to think that the configuration above do not use the two vmnic for redundancy? I assume this is the case, because it shows only a single path under the storge device?

  2. assuming that the above is correct, that if I lost any vmnic is used, I'd lose access to my storage of this host?

  3. in order to provide redundancy in case of a failure vmnic, do I need to follow the steps in the configuration guide for iSCSI SAN? (http://www.vmware.com/pdf/vsphere4/r40/vsp_40_iscsi_san_cfg.pdf) That is to create two groups of ports on the vSwitch using vmnic active replacement (with the other unused) and use the CLI to create paths?

  4. If the default config is indeed only using a single VMnic, how can that be used?

  I think I already know the answer above but would like to have a validation...

  Thank you

  Chris.

  Tru Multipathing, your storage space must have at least 2 IP addresses.

  Do not confuse redundancy with multiple paths.

  While the two work together, you can have one without the other.

  To get full redundancy and multiple paths, at a minimum, your storage server needs at least two interface IP. you need to implement a vSwitch with 2 groups of VMKernel ports, as you mentioned below. #3 and port, then bind using the CLI.

  The political path roundrobin when value over (if your table is compatible).  You should then have 2 active channels.

  In your current config.

  # 1 there is redundancy, but no multipath

  # 2 No.

  #3-Oui - preferred method for many reasons with HA, path table and load balancing selection.

  #4-is not easy to find (at least not for me).  It really depends on how your political grouping vswitch is implemented.  Bad this refer to the experts.  Don't want to confuse.

• 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!
