• Can you point me to documentation or explain how to configure the iscsi hardware in vCenter?

  I have two HBA ports in two of my servers and a switch dedicated for iscsi. What are my next steps after that I get ready to go with my LUNS carved MSA20212i HP? What should I do with vCenter? I know I'm going in the storage area and search for new LUNS, Philippe isn't a step forward that?

  Hello.

  The best documentation to use will be Guide de Configuration of iSCSI SAN.

  Good luck!

• iSCSI hardware vs software adapter

  Hey all -

  I'm trying to figure out a vMotion (the issue being that it has essentially stopped working). A lot of what I read pins vMotion storage problems, so I start there. Anyway, while I was stung by storing a question occurred to me:

  If you have natachasery that can handle unloading iSCSI, iSCSI Software adapter should be disabled? that is, you should only use the adapter software if you do not have the ability to discharge with your physical network adapters, correct? Also, someone a hunch as to whether or not there was no disturbance, if I disable the software adapter (as far as LUNS are all showing on the HBA hardware)?

  Thank you

  It is a good question. I had the same setting up my storage. OK he think like this: If you have two ports on a 10 GB of a PS6010 controller, you technically "two" paths to an ESXi host, because each port has an IP address. You can see what path is related to IP in the section manage paths, in the target box (or below the paths section) say now you have two members, and both bear the same characteristics, you have now four active paths (e/s). It's really whatever the physical connection outside of the host. You might have a physical SFP + NIC and it would record two paths since you have two addresses targets, even if you have a "physical" path Kinda like a-< split="" if="" you="" want="" to="" think="" of="" it="" like="">

  All the below assumes that you have a dedicated set of switches, links dedicated to each Member and each switch with failover best practices in place. It is recommended that you isolate your network from your normal network storage. If you try to share the EQL storage with the normal operation of the network, you add an unwanted complexity.

  What you need to do is to make sure that your VMkernel iSCSI denomations are linked up to the the right vmnic. Under your EQL iSCSI vSwitch properties make sure you that you wanted to make a replacement of the switch for vmnic assignments (put the host in maintenance mode in order to test everything without killing any connection VM):

  • Click your vSwitch properties, select iSCSI0 and press 'change '.
  • Tab grouping of NIC, be sure that the order of failover is selected for "substitution vSwitch order of failover
    • Active adapters: vmnic 0
    • Unused cards: vmnic 1, vmnic 2
  • Follow these steps for the other two iSCSI designations, ensuring that you have only one per group of iSCSI ports.

  Something I noticed is that you don't have a group of dedicated port of vMotion. This should be done just for the sake of consistency, but does not mean that you must burn a port just for vMotion. In my environment, the port assignment looks like the attached screenshot (vSwitch assignments.png). Both of the vmnic are assigned to my group of ports of vMotion.

  Finally, make sure that MEM has linked the vmnic associated with iSCSI (above) to iSCSI Software adapter (vmhbaxx) traffic. You may want to just start over and delete the vSwitch, rerun installation MEM everywhere and then perform the steps above. But I need to show you what was going on until I told you to catch the vmnic and target the vmhba for the iSCSI Software initiator.

  At the end of this, you will have a configuration like this:

  • NIC teaming override for a vmnic for each port group.
  • All THE vmnic which is used for iSCSI communication RELATED to iSCSI Software adapter vmhba (i.e. vmhba36) using the 'config' MEM Setup Wizard
  • All the paths in your storage space must be Active (e/s)

  Does make sense? Joined a MEM so cheat sheet. It is based on the goal. I guess I call the sheet when I need to set it up in a hurry. You can see that Dell is too attached.

  Hope that helps.

• design for the iSCSI SAN review

  Hi all

  I intend to implement a storage shared in our vmware infrastructure. And we'll buy DELL or iSCSCI SAN NETAPP.

  Could someone pls review the design of SAN attached. Please note that we do not have a vCenter in the environment. And also we have not yet finalized on behalf of initiator SCSI, whether to use a software or iSCSI HBA for this purpose. Is it worth investing in the hardware initiator. Please suggest.

  Kind regards

  Nithin

  To use several vmks iSCSI, you cannot assign two network adapters to the iSCSI vmks.

  You cannot have an active nic by vmk and the other the vSwitch network adapter must be moved down to "unused controller. Then you can bind to port in the software iSCSI hba adapter. It is the only way to achieve real multichannel, load balancing and failover for multiple iSCSI vmks.

  Here's a KB on how do: http://kb.vmware.com/kb/2045040

  But if you google, it has quite a few tutorials with pictures detailed, etc..

• Optimal hardware recommendations

  Time for me to upgrade my laptop. I see the minimum hardware requirements, but if the main use of my new laptop will run Photoshop CS6 (and perhaps CC), what are the recommendations for a really good laptop (CPU processor, graphics processor, HD, RAM, etc.), not only the minimum?  I know that maybe it's not a particular brand laptop & model, but some tips on what is worth paying for, and what is beyond what Photoshop use anyway.  There may be a white paper of compiling recommendations out there?

• Differences between the ISCSI connections to the storage in vSphere 4.1 and 5.0.

  I'm in trouble of setting up the connections of storage in a new VSphere 5.0 test environment. In our environment VSphere 4.1, it was possible to create a virtual switch add two Broadcom NetXtreme II 5709 NIC. Set assets. IP Hash value as load balancing. (LACP Etherchannel on physical switches) This configuration uses a grain port and a single IP address. Then add our NetApp NFS storage and ISCSI Equillogic storage. In VSphere 5.0, I can't create this same configuration. I have to create separate with separate IP addresses vmkernal ports? The idea was to have redundant connections to the storage and flow of these two NETWORK cards. Possibly adding additional if necessary to the futuer NETWORK cards. Any help with this would be greatly appreciated.

  How can I work around this:

  "VMkernel network adapter must have an active link exactly and no waiting rising to be eligible for the iSCSI HBA connection."

  I can certainly say that the way which allows you to configure the iSCSI Multipathing is incorrect.

  The main idea is to let Native Multipathing Plugin to decide what network path to choose, not the vSwitch.

  At the level of the network layer, you must have 1 VMK by a physical NIC.

  This technique applies as well for vSphere 4.1 and 5.0, but with the 5.0 it is configured easier and more quickly.

  Here's a very brief consequence of steps

  1. get 2 VMK interfaces and assign an IP by each VMK.

  2. set each VMK to use only one physical NETWORK adapter

  3 GB with storage iSCSI software adapter, turn it on and bind your VMKs 2.

  4 connect to your iSCSI storage space

  5 rescan devices, create the VMFS datastore

  6. set the desired load balancing VMFS method or just set up a prior default create new VMFS

  and it is strongly recommended to read this guide - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-storage-guide.pdf

• An iSCSI hardware network card can be used for ordinary IP traffic?

  If I have a hardware iSCSI HBA card, it's a NIC where ESX could unload all iSCSI handling to, this card could be used for something other than iSCSI or it will only be dedicated to iSCSI traffic?

  In other words, for example, could vMotion or VM traffic more than NIC go too? (It obviously wouldn't be a good thing to do, but I'm curious to know if it is possible).

  If you mean an HBA full offload iSCSI, then the answer is no. The HBA actually operates all the management of the TCP/IP Protocol and presents the iSCSI LUNS to the host as direct-attached storage. If you go to the QLogic website, you can find a few whitepapers that explain unloading as well as certain patterns showing the CPU load with a THAT HBA full offload compared with active TOE NIC (such as HP/Broadcom).

• Left and initiator ISCSI hardware

  Hello

  I am wanting to install a Lefthand P4500 ISCSI SAN with 3 x ESXi4 servers and use hardware ISCSI initiator. Now, my question is I plug the adapter of material directly into the ISCSI storage or I can plug it into a switch that connects to the storage as with the ISCSI Software initiator?

  Thank you

  You can do both. I would use a switch (or more) to take advantage of multiple paths.

• We can connect the output of the sensor directly to the DAQ hardware or any interface necessary?

  We can connect the output of the sensor directly to the DAQ hardware or any interface necessary? If so wat kinda necessary interface?

  How to change the sensor output to match entry-level data acquisition?

  If the sensor output beyond daq range is provided. What are its effects? pls answer

  -It depends on your signal and the type of device you have. Your DAQ provides a package of signals? Also, what type of signal you want to measure? You must select DAQ that matches that. Take a look at the following before you start:

  Getting started with NO-DAQmx: Main Page

  And take a look at table 1 in the following article to wire your signal to the right:

  Wiring and considerations of noise for analog signals

  -You will need to use external circuitory to match the input of data acquisition range.

  -You could damage the unit.

  If you have any other questions, please after return. And, don't forget to give more details about your configuration, the hardware and what you're trying to do.

• What is the minimum hardware required to light a LED?

  Hello

  I want to have a few physical outputs very basic of my labview program, which can be summed up as "what is the minimum hardware necessary to light a lamp?

  The COM port can be used as a base i/o port, pins can be toggled?

  Some people seem to use Arduino to connect, how are easy to implement?

  And my last option I know is a dedicated i/o card. I guess that they are plug-and-play, but overkill for my purposes.

  See you soon,.

  You can easily use a COM port. There is a property node for control of handshake lines. Not sure that the com port is not TTL levels, not you? The voltage levels can be as large as +/-15.
