How data travels in the iSCSI Configuration

Hello

I'm a little confused about how DATA moves through an environment of VI3.5 using iSCSI SAN.

Before, I am attaching a schema, so everyone will be on the same page.

It is a scenario with two servers ESX (ESX1 and ESX2), a physical server (Server1) and 4 Virtual Machines. (VM1 ~ 4)

vmnic0 is for traffic Service console and the virtual machine.

vmnic1 is for vmotion, but on the same subnet that are Virtual Machines.

vmnic2 and 3 are for iSCSI and Service console for iscsi on a different subnet and different switch.

The example is for the understanding of the performance and the communication network and not for security reasons.

I know that when you want to use VMotion and HA, you need to use Shared Storage (IE iSCSI SAN) and your virtual machines are stored on the SAN.

Here are my questions:

1 - is this correct design?

2-if I want to copy a VM1 VM2 to file, how data moves? (knowing that both are stored on the same SAN and they are both on the same ESX Server)

3-if I want to copy a file from VM1 to VM3, how data moves? (Knowing that both are stored on the same SAN but they are on different ESX servers)

4-if I want to copy a file to the server Server1 to VM1, how data moves?

5 - If you do a VMotion VM1 from ESX1 ESX 2, how data travel? (I know for VMotion the contents of the RAM to the virtual computer will be copied to the second serve of ESX) This will affect the performance of the local network?

6. What do you recommend to monitor traffic on vmnic?

Please include the question number in your response.

Thank you

1 - is this correct design?

OK for iSCSI.

But you do not HA hat on the breakdown of the network cable or the NETWORK card (for the first 2 vswitches).

It is good to have iSCSI separated by VM and VMotion, but usual for each vSwitch to give at least 2 cards of uplink.

You can for example put VMotion and VM on vswitch, using 2 NICs and affecting a NIC preferred for the virtual machine and a preferred (different) for VMotion NETWORK card.

2-if I want to copy a VM1 VM2 to file, how data moves? (knowing that both are stored on the same SAN and they are both on the same ESX Server)

VM1 and VM2 could talk via the network of the VM.

So VM1 get data from the vmknic2/3 (if is not in the cache of the comments), copy to network (vmknic0), VM and then store the data (and goes to vmknic2/3)

3-if I want to copy a file from VM1 to VM3, how data moves? (Knowing that both are stored on the same SAN but they are on different ESX servers)

Same as before, using 2 ESXs

4-if I want to copy a file to the server Server1 to VM1, how data moves?

vmknic0, then vmknic2/3

5 - If you do a VMotion VM1 from ESX1 ESX 2, how data travel? (I know for VMotion the contents of the RAM to the virtual computer will be copied to the second serve of ESX) This will affect the performance of the local network?

vmknic1

6. What do you recommend to monitor traffic on vmnic?

You can use the tab Performance on ESX.

  • How can I delete the previous configuration of Essbase Server Shared Services?

    Hi all

    I am trying to reinstall the Essbase Server (on a new server we have upgraded the Essbase server hardware) and reloads the data, but the current installation believes that I have already set up despite the withdrawal EssbaseCluster-1 of Shared Services Application groups.  Is there something else I need to do to get the new install Essbase server configured as a new instance of Essbase?

    Thank you
    Ryan

    If the server names have been changed, then it probably won't work, but I don't know what you mean that it did not work, you should check the registry of shared services, other possibilities are reset configuration tasks in the registry by using the epmsys_registry utility.

    See you soon

  • How to increase the size of the iSCSI data store?

    I try to add an iomega StorCenter as an iSCSI target.  I added the storage card which indicates the total capacity of 8,13 TB in vSphere Client (it looks like the right size).  Now when I add the data store, however, is that there only 128,75 GB of capacity (this is where the problem).  How can I recover the full space available?  It's almost as if I need to increase size of partition or something, but I don't know how to do this.

    Also, if I click on the data store > properties, the increase... button opens a dialog box, but there is nothing for me to choose.

    System / / desc:

    ESXi 4.0

    (This does not have room for the VDR backups)

    Welcome to the community - ESX 4 only supports storage of 2 TB - 512 B data - you will need to carve up the storage being presented in LUNS which are smaller than 2 TB - 512b

  • How to save data quickly to the high sampling frequency

    Hi all

    I use a structure of producers and customers to measure and record the data. The sampling rate must be as high as 10 kHz. Given that so much data, it takes a long time before the data is saved. At first, I saved the data in an excel sheet. Then I tried to save it in binary, but it still takes a while to complete save. How can I make the time savings a short circuit?

    Thank you

    The best

    First we will make some corrections to your DAQmx code.  Since you are using continuous sampling, do NOT connect the samples per channel.  Which is actually limiting your buffer.  And there is really no need to define your buffer size either.  It is default to very big, so this isn't a problem as long as you read your data quite often.

    Now your data connection... You simply create a very wide range while acquiring data.  Then, you save the data.  It's actually not through the advantage of using the producer and the consumer.  You should save your data in the loop of the consumer.  It will be elinate need a lot of memory and you save the data to the file while you are buying.

    But, in this case, I say that the producer and the consumer is not even necessary.  Use the DAQmx Configure registration VI.  With this VI, you can tell DAQmx to disseminate all data directly in a PDM file.  You don't have to do anything.  It is by far the best way to save on your DAQ data.

  • How can I get the data from a range of AutoFilter in Excel?

    I have a spreadsheet with a large number of lines (5000) where I want to extract data.  I have opened the workbook successfully, configure an automatic filter and filtered the data to select the data corresponding to the criteria using the nodes property of the ActiveX Excel object and invoke.  I now have to enter the selected data in a table for later processing, and this is where I am stuck.  Help Excel online seems to suggest the creation of a Range object by using special cells with the xlCellTypeVisible type.  If I Range.Count I get the right number of cells, but Range.Value2 produces a variant which contains only the first block of data (a beach filtered automatically seems to consist of several non continuous blocks).  Anyone know how I can read the contents of the range in an array of strings?

    Thanks in advance

    Ken

    IT SOLVED!

    Found a calling areas of property which returns a collection of the areas of each of them continues a range object.  Simply cycled through these areas using the earlier technique, build the table I want.  See below

  • How do you use the freqout as the sample clock to write data on the of 6224 PCI

    Using PCI-6224, I try currently to export data using the freqout as a reference clock sample to a digital output channel. I plug the scope to see the clock on the freqout PIN. However, the data seem to be missing. How can I output the data correctly using the reference for timing? What am I missing that connects the two signals together? Any help would be greatly appreciated. I am writing this code in MS VS C++ and here's what I've done so far:

            int32       error=0;
            TaskHandle  taskHandle=0;
            TaskHandle  taskHandleFRQ=0;
            char        errBuff[2048]={'\0'};
        uInt8       data[8]={1,0,1,1,1,0,1,0};
    
        /*********************************************/
        // DAQmx Configure Clock
        /*********************************************/
        DAQmxErrChk (DAQmxCreateTask("",&taskHandleFRQ));
        DAQmxErrChk (DAQmxCreateCOPulseChanFreq(taskHandleFRQ,"Dev2/freqout","",DAQmx_Val_Hz/*Units*/,DAQmx_Val_Low/*IdleState*/,0/*Delay*/,10000/*Freq*/,0.5/*DutyCycle*/));
        DAQmxErrChk (DAQmxCfgImplicitTiming(taskHandleFRQ,DAQmx_Val_ContSamps,8));
    
        /*********************************************/
        // DAQmx Configure Digital Output
        /*********************************************/
        DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
        DAQmxErrChk (DAQmxCreateDOChan(taskHandle,"Dev2/port0/line0","",DAQmx_Val_ChanPerLine));
        DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"/Dev2/PFI14",10000,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,8));
    
        /*********************************************/
        // DAQmx Write Code
        /*********************************************/
        DAQmxErrChk (DAQmxWriteDigitalLines(taskHandle,8,0,10.0,DAQmx_Val_GroupByChannel,data,NULL,NULL));
    
        /*********************************************/
        // DAQmx Start Code
        /*********************************************/
        DAQmxErrChk (DAQmxStartTask(taskHandleFRQ));
        DAQmxErrChk (DAQmxStartTask(taskHandle));
    

    I think that the original code was operational. However, given that the data transmission has been set to finished, I had a hard time to visualize the data on my scope. By changing the value of DAQmx_Val_FiniteSamps to DAQmx_Val_ContSamps, I could easily see the data.

    My mistake. I'm still learning here. Thanks for the time.
