Separate the VMkernel for pulse data store traffic?

Hello.

I was just reading Tech EqualLogic report 'Configuring iSCSI connectivity with VMware vSphere 5 and Dell EqualLogic PS Series storage' and saw something again on pages 3-4.

Dell recommends to create a vmkernel port highly available on the subnet iSCSI serving as vmkernel default port for pulse data store traffic, so that the pulsation of data store traffic will then sit outside the iSCSI Software initiator and consumes any connection of additional iSCSI storage. He goes on to say that the traffic of pulsation of the data store will always use the lowest numbered VMkernel ports on the vSwitch.

It makes sense, but this is the first I've heard of this. Everybody does that, with EQ or other iSCSI solutions?

Thank you

Brian


Not sure that what talking about Dell, but the heartbeat "traffic" data store using the links normal iSCSI. Each host will have a file on one of the heartbeat data stores and open it which means there a lock on the file. The overhead is minimal and there is no need to worry at all.

  • Get the scsi for a data store information if the data store is known

    Hello

    I'm looking for a way to get the information of scsci for a data store if the name of the data store is known. In perl/powershell, this is not a big problem, but how to do this using the Orchestrator. It seems that some information is not available/accessible in vCO, as information volume.extent (object VcHostFileSystemVolume).

  • How to change the vmdk in another data store

    for my vm four disks are there I want to increase disk capacity but there is no space on the data store

    Hello

    Solution is that you must change the drive to another data store and increase space.

    First findout in spatial data store is avaialble.

    Select the virtual machine and migration - migration datastore - Advanced - click the drive on which you want to increase space - browse - choose data store where space is available - finishing

  • Conversion in failure "the reconfiguration of processing data store.

    I'm trying to convert a Windows XP SP3 machine that has one partition D:. When I try to convert, it fails to stage "Transformation of the reconfiguration data store" with an error indicating "FAILURE: unable to find the system volume, reconfiguration is not possible." I checked the boot.ini file and it seems to be ok, however when I run a Spotmau CD to try to make some recovery/survey to see what the problem is, it shows Windows is on C:, and in the conversion process step that says "Drive to update for the layout of the destination volume letters" goes and comes without error , so I guess that converter is changing the drive letter, that is all pipe up. Can I prevent converter to change the drive letter, or can I change afterwards?

  • Moving a disk of the user in another data store

    Hello!

    I have an office pool that is used by a few users and now I discovered, as i wan't to upgrade the user drives my Netapp file server to use snapshots on them. Is there a way to move a disc of the user to its current location on the same os drive data store was a new data store?

    I know that I can put in place a new pool, but let the user discs when I do this, so this isn't an option.

    Anyone know how I can keep my user records, moving them to another data store?

    Currently a UDD cannot be moved the data to be backed up and restored. Alternatively, you can also turn on roaming profiles have the connection of the user in two places, once everything is in place, turn them off.

  • Nobody knows the largest available space supported for vmfs data store when creating a new form of vmfs data store a 3T lun mapped from FC storage.

    I traced a form of lun 3 t FC storage.

    And the project to create a vmfs on this lun, creating, data store, space available by default is 1024 G, no 3 t, so I guess that maybe some limitations.

    Anyone know? Thank you very much.

    Hello

    The limit is 2 TB - 512Bytes

    That 512 bytes is VERY important to remember.

    You will see that 1 TB as it roles once you exceed 2 tablespoons.

    As Anton suggested you can use two 1.5 TB LUN safely. However, you can in fact more than 500 GB LUNS or such. Will the LARGEST you can is not always the most efficient allocation of resources.

  • How do I cancel the mapping of a data store of esxi host without data loss

    Dear team,

    I want to cancel a data store that is mapped on two cluster mapping (cluster1 10 esxi host and cluster2 esxi 4 guests)



    Query1

    What step will be OK

    Disassemble = > detach = > start the activity of storage (storage poweroff) movement = > move the storage = > poweron = > join = > mounting

    or

    Disassemble = > detach = > team san will cancel the mapping = > start the activity of storage (storage poweroff) movement = > move the storage = > poweron = > san team will map the data store = > join = > mount

    Query2:

    Once I sail, I am able to see vpshere ha and dvs folder data, I just want to confirm if I want to take it apart and to separate the data store it will allow me to do it or it will throw an error, please confirm.

    Query3:

    If we remove and detach a data store, before that I have to cancel the registration of all the virtual machines?



    concerning

  • Storage VMotion for several data stores

    I'm looking for some advice and assistance with the help of the vSphere PowerCLI to SVMotions.

    I found that I can use virtual vmname Get-machine | Move-VM - datastore (Get-Datastore datastorename) that has worked very well and I was ready to roll. However, it occurred to me that I can only refer to a data store in the cmdlet and some of our virtual machines have their drives located on different data warehouses.

    So I set up a test VM with two disks of different data warehouses and began a SVMotion. The result was that it has migrated all disks in their separate data warehouses in a single folder on the target.

    What I need to be able to do is to migrate a disk and leave the other in its original location, or migrate two disks of different locations in two different places again. As you can do if you switch the machine virtual and migrate through the graphical interface, moving storage with advanced options (and probably what you can do via the graphical interface with the virtual machine in vSphere).

    I've got ESX 3.5 Update 5 with vCenter 2.5 update 6 If no GUI in VirtualCenter and the free snap option not taken in charge is not an option.

    Is there a way to do it with the PowerCLI or am I limited to migration the data store's unique virtual machine?

    Thank you very much.

    This can be achieved using the. RelocateVM_Task() method of the VirtualMachine SDK object

    See the code below:

    $configDatastoreName = "DataStore_01"
    $HardDisk1DatastoreName = "DataStore_02"
    $HardDisk2DatastoreName = "Datastore_03"
    
    $vm = Get-VM VM001
    
    $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec
    #Get MoRef for Destination datastore for Config files
    $spec.Datastore = (Get-Datastore $configDatastoreName | Get-View).MoRef
    
    #for each disk specify where the vmdk files should be placed.
    #If a vmdk should NOT be moved, enter its CURRENT datastore
    #If you forget to specify a disks location, it will be moved to the datastore
    #specified in $spec.Datastore
    
    #HardDisk 1
    $objDisk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator
    $objDisk.DiskID = $vm.HardDisks[0].Id.Split('/')[1]
    $objDisk.DataStore = (Get-Datastore $HardDisk1DatastoreName | Get-View).MoRef
    $spec.Disk += $objDisk
    
    #HardDisk 2
    $objDisk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator
    $objDisk.DiskID = $vm.HardDisks[1].Id.Split('/')[1]
    $objDisk.DataStore = (Get-Datastore $HardDisk2DatastoreName | Get-View).MoRef
    $spec.Disk += $objDisk
    
    #When all harddisks are specified call the RelocateVM_task()
    $vm.ExtensionData.RelocateVM_Task($spec, "defaultPriority")

  • ESXi connection to the Windows SFU NFS data store

    We plan to install 3 servers ESXi with virtual machines hosted on local.  A backup script align the images and move the *.vmx and *.vmdk to a NFS data store located in separate facilities which are connected via fiber.  All connections are links of 1 G.  The NFS data store will be hosted on w2k3 with SFU (Microsoft Services for Unix).

    The NFS data store will be a target for cloning and will be located in a building separated for "geographical separation."  I tested with Veema FastSCP (the public beta)... it's ok (30Mbytes/sec).  I assume that the clone process will take about 5 hours - but we can tolerate the performance hit after opening hours.

    Question:  Is there a "traps" to know by linking each ESXi server in the same directory NFS exported using SFU?  Perhaps more to the point... no problem with ESXi and Windows SFU?

    Before anyone asks... we do this on a 'super-thin budget' (that is to say... $ 0) using existing hardware, otherwise I would have ESX Enterprise and SAN storage!

    Some discussions to look at on the performance.
