Shows poor drive on a virtual machine of SBS 2008 under ESXI 4.1

Hi all

I'll be back with a question on the locations of files vmdk and best practices.

With my colleague a great discussion raised about vmdk locations for a virtual machine that runs a heavy installation of SBS 2008. Where to place the files vmdk on the data store, and how to optimize for best performance.

This is the context. We recently bought a ML350 G6 server with 2 * RAID1 SAS 10 k. We have installed ESXI 4.1 on the first RAID1 array (datastore1) and the second RAID1 array, we created datastore2.

On the ESXI server, we have created a VM SBS2K8. And here is the discussion:

We have configured the vitual HDD for this virtual machine as follows:

DATASTORE1:

Next to the ESXI installation, we created 1 vmdk where we have installed OS by VM SBS2K8 partition

DATASTORE2:

We have created the 2nd vmdk where we have installed the DATA by VM SBS2K8 partition

For your information, directly after the installation we moved the log files and database Exchange on the second partition on DATASTORE2

Everything was nice during installation of the virtual machine, also during the installation of SBS 2008. The problems came just after the end of the import of the pst files in the Exchange database (+ / 20 GB for pst all together).

The virtual machine is so slow, when we try to copy, backup files locally. I checked the performance graph in VSphere Client when we copied the files or backup. The disk latency, data store, virtual disks to the level has exploded.

This is a point that the console has become completely insensitive during summits...

My opinion about it, is that it would be better to put 2 vmdk for virtual machine on DATASTORE2, but maybe I'm wrong. That's why I post here we are again.

All the recommendations, advice, are welcome. I don't know if the problem comes from the design of the virtual machine itself or we forgot something during the installation.

Is there a good literature on the vmdk files? Location, design...

Thank you for all your help on this point,

Michael

It sounds like you bought the DL350 G6 with P410i controller but no BBWC/FBWC not attached to the writeback operation. Without BBWC/FBWC, you will generally see less of ~ 10-20 MB/s.

Place the operating system partition and data on different data stores in this case makes no difference at all.

    In addition, if the option to increase the size of the disk in the VIC is grayed out, it sounds like a permissions issue.  Finally, you can not extend the disc using the VIC, if the customer in question has a snapshot.

  • Convert a hard drive to a virtual machine

    I have a server that the material died which has mirrored hard SATA hard drives in them.  I would like to convert the data on that hard drive to a virtual machine and put it in my vCenter, but I am unable to start the server.  What is the best way to do it?  I can mount and read data from Windows on another machine.  Right now I'm trying to back up data until an acronis image and then use converter to import.  I think it is easier to sense, though.   I also have a backup server Symantec Backup Exec, but I do not have the agent ESX for Symantec.

    Thank you

    Dave

    If you want to try the converter, just fix the disk on a physical host somewhere and run a normal conversion.

    Once you have done this, create a new empty virtual machine with no disc and you fix vmdk for the reader you want migrated to this new virtual machine. Chances are that you will get the normal NT Loader boot error when you try to start, but you should be able to solve this problem using a fo the following:

    DiskPart

    Fdisk

    Recovery Boot

    You can also consider to use something else than VMware converter - perhaps something like Acronis True image?

    Good luck and please feed back.

  • Partitions of hard drive on a virtual machine

    Hello

    I have a few questions related to the hard drive on a virtual machine.

    1. is it possible to create multiple hard drive partitions (virtual hard disk, we can add, modify the virtual machine settings) that we have in our PC? In the case the ESX Server and Workstation?

    2. in WMware Workstation by clicking on change settings for virtual machine, I've added an extra IDE drive and allocated 1 GB of space, so now I have two hard drives. I said my virtual machine (Windows XP is the guest operating system), I expected to see the additional drive as "D:", but it was not! What stage is omitted by me?

    Thanks to AdvanceSalahuddin

    1. Yes.  Treat your virtual machine exactly as you would with a physical.

    2. yet once, as you would in a physical installation.  When you add a hard drive, you must go in disk management, select the new drive, create a partition on it and format the partition.

    Yes - you can
    but that will make your VM very slow

    set
    prefvmx.minVmMemPct = "50".

    or less - allowing you to approve the RAM
    Set this parameter in your config.ini file

  • Need help with replacing a drive on a virtual machine

    Test case for something I need to do on a separate production machine.  Virtual MACHINE is running WinSvr2003.  Only the hard disk assigned to the virtual machine is one of 20 GB disk, C: using this.  Need to C: to be larger.  Add a 40 GB drive to the configuration of the VM in the CR.  Started an iso BartPE with plug-in in Ghost.  Ghost can copy the C: 20 GB drive on the 40 GB drive.  Went in the VM config and changed is the 40 GB SCSI 0.1 drive and the drive of 20 GB at SCSI0, 2.  After I saved, VMware changed the 40 GB on disk 1 and the 20 GB on disk 2.  Went it into the BIOS on the machine config to boot the disk of 40 GB.  But no matter how I put it in the BIOS, it would only start on the 20 GB drive.  Went in the VM config and removed the 20 GB drive (which is not an option on the production machine, it has a volume of data on the same drive).  It boots to Windows, so I guess it's start on the 40 GB drive.  But I am unable to connect to it.  It shows that the application of settings, record the settings, then back to the login screen, all within 2 seconds approximately.

    Is there anything else I need to do to (1) move the volume from the Windows system to a new disk w without side effects in Windows and (2) so that it can start on the new disk correctly?

    If it is a single virtual drive with 2 partitions and the C:\ is on the front of the drive, Extpart won't help. It is usually best to separate the partitions to multiple virtual disks. I use the converter to V2V the VM and move on their own virtual disk partitions, then develop them if necessary.

  • Sharing the drive between several virtual machines

    Hi all

    We have a configuration with a SAN (Dell Compellent) and use vSphere 6 to host a number of Windows servers. We now have a giant machine of Windows with a large number of small files for a particular application.

    Now, we would like to create a cluster with a LoadBalancer in front of him, so that we can handle more load. To do this, we want to create a disk that is shared between 2 (or more) of windows machines.

    One of the problems is that NTFS is not a supported clustered file system. So, I did a lot of research on Google to see what my options are. In my opinion, they are the following:

    1. set up a Cluster Shared Volume (CSV) Microsoft (use SMB if I read the documentation)

    2. the user Windows shares on a separate file server

    3. the user NFS (depreacted under Windows)

    4. switch to Linux and use NFS

    The problem I have, is that they use all the network traffic. For example, option 2 is ridiculous slow. NFS under Linux is also a way slower than the local drive (managed by VMWare iSCSI) disk access and NFS on windows does not appear to be

    support very well.

    I know that there are aware filesystems, clustered as VMFS etc. Is there a way to access it directly from my Windows VM or are there devices SAN which is directly accessible from the virtual Windows machine?

    Or maybe there are other solutions to set up a shared drive?

    I know that there are aware filesystems, clustered as VMFS etc. Is there a way to access it directly from my Windows VM or are there devices SAN which is directly accessible from the virtual Windows machine?

    VMFS is a really clustered file system and allow access of multiple virtual machine the same amount of storage (data store) which is different from that to create a virtual disk (hard) and present to multiple virtual machines. You can do this, BUT the guest virtual machine should take care of several accesses to the hard, for Windows, you must turn on the feature... without this clustering with failover data may be corrupted.

    I think the best and supported solution for you is to create another cluster with Failover Cluster functionality and create a resource sharing files with files that will access your NLB nodes.

    Thank you



    You basically configure the virtual machine that you want on all the available storage (do not forget to keep free space, for example snapshots). -As I understand it - is so that ESXi does not see the storage! This is often caused by the RAID controllers not taken in charge or the RAID issues. Please check if the RAID controller is supported as well as the configuration. BTW. Why do you want to configure RAID0? If you want to create two virtual disks on warehouses of separate data anyway, simply present to ESXI as two separate disks/volumes.

  • VCenter shows a network for a virtual machine that is not associated with any host

    I have a win2k3 VM who at one point had a network assigned to him called "MONITORING".  This network is configured is no longer in the ESXi (5.5) environment.  The virtual machine is connected to a network called "PRD-SURVEILLANCE" which is correct.  It's not really cause a problem, but I can't find a way to get rid of the object of MONITORING network.

    In VCenter MONITORING networks has a VM of 1 meter, the number of hosts of 0.  I also see it in the VM - dialog box, change the settings, but there is no option to remove it.  Profile Image to the virtual machine is version 10 so I can't use the old Client of VI to try to remove it.  I have checked each host and do not see this listed network object.

    I tried to restart the VM, it migration between hosts, changing its network of SURVEILLANCE of PRD to another network and vice versa and close - remove NIC and add a new card network.  MONITORING legacy network still appears in the config.

    For the virtual machine's .vmx file shows that the correct network: ethernet0.networkName = 'RDP-ANALYSIS '.

    Any suggestions on how I can remove the artifact of MONITORING network?

    The virtual machine has a preview that was created at the time where the MONITORING network was still affected?

  • Support ESXi 5.0 host FC connected tape drives in the virtual machine running symantec backup exec 2012

    Dear Experts,

    We recently purchased C0H19A: StoreEver HP 1/8 G2 6 - LTO Ultrium 6250 CF TapeAutoloader. The purpose is to backup of VMS data, I mean selected data in virtual machines, as for the exchange of data bases email for server accounts database SQL server etc.. We have a full VM backup plan, so using symantec backup exec software.

    We have this configuration:

    -TWO DL 380 Gen8 servers (running UPDATE2 Esxi 5.0), both servers have not all SCSI ports

    -One SINGLE HP P2000 G2 MSA FC Dual Cntrl storage

    -TWO HP SN6000 12 - pt Windows Pwr FC switch

    -HP ADF

    All them above are related to the CF. Symantec backup exec 2012 is also installed on Windows 2008 R2, which is a virtual machine.

    But now, we are unable to see the tape library autoloader through the virtualization layer in the device of machine Manager virtual backup exec. Reading on internet, I also found some details that connected FC tape drives are not supported by the Esxi hosts. We are really stuck in this situation, all the solutions to this. I also read the article from vmware saying configuration for Esxi 4.0 FC tape drives and later versions

    Installation of a physical server windows with Backup Exec 2012 and HBA and connected to above switches FC is the only way to see the ADF? Even after reading articles on the internet, I'm not clear, please guide what solution I have now to get this thing going, I really need to find solution to this.

    Waiting for answers.

    Kind regards

    Hello, I'm a Backup Exec support engineer and yes the method supported is only by connecting the tape drive to a server of physical media.

  • Adding a new drive on a Virtual Machine

    Hello

    I need to add a new disk to a virtual machine that runs as an Exchange Server.   Normally, when you add the new drive I would choose the store with the Virtiual Machine.  Unfortunetrly the Datasotre stored on the virtual machine is virtually complete.  What are the implications of the selection 'Specify a location' during the creation of the disc.  I'll always be able to use VMotion?  and how the disk get stored on the selected locvation.  He appears as a vmdk file in a folder named after the Virtual Machine?  Anything else I should look for?

    Thanks for any advice.

    Concerning

    Kevan

    You mentioned already correctly more points:

    • the vmdk will be stored in a folder with the name of the virtual machine
    • vMotion is not affected until all guests have access to the data store
    • According to the snapshots the ESXi version are either created in the home folder of the virtual machine (before 5 ESXi) or in the folder parent of vmdk

    Hello

    No you can't change it.

    A single operating system can directly access a system of files at a time unless it is a clustered file system.

    Like any normal filesystems like NTFS/FAT/etc... are clustered, you cannot do so.

    The answer to that is to share your files via network shares.
