ESXi with two data warehouses

• If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  The reason why I ask, is that I have two hosts ESXi ESXi 4 running.  I do my backups with ghettoVCB, which I modified to create thin backups on one of the drives the.  I then wput them to the server, which causes them to become thick.  Directly targets the backup in a vmfs iSCSI on the server in the face shop.  It would save a step and the vmdk backup should remain thin.

  Thank you!

  The short answer is Yes. If you allow the ESX servers to see the LUN. This setting is configured to the Openfiler.

• I have a virtual machine that is resident on two data warehouses, and I need to move

  Okay, I'm trying to reconfigure the storage on a cluster of ESXi to software development, and I fell on a virtual machine that is resident on two data warehouses.  Somehow, the user has configured this thing to have most of the VM files on the data store 5 while all the vmdk but the residence on the data store 1 boot drive.  He probably did it because of the size of the old warehouses of data and the many VMs older than his colleagues left sitting.  Well, now I just reconfigure data warehouses so that there is more usable space, but I can't move this machine a virtual so that I can reconfigure the rest of storage.  (For reference, the old warehouses of data have been implemented in 4 sets of three disks in RAID 3 and a set of four disks in RAID 3 with two drives hot spare.)  For the record: not my idea.  I am reconfiguring them now to be a set of 15 drives in RAID 6, divided into two LUNS on both controllers, with a hot spare.)

  Well, now I need to figure out how to get this VM is spent at one of new data stores.  The data migration store feature does not work.  Any recommendations?

  Hi Dangingerich,

  You can move the VMDK individually with the advanced functionality of storage vMotion allows you to ask the data disk on your new storage space and then have the OS disk track.

  When you svMotioning click on the Advanced button

  

  Here you can select the individual VMDK and move.

• [SRM 4.1] Dealing with local data warehouses?

  Hello

  I'm currently loaded with SRM 4.1 installation on our companys vsphere and while I did this before that I have never worked with VM on local data warehouses. There are three additional centers for both, I'll be tipping. These three data centers all run on Cisco UCS 210 M2 servers spread across two data stores. The virtual machine can be found on the second partition of the UCS VMFS.

  I don't know why it was created this way that I wasn't there when it was put into service (it seems strange, though, as they have a shedload of space on the Symmetrix). So I ask really (a person with a more experienced eye), what are the options for local data warehouses with MRS? I'm guessing limited to no support... so think I might watch svMotion

  Thanks for any advice.

  Hello

  With MRS. 4.1, the only option is based on the Bay of replication, i.e. SRM is only able to protect virtual machines residing on storage arrays supported with replication configured between them. SRM itself does not perform the replication. SRM is able to display your replica equipment and perform a few operations on the Bay of storage through the SRA (storage replication adapter) - software written by the storage provider.

  Yes, unless you use a storage device which can present these local data warehouses such as those shared and replicate them on the (and is supported with SRM), you cannot use local data warehouses. I have a limited knowledge of such things, maybe the other guys will be able to help more.

  In SRM 5 extra option has been introduced - vSphere replication, which allows the replication of virtual machines between ESXi hosts. You will need vcenter / SRM and ESXi 5 for this to work.

  I do not understand your configuration. How many centres of data do you have? SRM only supports the scenarios one to one, and many-to-one.

• Maps JSON data with two data in the list

  Hey all,.

  Been working with JSON data and informing the lists for a some time now, but im stuck now on a single set of data.

  The data structure is the following:

  [
       {
            data: {
                 children: [ {
                      {}
                      {}
                      {}
                 } ]
             }
       }
  
       {
            data: {
                 children: [ {
                      {}
                      {}
                      {}
                 } ]
             }
       }
  ]
  

  The data that I take care of normally contains one of these structures and not 2 as in the above data. So what follows could could work:

                                  const QByteArray response(reply->readAll());
          ArrayDataModel *model = new ArrayDataModel();
  
          bb::data::JsonDataAccess jda;
          QVariantMap results = jda.loadFromBuffer(response).toMap();
          QVariantList children = results["data"].toMap()["children"].toList();
  
          model->append(children);
          mListView->setDataModel(model);
  

  However, it is now giving me an empty list. So how can I limit the above code to analyze and insert only the 2nd set of JSON data in the list?

  Please let me know if it needs to be clarified. Any help is appreciated. Thank you!

  Hello

  It contains a list of maps. Have you tried something like the following:

  bb::data::JsonDataAccess jda;
  QVariantList results = jda.loadFromBuffer(response).toList();if (results.size() >= 2){
      QVariantMap secondSet = results.at(1).toMap(); // to get the second map
      QVariantList children = secondSet["data"].toMap()["children"].toList();
      model->append(children);}
  

• Move all files with the file hard, in two data warehouses

  You can move these files from the data through VC or WinSCP3 store? You have on the eve of vm? There is that one disc and files are on two separate data stores.

  Please move configuration files to the same data as the vmdk files store to ensure an appropriate server recovery. I ran a backup because it is now, but in this State, I can't assure you that I will be able to recover properly. ProdVMLUN1A3/CO01 (configuration files) ProdVMLUN4A22/CO01 (vmdk files)

  If you're on ESX 3.0, you can do a few things.  We could be to stop the virtual machine in question, and then choose migrate.  In the wizard you will be asked if you want to 'keep' or 'move', choose move.  Another way would be to use VMware Converter

  If you ran 2.5 and ESX 3.5 vCenter, you could do it live with sVmotion.

• How to use SMotion to move a virtual machine on two data warehouses

  
  Hello, I have a virtual machine that has two VD (VD1 and VD2) and they are on different data (DS1 and DS2) warehouses.  The OS is on VD1 and VD1 on DS1.  Data on VD2 and VD2 is on DS2.

  Is it possible to use SMotion to pass just VD1 of DS1 to anthers datastore (DS3) but leave VD2 on DS2?

  I tried to move, but I don't see an option to move just a VD.

  Any help will be appreciated, thanks in advance.

  I found the ADVANCED button on the section of storage of the migration wizard, see the screenshot below.  It allows you to individually select your locations of migration.

  Hope this helps someone.

  

• Restore directly to a host ESXi with VMware Data Protection (WTP)

  Can I use VMware Data Protection restore directly to a host ESXi, or do I have to have vCenter Server running? (If the virtual machine, I am trying to restore is vCenter Server itself, then it won't work unless I can restore to a host ESXi directly without using vCenter Server...)

  You don't need a vCenter running for the restoration of emergency (directly to the host).

  You can also use this direct restore to restore a vCenter to a host. I think this is the main reason that this feature was developed

  Edit: More on it in vSphere Direct-to-Host Data Protection's emergency recovery. VMware vSphere Blog - VMware Blogs

• Keep two very large synchronized data warehouses

  I look at the options to keep a very large (potentially 400GO) datastore TimesTen (11.2.2.5) in sync between a Production Server and [sleep].

  The replication was abandoned because it does not support compressed tables, or table types creates our closed code (without PKs not null) application

  1. I did some tests with smaller data warehouses for the indicative figures, and a store of 7.4 GB data (according to dssize) has resulted in a set of 35 GB of backup (using ttBackup - type fileIncrOrFull). This surge in volume should, and would it extrapolate to a 400 GB data store (2 TB backup set?)?
  2. I have seen that there are incremental backups, but to keep our watch as hot, we will restore these backups and what I had read and tested only a ttDestroy/ttRestore is possible, that is full restoration of the full DSN every time, which takes time. Am I missing a smarter way to do this?
  3. Y at - it other than our request to keep two data warehouses in the construction phase, all other tricks we can use to effectively keep the two synchronized data stores?
  4. Random last question - I see "datastore" and "database" (and to a certain extent, "DSN") apparently interchangeable - are they the same thing in TimesTen?

  Update: the 35 GB compress down with 7za to slightly more than 2.2 GB, but takes 5.5 hours to do this. If I take a fileFull stand-alone, it is only 7.4 GB on the disc and ends faster too.

  Thank you

  Post edited by: rmoff - add additional details

  It must be a system of Exalytics, right? I ask this question because compressed tables are not allowed for use outside of a system of Exalytics...

  As you note, currently the replication is not possible in an Exalytics environment, but that is likely to change in the future and then he will certainly be the preferred mechanism for this. There is not really of another viable way to proceed otherwise than through the application.

  With regard to your questions:

  1. a backup consists mainly of file of the most recent checkpoint, more all the files/folders that are newer than this file logs. Thus, to reduce the size of a backup complete ensure

  that a checkpoint occurs (e.g. "call ttCkpt" a ttIsql session) just before starting the backup.

  2. No, only the restore is possible from an incremental backup set. Also note that due to the large amount of rollforward needed, restore a large incremental backup set can take quite a long time. Backup and restore are not really intended for this purpose.

  3. If you are unable to use replication, then a sort of application-level synchronization is your only option.

  4 data store and data mean the same thing - a physical TimesTen database. We prefer the database of the expression of our days; data store is a legacy term. A DSN is something different (Data Source Name) and should not be swapped with the data/database store. A DSN is a logical entity that defines the attributes of a database and how to connect. It is not the same as a database.

• Storage vmotion, between data warehouses when the block size is different

  Hi all

  I would like to know, is it possible to do a vmotion of storage between two data warehouses, when they have different block sizes. The case is as a former vmfs data store 3 which has been upgraded direct to vmfs5 there, but since it has been updated it maintains its own block size. While the newly created vmfs datastore 5 a block size of 1 MB.

  Thus, storage Vmotion will work in this case? It will fail OR will be with degraded performance?

  Finally, storage vmotion is possible even if you do not have a cluster DRS for storage?

  Thank you

  Yes you can!

• ESXI stores its data outside the partition files?

  HI guys just a question for the gurus of VMware.

  The data store and vmdk files are stored on a different partition or the part of the hard drive for the operating system to esxi.

  We know.

  concerning

  Neo

  The files that make up a computer virtual, including VMDK are stored in a VMFS data store and if I remember with the default install ESXi a partition is created and formatted as a VMFS data store but you can have shared storage (SAN or NAS) that can also be configured with VMFS data warehouses and store virtual machines , including the VMDK files it

• Upgrade question for data warehouses - want a confirmation

  I have read in the upgrade guide and think I have the answer, but would like a confirmation e-mail.

  It's my current scenario:

  Three ESX 3.5 update 3 guests share a single fibre channel LUN and two iSCSI LUNS. The LUNS are all VMFS3 format.

  vCenter 4.0. (It was just upgraded from 2.5 to 4.0 today)

  I would add a fourth server from vSphere ESX 4.0 in the data center. I would like for this server to be able to share the same LUN VMFS3 as other ESX 3.5 hosts. Then I will move the VM from 3.5 servers to the servers of 4.0 one at a time, the upgrade of the VMTools on the virtual machine I. When I get enough VM on one of the servers of 3.5, I can pass this host to 4.0, and then keep the VM off the coast of 3.5 moving slowly until they are all on 4.0 hosts and guests 3.5 have been upgraded to 4.0.

  I want to confirm is that I can add a shared LUN of VMFS3 existing to the new host of 4.0 without the host 4.0 formatting or otherwise destroy the VMFS3 data store and the VM 75 who live on that.

  Looking at page 10 of the guide to upgrade, it says "no VMFS upgrade is required if you are upgrading an ESX3.x with VMFS3 data warehouses, then I guess it's ok. I guess that I didn't know, what if I shared a LUN exist with a new server, ESX4, whatever this scenario changes?

  Thanks for your help.

  I want to confirm is that I can add a shared LUN of VMFS3 existing to the new host without the host 4.0 4.0 formatting

  That's right, what ESX 4.0 is non-destructive, unless you explicitly tell it to erase / format partitions.

  If I shared a LUN with a new server, ESX4, change something about this scenario?

  I don't know exactly, but ESX version 3.21 of VMFS, 3.03 3.02 introduced 3.31 VMFS.  ESX 4.0 is as 3.41 (I THINK), but it does not matter they are ALL compatible, these are revisions minor and no need to reformat.

• Best practices for creating data warehouses

  I have 10 iSCSI LUN (all on the same device), each 1.8 size to which I want to introduce ESXi to create data warehouses.  Are there all recommended for how I divide these LUNS to the top, or should I just do a giant data store?  Maybe there are performance factors to consider here?

  If I had to do 10 1.8 data stores to I can see a problem on the road when I need to expand a vmdk but cannot because there is not enough free space on the data store, it would be less of a problem if I had a giant data store at first.

  Thank you.

  First of all, it's one of those type questions "how long is a piece of string.

  It depends of course of the VMDK number you're going to be running, the available storage, the type of storage, IO, storage, type of virtual machines etc. etc. etc.,

  Things to consider are for example, you have a storage that deduplication and storage cost a major factor (and so on)
  Of course. . almost always, a cost reduction is equivalent to a drop in performance.

  In any case, a rule very loose, I have (in most cases), among which I size LUN somewhere between 400 and 750 GB and rarely (if ever) have more than 30 VMDK per LUN.

  Almost always, redirect the request to the following resources:

• List of virtual machines in data warehouses

  Hi all

  I want to list all virtual machines in warehouses of data starting with "MDF".  I tried

  Get - VM - Datastore (Get-Datastore-name MDF *) | Select-object - property name, data store > VMplusdatastore.txt

  But it does not list the names of data store for a reason any?

  Also some VM will have records on more than a logic unit number - I suppose that it is not translated here?

  Wouldn't be better to do the opposite?

  Hi Simon,.

  the problem with your script is that the virtual computer object does not have a property data store. That is why the data column store is empty in the output. The following script will combine virtual machine names and the data store for all with names beginning with MDF data warehouses:

  Get-Datastore -Name MDF* | ForEach-Object {
    $Datastore = $_
    $Datastore | Get-VM | ForEach-Object {
      $Report = "" | Select-Object -property Name, Datastore
      $Report.Name = $_.Name
      $Report.Datastore = $Datastore.name
      $Report
    }
  } > VMplusdatastore.txt
  

  If a virtual machine disks on multiple data stores, it will display all the combinations.
