• VMware ESXi 5.1.0 VMFS5 maximum data store size

  Hi all

  I read white papers on VMFS and I get conflicting answers on the maximum size of a VMFS5 data store.

  We are using a Dell EqualLogic PS6100 and linking the LUNS via iSCSI for host servers.

  I need to create a data store TB 4 for my file server reside on.

  (A) is it possible?

  (B) are there performance problems with the largest data warehouses such as I want to do.

  Block sizes C) must be modified to mount a data store of this size and how you do it.

  Any idea or article links would be greatly appreciated.

  Keith

  (A) Oui it is possible but you will need to use a RDM - ESXi 5 allows access to 64 TB but the size of the virtual disk is always capped at 2 TB - 512b

  (B) you must not

  (C) with ESXi 5 block size is no longer a variable that you define for a VMFS data store

• the maximum size of the data store in ESXi 4

  as I don't have a lot of space left on my data vmfs3 store, plans to add a 3 TB of HDD to the ESXi 4.1 Host. I will then use the new HDD for a creation of a new data store.

  I also want to ensure that the block size is the same as the existing data store.

  Please notify.

  Thank you.

  The maximum size of the LUN/disk in this case is 2 TB less 512 bytes (see KB VMware: ESX/ESXi 3.x/4.x hosts don't support 2 TB LUN for more details). The maximum size of virtual disk with a block size of 4 MB, please take a look at the article I mentioned in my previous post.

• ESXi data store set to a maximum of 35 GB?

  Hello, I have ESXi installed as a virtual VM Workstation 9 machine and connected with vSphere.  If my laptop has 196 GB of free space, why my ESXi data store is set to a maximum of 35 GB?  I can increase 100 GB?

  How much space is allocated in vmware workstation to esxi virtual machine?

  probably of 35 GB

• Maximum limit of data store?

  Hello

  The Datastore maximum limit is 2 TB-512Bytes in vsphere 4 using the block 8 MB size.

  What is required of 512Bytes since the 2 TB data store? Why we cannot allocate 2 TB?

  the KB below seems to explain this:

• VMX file larger than the maximum size supported by the data store

  Hi all

  I seem to be getting a strange error trying to a virtual machine that is located on a snapshot VMFS5, to the data store format.

  The virtual machine (VMDK and VMX file) is installed on a thin provisioned 2 TB datastore which has the value VMFS5 formatting.  It is a data store new with no other VM on it.  I had problems in the past with the datastore block sizes (1 MB, 2 MB, 4 MB, 8 MB on VMFS3), however, I thought that VMFS5 got rid of the question, since it's all blocks of 1 MB and all files in the virtual computer are on the same data store.

  The error I get indicates that the VMX file is too large for the data store (used Im saying "unspecified file), however, if I do the independent 2 TB disk snapshots through the fine.  The virtual machine has two virtual disks, a 50 VMDK of GB and a thin 2 TB VMDK (200 GB used).  I tried fast vMotioning the VMDK and VMX to other data formatted VMFS5 stores and still get the same error.

  I'd appreciate any help and ideas.

  Thank you

  Although the block size limit is party, maximum 2 TB file size less 512octets still exists. Since a Flash disk can grow waist put in service the basic disk more overhead for the metadata, the maximum size of virtual disk - to be able to create snapshots - is 2032 GB.

• < Unspecified file name > file is larger than the maximum size supported by the data store ' < indeterminate datastore >

  Hello

  I use vSphere4 and I'm having problems, create snapshots of virtual machines.  I get the following error when I try and take a snapshot...

  File & lt; filename not specified & gt; is larger that the maximum size supported by the store data "& lt; not stated the store data & gt;

  If I check all disks assigned to the virtual machine, the block sizes are ok.  All the disks are of block size of 1 MB and less 60GB, except one that is 600GB and a 4 MB block size.  There are also free space on each data store with being less 5,30 Go which I guess should be much more than enough to create a snapshot.

  In addition, whenever I try and create a snapshot, it creates a file called SERVER - Snapshot1.vmsn, 2, 3, 4 etc. on the main data store.

  Is it possible that because of the single disc of 600 GB, VMware prevents me from taking a snapshot?

  Here is the config...

  See the attached file for disk configuration information.  Operating system drive is the drive where the snapshots are created.

  Basic disks refers to all disks assigned to the virtual machine. Given that, by default, the snapshot is stored the vmx file, this data store should be able to potentially create a VMDK your largest disk size, assuming that you change every block in the vmdk.

  In your case, it should support a snapshot that can potentially reach 600 GB to one of your drives, and so needs a block of size on the VMFS volume to support this. You can redirect the snapshots to another logic unit number and so to work around this problem (Storage VMotion is another option) limitation.

  Trust, this clears up a little.

  I have read that I need to increase the size of the block, but I need to remove the data store. Is it the same on ESXi 4.0?  I have 4 other VM about 150 GB. Please tell me I'm wrong.  Please...

  Same rules apply.  Create an another LUN with the correct block size and away files or hang the lun and recreate

• file is larger than the maximum size supported by the vmware data store: snapshot fails

  Hello

  I'm having a few problems when creating a snapshot either by Veeam/vSphere client...  Here are the details...

  VM is connected to lun 2 TB RDM in virual Server files mode. The configuration file is located on the datastore to vmfs with 750 GB (block size of 8MB)

  I'm not sure whether the size of the data store creates a problem or anything else.

  All advice is appreciated...

  Thank you

  What is the exact size of the RDM? A snapshot requires little additional space for hard metadata. Please take a look at http://kb.vmware.com/kb/1012384 (section: load calculation required by the snapshot files). For your ROW, this means, if the ROW is greater than 2032 GB, you will not be able to create a snapshot.

• < unspecified file name > is greater than the taken maximum size supported by the data store ' < indeterminate datastore >

  Hello

  I made a mistake.

  Block size was set at 2 MB, vmdisk 500 GB value has tried to bring to 600, do you have a message that it was not possible. VMDK was set to 512 GB after that operation is completed. The server is Windows 2003. the 11 additional GB, which is not allowed is visible to the guest OS. But I have not developed the partion with diskpart.

  The problem is that this snapshot of the operation failed. This is an easy way to decrease the vmdk to the original size of 500 GB (if possible without turning off). Without destroying the files.

  Thank you very much

  Solution 1 works if you have a second data store with the appropriate block size (4 or 8 MB)

  Solution 2 - as you said - requires additional disk space and stop times

  A possible solution (3) would be an upgrade to vSphere 5 allowing - after the upgrade of VMFS-5 data store - virtual disks with up to 2 TB less 512octets regardless of the size of block that exists. However, you must ensure vcenter Server as well as guests, access to the database are upgraded before the upgrade of VMFS data store. Also make sure that any 3rd party applications (eg backup) you use, support vSphere 5.

  Since you mention a LUN to Solution 2, I assume you are using a shared storage. You do not have the opportunity to present a different LUN for guests, that you could get in shape with the block of adequate size and then cold migrate the virtual machine to it?

• ODI file data store

  Hi all

  I have a confusion about the physical and logical length in the ODI file data store.

  I have a fixed-width file where a c2 col had datatype as string (30).

  I've set this column in the data as string store > physical length 30 > logic length 30

  My interface failed with error as '.

  ORA-12899: value too large for column 'S0_IDM '. «C$ _0S0_EAGLE_DWHCDC_CHRG_MST ".» "" "C2_CHARGE_DESC" (real: 31, maximum: 30).

  When I increased the logical length to 255, the interface worked fine.

  Being always the same 30 physical length.

  How different is it?

  Any help on this will be appreciated.

  Thanks and greetings

  Reshma

  This isn't the official documentation, but here's my point of view, after a few moments of reflection

  Everything you do in the ODI Designer is inspired by the logical architecture. Only when running it manifested in a physical implementation i.e. connection strings are materialized etc. When you perform an integration ODI creates usually a few temporary tables prefixed with C$, I$ etc to be able to perform the necessary data movement and the transformations needed to, for example, to fill a data target (table) store. In your example, your flat file is materialized in such a temporary table before that its content is manipulated (or not) and loaded in the target data store. When ODI generates this code that he uses the logical length emitted in the DDL that generates temporary table column lengths, the physical column is ignored.

  Now in your scenario is not a problem as constraints such as these do not matter to the physical file version knowledge if you were to write to the file, that it would not matter if you wrote return 255 characters or 31. This could be a problem if you were using database tables and varying the logical vs physical lengths but generally you reverse engineer tables from database using ODI rather than manually doing so makes better.

  Anyway, in short, I think that the logical lengths should be taken as representative which will manifest itself in the materialization of the temporary objects used to manged / transform the data from the source models (tables$ CAN) and target (I have tables$) while the physical lengths indicate what the underlying physical representation of these models are in reality.

  EDIT: after reading some logical documentation actually represents the length while physics is related the number of bytes required to store the data. Therefore, you could have a situation with multibyte characters where the physical length could be greater than the logical length but not really the other way around.

• How to make instant consolidation if the data store is out of disk space...

  Hello

  I have a virtual machine that has left many of the snapshot files and now can consolidate using the tool (he always said of disk space to make the consolidation)

  The data store have now 60 GB of free space when the space data store maximum disk is 850 GB and the busy VVMM over almost 700 GB of disk space...

  Can I attach a 3 TB USB drive to the ESXi server and move all the files through or another way to do...

  HELP ~ ~

  With the disk space required on drive E, it may be useful to consider an alternative:

  • create a (much smaller) another virtual disk
  • Stop all of the services entering drive E
  • Copy the data from drive E more to the new virtual disk (for example using robocopy)
  • switch drive letters
  • Once everything is working as expected, get rid of the old virtual disk

  This will not only reduce the disk space used on the data store, but also to ensure that the virtual disk cannot grow more.

• Removal of LUNS in a data store

  I installed a new volume of virtual disk of three 2 TB (RAID5) SAS drives on our HP SAN. So I have 4TB as the disk capacity that LUN. Now I was ignorant of the fact that the maximum size of a data store for ESXi 4.1 2 TB - 512 bytes. So when I added this new 4 TB LUN to a store of data on ESXi 4.1.0, only 1.64 TB has been appearing as available as against 4 TB or 3.64 to capacity. Now, I want to delete this new LUN of this data store and return to the utility of HP storage to recreate smaller i.e. two 2 TB LUN management. However, the problem I have is, I don't know how to remove this new LUN in the data store to which I added this without losing data or a data store. In my case, I had a data store 300 GB to 1.09 and I added this new 1.64 TB LUN to this Datastore.But I want to delete this LUN data store. Thank you, Clément

  I'm afraid there is no way taken in charge to remove a measure from a data store. If you want to use the entire disk space, you must destroy the entire data store.

• ESXI & HP VSA data store size

  Is - well configured?

  I have 2 hosts HP DL360P VMware 5.5 with 2 500 GB hard drives with hardware raid 1. iSCSI data store configured with 690 GB of disk space in vSphere. 2 HP VSA is appearing 350GB of storage available. The HP CMC shows 690 GB of available disk space. When I install the volume, RAID10, and available disk space as thick, it shows a maximum of 347GB - because of RAID10 storage space.

  My concern is the gap in the amount of available storage space depending on whether display you the data in vSphere (690 GB datastore) store and the CMC showing only 347 GB of usable storage space. So in vSphere it will probably lead someone to believe that there are more storage available there are currently available on the volume.

  Is something wrong with that or should it?

  Mystery solved, someone has decreased the size of the volume in the CMC, which explains the difference in size.
