• Size of data store for just an OS LUN?

  This seems to be a silly question for me, but the alarm is shake me up.

  If I want to create a data store that is just a LUN for an OS only, what size does?

  For example, in the construction of a Windows Server 2008 R2 machine, I created a LUN on the SAN for just the OS and set it to 50GB.  Then, in vCenter, I add the storage to the ESXi hosts as a data store (lets call it OSLUN).  Then I create a virtual computer and use OSLUN as the hard drive, 40 GB provisioning (think that is all I need).  Now, because I chose 8 GB of RAM, the total of the VMDK ends up being 48Go.  vCenter launches an alert to 'Use of data to drive store' saying 49,75 GB it remains only 1.24 GB.

  It makes any sense to me, except the alarm that makes me think I'm somehow running out of space to store data... should I just ignore this alarm?  I do not see how I'd go on the space allocated for the LUN of the OS.  :\

  Unless you were to store these things on different sets of pins he won't have too much difference. Keep your environment as simple as long as you can. Adding to the complexity when it solves a specific problem not only because you can.

• Block size of data store

  Hello

  First time post and quite new to the product.

  Does anyone know why the option of block size to store data in the client default vSphere to 1 MB in size?  I see in the tutorials and blogs, there are options in the updated section in shape for up to 8 MB?

  Thanks for your help.

  Hello, welcome to the communities.

  Here is some information on the sizes of block VMFS and their constraints;

  VMware KB: Block the size of a VMFS data store limitations

  VMware KB: Frequently asked Questions on VMware vSphere 5.x for VMFS-5

  Don't forget, when you upgrade from an earlier version of VMFS, the block size is preserved. Newly put VMFS-5 data warehouses have a unified 1 MB block size.

  See you soon,.

• Add the total size of data store and space remaining

  
  Hi,
  
  What would be the easist way to add the total datastore size and remaining datastore size to the following.
  I do emphasise, esasiest, since I'm as green as can be to powercli, powershell for that matter. I'm trying to learn in babysteps 
  
  

  Get - VM $VM | %{ $_. Name; ($_ | get-datastore | select name). Name}

  At the moment I get day like this, I get to the above.

  DataStoreName (Add info here on DS size?)

  vmname

  DataStoreName (Add info here on DS size?)

  vmname

  ...

  ...

  ...

  Thank you!!

  The $_ represents the object that has been passed through pipeline (the ' |') of the previous cmdlet.

  For example

  Get - VM | %{$_. Name}

  The cmdlet Get - VM will get all the VMs on the servers of vSphere to which you are connected.

  The pipeline ('|) ') said these VM objects one by one to the following code.

  In what is a Foreach-Object (alias is '%') who will send the name of the virtual machine (available in the variable $_) to the default output.

  On a Select-Object cmdlet, you can select properties of the object that was passed through the pipeline, or you can use what is called a "calculated property. Such a calculated property consists of a pair of hash, name (N) and Expression.

  Obviously, name is the name you want to give to this calculated property.

  Expression is the block of code that must be executed.

  For example

  Get-Datastore. Select Name,@{N="CapacityGB; E={$_. CapacityMB/1 KB}}

  All database objects are passed to the Select-Object cmdlet.

  The Select cmdlet displays the name of the data store, and it will display a property called CapcityGB, which displays the ability to store data in GB.

  Notice how the property CapacityMB that is present in the data store object is converted to GB by the code in the Expression block.

  The part of the Expression has not always need to do something with a property of the object that was passed.

  For example

  Get - VM | Select Name, @{N = 'Current time'; E = {Get-Date}}

  In this case the Select-Object cmdlet displays the Name property of the virtual computer object that has been sent.

  And it will display the current time as the propertyname "current time".

  This is an example of a calculated property that has nothing to with the object passed through the pipeline.

  I hope that clarifies the code a bit.

• Size of data store on smaller clusters

  I have a bunch of data stores in the range from 500 to 750 GB on a 3 host cluster. The SAN is a group of equallogic, which designates a raid by box group. With the latest firmware installed it is support VAAI.

  Is there a reason for me at all do not use warehouses of data of size max? I don't see an issue with about 50 VM and VAAI scsi reservations.

  -Anders

  You will have a depth of queue device and multiple LUNS means also several queues indeed. Even if it's the same raidgroup you will avoid always fills a single queue and hurt all your virtual machines.

• Size of data store

  I have a dell poweredge 2900 with a 12 to raid 5. OK, I installed esxi. However it is to see the CT 12 but when I try to use it it says only 768 AMS are available. I think that the maximum size is 2 TB for esx and esxi. I was hoping to get esxi build a data store on the raid to the limit of 2 TB. Ideally, I wanted more than one partition on the raid 2 TB. is there any hope here. What is my options to use this server. Im a pretty new on this product and would appreciate some guidance on how to run esxi with this 12 to raid array.

  Thank you mark

  Datastore ESX/ESXi VMFS LUNS must not be greater than 2 to 512 b size... You'll want to use the configuration tools RAID (bios level generally) to carve up the storage falls within these parameters.

• Increase in size of data store ESXi after increasing the size of the LUN

  Hi all

  Scenario is as follows.

  Remote site with Dell r710 ESXi 4.1 servers 2, 1 Dell MD3200i SAN with 12 600 GB drives.

  Initially when I implemented the San, I created 2 LUNS with 1 TB in each LUN.

  Now, we ran into a situation where we have 1 server which is now need more than 1 TB of sapce on it.

  I've reconfigured the table and now have a unit number logic that I spent in 2 TB to 1 TB and I now need to increase the store of data on the ESX Server.

  If I increase the size he reformatted the LUN whole or just the free space that I create?

  I don't want to remove any exisitng s VM on the SAN.

  maximum size of a vmfs is 2 TB-512 b only. extend wouldn't format the LUNS. Look at this blog: http://www.yellow-bricks.com/2009/03/26/resizing-your-vmfs-the-right-way-exploring-the-next-version-of-esxvcenter/

• Swapping hard drives for change/increase the size of the data store

  Hello:

  I have an ESXi host 4.1 with 2x146GB RAID1 array (datastore1), 4x300GB RAID5 array (datastore2).  I need more space so I intend to replace 2x146GB by 2x2TB.  I'll first move virtual machines from datastore1 to datastore2, then stop the machine, Exchange records and build the new table.

  • What I need to remove ESXi cfg datastore1. before you physically remove the drives, or will start ESXi gracefully and allow me to remove the data store?
  • I'll be able to add the new data store (2x2TB) to ESXi, ago, i.e. ESXi should see table once initialized on the machine?
  • Existing data warehouses have 1 MB block size max vmdk is 256GB.  I want the new data store to have the block size of 8MB so I can have more VMDK.  I think I can fix the block size of data store when it was created, are, i.e. the ESXi installation can have warehouses of data with different block sizes, are?

  
  

  Thanks a lot for the ideas you have!

  1.) why not just delete the GUI data store before you remove the discs?

  2.) If your controller has the disks properly there should be no problem with their detection.

  3.) Yes, each data store may have a different block size. The block size can be selected when creating the data store on disk/LUN.

• Increase the capacity of data store, which with the block size?

  Hello

  I am trying to expand my datastore 2 TB, I added a new lun 2 TB of the FC SAN TB 4 even and there is no problem adding this in the existing data store.

  But the existing data store is formatted in VMFS3 with a block size of 4 MB for a maximum file size of 512 GB. But when I try to extend the data store to select the size of the block is set to 1 MB and disabled.
  The measure automatically takes on the size of the original block or wil he get a block size of 1 MB? There are some > 256GB files on the existing data store and I think I'd get a strange behavior, if half of the data store is 4 MB and the other half is 1 MB blocksize.

  Can anyone confirm that the blocksize wil be the same for the measure?

  I can also make a second warehouse 2 TB one manually fracture the virtual machine on 2 data warehouses. is there any advantages or disadvantages to this approach?

  Don't you worry, add an item to an existing data store certainly will not change the size of the block. In any case, if it is an option that you can use two data warehouses, I would. With two distinct data warehouses that you will not only be able to spread the load on each of these LUNS but also avoid the complexity. With ESXi 5 (VMFS-5), a single LUN can grow up to 64 ~ to without needing extensions.

  BTW, a 4MB block size allows 1 TB less than 512 bytes.

  I see the barebone specification and seem that your controller is a 'soft' RAID

  Take a look at the configuration of the SATA controller.

  When your drive will be recognized as/dev/sdXX, then you can create your data store.

• Orphan data store

  Howdy! We have a very minor problem with the removal of a data store ancient and inaccessible. The pleasure is gone, it appears same for one of our admins. It was a local storage on one of our 3 old hosts. Since then, we have moved to a SAN implementation with 4 new hosts. The data store is as inaccessible, which makes sense since the host used store is no longer in production.

  Disassemble is greyed out, and there is no host associated with the Bank. There is an old VM that has since been moved to a new SAN data stores. I double checked by starting a migration of data store = > advanced on the virtual machine and verified that the files of the virtual machine are not pointing to the old store.

  I have two questions. One, how in the world I have remove this entry in my list of data warehouses. Two, why would he appear for me and another admin, but not the 3rd admin?

  
  Thank you
  Brenden

  I have it! I had to delete the associated virtual machine to inventory and re-register again.

• 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

  Travis

  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.

• 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

  I found this KB: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1003565

  And it seems to imply that the size of the block can be a problem. Block size for the data of my ESXi store is set to 1 MB, which is expected to support upward

  up to 256 GB. I can't imagine that I need more space.

  On a different note, would you please tell me how I can post a couple of groups? What is the policy on this?

  I took a glance at the file unit .ovf and given the size of the virtual disk that is required for the data disk rose from 60 GB to 100 GB with update 1.

  It can work to tweak/change the .ovf file, however, in this case I would simply create a larger store of data to meet the requirements for the virtual disks (25 + 100 GB + overhead).

• 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.
