VMFS Datastore 3.33 more than 2 TB?

• Secondary VM cannot start if more than 4 x 2 TB VMDK are connected

  Hello world

  a client running a small cluster of vSphere Standard 6 two nodes. Each server has three warehouses of data, both with ~ 400 GB and a data with 18 to store.

  ESX1-Datastore1: 400 GB

  ESX1- Datastore2: 400 GB

  ESX1- Datastore3: 18 to

  ESX2-Datastore1: 400 GB

  ESX2- Datastore2: 400 GB

  ESX2- Datastore3: 18 to

  Each course ESXi has a HP StoreVirtual VSA, residing in Datastore2 and each VSA has a 300 GB VMDK attached. The ASB are used to provide a small 250 GB shared VMFS. VMFS are all version 5.61 and they are not updated since previous versions of VMFS.

  Today, I tried to protect a computer virtual with VMware FT. The configuration of this virtual machine, call the VM1, is stored in a shared VMFS data store. VMDK data is stored in ESX1 -Datastore3. During the FT of the vSphere Web Client configuration dialog, I chose the datastore to VMFS shared for secondary VMX VMs and the switch file. The VMDK of data must be stored in ESX2-Datastore3. I finished the configuration dialog box and everything was fine. A few seconds later the virtual machine was protected by VMware FT. I removed the IP protection and added VMDK to provide 16 TB (8 x 2 TB VMDK, SCSI0:3 until SCSI0:10). I went through the dialog box Configuration FT vsphere Web Client, I chose the VMFS shared for secondary VMX VMs and file to separate again. The VMDK of data must be stored in ESX2-Datastore3. A few seconds later, an error has arisen ESX2-Datastore3 has insufficient disk space, and so the secondary image on ESX2 VM could not start. Just to be clear: 16 TB were allocated in ESX2-Datastore3, and 2 TB were free. And VMDK data were stored in the file ESX2-Datastore3, no Exchange or similar. All the other data stores also had sufficient disk space. I disabled it FT, removed one the 2 TB VMDK and tried again. And again, I have been informed that ESX2-Datastore3 does not provide sufficient free space on the disk, in order to respond to my request to start the secondary virtual machine. With 4 x 2 TB VMDK (and two VMDK for operating system and applications, so in summary 6 vmdk) and in the amount of 8 TB, the secondary VM was able to start. I added a 5th 2 TB VMDK and again the secondary VM could not start.

  My question is: why? I know that I can use only 2 TB. VMKDs no problem. But why can't add more than 4 x 2 TB VMDK? Maximum configuration for ESXi 6 told me I can have up to 16 disks with VMware FT. Is there a maximum storage limit that can be added to a virtual (e.g. 8TB) machine

  Thanks for the tips!

  You can tell your client:

  • This behavior is a defect.
  • VMware has reproduced it is internal and is currently working on solutions.
  • The only way to get this to work at the same time, it is that the data store that contains the secondary VMDK must have at least as much free space as the size of the VMDK (in other words, the free space above the space needed to store the secondary VMDK themselves).  So in your specific customer scenario, if data warehouses were 32 TB or more, then he could add the 16 worth of storage to the virtual machine.

• VMFS datastore and advised LUN (IO queue)?

  Hello

  I have a few quick questions regarding best practices SAN LUNS and VMFS data warehouses.

  Assumptions:

  1 iSCSI SAN (single storage processor)

  2. 2 disk pools (2 x RAID5 @ 3 discs/RAID5)

  3 4 LUNS (LUN/Disk 2 pool)

  4 LUN size: 500 GB/LUN for a toal of 2 TB of storage

  Question:

  1. on what data store VMs would have a larger disk performance?

  A. Datastore1 created on LUN0 on disk pool 1 and Datastore2 on LUN1 on disk pool OR 1

  B. Datastore1 created the LUN0 on disk pool 1 and Datastore2 created the LUN0 on disc 2 of pool?

  I guess what I'm trying to ask here is to have LUNS on clusters of separate drives faster than to have all the LUNS on the same disk pool? If A VM hard exists on Datastore1 of B above, setting hard of VM B on Datastore2 of B above would improve the overall performance for both virtual machines? On the other hand, respectively, capping A VM and hard of B VM on Datastore1 and Datastore2, of A above still an effective option? This brings me to question 2.

  2 - is data on separate warehouses LUN fracture the queue of e/s of SAN LUNS on all LUNS? In other words, the SAN will access all LUNS at the same time, thereby increasing the performance vs having all VMs on a single LUN shared with a single e/s queue?

  Thank you

  In General, you're trading the guaranteed 90 IOPS / sec per IOPS VMDK / s maximum 180, but shared between 2 VMDK.

  This seems to be an entirely theoretical question and sometimes almost philosophical, whether for trade this broad for this.

  If you think about it more later, it is quite similar to place vCPUs and VMs on ESX host - is it better to share some CPU more Rapids (= more expensive systems) or gives a processor dedicated Basic (= more material)?

  If I stick my neck, I would say that the difference between the aforementioned buildings is visible only marginally and you could probably be very happy with a flat 6 pin R5 datastore as well.

  But the specific difference between 2 R1s and an A10 with 2 LUNS or even a R10 with 1 LUN but 2 VMDK worth thinking.

  As I've already said:

  If speed and performance is a problem (MSSQL IOPS requirements) then you're already wrong with the SATAs and plan instead to study in an array of more powerful than to try to get the last bits of your SATAs.

  Don't get me wrong, surely SATA can do miracles in the small environment, but especially if I notice a 50 GB DB MSSQL for P2V I would first collect some perfmon data and plan my storage as a result even more than I would normally do in SMB environments.

  You will not get a PRIUS to take the load of a SUV, no matter how long and diligent, you plan to distribute the load.

• ESXi 5.5, 5 VMFS datastore / vmdk size question

  Trying to check that I understand the vmdk for esxi 5.5 size limitation.

  If I have a VMFS 5 existing on my 5.0 esxi hosts, data store once I update my hosts to esxi 5.5 that I would then be able to have vm with vmdk is greater than 2 TB?

  I don't have to create new warehouses of data VMFS 5 after the upgrade to esxi5.5 take advanrage of the change in file size limit?

  Thanks for any help.

  That's right, at least in part. In addition to the upgrade of the host, you must also upgrade the hardware version of the virtual machine (Compatibility Mode) to take advantage of larger virtual disks (up to ~ to 62). However, always keep in mind the time needed to restore the virtual disk together where this is necessary. With 1 Gbps - assuming that you have the full available bandwidth - 2 TB will require more than 5 hours already! Then maybe organize the data in several virtual disks may be a better solution.

• More than a store of data in the list

  Hello

  The following script works fine except it does not show VM with more than one data store:

  Get - VM | Select Name, PowerState, @{N = "SnapName"; E = {}
  ($_ | Get - Snapshot). Name}},@{N="datastore '; E = {}
  ($_ | Get - Datastore). Name}}, @{N = "TotalDisk"; E = {}
  ($_ | Get-hard drive | measure-object-property CapacityGB

  -sum). Sum}},@{N="GuestOS '; E = {}
  ($_ | (Get - VMGuest). OSFullName}},@{N="Cluster '; E = {}
  ($_ | Get - Cluster). Name}}

  How it can be changed to the VM list with more than a DS?

  Thank you

  Hello, AGFlora-

  You can change the property calculated for the property to store data such as:

  @{N = "Datastore"; E={($_ | Get-Datastore. %{$_. {(Name}) - join ","}}

  This will make a list separated by commas in the names of stores of data on which the virtual machine and its discs are and should work for virtual machines residing on any number of data warehouses.  What to do for you?

• Maximum VMs per VMFS datastore

  Can someone explain to me why the general rule concerning the number of clones linked by VMFS datastore is supposed to be 90, safer at 60? (39:00 in the video)

  My VMFS data store can handle more IO wise and wise, so why would I limit this number of storage? Numbers wise, I can run 120 VM out of a 2 400 GB data store.

  Here are estimates based on the data accumulated on the ground.  If you can get a larger number, it's fine.  These figures will be based on the IOPS / s, its use for the end user, locking, back-end storage, etc.  Basically the storage i/o profile of the entire group of the Active Desktop disk activity goes beyond what the back-end data store is able to provide.  If there is no offset in a desktop experience virtual because the affirmation of storage, revealed by tests or the use of your actual deployment, the number of clones linked by the data store can be merit to be studied.  For starters, these figures are given for the initial orientation.

• Cannot extend VMFS datastore

  Mary!

  I have a virtual machine with two partitions. Partition for the system (IDE) and (SCSI) partition for data. The partition of SCSI has there own underlying the LUN on a storage. LUN capacity was 50 GB where the VMFS data store uses almost the full ability of LUN (49, 75GB). So I developed the LUN on the storage of 60 GB and now I want to extend the data on this LUN VMFS store and add a few more GB. But although I can see the raw capacity (60 GB) of the LUN in storage/properties for this VMFS datastore I can't expad the datastore to VMFS himself. When I click on expand I get no device/LUN to use.

  Any suggestions?

  And my main goal is to expand the data store VMFS.

  It's exactly what I got. When you log on to an ESXi host (using the vSphere Client and the root user), you will have the same storage Wizard dialog box as in the screen shot you posted before. After logging in, go to 'Configuration'-> 'Storage', select the datatstore VMFS, you want to develop and run the wizard.

• Failed to create full-size VMFS Datastore on large virtual disk on Dell R710 5 2 t + 1, Raid 5 PERC6i controller

  ESXi4, I installed it on my Dell R710. She has 6 1 TB on PERC6i SAS drives, 5 discs do Raid 5 with hot spare disk 1. And I created 3 VD, 1 is from 40 GB to install the OS, 2 is 1 TB to contain the model ISO and VM and 3 is 2.6 TB to contain the VM.

  After installing ESXi4, I found only 2 created Datastore: 2. 39 GB 1 Datastore and 1 TB data store no data store has been created on the VD 2.6 TB.

  I tried to create it manually, but I found that only 635 GB in size can be created on this 2.6 t. Why? As I remembered ESXi4 can support up to 64 TB VMFS Datastore.

  The BIOS is 1.0.4.

  Someone had the idea?

  Take a look at this "vSphere and 2 TB LUN has changed VI3.x.

  http://virtualgeek.typepad.com/virtual_geek/2009/06/vSphere-and-2TB-LUNs-changes-from-vi3x.html

  Oh, a data store to 64 would consist of 32 degrees to ~ 2 TB. The limit on the size of the LUN behind the data store is 512 b less than 2 TB

• How can I view more than 150 emails in Mail on iPhone with iOS 10 7?

  Since the upgrade to iOS 10.0.1, I can no longer view more than 150 e-mail messages in a folder.  This happens with IMAP accounts as well as my iCloud email account.  Before iOS 10, with accounts IMAP, when you sailed until the end of the list of messages, the phone would then charge a 150 additional messages from the server.  With iOS 10, this happens.  Thus, on e-mail accounts that I have on the phone who do not receive a lot of messages through the day, I post only 1-2 days of e-mail messages.  The same behavior is experienced on iPhone 7, 6 s iPhone and iPad Mini 3 - all iOS 10.0.1 running.

  Hi there RickNY,

  Welcome to the communities of Apple Support!  I am happy to help you with your iOS devices does not not more than 150 messages after updating to iOS 10.  I know how it is important to be able to access old emails.

  I would like to begin by consulting a setting in Mail.

  1. Go to the settings app
  2. go to mail > THREADING
  3. Make sure you have organize by live wire (green)

  Please check your Mail application and see if you are now able to load older messages.

  Best wishes!
