• Reference Dell MD3000 virtual disk

  I have an environment to both nodes of ESX 4.0 and a shared storage (Dell MD3000, no iSCSI).

  On storage, I have 10 at 10K SAS drives.

  Virtual disk how I need to build? A two bigger or smaller?

  Thank you

  Max

  It is not a simple answer, because it depends on:

  • Good storage practices

  • Storage type and the type of disks

  • VM number, size and type of e/s

  • Max VM and e/s per LUN

  • Size Max LUN (less than 2 to - 512 b)

  In your case, with 10 discs and two nodes and storage running in active-passive mode, you can create 2 virtual disks.

  Create 2 different groups of RAID5 (also think about using 1 disk as a global hot spare) and in each virtual disk group build 1 (or more if the size is more than 2 TB - 512b).

  If you have a few VMS with high IO think also to use use 4 disks in RAID10 instead of RAID5 configuration.

• Feature suggestion: virtual disk via USB hot

  I suggested this feature in VMWARE 2 years, I had not seen this be taken seriously. But I insist it is very useful and would it make Workstation & other products much more powerful convinent server for users.

  Essentially now existing virtual disks cannot be ADDED to a virtual machine as an IDE or SCSI drive, this must be done after the virtual machine is stopped. Thus, it is not hot.

  The equvilant material action REAL hot plug is to plug your physical hard drive via a SATA to USB adapter and connect to PC and PC will detect a new USB dive. For a VITURAL Machine, I takes VMWARE to write a function to CONNECT a virtual disk available (all files hard) in a VM running via the USB interface.

  VMplayer and workstations can now connectable to warm physical USB readers of thumb, but not no virtual disks, it's a shame. It would be a feature very very handy and popular because there are so many things, that you can do with it.

  Without this feature, users will have to turn off the virtual machine and fix the existing virtual disks and then after use, turn off again to remove them.

  Attachable to hot only saves a lot of time.

  I mean WHY NOT? VMWARE should really consider this, I hope.

• How can I remove a virtual disk partition?

  Well, basically, I was using the program - Ramdisk, and it takes little memory your just RAM and transforms a partition you can store things in, or use it as a hard drive. But, now, I think he's using for many and I would remove it. I used 400 MB of ram, so now it is used. I went to computer management, went to the partition and delete the volume. Now, he says: 5 - base 400 MB drive online, but on the side, where it shows the volume actually score or what ever, it says 400 MB not allocated.

  So now I have 400 MB of ram m unallocated, and I'm trying to find a way to get it back in my ram used! Any help would be greatly please

  You would need to reverse the process used to create the virtual disk - uninstall the software used to create, or reverse the settings that you have invoked in Windows to create, as the case may be.  Just delete the disk partition RAM does not remove it from memory.

• What is the maximum size of virtual disk in machines virtual esxi 4.0

  I am trying to create a virtual disk to a virtual machine, I want to make the size of the 300 GB disk but its not allowing to create.

  Can I know what is the maximum size of virtual disk, we can create in machines virtual esxi 4.0 with vmfs3 partition

  
  

  The maximum size of the virtual disk that you can use depends on the size of the selected block when formatting of the data store. With the default of 1 MB block size, the maximum size of virtual disk on a VMFS-3 datastore is ~ 256MB.

  Is there a chance to run ls-lisa from the command line (SSH) in the virtual machine folder and provide the output!

  I ask because I'm a little worried about the timestamp of the hard (May 2011). Depending on the size of the files in the snapshot, it seems that the second virtual disk is not really used by the guest operating system and we could come back manually (by editing the .vmx file) on the resized basic disk (100 GB compared to 75 GB for snapshots) without losing important data!

  If you want to revert manually,

  • delete the virtual machine of the inventory
  • backup and then edit the .vmx file (replace "WEBPDMAPPD_1 - 000003.vmdk" with "WEBPDMAPPD_1.vmdk")
  • Move 3 snapshots in a directory temporary sub
  • Add the virtual machine to inventory
  • create a new snapshot to prevent the current hard files to be modified
  • Turn on the virtual machine

  If everything works as expected, you can delete the snapshot files moved and remove the snapshot created in the Snapshot Manager again.

• Best practices for large virtual disk

  I would add a large virtual disk (16 TB) to use as a backup storage and ideally thin to allow potential available use of, at least initially, a lot of free space.  Headache is the limit of 2 TB for virtual disks in ESXi 5.

  I know that you can extend 2 TB virtual disks in the operating system (win 2008 r2, in this case).  But is it a good idea?  The underlying array is raid 6, so I guess it's safe, but it sounds at least potentially worriesome me on 8 discs.  Not a matter of concern?

  Performance?

  RDM is less flexible and might be impossible (matrix raid is local).

  Anyone have any suggestions on the best practices here?  What would you do?

  I do not recommend the use of the plan span for the file VMDK disks a bad 2 TB and its all parties (several ways that I saw - snapshot problems, corruption etc.)

  Because they are still local drives, you lose flexibility everything that I recommend using RDM.

  A huge ROW for this virtual machine.

  http://blog.davidwarburton.NET/2010/10/25/RDM-mapping-of-local-SATA-storage-for-ESXi/ This departure to configure it.

  As for what I would do, I've done this before and I used RDM, just for 8TB but still.

• Virtual disk or a raw device

  I have a virtualized Netware server.  I need a volume at least 700 GB space.  I have a SAN volume that is 836 Go.  It will be used for the storage of file user.  This could be any type of files.  I'm trying to figure out if make a virtual drive or map with Raw Device mappings.

  If I create a virtual disk, I have to use a block size of 4 MB to get the space I need.  Some files could be several size k or smaller.  I will lose the space according to the size of block?  Can I use Raw Device, or is it important?

  Thank you

  Chris

  Hello.

  If I create a virtual disk, I have to use a block size of 4 MB to get the space I need.  Some files could be several size k or smaller.  I will lose the space according to the size of block?

  "Large blocks do not increase storage overhead as subblocks are used for small files. Subblocks are still 64 KB. "- taken from Duncan yellow bricks.

  Can I use Raw Device, or is it important?

  It does not matter in terms of saving storage space. Either will work fine.

  Good luck!

• VMware Tools: Shrinkage of the virtual disks - what is - this intended?

  Hello

  Maybe I'm missing something, but what is the "Reduction of the virtual disks' in VMware Tools used for?  It seems to me that 'reduce the virtual disks' is the only thing that it does not.

  I have a virtual disk in a virtual machine with Windows 2003 Std x 64.  A 'volume' (a partition on a dynamic disk) disk occupies 10 GB on a virtual disk.  The rest of the space on the virtual disk is not assigned.  I want to "shrink" the virtual disk to recover the unallocated space.  But the function "reduce virtual disks" VMware Tools seems to allow me only to "shrink" the disk volume or partition.  I want to reduce the virtual disk.

  What Miss me?

  Thank you.

  Your best best for shrink disk is to use VMware vCenter Converter.  The fret is more than one optimization tool, a bit like a Defrag tool, but will not reduce the size of the disk of the virtual computer.

• Divide a virtual disk in two virtual disks PERC H710

  Hello guys,.

  -We have a server PowerEdge R720 with a PERC H710 Mini storage controller which has 8 drives 1 TB each of them.

  -We have created a virtual disc, which includes 8 physical disks configured in Raid 5.

  -We have installed Windows 2008 Server R2 and we got 4469 GB no allocated space that we cannot use due to the limitation of the disks of the Basic.

  

  What we really want to do is reclaim the unallocated space of the existing virtual drive and put it in a new one, so that we keep 3 disks for the virtual disk 0 and we use the 5 others for the new virtual disk 1.

  -Is that possible without destroying the data we have?

  -Help please!

  Thanks in advance and sorry for the bad English :(

  Unfortunately, there is no way to do it without restarting.

  Option 1

  What you have described, you could divide drives upward into distinct from VD, leaving a 2 TB or smaller for the operating system.  It will cost you a value of an extra disk to disk space (VD0 RAID 5 = 2 TB, VD1 RAID 5 = 4 TB).

  Option 2

  You can create "slices" on the disks - you still all 8 disks in a disk group, but you would cut a smaller VD for the OS, and then the rest of the disc space can be a VD for data (each VD will appear as a "separate" disk in Windows, so the second VFD can be converted to GPT and be as big as you want While the first VFD remains an MBR disk to boot into the operating system in BIOS mode.  This will give you return a value from an extra disk to disk space over Option 1 (VD0 RAID 5 = 100 GB, RAID 5 = 6.9 to VD1).

  Option 3

  You can switch mode UEFI, create a VD with all 8 disks (as you did), convert the GPT disk, then install.  UEFI is necessary at the start of the GPT disks and GPT is required for disks larger than 2 TB.  It would also keep 7 TB of usable disk space.

  You can also consider a RAID 6, if you can accept the value of another drive 1 TB of disk space.  Since a reconstruction of the drive may take 1 to 2 days or more, a RAID 6 would provide better tolerance to failures and protection during the vulnerable period that the disc is out of line or reconstruction.

• Reference Dell HDS - recommended VMware virtual disk - drives provided - basic and dynamic thin and thick.

  Can someone point me to the literature on best practices for guest disc formats?

  I know all the Compellent thin-provisions. However, in VMware 5.5, when you set up a virtual disk in the comments you have several choices:

  • Lazy provisioned to zero thickness
  • Eager provisioned to zero thickness
  • Provision of thin

  And then, at the level of the OS, you have the choice of:

  • Base
  • Dynamics

  I would like a pointer to the technical document explaining the advantages/disadvantages of each choice and recommended best practices.

  Kind regards

  Kath

  I would like to either thin or thick lazy to zero.  The two will take the same amount of data on the HDS.  The main decision is where you want to manage your storage space?  If dilute you on thin you need to make sure that you make no provision in both places.  If you have thick lazy to zero, then you can only on commissioning on one side.

  Say that I always thin on thin.  Recovery of the space at the level of the virtual computer is not officially supported immediately, but maybe someday.

  In a virtualized environment, always keep it simple.  There is no dynamic performance with virtualization

  Break your table into smaller pieces. ESX requires a minimum of about 10 GB, even if you can make bigger it. ESXi requires only 1 GB. Data warehouses may not be less than 2 TB. You may be able to use virtual disks raid based to break the table.

• Reuse a RAID disk and hot spare procedure

  My questions are for a PE R720xd with the PERC RAID internal H710P controller.

  I have replaced several RAID drives in the past, but I never did this before, so I was hoping to confirm my procedure for hard drives hot swap. A drive failed on one of my live servers. In the past I would always bring back the server during a maintenance window and replace the drive by using the configuration utility to make sure everything went correctly. This particular server has become a system of very high availability, so I was hoping to use for hot spare option do without bring down the server.

  The other issue is that Dell is not in stock on the disk, I need so I intend to use a same car I replaced recently on a server off-production that has already been fixed in a RAID1 in another Dell R720 Server table. Any time, I have never replaced a RAID drive, I always used a new drive out-of-the-box, so I'm also not 100% on how to prepare the drive to use for a new RAID array.

  I thought I am brings the donor server down and come off the drive I want to enjoy this the RAID array server using the configuration utility. So a question is - is there anything else I need to do preparation used in car for use in the new table?

  With respect to hot-swapping which lead to the new array, is it really as simple as just popping one out and put a new in? Can I do to confirm it has taken - apart from just confirming that the lights blink like crazy during synchronization?

  Thanks for your understanding!

  C.Short,

  You can switch the drive, but it will be not just to rebuild there is data on the hard drive. So when this disc is inserted, it will show foreign. You will need to do is to boot to the controller (Ctrl + R) and then CLEAR the foreign Configuration. Once completed, then you will be able to rebuild the disk on the virtual disk, you can do the BIOS of the controller, or from the OpenManage web interface (depending on the operating system).

  Let me know if it helps.

• Md3220 and md1220 combo, how to configure any global hot spare parts.

  The MD3220 is full of 300 GB 15K SAS drives the MD1220 is full 1 TB NL 'SAS' 7.2 K disks. The two boxes have discs 22 & 23 unused in the goal is relief. However all the mechanisms that I use to create hot household simply attaches all four disks to two speakers. I'd rather have two spare drives only protect readers in their own enclosure. Interestingly enough, I asked the software dell 'automatic configuration' (sic) the hot spare and he decided ONLY two use 1 TB drives and use them to protect the two speakers. In addition, I was quite puzzled as to why he also allowed me to do it manually the absurd configuration to allow a 300 GB drive protect a forum composed of 24 1 TB disks. In any case, is it possible to have host associated with a case (or disk group) spare parts. ? Thank you.

  You can't dedicate a hot spare in a picture of MD3k-series. If a hot spare will succeed for any player in any long case that the size of the spare drive is the same or larger than the failed drive.
