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

  • Storage on iSCSI - mounted directly from the VMware virtual disks

    I am setting up a HUB/CASE/box Server mailbox of all-in-one for fewer than 500 users on a Windows 2008 R2 virtual machine and am about to configure the storage I need. The two words that I can't wait to hear more from Microsoft PSS is "not recommended" or "not supported." I have a Dell Equalogic PS6000 and have the ability to 'direct attached' compared to the VMware virtual disks for storage of mailbox databases. We run vSphere with vMotion, etc..

    Using virtual disks bad practice? Advantages or disadvantages I should know about? Adding a layer of complexity that might come back to bite me?

    I have a very similar setup and am currently using directly attached iSCSI volumes EqualLogic berries for my Exchange 2007 mailbox stores.  I also have the role of running UNIFIED messaging that works in fact remarkably well even if everything is running on a virtual machine.

    It was in large part because the EqualLogic recommendations had to use directly attached volumes so that taking snapshots multi-application/replication tools worked correctly.  If the Exchange mailboxes are held on a VMFS volume, then Tools EqualLogic will not be able to get to them.

    Microsoft have been OK on this configuration, and I actually had them made up our VM, one or two times when we iron out some problems of UNIFIED messaging (although I hide icon "VMWare Tools"!).

    The best thing to do would be to create volumes you think you'll need and attach them directly to the virtual machine using the Microsoft iSCSI initiator, and then run the Exchange tool (I forgot his name) to test the storage for speed and capacity.

    See you soon.

  • Reference Dell poweredge r530 - increase the disk space

    Hello

    We currently have a Dell Server poweredge R530, with installed 5 hot swappable drives with RAID 5 configured. I need to increase disk space for our virtual machines, bought an x 2 extra 1.2 TB SAS drives to install. What is the correct process to add 2 new readers to the table and increase the space available in the 2012 R2 windows server? Could someone sanity check process below please:

    1. install the 2 new drives while the server is powered and operating normally. (What I have to install 1 player and wait a while, or two disks can be installed directly after the other?)

    2. go in dell iDRAC and confirm the visibility of 2 new readers.

    3. wait until the readers successfully have been added to the State through iDRAC Tracker

    4. go in the management of the storage within the 2012 R2 server to allocate new space for the virtual machine partitions.

    Is more correct? It feels like I'm missing an essential step, it cannot be that simple that it allocate the additional storage space on a live production server?

    Any advice appreciated

    Thank you

    1. the two drives can be added at the same time.

    2 iDRAC is not the best way to do it. Unless this is your only access to the server, use OMSA leave within the OS.

    3. the process is not automatic. Once readers show up in a State of PREPARATION, you will need to go to OMSA, PERC, storage, virtual disks and select Reconfigure in the drop-down list of tasks available for RAID 5. (In fact make the statement reconfigures / expansion was the 'crucial step' you left on your list of ;).))

    4. Yes.

    Well, tell me how it works,

    I have dell inspiron 15z with 500 GB hard drive with laptop want to exchange it to 120 GB ssd, but I can't because no media to reinstall and the whole system is on hard Bank...

    I tried to do with software usb recovery dell preinstaled originally, but when I start to install the ssd system it gives me the error message that the new hard disk must be at least 465 GB

    I tried to copy the partition that I tried to do the recovery with another software image, it simply does not. When I tried to install win from another cd that he refuses the number series, even when I used the same version. instead of this test of dell to kill my mood why don't they have just not preparing the software backup and restore Dell to facilitate the use and for SSDS too?

    I would gladly appreciate any help

    Hi Thomiq,

    The backup and restore software would seek similar configuration during the restoration. If the hardware is changed the original image may not work.

    At this point, I see that you will need the operating system disc to reinstall it on the SSD drive. Please send me a private message with serial number of the computer, name registered during the system purchase and email address so that I can check out what we can do.

  • Disk and the virtual disk drive records corrupted (code 19)

    I recently had a virus and it corrupted my drive and drive virtual and perhaps deleted records. I tried all methods on the site of Microsoft Support here and not to have borne fruit. I uninstalled the drivers and quite well done all recommended from the page (except run a fix because it cannot find the driver). I also added new keys in regedit and it has not fixed either. Is it possible to replace records that have been corrupted, or missing, or I'll have to do a wipe or something to fix? Thank you.

    Sorry, I don't really know what to do; I guess if you need a tool for editing with screenshots I can do.

    You can check the following registry key? :

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

    Is there a 'name' UpperFilters and LowerFiltersin the registry for this key, in the right window?

    If so, what is 'Data' for these names?

  • Increase the size of the virtual disk drive?

    I have a VM machine running server 2003 with 2 drives inside. When I used the converter to make the virtual machine, I made the wrong each player gradually.

    I can resize the readers in the virtual machine.

    I read somewhere that you can launch VMConverter on the host machine and point it at the machine VM files and create another machine virtual with larger disks. Is this true? If so does anyone have a way too?

    Thank you!

    Yes, I believe you can do this with converter.  However, there are times when converter will make unnecessary changes to the virtual machine that will completely ruin.  So be sure that you have a backup before doing any of this!

  • Reference Dell r710 12core 32 GB super slow with sql and need help exch2010

    Hi all and thanks in advance.

    I have a new r710 which has a great for a few months then it has slowly degraded until now, it's an analysis on all the vm, I can't tell which one is it slows down because all the performance counters show a lot of place in all categories. I've been doing the reconnection to the datastore2 and datastore1, then I get a restored connection. I moved the Exchange 2010 vm to the datastore3 that does not have errors, but it is still slow. I wonder if I should move all the vm off the other two data stores and delete, and rescan the esxi for storage and back as data 1 and 2 stores. I have esxi 4.0 not improved update2. and there an esxi license and there 6 installation of drives western digital black 1 TB in raid1 3 - then I have every configuration of raid as a logical drive which is then turned into a data store.

    I don't know if the downturn is the hardware or a virtual machine is pulling them down - I'll start out them one by one to test tonight, but the advice or opinions are welcome.

    I don't know what your storage looks like initially but I would recommend HAVE TO go with update 2 - we had all sorts of problems with particular storage when you use storage VSA as the left hand.  Update 2 provided some great improvements to the vmkernel regarding VMFS.

    You can also publish newspapers vmkernel of any of the host in question and we can take a loo at it.

    Seriously, update your esx/esxi servers is always a good practice when you have weird problems.

    See you soon,.

  • Reference Dell 5558, 8 beebing on startup, no black screen and works with the beebing

    Hello

    I have a problem with my Dell insipiron r15 5558, I bought it 3 months ago. But last month my laptop beep 8 times at startup. When this happens, I usually only the power out of my laptop because of the distracting noise and turn it back on. Once I powered on / off power for 3 - 4 times it don't beep plus one works very well. Anyone know what could be the problem? I ran a Test LCD and an analysis of Pre-boot system, it was running fine without any problem, I used my warranty and sent the labtop to dell here the last 2 weeks, they sent and didn't tell that it is no problem with my laptop, but it is still beebing 8 times by clicking on the power on

    BTW. I'm on Windows 10 pro 64-bit

    Hello

    8 attention beep is usually to do with the problems of LCD, as you already know.   If diagnostics are passing and the system has been returned to the warehouse for the evaluation, the only thing I think it could be is a connecting cable of the LCD screen.  You said sometimes works very well after starting several times, then maybe it's the cable.

    Have you tried to hold the screen in different positions when it turn on?   Just to see if guidance works better and maybe the cable is a better connection.  You can check if the cable is loose yourself.  Here is a link to the online manual for the Inspiron 15r 5558.  You can use it to see how a screen is normally replaced, but instead to replace it you would just check the connection of the cable to make sure it's tight.  NOTE: Make sure you follow the safety instructions and information in the section "before you begin".

    Let us know if you find a loose fitting and if the adjustment of the angle of the screen change anything when you try to turn on the system.  I hope it's something as simple as a bad connection and you can correct it.  If the ringing continues I recommend to contact Dell support again and have them send it back for repair, unfortunately.
