Selecting a boot drive for Hyper-V 2012 server - is a boot drive performance important?

I'm setting up a new Hyper-V 2012 server dedicated to virtualization and I'm trying to determine the best choice for the boot drive.
I have 2x250gb SSD drives i'm considering for storage pools for VM's
I have an old 80GB SATA drive
I'm wondering how important the primary boot drive is in a Win 2012 Hyper-V setup. I can partition one of the SSD's to provide a boot partition, or I can just dedicate the 80GB SATA.
What do you think would be a better choice?
Edit: A more precise question, why not partition the SSD for boot? Is there any benefit for separating the disks for boot vs just the partition?
Thanks,
Deco

Hello,
I hope you are having a great day!
What resources are available to you? If you have hardware RAID, it would be best to configure the SSD drives for RAID 1 (mirrored) and run everything from that. This will provide you fault tolerance in the case of a drive failure.
If hardware RAID is not available to you, then definitely use the 80GB SATA drive as the OS Boot Drive, without a hardware RAID for the OS disks you will have a single point of failure no matter what disks you use. Yes with SATA drive the system will boot
up slower :-( , but that is about the only negative.
This will also enable you to leave the SSD's as RAW un-formatted disks which can then be configured in a Storage Pool with mirroring if you wish and then have the VHD's reside there.
Absolutely, dedicate the SSD's for the placement of the Virtual Machines Config and Vhd/Vhdx Files.
For absolute best performance results use VHDX Fixed disks for maximum performance.
Dynamically expanding VHDX will have a minor almost unnoticeable performance hit (depending on the purpose of the VM) and help ensure that the amount of hard disk space the VHDX file is occupying is kept to a minimum. An example of degradation in performance
would become noticeable if for instance, the VM is being used as a file repository and users are constantly uploading files.
The bottom line is, if you don't have hardware RAID for the OS you always have a single point of failure, so hope for the best and keep great backups.

  • Can I use my late 2006 mac mini as an external drive for my late 2012 mac mini?

    I have a (late 2006) Mac mini that I would like to use as an external drive for my (late 2012) Mac mini.  Is this possible and can anyone suggest what cables would be needed.  I am aware that the ports are very different i.e firewire and thunderbolt.  Thanks in advance!

    - You can boo the old Mac in Targe Disk Mode and connect the two via FireWire (FW) You will need a FW 400 to FW 800 cable or a FW 800 or FW 400 cable and appropriate adopters
    How to use and troubleshoot FireWire target disk mode - Apple Support
    - Use the old Mac normally and setup Disk Sharing and access the old Mac via the network. The old Mac's disk will show up  under Devices on the new Mac. One you set up the old Mac yo do not need mouse or keyboard or monitor. You can also setup Screen sharing and actually use the old Mac from the new Mac.
    - Remove the HD from the old Mac and place it in an external USB enclosure of dock and connect it to the new Mac

    I would also look strongly at no antivirus as well, but if you do, here are the recommended exclusions and possible issues with Anti-Virus to look out for.
    Look for the Hyper-V section:
    http://social.technet.microsoft.com/wiki/contents/articles/953.microsoft-anti-virus-exclusion-list.aspx
    Big things to stay away from from a VM level too:
    1. Do not have a set time when all VMs will kick off a scheduled full disk scan.  This can create an I/O storm on your hosts as well as saturate the CPUs as well.   Look for products or settings that allow for randomization of full disk scans on
    the VMs or do not do full disk scans and only keep the real time scanners active on the VMs for incoming writes.
    2.  Watch for Antivirus products that update all the VMs at the same time.  Again, sometimes you can randomize or exclude a scheduled full disk scan, but sometimes an automated update that kicks off say at 12am can then automatically kick off a
    mini scan.   This can also create disk I/O and CPU storms.
    The problem that still exists with many Antivirus products today is that they try to scan as fast as they can and then get out of the way.  This works ok for endpoint desktops or laptops, but when you have 50 or more VMs on a host all ramping up trying
    to get done as quick as they can, then this can cause some issues.

  • 2008R2 Virtual machine shutting down unexpected on Hyper-V 2012 server

    I have a problem where one of my 2008 R2 virtual servers are shutting down unexpected every Friday at more or less the same time. This has happen 2 Fridays in a row now and the time is 13:01:30 and 13:01:10. I did some investigation on the event viewer and
    it tells me the following: (Error) The previous system shutdown at 01:01:10 PM on ‎2014/‎08/‎01 was unexpected.  Event ID: 6008 which I have goggled and did not find much on this ID?    I also found the following event more or less the same
    time as the first one: (Critical) The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Event ID: 41.  In most posts it looks like if it could
    be hardware related? But how do I justify this on a virtual machine?
    Some Infrastructure background: It is a 2008 R2 virtual server running on 2012 Hyper-V, 2012 server. SCVMM is not configured so all administration is done through Hyper-V manager. The virtual machine is backup up by Symantec backup exec and the Full backup
    only start at 23:00pm night time. No scheduled shut-downs are configured and all servers are running on UPS power, the virtual server are also configured to boot up automatically after any failure. But in this case the server is completely shut-down and I
    have to manually start the server up again.
    I hope there are somebody who can give some guidance on my problem?

    Hi Sam
    Thanks for the reply!
    Yes, all disk space is on the host, I have 2 hosts running Hyper V each with their own set of virtual servers, I am planning a cluster in the near future, but for now all disk space for all virtual server are on the host, there is more than enough disk space
    left on all drives. Please below output from command, I only posted first few lines as there are to many lines.

  • How do I turn off Hyper-V 2012 server sleep mode?

    Just installed Hyper-V 2012 server on a HP ML360 G8. Also installed Corefig 1.1.1. It seems after about 10 minutes if idle time the monitor goes black and the unit goes into sleep or hibernation.  I have used powercfg to set it to the High Performance
    power scheme and set screensaver to none in Corefig. 
    When the monitor goes black, if I move the mouse the sconfig screen, corefig, etc windows do not show until I run the mouse over them. Even then the windows do not 'repaint' until I run the mouse over the whole window or make some kind of key stroke in each
    window.
    Worried what this will do to my VMs once I start building them and would like to see the screen at all times.  This is the first 2012 box and I have never had this issue with any of the Core 2008 products.
    Thanks

    Hi,
    “I can't locate the GUI you show, it's Hyper-V 2012 Server,so i can't edit the settings. 
    Sems like it may be the monitor itself is going to sleep”
    The other possible is you don’t have the administrator rights, or your server has got the Power Management, after you configuration the power option, the GPO refresh then
    the old configuration be covered. Please refer the following article to confirm that:

  • Where can I get the driver for my HP DE8A4L external USB CD/DVD drive?

    Where can I get the driver for my HP DE8A4L external USB CD/DVD drive? 
    On the label it says, Model HSTNN-PD06-91
    and
    HP PN: 518819-001 Rev.B
    I've had my Mini 110-1000 running our music system for a couple of years, no complaints.  When I wanted a CD/DVD drive, I purchased a DE8A4L external USB drive directly from HP.  It didn't come with a driver disc.  When I plug it in, the USB subsystem does not enable it.  Device Manager shows a yellow exclamation point, saying, "Windows cannot load the device driver for this hardware..."   It is running Windows XP Home Edition SP3.
    What gives with this device?

    Following up on tactic 2) above, I upgraded the BIOS from version F07 to the latest version available on the HP download site, version F19.  This went well, but unfortunately the system still does not recognize the device.
    When I try to Device Manager, and select the DE8A4L DVD device, and try "search for a device driver", it says it cannot find a better match for the driver already installed.
    This Mini 110-1000 only came with 1 Gb RAM, and Windows XP Home.   Is one of these a critical limitation for running an external USB DVD drive?

  • PLEASE HELP me select new internal hard drive for Macbook Pro 2012 (non-retina)

    Good afternoon.
    I just bought a Macbook Pro 2012 (non-retina) 15 inch from a friend.  I think it is running Mountain Lion (has not been upgraded to Mavericks yet), and has iLife on it.  It came with the stock 500 gb 5400 rpm internal hard drive.  At home, I only have the Snow Leopard OS installation Cds and a copy of iLife 2011 installation Cds.  I am going to buy 16 gb of RAM from Other World Computing to install.
    I want to replace the hard drive with a 1 tb hard drive, preferably something that is $100 or less.
    I talked to Other World Computing (OWC) and looked at the Data Doubler Option to replace the optical drive with a Solid State drive, but decided that for now I want to keep the optical drive inside the computer for portability issues.
    I know that Solid State drives are better, but they are still too small, and I want the ease and portability of a 1 tb size INSIDE my computer.
    Initially I was going to order this from Other World Computing: 1.0TB 2.5" HGST Travelstar 7K1000 7200RPM SATA 6Gb/s 9.5mm Notebook Drive 32MB Cache. *'New' Factory Replacement with 2+ Year HGST Warranty*    As of April 4, 2014 it's on sale for $79
    But then I started reading some of the discussions online and thought maybe I should get a hybrid solid state drive?
    I saw on Amazon the Seagate 1TB Solid State Hybrid Drive SATA 6Gbps 64MB Cache 2.5-Inch ST1000LM014  It's on sale for $94.
    But according to some reviews, this Seagate has a platter that is only 5400rpm, unlike the previous Seagate Momentum that has a platter speed of 7200rpm.
    How reliable are the Seagate, versus a Toshiba or Western Digital or Hitachi or something else?
    Here are my questions about replacing the hard drive:
    1.  Is a hybrid solid state drive going to need some kind of special formatting after I put it into the macbook so that I can put the operating system on it?
    2.  Is a "normal" platter hard drive more reliable than a hybrid solid state drive?
    3.  Is there any additional driver or special software that I have to install for a hybrid solid state drive?
    4.  Currently there is no personal data stored on the computer.  Can I just put the new hard drive in, and then insert the snow leopard install cd?
    5.  If I install snow leopard, can I just go to the App store and get the free upgrade to Mavericks?
    6.  If I want to do the "Data Doubler" option in the future and add a normal Solid State drive into my computer, will it have trouble interacting with the 1 tb hybrid solid state drive?
    I would love to get some recommendations about the smartest option to upgrade my hard drive with something that will be fast (I edit lots of photos) and large (1 tb) that isn't going to cost too much.  I don't know much about the different brands or options (and there are so many listed in tons of online reviews), that I got really overwhelmed and confused by the info out there.
    I would really appreciate any help and advice.  I've never switched out a hard drive before.
    PLEASE HELP !!!  Thanks!
    Here is the "About this Mac" Info:
    Macbook Pro 15-in Mid 2012
    Model Identifier: MacBookPro9,1
    Processor: 2.3 GHz Intel Core i7
    Memory: 4 GB 1600 MHz DDR3
    Software: OS x 10.8.5
    Storage (Hard drive): APPLE HDD ST500LM012 Media, Rotational, SATA, GPT (GUID Partition Table)

    1.  Is a hybrid solid state drive going to need some kind of special formatting after I put it into the macbook so that I can put the operating system on it?
    The boot drive, regardless of what it is, needs to be formatted as Mac OS Extended (Journaled).  This is standard with OS X.
    2.  Is a "normal" platter hard drive more reliable than a hybrid solid state drive?
    There are arguments pro and con.  Bottom line, SSD's and hybrid drives are still quite expensive per GB than standard hard drives.  If you have the bucks and are a speed demon, go ahead.   I have better use for my money.   Standard hard drives are mechanical and may wear out over time.  But even though SSDs are not mechancial, they can still go bad and ultimately they even have a limit to their write capacity.  The jury is still out on this debate.
    3.  Is there any additional driver or special software that I have to install for a hybrid solid state drive?
    No
    4.  Currently there is no personal data stored on the computer.  Can I just put the new hard drive in, and then insert the snow leopard install cd?
    You can physically put the hard drive in but probably not install Snow Leopard on this MBP.
    The mid-2012 MacBookPro9,1 models came with Lion 10.7.3 (11D2097) preinstalled.   It is very unlikely you would be able to install Snow Leopard on it.  Historically you cannot install a version of OS X that is earlier than the version that came with your Mac (even if you replace the hard drive).
    5.  If I install snow leopard, can I just go to the App store and get the free upgrade to Mavericks?
    Not via Snow Leopard on this MBP.  See my response to #4.
    6.  If I want to do the "Data Doubler" option in the future and add a normal Solid State drive into my computer, will it have trouble interacting with the 1 tb hybrid solid state drive?
    No.  They are completely independent of each other; they are just independent storage units (drives) and their RAM does not interact.

  • Current best practice for Time service settings for Hyper-V 2012 R2 Host and guest OS's

    I am trying to find out what the current best practice is for Time service settings in a Hyper-V 2012 environment. I find conflicting information. Can anyone point me in the right direction. I have found some different sources (links below) but again the
    are not consistent. Thanks
    http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/11/19/time-synchronization-in-hyper-v.aspx
    http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(v=ws.10).aspx
    http://social.technet.microsoft.com/wiki/contents/articles/12709.time-services-for-a-domain-controller-on-hyper-v.aspx

    From the first link provided by Brian, it does state that the time service should be off, but then the update changes that statement.  Still best to rely on the first link in the OP - it was written by the guy that has been responsible for much of what
    gets coded into Hyper-V, starting from before there ever was a Hyper-V.  I'd say that's a pretty reliable source. 
    Time service
    For virtual machines that are configured as domain controllers, it is recommended that you disable time synchronization between the host system and guest operating system acting as a domain controller. This enables your guest domain controller to synchronize
    time from the domain hierarchy.
    To disable the Hyper-V time synchronization provider, shut down the VM and clear the Time synchronization check box under Integration Services.
    Note
    This guidance has been recently updated to reflect the current recommendation to synchronize time for the guest domain controller from only the domain hierarchy, rather than the previous recommendation to partially disable time synchronization between the
    host system and guest domain controller.

    Hello jayparks41
    There are a few things to try and the article below can walk you through them before trying to hunt down a Snow Leopard install disk. I will say that it may come down to reinstall Snow Leopard but also before any troubleshooting, make sure to have a safe copy of your data.

  • Hyper-V 2012 R2 & Windows 8.1 VMs performance metrics using WMI query

    Hi,
    I used the following query to fetch the Disk utilization for Hyper-V VMs (non v2 hosts) using its host credential "select ReadBytesPersec,WriteBytesPersec,ReadCount,WriteCount from Win32_PerfRawData_StorageStats_HyperVVirtualStorageDevice" but
    for the V2 (Windows 8.1 & Windows 2012 R2) this query is not working this is throwing Invalid class using the namespace "root\cimv2".
    Please let me know the exact WMI class for the Disk utilization for V2 hosts VMs.
    Regards
    Raamesh Keerthi N J

    Hi,
    In my lab server 2012R2 , I run this command :
    get-cimclass | Where-Object { $_.cimclassname -like "*hypervvirtualstoragedevice" } | fl cimclassname
    I got two classes :
    Win32_PerfFormattedData_Counters_HyperVVirtualStorageDevice
    Win32_PerfRawData_Counters_HyperVVirtualStorageDevice
    You can try them
    Best Regards

  • Need Driver for MAT**bleep**A DVD--RAM UJ-860 Drive

    Searched everywhere for a Driver for the above drive.  Drive has  a exclamation mark shown in the Device Manager display.  Not sure how the driver got deleted or what have you. Please supply whateever information you might have.
    Thank you,
    GENO

    hardware or ultrabay problem is your affliction, the included ATAPI Win32 drivers are used to kick start CDROMS for yeasrs now and ever since Adaptec lost the ASPI wars in 2002 (too long of a topic to mention now)
    Removing the ATAPi drives is a try but those are proteced with WfP so if they were corrupted, they would've been autmaotically repalced and you would've just gottnen a pop up to have a nice day.
    elminaite the ulgra bay or that CD asyour issue, did that drive deteoirate or belly up overnight?
    Can it still boot CD's from a cold start ? Can it boot a BARtPE or other type of CD based OS and seeminlgy run w/o hciciupting that one ?
    If that ultrabay slot, and that CD works in other opoerating sytems...then you could have an insidiuous but curable problem with Windows Drive FilterLoad order...as haoky as that sounds it is the way Win32 allocates sub funcitons such as CD writitng, litescriinb and DVD burning to a drvies hardware.
    IF you renecently isntalled any type of CD burner or speical CD audio software it could be the culprit, don't rule out Roxio Media Manager that RiM upjams into their Blackberry Desktop software for their phones, the horror stories of how people are forcded to reinsatll their entire copy of Windows because Roxio just fuugugueued up their CD drive after hotsyinght their address book of fat friends into their brand new skinny blackberry are commonplace at the annoyance web sites. Sadly, there are documnted instances where Roxio Media Manger jammed into the blackberry deskotpo can even kill of the reigerestred vresions ofr their preexisintg Roxio burner software !!
    If that sounds like soemthing that you may have done, then download a copy of ImgBurn, aside from being more CD burner than one person can e3ver user, it also has a verigthtt sreagaetrieforward and clean mneu to reoder qnd rmeove thaose drive filters and could be a two minute tool to get your life back in order.
    Don't just sit there, take a second and use the Kudo's button to compliment the people who help you.

  • HT201250 How can I revert to my internal drive for time machine backups after using an external drive?

    Hi. I've been using an external drive for time machine back ups and decided to revert to my internal drive, but it isn't available in the time machine options. The only available option is to set up a time capsule, which I don't own.
    Is it because not enough space is available on my internal drive (approx 50GB)?
    Thanks!

    50 Gb free on your internal drive is relly very low and of course not enought for a any kind of backup.
    How big is your internal HD ?  If you have left only 50 GB free it is probably 90% full. Let's imagine you have a 500 Gb. This means 450 Gb data and 50 Gb free.  How can you backup 450 into 50 ?
    Second point. The backup on your internal HD is a nonsense evenif it is big enough. If it stops working you will have no bakup.
    Do you have an iMac or a portable ?
    The portable automatic uses the internal HD if the external is not connected, but this is intended for a short time.

  • Driver for 40Y8686 CD-RW/DVD-ROM Combo II Drive

    For the life of me, I cannot find this driver for download from the web site.  Any pointers would be GREATLY appreciated!

    My Dvd drive cames without and AC Power adapter, it suppose that only needs one USB 2.0 port (no external power adapter is required for read/write operations when it is connected to a single USB 2.0 port on ThinkPad notebooks, the drive can be powered directly through the USB cable whe it´s connected to a USB 2.0 port, and optional 5V AC adapter can be used fir USB 1.0 or 1.1). My notebook its a lenovo x201, its compatible?. I need to buy and AC Power adapter?
    Thank you very much for your help.
