RAID 1 or RAID 10 for Production, I'm stuck

Hello

Here's the situation.

In the production server, we have RAID-1 for the ESXi, and for the storage of the actual VMS I am debating between RAID-1 or RAID-10.

I have Six WD Eneterprise drives of 1 TB - 7200 RPM, I'll be puttin on 8-10vms on this all VMs are running standard Windows 2008 R2 64-bit running SQL on each of them (not heavy at all) each vm will have 3-5user.

I want performance, but I really want is the security of the data. What happens if my RAID-10 bad crashes, disk recovery is going to be hard on a RAID-10 compared to RAID-1 crash. I can do an easier than a RAID 10 RAID-1 recovery.

My VMs are 127 GB a piece (vms total 8)

I was going to put 4 - VMs on each RAID-1 array

Matrix RAID-1 #1: 4 - vms (127 GB)

Matrix RAID-1 #2: 4 - vms (127 GB)

Matrix RAID-1 #3: data misc

or a RAID array-10 and all 8 - VMs?

What is your vision on what everyone, RAID-1 have more security on data incase the raid is dismandeled or bitrot, etc... or RAID-10?

Who will be the best choice for production with safety first and 2nd Performance.

Thank you

Welcome to the community.

In some cases RAID10 is more reliable then RAID1... But yes... is more complicated.

If you need reliable max the best RAID6 is but also the worst (in general) on I/O of Scripture.

  • RAID 0 for a RAID configuration not "this computer's hardware may not supported booting from this drive.

    I want to install a new HARD drive in a tower of the mine to a friend. It was initially created as a RAID 0 configuration with two 160 GB HDD. The replacement is a single 1 TB of HARD drive. I get the message "this computer's hardware may not supported booting to this disk.» Am I missing an approach from a RAID 0 for a RAID configuration, no?

    Hi RegularPencils,

    I suggest that you check in the basic input/output system (BIOS), if you find an option to disable the RAID. If you find, disable the RAID and try to install Windows vista, check if it helps.

    Important: Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

    Error message when you try to install Windows Vista on a computer that contains multiple RAW hard disks: "Windows cannot find a system volume that meets its criteria for installation.

  • Dell PE 2850 Raid config for ESXi4

    We have a few spare Dell PE 2850 and will be installing ESXi 4. I was wondering what would be the best config. RAID 1 for the 2 first discs and then raid 5 for the rest of the raid just 5 all the way together.

    Thank you

    Out of these two options, it is greatly preferable to use one large set.

    However, performance will be better with a RAID-10 set.  Anyway, the controller must have a pile of work on the PERC.

    Please give points for any helpful answer.

    You are missing a lot of the associations. You need to reinstall your programs from the CD or the installable executables. I'm sorry that you do not have your Office CD-ROM, but you cannot reinstall Office without it. You can:

    When Flash Builder, I configure my project for the mode of Production, he asks me a RIM certificate that must be registered (and then need a CSI file?). Where can I find this file?

    Thank you

    Signature of application information has not yet been published.  You can submit your application unsigned.  In addition, in FB4, in the Properties window of the project, under the Flex compiler, you can add

    -debug = false

    to compile without debugging information.

    Otherwise, .bar file creation is done in a regular compilation with BB CLI package.

    This sounds like your problem? - http://forums.whatthetech.com/index.php?showtopic=104537&hl=This+action+only+valid+products+that+currently+installed+Windows

    It lists the reg keys his looking, then you might check to see if you put them before doing anything.

    Back up your registry and set a restore point before taking any action - assuming that is your problem.

    Also, if you download and run the file, AV check it before running it - just in case.

    NOTE: the above was found by google, I have not tried that I have not had the error. I can't say if it works or not.


    PS - Also, FYI, while the research I found this http://support.microsoft.com/kb/893048 , but it seems specific to XP - SP2. Don't know if there is an equivalent W7.

  • Want to switch from Windows to Mac OS for Production Premium CS5.5

    Want to switch from Windows to Mac OS for Production Premium CS5.5, get a serial number error, assumes that I have a serial number of Windows and need a serial number for Mac OS?

    Not possible... Windows programs do not work on a Mac, and vice versa... and a serial number of Windows is ONLY for Windows program

    Your version is also too old for Adobe to provide a platform swap

    You may be able to use your current version to get a special price if you buy the CS6 for Mac

    Link to buy the CS6 via phone http://www.adobe.com/products/cs6.html

    From what I've learned by an employee, most recent Mac 10.7 must subscribe to the cloud instead of buy CS6

    Please report back with your operating system if you are able to buy CS6

    Hello

    did you purchase your product of these companies like Amazon? If Yes, this isn't a serial number, only a code with which you can request a serial number from Adobe. Please take a look at http://helpx.adobe.com/x-productkb/global/find-serial-number.html. (Start here: How did you purchase your product?)

    The next part, so I don't see at the very least, ceased to exist on my Adobe website, everything happens in the link above. I leave as an info yet, he could still fit for you. For this purpose, please click your way through your Adobe Store and find the button "get serial number". Fill in the form and after awhile, you will get the real serial number.

  • Can CC subscribers install LR CC for evaluation and keep LR5.7 for production?

    I would evaluate LR CC, but have plugins that are not compatible with it. Therefore, I want to keep LR5.7 for production use. Is this possible?

    Yes, it will convert LR 6 (making a copy) your catalog and you can then edit in the new version.  You must take caution, for example in the operations that modify your real images (like metadata writing or animated images).

    The safest thing would be to NOT convert your catalog but rather to build a workspace hand full of images and catalogue which is available, but it is certainly possible to test LR6 in place if you are careful and aware of what operations you perform.

    Note You can run 5.7.1 LR and LR 6 (aka CC) compared to the creative clouds at the same time as well - you can still go back and install older versions of the CC app.
