Can you have multiple databases on the same LUN in Exchange 2010?

I'm sure you can but is it possible with exchange 2010 to have multiple databases on the same LUN.  We currently have 8 DB's all writing to their own DB drive and separate log drive so 16 drives in total.  I need to spin a new DB up this week and
wanted to double check this is possible.  I've looked online and cant find anything that I've seen before that says this is possible.
Thanks.

Hi,
Yes, multiple databases could be placed on the same LUN, but it's not recommended.
If you have 2 drives fail at the same time (it happens more than you think), then losing 100% of your DBs is a lot worse than losing one of them or some of them depending on where the failures are.
Here is a similar thread for your reference:

Hope this helps!

  • HT1766 can you have multiple iPhones in the same iTunes account without overwriting each phones content?

    Can you have multiple iPhones in the same iTunes account without overwriting each phones content?

    Hi sandexpress,
    As Ocean20 indicates, you want to make sure that you have automatic syncing turned off. In iTunes Preferences under Devices, make sure you have "Prevent iPods, iPhones, and iPads from syncing automatically" checked. Then connect each iPhone, and make sure that "Manually Manage Music and Videos" is checked on the Info page for each of them. Then go into each page for each device, and select what you want to sync to that particular device. (you would do this one device at a time - complete the steps for one of the phones, then connect the next one and do the same thing).
    With this kind of setup, you can modify what will sync at any given time for a particular device once you have connected it to iTunes, but before you click on the Sync button at the bottom of the screen. If you want to change some sync options on a particular device, you would just go into the page you wanted to change (Music, Photos, Apps, etc.), make your changes, and then Sync.
    If you do not have any changes, you can just hook up the phone and click on Sync.
    Hope this helps.

  • Can you have multiple accounts on the same ipad2?

    Can my wife and I share the same iPad using two different accounts? If so, how?

    If you want differing accounts (like on a PC where you login to different user accounts) with different settings (like background image, icon settings per page, etc,) per account, then no.

  • HT1311 can you see which device bought something on iTunes where you have multiple devices on the same iTunes account?

    is there any way to find out which device dowloaded apps when you have multiple devices using the same itunes account? 

    The purchase information does not include the device used, but does include the Apple ID used for the purchase.
    Apps downloaded on one device with the same Apple ID can be downloaded on another device with that Apple ID.

  • Can we have multiple Podcasts with the same Mac Account?

    Hi all,
    Can we have multiple Podcasts with the same Mac Account?
    For example, I have a single .MAC account and create a website with multiple Podcast pages...or within iWeb I create multiple sites, and each has a podcast.
    Is there a problem?
    Thks

    Its not possible for the same development object. Only 1 person can access an object at a time and if mutiple users modify an object new TASKs are created under the same TRANSPORT.
    Only after releasing the tr you can create a new tr on the same object.

  • Can you opening multiple albums at the same time in Photo (not iPhoto)?

    When converting the iPhoto library to Photo most of the albums that were in place in iPhoto converted to albums in Photo . . . .but not all. Some were retained as events mainly those that were folders within an album. In order to move them to the right album I would like to have multiple albums open at the same time (side by side) so that I can make sure not to duplicate photos or move them to the wrong spot.
    I cant see how to do this, it seems that I can need to open one album and check phots and then close to look within and other and rely on memory. There must be a more efficient and accurate way to do this?

    All of the events in iPhoto were converted to albums and are located in the Folder titled iPhoto Event in the sidebar of Photos. 
    You can't open multiple albums at the same time.  You can create a smart album that will do essentially the same thing with the following criteria:
    Album is "A"
    Album is "B".
    The smart album will display all of the photos in those two albums.

  • Can you avoid multiple clips of the same media in a project

    We have 2 suites and we sometimes work together on a common project utilising the same media.
    If I want to use a sequence from the other suite I can easily import it.
    The problem:  it creates another folder with clips that only belong to the imported sequence.
    The end result after a few imported sequences is that my final timeline has instances in it that
    are from clips belonging to several different folders or bins even though the media is the same.
    In summary... is there a way you can avoid having multiple clips of the same media in a project.
    Makes for a very messy project when you have finished.
    You've got multiple clips with the same name scattered everywhere.
    Cheers

    Not yet.
    I'm kind of hoping this type of media management will be vastly improved in CS6, whose main new 'feature' reeeeeally needs to be outstanding network collaboration with other editors working on the same project.

  • Can we have multiple policies for the same gateway?

    Hi all,
    Is there a way in which we can have multiple policies for the default gateway?
    When I try adding a new gateway (which is not mentioned in the installer.properties file) and have policies, there is a 404 error.
    When I add another service to the same gateway, I get an error - that the service could not be added to default policy.
    Help me please...
    My need is as follows
    Want to have multiple policies, so that each of the web-service can be attached to same. The relation needs to be one-to-many. One policy can have multiple web-services.

  • Can you open multiple windows of the same Keynote presentation?

    Like you can in PPT, where you can go Window > New Window, and see more than one slide at once of the same presentation in the large view. If there is any way to view more than one slide at time, in the large view, please let me know.
    I know about Light Table, and that's useful but I really want to be able to open multiple instances of the same presentation like I could in ppt.

    Thanks, I will. It seems like such an obvious thing, yet I could not find anyone referencing it anywhere. I thought I was the only one who used ppt (or now keynote) that way. Otherwise it is awesome, so much better than PPT.

  • Can we have multiple IE in the same machine to access IC Webclient ?

    Dear expert,
    I have a question here. Can we access IC Webclient if our computer have multiple IE ( E.g IE 6 & IE 7 ). Currently the client computer have multiple IEs in the computer by using Tredosoft product. The environment of the system is as below :
    Server environment :
    1. Windows 2003 server Enterprise Edition
    2. SAP Netweaver 2004s SPS9
    3. SAP CRM 5.0 (ABAP & Java stack)
    4. SAP Enterprise Portal 7.0
    Client PC :
    1. Windows XP Profesional SP2
    2. Java Runtime Environment 1.4.X
    Your help is much appreciated

    Hi Ku Izrul Hadi Ku Hilmy ,
    For the Webclient to run you just need a browser. It will work on IE06/07 . Just the thin client should be properly configured. As far as the requirements put down by you is concerned I dont think so there should be any problem for the webclient to run from the client side.
    Reward useful answers,
    Regards,
    Shrita Sharma.

  • Can you have two services on the same IP within the CFE?

    Hi,
    I am testing AccAD and have come across a situation where we have two HTTP SAP systems, one portal and one SRM, that have the same destination host, ie http://testapp. But a end user will access each system via the URL's http://testapp:9010 and http://testapp:9015.
    I can get AccAD to connect to both different apps by changing the DNS but inside one of the apps it will call the other using http://testapp:9010. so unless I change the internal config one app can not call the other.
    So what I would like AccAD to do is call app1 via http://testapp:9015 and the other via http://testapp:9010 where defined in AccAD the hostname testapp is the same IP address.
    Any clues and sorry if the problem explaination is confusing?
    Regards
    Brian Lane

    Hi Brian,
    I checked your question with the development team, and here's the response:
    If you define 2 service types under the same server then you will have delivered services on the same IP address.
    The only thing that you need to consider is that the 2 service types will have the different ports.
    Define one service type with port 9010 and another one with 9015.
    After this step, as usual, please add both service types to the server and define remote offices.
    On the CFE you can then do: netstat -ntl
    You will see the same IP address listening to 2 different ports.
    Hope this helps, best regards
