The merit of multiples of VHDs

When you set up a new virtual machine is no basis to the addition of several virtual hard drives (for example one for the files of the OS and the other for the application/data files) instead of creating a large virtual hard drive?  I always physical servers for installation with a set of disks for files of the OS and another set of discs with data files for reasons of redundancy and paging IO.  With discs hard virtual these advantages still apply?

Here are some reasons I used disks separated instead of partitions or drives big one

  • Management

    • Easier to grow records

      • If all partitions are on the same disk, it is more difficult to add space.

        • Windows 2008 supports this on the fly for ESX 4.x (and probably for other operating systems)
    • If your data store fills (it happens when you least expect it. usually caused by another admin while you were on vacation) it is easier and faster to move the small disks for out you of the mess faster
  • Performance
    • You can move your highest workloads to different LUN IO or other type of storage iSCSI/NFS/fiber and leave your OS partitions on different types of storage
  • Backup
    • You might want to just the OS partition or partition to backup data
    • You can only restore the operating system or restore data partition
    • You might want to only replicate the replication data partition
  • Architecture
    • To get the best use and performance absolute dedup NFS and data as a NetApp, there are some suggestions that some types of data (Exchange/Application/OS file put there own volumes) be on the Netapp. http://media.NetApp.com/documents/tr-3428.PDF

Reason not to:

  • Disaster:

If for any reason your vmx file is damaged or is missing. It can find all the disks that make up your virtual machines difficult and understand what order they must go hand in hand. (if you have a backup of the vmx file and virtual machines this is not a problem)

  • MRS. Usually LUNS are replicated for RS, but I have not implemented SRM and this may have changed since I had not really looked at him for everything. If you distribute you on different LUNS vmdk files then it may not work for MRS.
  • Space if thick you are supplying, then you would probably better use out of space in a more vmdk file and then smaller. If you Thin provision is not really much of a factor.

In general I VMs to create an operating system partition and a partition of data (aligned) on the same data store. If there is reason to move them, I do. It is above all the simplicity of the expansion of the virtual machine storage. If several drives are necessary (SQL, Temp/newspapers/backup/data) I have just create individual records for each. Even if you have multiple disks, you can manage them all VM level.

There is very little downside to multiple discs

Hope that helps

  • Why the rejection of multiple photos doesn't work anymore when you change pictures?

    Why the rejection of multiple photos doesn't work anymore when you change pictures? Does anyone else have this problem? It works on my other Mac but just stop working on my computer laptop pro, I have the latest OS and it worked until a few weeks ago. Thanks for any help!

    Selection of several photos at once enter "9" to reject all still works them for me in Aperture 3.6 on El Capitan.

    Have you tested, if the problem occurs only in an Aperture library or libraries opening?

    Create a new Aperture library to test and see rejection, so it works.

    If it does not work in a new library either, I got trash Aperture preferences.

    In preferences file is now in the container folder in the user's library.

    Try this:

    • Leave the opening runs.
    • Then open your user library and delete the folder complete ~/Library/Containers/com.apple.Aperture/
    • and the ~/Library/Preferences/com.apple.Aperture.plist file

    Your user library can still be hidden. To reveal the hidden user library:

    • Bring the Finder to the front by clicking on the desktop or the Finder icon in the Dock.
    • Select your folder user/home (with the House icon in the side bar of the Finder)
    • With this window in the Finder in the front window, press the ⌘J key combination to bring up the display options.
    • In the view options panel allow you to "show the library folder. That will make your visible user library folder in your folder.
    • Open your folder, then the library folder, then the containers.
    • Move the entire folder ~/Library/Containers/com.apple.Aperture on your desktop. Move the entire folder, not just the content.
    • Delete ~/Library/Preferences/com.apple.Aperture.plist as well.

    Now, restart the Mac, start Aperture and try see your book.  If all goes well, delete the folder on the desktop.

  • I want to activate the outputs audio multiples to be active, so I don't have to wear my helmet all the time, or need to disconnect anything to the speakers.

    Pretty simple question really. I want to activate the outputs audio multiples to be active, so I don't have to wear my helmet all the time, or need to disconnect anything to the speakers. I checked the 'sound' thing in the Control Panel, but the enable option is not letting actually work. So if I want friends to hear my video games or something else, I turn on my speakers and they can hear it now.

    Thank you.

    Windows does not support this. This is handled by the device drivers or hardware - if they don't support the outputs multiple, you can try the search for an alternative solution.

  • BVI Interface inaccessible since the addition of multiple SSID

    Announcement to the community for the first time.

    I have a simple HomeLAN which consists of a Cisco router for series 800-> switch PoE Cisco3560-> Cisco Aironet 1131AG Access Point.

    Everything works well for a while in which I had a simple port to "change the access mode" configured on the switch facing the AP and one SSID on the access point that is configured in stand-alone mode (without controller).

    My provider has enabled IPv6 on my broadband connection and I started to reconfigure my installation this afternoon to allow this.

    I decided to run only a bunk Dual LAN and a separate native IPv6 only test LAN for proof of concept.

    With this in mind, I changed the switch port to the access point to a "mode trunk switch' using simple dot1q encapsulation. I have also consulted the post helps very https://rscciew.wordpress.com/2014/05/24/multiple-ssid-configurations-on... after finding in this community post on the topic of multiple SSID https://supportforums.cisco.com/discussion/10899511/how-broadcast-2-ssid...

    I have now two SSID broadcasting (we will call double stack and ipv6 only for the sake of the argument). The SSID double stack uses VLAN 2 and 1 bridge, while the SSID only ipv6 uses 6 VLAN and bridge 6.

    I must stress at this point that my router (where I want to layer 3 for the two LANs gateways) I have DHCP, DHCPv6 and SLAAC configured on relevant VLANs.

    I seem to be the 2 VLAN trunking of properly and I can see the SSID broadcast in my house. I can connect to the SSID (authenticate and form an association as seen in 'show the dot11 association'), but I don't get an IPv4 address or IPv6 assigned to all clients (I tried Mac OS x, iOS, Android, and Windows phone). Furthermore, I can't ping the IP bvi1 of the AP - that is the element that is annoying me more that I must console to the AP to make any changes at all.

    Here is an overview of my AP configuration, with relevant parts removed for safety...

    OK means your AP is to have IP vlan2:

    Do it like this and try again:

    !

    interface Dot11Radio0.2
    encapsulation dot1Q 2
    encapsulation dot1Q 2 native
    Group 1 bridge
    Bridge-Group 2
    !
    interface FastEthernet0.2
    encapsulation dot1Q 2
    Group 1 bridge
    encapsulation dot1Q 2 native
    Bridge-Group 2

    !

    Or alternatively, you can delete the name native dot11radio0 and fa0.2. (It should also work without it), but be sure that for vlan 2 you have bridge Group 1.

    Blu and Billy showed you the 'real' solution. You can display the data returned by a cursor ref in SQL Developer, too:

    http://www.thatjeffsmith.com/archive/2011/12/SQL-Developer-tip-viewing-refcursor-output/

    Yet as a duty for a beginner is generally do not have the expected solution. Usually, teachers want to see you using a LOOP and dbms_output. something like

    DECLARE

    Xy CURSOR IS

    SELECT whatever

    As much as;

    BEGIN

    FOR r IN xy LOOP

    dbms_output.put_line (r.col1 |' # ' | r.col2);

    END LOOP;

    END;

    Of course this suggestion will inaugurate a discussion abusing DBMS output but I keep my position that it is authorized to use it for learning the basics.

    Once I do a text comment and click outside the comment, my comment fades lighter than the color of multiple shades, in which it was typed. Someone knows how to fix this?

    Maybe the opacity for the comments of text setting is set to a value lower than 100%... The problem is that there is no way to change it except by using a script.

    Here's how you can do it. After you have created your comment, click on it with the mouse and press Ctrl + J to open the JS Console window.

    In the lower part of the window clear the text that is there and enter this instead and then press Ctrl + Enter:

    this.selectedAnnots [0] .opacity = 1;

    This should change the level of opacity for the comment selected 100%.

    If it works then right click on the comment, go to properties and then click on the 'Make default properties' box and click OK.

    It should now be fixed for any comment that you create.

  • RICs when MergeTable using with the names of multiple tables

    Hello world!

    I just saw, as v11 OWM MergeTable media with the names of multiple tables. As I couldn't find anything in the documentation, here's a question:

    It also means, that RICs are automatically taken into account regarding the order of INSERTS/CHANGES/DELETES?

    That would actually really great and simplify the merge of our application mechanism a lot.

    Kind regards

    Andreas

    Hi Andreas,

    This feature works the same MergeWorkspace, but with a smaller set of tables.  Tables will always be merged into the order of the child table first, then the parent tables.  However, foreign key constraints are not validated until all tables have been merged.  This would prevent a mistake to be triggered when the child table merging before the parent merging table data in the parent workspace.

    Kind regards

  • Using the index of multiple values

    Hi guys,.

    Trying to assess the benefits of the addition of index of multiple values, a quick question on the index of multiple values:

    Here's my content from the cache:

    Key (EmpID), value [employee (age int, double salary, Department of String)]
    (1, new employee (25, 35000.0, "Admin"));
    (2, new employee (22, 30000.0, "Admin"));
    (3, new employee (34, 40000.0, 'Communications'));
    (4, new employee (36, 41000.0, "Admin"));
    (5, new employee (36, 42000.0, "HR"));
    (6, new employee (29, 30000.0, "HR"));
    (7, new employee (51, 50000.0, "BackOffice"));
    (8, new employee (36, 35000.0, "HR"));
    (9, new employee (46, 45000.0, "Admin"));
    (10, new employee (48, 47000.0, "HR"));

    If I still want to find all employees in the 'Human resources' Department and whose salary is more than 35000.

    Eventually, I would like to do the following:
    ValueExtractor salExtractor = new PofExtractor (Integer.class, 2);
    ValueExtractor depExtractor = new PofExtractor (String.class, 3);
    cache.addIndex (salExtractor, false, null);
    cache.addIndex (depExtractor, false, null);

    EqualsFilter departmentFilter = new EqualsFilter (depExtractor, 'HR');
    GreaterFilter salFilter = new GreaterFilter (salExtractor, 35000);
    Filter allFilter = new AllFilter (new filter [] {departmentFilter, salFilter});
    Employees value = cache.entrySet (allFilter));

    For my usecase above how can I use the indexing of multiple values to the same query?
    ValueExtractor salExtractor = new PofExtractor (Integer.class, 2);
    ValueExtractor depExtractor = new PofExtractor (String.class, 3);
    MultiExtractor mExtractor is new MultiExtractor (new ValueExtractor [] {salExtractor, depExtractor});.
    cache.addIndex (mExtractor, false, null);

    But how can I use the extractor to create multivalued filter queries for employees in the Department of human resources with greater than 35000 salary? Any ideas are much appreciated.

    I remember, values multiple index refers to a different concept: a multivalued index means that you can retrieve a collection of values of similar role of an attribute on which you can do Contains, ContainsAll filtering, and ContainsAny.

    In this case to fully the lever consistency of querying capabilities, you would
    - either add a sorted index with a custom comparator that compares the tables containing a salary and a Department on a first salary so the base of the Department and add a filter custom which is able to take advantage of the index for the request for the salary and also able to filter on the element of the array of index service
    -Add two independent indices (a sorted index of wages and a unsorted for the Department), in which case you can leverage all existing (GreaterThanFilter, EqualsFilter and AndFilter) code
