• How to work on the strategy of Distribution of the storage group?

  Any body can help me to understand the strategy of Distribution of the storage group?

  The App, the storage Volumes have the option below:

  Spread: Distribute files in all storage locations.
  When a file is created, the storage with the most available space is selected.

  Round-robin: Distribute files sequentially using the storage locations.
  When a file is created, with the oldest time used storage is selected.

  I don't know what is different from this two option. When I select this option, I can see on my environment? Thank you.

  I think that it is used only for writable volumes right?

  If you are using storage with appstacks groups all appstacks are synchronized between the two storage when you use the sync option.

  When you create writeable volumes in the storage group it will create in one of the stores of data defined in the storage group.

  Let's say your staorage is called ST1, ST2, ST3 and ST4 and ST1 and 2 are 100GB and 3 and 4 are 1000GO then that's what happens.

  East Round Robin

  ST1, ST2, ST3, ST4, ST1, ST2, ST3, ST4 and so on and so forth. It would take into space wanted account.

  With the other he will do

  ST3, ST4, ST3, ST4, until both have also 100 GB of disk space and it will then be evenly.

• EqualLogic - Volumes moving storage pools

  Hello

  I want to move a volume across storage pools this weekend but begins to wonder about something.

  I have 3 pools of storage all in the same group.

  Level 1 (2 ps3900xv)

  Level 2 (1 ps4000e and 1 ps4100e)

  Tier3 (1 ps6100xv)

  We go to the retirement of the 3900 2 because they are EOL. I have 4 books I want to move from level 1 to the Tier3. 3 volumes are my Exchange 2010 database and the 4th volume is my SQL databases.

  What I was wondering is can I move these volumes with database Exchange and SQL DB to live? From what I've been reading is claims of Dell you can. The part that worries me is I moved a volume of test and noticed that the iSCSI connections terminate (log out and back in) for a fraction of a second, and I don't want that affect databases.

  Thanks for the tips!

  Hello

  Yes, you can move the living.  Logout/login is necessary because you have moved the data to another Member.  This is handled through the iSCSI specification.  'S called it ASYNC logout and redirection of connection.   The table will display the initiator to disconnect a specific session.   When it goes back to the address of discovery, he is redirected to the new physical port.   All connections to an EQL array are handled this way.

  FYI: If there are many books on level 1, you can merge Tier1 and Tier3 in one step.  Then move a 3900 member to a temp pool, which will leave all the data on this member behind.  Then you can remove this member and repeat for the last 3900.    It's fewer steps in this way and you can start at night and let it run overnight.  The merge process is close to the trapezoids.  Because no page movement starts immediately.  Then merge, then select a member to an empty pool.  This will save time restriping data across the pool now three members.

  Either way works fine.

  Kind regards

• Orientation of storage group

  Hi all

  We are expanding our storage environment and wanted some advice on setting up our group/pools.

  We currently consisting of 12 TB PS4000E storage group, it is used as mass storage for files and archiving of mail servers. All volumes are in the default storage pool.

  We bought a 24 CT PS4100E and a 14 TB PS6100X to add to this group. The idea is to migrate existing data from Vault/e-mail on the server of the PS4000E file, so it can be removed from the Group and used elsewhere in the company.

  In scenario 1 we add two devices in the Group and separate storage pools and migrating volumes from the storage pool by default for the pool containing the PS4100E. Then remove the PS4000E of the group.

  In scenario 2 we have the PS4100E and the PS6100X in the same pool of storage and migrate the data in the same way. The group can then distribute the data as seems it.

  In the future we will migrate VM storage over another group, containing a PS5000.

  What are the considerations of raid level and pool for these scenarios? RAID5 has been recommended for both of the new features, but can they coexist in the same pool and work well with the same level of raid?

  Thanks in advance.

  Jim

  Yes, you can run different RAID levels in the same pool and through different speeds with him when to use the latest version of the firmware (5.x and v6.x).

  You can add new members in any combination you like (an a R10 two R10 or the two R6, or alone as a R6).  APLB (Automatic Performance Load Balancing) will examine various aspects of i/o, disk speed, type, RAID and determine the best placement for the slices of volume and move the data according to the needs (in the background) to provide the best performance.

  Just note that because the SAS bays generally have more space, volumes have generally several sections on the largest capacity table.

• Replication storage group

  Just a quick question about automated replication.

  I noticed that, sometimes, a stack of app will be automatically repeated at all storage in a storage group, as soon as the stack is created. Maybe it's just a coincidence of timing. Other times, I have to use the button repeated in storage group menu, which I am reluctant to do it because I guess, he is everything that the replication (in the case where there may be changes).

  Is there a timetable? Can I force replication just to a single appstack, for example by using a command line on the server?

  Just for reference, we use only local flash storage on the hosts for the non-persistent linked clones, so we need to replicate to all the machines see the battery.

  the timing is every 4 hours and no its not configurable. You can force replication, but not for a single AppStack. However if there is that one added and you force a replication, it will only replicate a new a

• CX3-20: host in several storage groups?

  Hi all

  What is the trick? I have all the storage groups created on our SAN access to our server VCB (Virtual Consolidated Backup of VMware).

  The problem is that our Clarion EMC Cx3-20 allow us only to add a host to a storage group.

  If I want to connect the VCB server to a different storage group, I get a prompt saying (in Navisphere):
  AMS - back.corp.com: this host is already connected to a different storage group. Connection to the current storage group will be be disconnected from the other storage group. This will cause the host unable to access the LUNS that are in the other storage group.

  VCB server must see all LUNS, can advise you?
  Thank you

  
  

• LOW 5.0 API search Exchange storage group

  I had a problem to find the location of the storage group Exchange (2003 environment) within the API 5.0.  I have no problem to find the name of the actual exchange server however I do not know which class contains the value real homemdb (if any.)

  Any help is appreciated,

  Thank you

  Rob

  Hi Rob,

  The BES does not connect to any Exchange database so that there is no API to return this value. All communication is done via MAPI.

  A good rule of thumb, if something is not possible to be found/made using the console BOTTOM it is not supported in the BAA.

• navigateToURL, app / app-storage dirs: what's the problem?

  I am using flash.net.navigateToURL to open the browser to display an HTML file located in the application directory (or the application storage directory, if necessary). None of the following two approaches work...

  // (1)
      var target:File = File.applicationDirectory.resolvePath(filename);
      navigateToURL(new URLRequest(target.url));
  // (2)
      var target:File = File.applicationStorageDirectory.resolvePath(filename);
      navigateToURL(new URLRequest(target.url));
  

  The PlayBook browser is opened, the HTML content is not displayed, but the following error message is:

  "This file could not be opened. Make sure you have the proper permissions and try again. »

  (Http:// URL works fine, but I was not able to get local files in the directories of the app or app-storage to work according to the approach above, or by using the path native discrimination, etc.).

  Any ideas, or operating code? (I'm running OS 2.0.1.358, BTW.)

  The error message says it all...

  The PlayBook, the apps are sandboxed. An application cannot access an another apps files. The browser is an application too. He cannot access the files in the private area of your application. This would have caused all sorts of security issues.

  Solutions: either copy your HTML in a public folder somewhere, or incorporate a StageWebView into your application and load the page in this.

• Unit - mailbox moved to the new storage group is not available

  Hello

  I have a 4.0 (4) unit UM with a message from Exchange 2003 offbox store. During the initial installation, only the first storage group on the mail server was present and mailboxes of the users are hosted here.

  Recently, a new storage group was created on the mail server and a mailbox has been moved from the first group of storage to the new storage group. The Subscriber is able to receive voice messages via e-mail, however his MWI does not illuminate. When it tries to connect to retrieve messages on his phone, the unit said "your messages are not available now.

  I am able to create or import users that are hosted in the new storage group, but I'm having the same symptoms. Is it necessary to rerun the configuration of message store wizard?

  Thanks in advance.

  Have you run Assistant permission for the new Bank of mailboxes?

  The other thing to do is to restart the AvMsgStoreMonitor service; But wait after hours. A reboot will do the same.

• Storage groups

  Hello

  At the start of SAN in UCS, what is the best practice when creating the storage groups in the drive Bay?

  For example, VMware: is it best practice to have a storage group for each ESXi and add its own ESXi Boot LUN (id = 0) and the necessary VM LUN data store?

  Other environments (Linnux, Windows, Hyoer-V) have something special in these terms to support?

  Thank you

  It's a security issue.  Because the LUN ID can be changed easily on the host computer, you could continuously clobber the LUN hurt if your server administrator has incorrectly changed LUN ID.  In addition, once a host is started, it will be able to see & access each LUNS in the storage group independently LUN ID.  The importance of the impacts host LUN ID matches only a host trying to start SAN.

  The two main forms of security applied to the storage is zoning and masking.

  Zoning - on storage switch, acts as an ACL restricting the scope of what can see the members of the zone.  An area will normally contain only a single host and target WWN.  * Who I can see *.

  Masking - on the table limits of storage 'what' LUN a host has access to.  This is done in the form of storage groups.  * What can I access *.

  Either work around poses a great risk to corruption or destruction of data given that different operating systems can be read their native file systems.  E.g. If you had all your hosts in a storage group (ESX, Windows etc.) and tried to separate them only by a LUN ID, a simple change of 1 digit of the start ID LUN on the initiator target could lead a crowd to not read the file system and potentially right a new signature to the risk - replace your existing data.  Windows cannot read a linux partition and vice versa.

  Follow these best practices and your data will be much more safe & secure.

  Kind regards

• appvolume Setup is complete but get error below when opening the web app-volume Manager interface. Cannot start the volume App Manager "cannot load this file - tiny_tds.

  "failed to start volume App Manager" boot failure Unable to load the file of this type - tiny_tds

  

  Hi Paul amstaur,.

  This question says, I've met before, and there is a permission problem. Please do below things to get rid of.

  Since you have already installed the app volume, go back to the snapshot, or install a vanilla OS. Provide a sufficient permission in the local security policy, if you install SQL express as well as the volume of the app as the backup Administrator, debug as an administrator, log in as a service to the domain user. Also make sure the time is correct on the computer. You must restart the computer after you gave permission.  Most of the cases you already have full filled what mentioned above, but still you get an error.  To get rid of it, you must copy the appvolume installation files to the local directory, may be in the C drive and recommending only not to mount the ISO in virtual CD ROM, instead of copy and extract the ISO locally.  the next important thing is that you must run the setup.exe AppVolume run as administrator.

• Writing in the app-storage inside the worker directory

  Hello

  In my Adobe AIR (desktop) application, I wrote a class FileDownloader using insternally an instance of FileStream to write remote files in the application storage directory

  The problem is that the user interface crashes during the download process (even if I open the local file asynchronously)

  As a solution, I thought it might be a good idea to use a worker to download these files, but when I try to write to the directory of storage app of my worker thread

  the worker, he writes in this folder: %appdata%\[Worker].null\Local Store

  As you can see, app storage directory is inside this folder named ".null [worker]" instead of being in my true app-storage dir (named by my ID app)

  A solution I found to write downloaded files in a tmp file, then, in the main Worker Thread, use moveToAsync to move the file to my app-storage directory, but it's not very clean... and moveToAsync takes time with large files...

  Has anyone experienced this problem?

  This is the normal behavior or is it a bug? I think that the worker should have the same app as application storage directory that integrate it (especially when you set giveAppPrivileges = true in the createWorker method)

  Thank you

  (and sorry for my English)

  Hello

  Having worked with several workers on my own project, I had the same behavior.

  The solution I found was to set a property that is shared on the worker and the native path of the application.

  So, on the key worker, you get the native path of applicationStorageDirectory and then set the property shared on the worker.

  It will be useful.

  Kind regards

  According to KB VMware: the size of the Volumes VMware App SQL database the Appvolumes database needs to be cleaned regularly.

  Given that not all Volumes App admins are database administrators, we don't necessarily have the right to do.

• Adding a lun to multiple storage groups

  Is it OK to have the same LUNS in storage groups? I'll put up a new cluster and its own storage group. But I need to have other LUN mounted in the other cluster so that I can migrate virtual machines to this new cluster

  Fix. It's all basically just of masking.
