Best practices for sharing a SAN-attached tape loader between servers.

When configuring zones to allow a tape loader to be shared by multiple servers, is there a preferred zoning method?
For instance, I have my primary fabric configured so that the zone for each data server using a LUN on my array consists of the primary port of the HBA on the server and the primary port of the HBA for each controller on my array.
My backup server does not use any LUNs on the array, so its zone consists solely of its primary HBA port and the HBA port of the tape loader.
If I want give my data servers access to the tape loader, should I add the tape loader's port to the zone of each server, or should I add the port of each server to the zone that currently consists of only the backup server and the tape loader?
Or does it matter?
The network is small:
One Windows server dedicated to backup, three NetWare servers handling data storage and 12 other VM servers running a mixture of Linux, NetWare, and Windows that handle various services but don't contain any significant amounts of data.
My intent is to give the 3 data servers access to the tape loader directly, so that their backup streams don't involve the LAN.
The remaining servers are small enough that backing them up over the LAN is not an issue.
I doubt that it matters for this, but the SAN switches are MDS9124's and the SAN array is an HDS AMS2100 with active/active controllers.
All server HBA's are dual port, as are the HBA's on each array controller.
In addition to the primary zone, each server and the array controllers are attached to a failover zone via the 2nd port of the HBA's.
Unfortunately, my backup software doesn't support NDMP, so I can't back up the array LUN's directly to the tape loader.

NDMP is for backing up NAS platforms.
Does your backup software support "LAN-Free" backup ? Typically enterprise backup software like Netbackup, TSM, Networker require a special license/agent that gets loaded on server where you are going to implement LAN-Free backups. Without that software/license servers will be fighting for tape resources and it will be a mess (if it works at all). Also you want to use dedicated HBA or port on dual HBA for tape traffic, do not mix tape and disk traffic on the same HBA/port. In big shops people configure dedicated "tape" VSANs but that would be an overkill for your current environment.

  • Best practice for sharing data with model window

    Hi team,
    what would the best practice for sharing data with a modal
    window be ? I use a modal window to display record details from a
    record list, but i am not quite sure how to access the data from
    the components in the main application in the modal window.
    Any hints would be welcome
    Best
    Frank

    Pass a reference to the parent into the modal popup. Then you
    can reference anything in the parent scope.
    I haven't done this i 2.0 yet so I can't give you code. I'll
    post if I do.
    Oh, also, you can reference the parent using parentDocument.
    So in the popup you could do:
    parentDocument.myPublicVariable = "whatever";

  • Best Practices for sharing media with iMovie and FCPX

    So I've a large iMovie Events directory, and would like to use that media with both iMovie and FCPX projects.
    I'd rather not duplicate the media, so would prefer to import as references into FCPX.
    The dilemma is that I see that it's possible to modify or move media from within the iMovie application, and therefore break the reference to that media with FCPX.
    I only see two options:  (1) Never Ever modify the location/name of media in the iMovie Events file (even from within the iMovie app) since I would break an FCPX link if that media is referenced, or (2) always import (copy) the iMovie events into the FCPX Event Library making an independent original so that I can confidently operate on those media files in either application.
    I'd surely rather not have to do (2 )(e.g. doubling my storage demands) to gain the flexibility of using either application to edit the video, but really don't want to live with the restrictions of (1).
    Thoughts / Solutions?  What might you consider as options or best practices?

    Unless there is some other reason, users should own the right to share their mailboxes - it shouldn't be something that demands administrator management (if only so that the administrators aren't swamped by user requests for sharing their mailboxes).

  • Best practices for sharing mailboxes

    Hello,
    To share mailboxes, I am not sure of the 'best practices'. 
    From my point of view, there are two scenarios :
    classic mailbox : an user A wants to share his mailbox so it assigns rights on his mailbox for an userB via Outlook. The userB will add the userA's mailbox to his profile
    shared mailbox : the rights are managed by the administrator
    Is it correct to divide the management (i.e classic user manages his own mailbox and the administrator manages rights on shared mailbox) or is not ?
    And the delegation functionnality in Outlook is not really what I want because the userB must have only access to the mailbox (+calendar+contacts) but he hasn't to manage the appointments, etc.
    Thanks for your help

  • Best practices for sharing iPhoto libraries across multiple Macs

    I have a pair of iMacs running 10.6.x. and iPhoto 11 connected via Ethernet to an Airport Extreme. I am looking for a way to share my iPhoto library between the two Macs.
    I found an Apple Support note on the topic (http://support.apple.com/kb/HT1198) which states that a disk image is a supported location for a shared iPhoto library (with limitations acceptable to me) and it strikes me that this would be a way of hosting a shared iPhoto library onto a NAS device.
    Am I missing a simpler solution or, more importantly, am I missing any blindingly obvious caveats? I'd love to hear from anybody who has tried this (successfully or otherwise) or anybody who has a better idea. I haven't bought a NAS device yet, so I'm open to alternative suggestions.
    Specific requirements:
    Members of my family use either one of a pair of iMacs.
    The only user who edits the iPhoto library is me and I only need read/write access from one machine.
    iPhoto library access limited to one user at a time is acceptable and practical in my case.

    Easiest:
    If the other users only get to see the Library then just use iPhoto Sharing.
    Enable sharing in the iPhoto Preferences on the Host machine, then go to the other macgine and in the same location enable 'Look for Shared Libraries'
    Other forms of sharing will give the users read/write access to the Library.
    A strong warning: If you're trying to edit the Library (that is, make albums, move photos around, keyword, make books or slideshows etc.) or edit individual photos in it via Wireless be very careful. Dropouts are a common fact of wireless networking, and should one occur while the app is writing to the database then your Library will be damaged. Simply, I would not do this with my Libraries.

  • Best Practice for Shared Contacts available as an Address Book in Outlook??

    Yep so crazy that Microsoft still refuses (by design) to enable address book option for Shared contacts!!!!!!!  So I am asking what do they suggest then for my clients to have a shared contact list that is available as an address book and available
    to sync to your phone?
    Problem:
    I have a client that the boss has a contact list in his outlook that he has synced to his phone that is shared so that everyone else on his team can see the contacts, since it is a shared contact list users are not able to add it to their address book (by
    design..nice design)
    Solutions I know of:
    1.Use public folder for contact list...= Nope public folder contact list will not sync with his iphone/ipad...(yes there are 3rd party tools but I would prefer to not go this route)
    2.Sharepoint....I have heard this one but don't know much about it.   How does it sync to outlook and phones?  Is it seemless?  can user add contacts in outlook?
    3. ??
    Seems like this would be a huge issue that microsoft would have fixed by now.  Let me know if anyone has any ideas... 
    Sbs 2003 I will miss you !!!!

  • What is best practice for using a SAN with ASM in an 11gR2 RAC installation

    I'm setting up a RAC environment. Planning on using Oracle 11g release 2 for RAC & ASM, although the db will initially be 10g r2. OS: RedHat. I have a SAN available to me and want to know the best way to utilise that via ASM.
    I've chosen ASM as it allows me to store everything, including the voting and cluster registry files.
    So I think I'll need three disk groups: Data (+spfile, control#1, redo#1, cluster files#1), Flashback (+control#2, redo#2, archived redo, backups, cluster files#2) and Cluster - Cluster files#3. So that last one in tiny.
    The SAN and ASM are both capable of doing lots of the same work, and it's a waste to get them both to stripe & mirror.
    If I let the SAN do the redundancy work, then I can minimize the data transfer to the SAN. The administrative load of managing the discs is up to the Sys Admin, rather than the DBA, so that's attractive as well.
    If I let ASM do the work, it can be intelligent about the data redundacy it uses.
    It looks like I should have LUN (Logical Unit Numbers) with RAID 0+1. And then mark the disk groups as extrenal redundancy.
    Does this seem the best option ?
    Can I avoid this third disk group just for the voting and cluster registry files ?
    Am I OK to have this lower version of Oracle 10gr2 DB on a RAC 11gr2 and ASM 11gr2 ?
    TIA, Duncan

    Hi Duncan,
    if your storage uses SAN RAID 0+1 and you use "External" redundancy, then ASM will not mirror (only stripe).
    Hence theoretically 1 LUN per diskgroup would be enough. (External redundancy will also only create 1 voting disk, hence only one LUN is needed).
    However there are 2 things to note:
    -> Tests have shown that for the OS it is better to have multiple LUNs, since the I/O can be better handled. Therefore it is recommended to have 4 disks in a diskgroup.
    -> LUNs in a diskgroup should be the same size and should have same I/O characteristica. If you now have in mind, that maybe your database one time will need more space (more disks) than you should use a disk size, which can easily be added, without waisting too much space.
    E.g:
    If you have a 900GB database then does it make sense to only use 1 lun with 1TB?
    What happens if the database grows, but only grows slightly above 1TB? Then you should add another disk with 1TB.... You loose a lot of space.
    Hence it does make more sence to use 4 disks á 250GB, since the "disks" needed to grow the disk groups can be extended more easily. (just add another 250G disk).
    O.k. there is also the possibility to resize a disk in ASM, but it is a lot easier to simple add an additional lun.
    PS: If you use a "NORMAL" redundancy diskgroup, then you need at least 3 disks in your diskgroup (in 3 failgroups) to be able to handle the 3 voting disks.
    Hope that helps a little.

  • Best practice for sharing LOV's over multiple Application Definitions?

    We want to define/generate (complex) LOV's in 1 place and use them in multiple sub-applications (different application definition files).
    What is the best practive to accomplish this?
    Frank

    Frank,
    Here is what you do:
    - Generate the LOV the "normal" way using your first app def file
    - In all other app def files, you create a "dummy" LOV group by the same name with the same items, so you can associate items with the LOV and specifiy return values
    - For each "dummy" LOV group uncheck the checkboxes "Generate Pages", "Generate Page Definitions" and "Generate Controller Group". (only visible in expert mode)
    - Make sure you first generate the first app def file before you run the [ages generated by other app def files.

  • Best practice for sharing html content on different group spaces?

    How can html content be shared between several group spaces?
    One way I have found is to add a html doc to ucm and then to add this doc as a iframe to a page.
    Are there other ways, like adding on one group space page a html layout element and then to view this content in a different space. How could this be done, with an expression language reference?
    Has someone experience in presenting the same html content on different spaces and can share how he does it. Any ideas are welcome.
    Thanks,

    Hey Max,
    Check out our technical whitepaper on Integrating ECM with Portal Technologies.

  • Best Practices For Household IOS's/Apple IDs

    Greetings:
    I've been searching support for best practices for sharing primarily apps, music and video among multple iOS's/Apple IDs.  If there is a specific article please point me to it.
    Here is my situation: 
    We currently have 3 iPads (2-kids, 1-dad) in the household and one iTunes account on a win computer.  I previously had all iPads on single Apple ID/credit card and controlled the kids' downloads thru the Apple ID password that I kept secret.  As the kids have grown older, I found myself constantly entering my password as the kids increased there interest in music/apps/video.  I like this approach because all content was shared...I dislike because I was constantly asked to input password for all downloads.
    So, I recently set up an individual account for them with the allowance feature at iTunes that allows them to download content on their own (I set restrictions on their iPads).  Now I have 3 Apple IDs under one household.
    My questions:
    With the 3 Apple IDs, what is the best way to share apps,music, videos among myself and the kids?  Is it multiple accounts on the computer and some sort of sharing? 
    Thanks in advance...

    Hi Bonesaw1962,
    We've had our staff and students run iOS updates OTA via Settings -> Software Update. In the past, we put a DNS block on Apple's update servers to prevent users from updating iOS (like last fall when iOS 7 was first released). By blocking mesu.apple com, the iPads weren't able to check for or install any iOS software updates. We waited until iOS 7.0.3 was released before we removed the block to mesu.apple.com at which point we told users if they wanted to update to iOS 7 they could do so OTA. We used our MDM to run reports periodically to see how many people updated to iOS 7 and how many stayed on iOS 6. As time went on, just about everyone updated on their own.
    If you go this route (depending on the number of devices you have), you may want to take a look at Caching Server 2 to help with the network load https://www.apple.com/osx/server/features/#caching-server . From Apple's website, "When a user on your network downloads new software from Apple, a copy is automatically stored on your server. So the next time other users on your network update or download that same software, they actually access it from inside the network."
    I wish there was a way for MDMs to manage iOS updates, but unfortunately Apple hasn't made this feature available to MDM providers. I've given this feedback to our Apple SE, but haven't heard if it is being considered or not. Keeping fingers crossed.
    Hope this helps. Let us know what you decide on and keep us posted on the progress. Good luck!!

  • Best practices for office 365 SHARED CALENDAR for whole school / organization

    hi
    we need guidance on best practice for setting up SHARED CALENDAR on Office365 exchange server for entire organization (school)of150 staff.
    Requirements
    + all staff should have read only / reviewer permissions on calendar
    +handful staff should have editor permissions on calendar
    + the calendar should synchronise custom categories and colors
    Current Solution
    at the moment we have found that a shared mailbox is the best solution because;
    - allusers can add the shared mailbox on outlook 2010as additional mailbox as readonly
    - all the categories & colors for the calendarare automatically synchronised because the color categories are stored within this mailbox.
    - you can edit calendar permissions in outlook to allow some users as "editor" of the calendar.Problem with Current Solution
    the problem however is that the users also need to access this...

    Hi Aleksei,
    I think Inactive mailboxes in Exchange Online is the feature that you want. This feature makes it possible for you to preserve (store and archive) the contents of deleted mailboxes indefinitely.
    A mailbox becomes inactive when an In-Place Hold or a
    Litigation Hold is placed on the mailbox before the corresponding Office 365 user account is deleted.
    But I'm afraid that it might be impossible to "easily share certain folders or even whole mailbox with people in the company". As can been seen from below articles, this only allows administrators, compliance officers, or records managers
    to use the In-Place eDiscovery feature in Exchange Online to access and search the contents of an inactive mailbox:

    Exchange Online, where you can get more experienced responses:

  • Best Practice for External Libraries Shared Libraries and Web Dynrpo

    Two blogs have been written on sharing libraries with Web Dynpro DC, but I would
    like to know the best practice for doing this.
    External libraries seem to work great at compile time, but when deploying there is often an error related to the external library not being a deployed component. 
    Is there a workaround for this besides creating a shared J2EE library which I have been able to get working?  I am not interested in something that works, but really
    what are the best practice for this. What is the best way to  limit the number of jars that need to be kept in a shared library/ext library.  When is sharing ref service/etc a valid approach vs. hunting down the jars in the portal libraries etc and storing in an external library.

    Security is mainly about mitigation rather than 100% secure, "We have unknown unknowns". The component needs to talk to SQL Server. You could continue to use http to talk to SQL Server, perhaps even get SOAP Transactions working but personally
    I'd have more worries about using such a 'less trodden' path since that is exactly the areas where more security problems are discovered. I don't know about your specific design issues so there might be even more ways to mitigate the risk but in general you're
    using a DMZ as a decent way to mitigate risk. I would recommend asking your security team what they'd deem acceptable.

  • ASM on SAN datafile size best practice for performance?

    Is their a 'Best Practice' for datafile size for performance?
    In our current production, we have 25GB datafiles for all of our tablespaces in ASM on 10GR1, but was wondering what the difference would be if I used say 50GB datafiles? Is 25GB a kind of mid point so the data can be striped across multiple datafiles for better performance?

    We will be using Redhat Linux AS 4 update u on 64-bit AMD Opterons. The complete database will be on ASM...not the binarys though. All of our datafiles we have currently in our production system are all 25GB files. We will be using RMAN-->Veritas Tape backup and RMAN-->disk backup. I just didn't know if anybody out there was using smallfile tablespaces using 50GB datafiles or not. I can see that one of our tablespaces will prob be close to 4TB.
