Multiple Xserve RAID's presented to one XServe

Can more than one Xserve RAID box be presented to a single XServe computer? The XServe user manual indicates only the upper PCI slot may be used for a FC HBA. A dual port FC HBA allows me to connect to one Xserve RAID- both controllers. If I want to connect to additional XServe RAID boxes, what are my options (other than XSAN)?
Thank you in advance.

It has always been my understanding that this is possible, but I haven't actually configured such a system. If you want "real world" confirmation you may have to check with Camelot or DaddyPayCheck about this exact set-up. I have experience plugging multiple Xserves into single RAIDs but not the other way around yet.
I have done the logical equivalent and hooked up an Xserve to a switch with only one cable (the other routed to a backup device) and had two RAID sides attached to the switch which worked fine.To me this demonstrates the "sides > connector" set-up as functional but I understand if you want more proof.
Apple assumes you're going to switched fabric set-up once you pass 1 to 1 connections and multiple RAIDs attached to the fabric are not a problem. You do, of course, loose the ability to push the edge of performance so something HD video in this environment is not feasible.

  • How to connect multiple Xserve Raid for Best Performance

    I like to get an idea how to connect multiple Xserve Raid to get the best performance for FCP to do multiple stream HD.

    Again, for storage (and retrieval), FireWire 400 should be fast enough. If you are encoding video directly to the external drive, then FireWire 800 would probably be beneficial. But as long as the processing of the video is taking place on the fast internal SATA drive, and then you are storing files on the external drive, FireWire 400 should be fine.
    Instead of speculating about whether it will work well or not, you need to set it up and try your typical work flow. That is the only way you will know for sure if performance is acceptable or not.
    For Time Machine, you should use a single 1.5TB drive. It is likely that by the time your backup needs comes close to exceeding that space, you will be able to buy a 3TB (or larger) single drive for the same cost. Also, I would not trust a RAID where the interaction between the two drives is through two USB cables and a hub. If your primary storage drive fails, you need your backup to be something that is simple and reliable.
    Oh, and there should be no problem with the adapter, if you already have it and it works.
    Edit: If those two external drives came formatted for Windows, make sure you have use Disk Utility Partition tab to repartition and reformat the drive. When you select the drive in the Disk Utility sidebar, at the bottom of the screen +Partition Map Scheme+ should say *GUID Partition Table*. When you select the volume under the drive in the sidebar, Format should say *Mac OS Extended (Journaled)*.

    My family has multiple iPhones.  Can we use one Apple ID for all of our phones?

    If you use the same AppleID for iMessage and iCloud though, you will all be sharing the same message account and iCloud email account.  You can use a common AppleID for purchased content, but each create your own unique AppleID for iMessage and iCloud so you each have your own private accounts for those services.

    How do you select and move more than one bookmark at a time?
    Shift+Click does not select multiple items that are next to one another in a list because the items open in firefox before this happens.

    Use the bookmarks library. You may use Shift +Click, and Ctrl + Click to create groupings of selected bookmarks to drag and drop.
    * one method of opening the bookmarks library is keyboard shortcut <br /> Ctrl+Shift+B (Windows)
    *see also [[How to use bookmarks to save and organize your favorite websites]]

  • How do I delete multiple items at once instead of one at a time?

    How do I delete multiple items at once instead of one at a time? I have several duplicate items in my library and would like to delete the duplicates. Thanks!

    You can select multiple items using shift to select a range and control to add or remove items from it.
    Regarding duplciates, Apple's official advice is here... HT2905 - How to find and remove duplicate items in your iTunes library. It is a manual process and the article fails to explain some of the potential pitfalls.
    Use Shift > View > Show Exact Duplicate Items to display duplicates as this is normally a more useful selection. You need to manually select all but one of each group of identical tracks to remove. Sorting the list by Date Added may make it easier to select the appropriate tracks, however this works best when performed immediately after the dupes have been created.  If you have multiple entries in iTunes connected to the same file on the hard drive then don't send to the recycle bin. This can happen, for example, if you start iTunes with a disconnected external drive, then connect it, reimport from your media folder, then restart iTunes.
    Use my DeDuper script if you're not sure, don't want to do it by hand, or want to preserve ratings, play counts and playlist membership. See this thread for background. Please take note of the warning to backup your library before deduping, whether you do so by hand or using my script, in case something goes wrong.

  • How to have multiple preference files for Mail on one computer

    I would like to have multiple preference files for Mail on one computer, one copy for each person in the organization. I want everybody to log in as the same user. Is this possible?
    Thanks,
    John Link
    Cube, 450 MHz, 640 MB   Mac OS X (10.3.9)  

    Since the Mail.app preference file (along with all other application preference files for a user account) is stored in that user's Home folder/directory, I don't believe this is possible.

    How can I print multiple copies of same photo onto one page on iPhoto 9.5.1? I was able to do it on the old iPhoto, but can't seem to be able to do it on the new iPhoto. Grrr...

  • Multiple instances of ECM 11g on one server

    I've read a few posts about installing multiple instances of ECM 11g on one server, but I have a few questions. My current set up is
    A single Windows 2008 Server R2 server
    8 gb RAM
    Weblogic 10.3.5
    1 install of ECM 11g in the base_domain
    Database is Oracle 11.2
    I want to add another instance of ECM to this server, but when I went to run the RCU, I was not allowed to use the same prefix for my tablespaces. Is this expected? I'm fine with using a different prefix, I just was surprised to see that I couldn't use the same prefix on this install since I was using a completely different database.
    Assuming I use a different prefix... do I just add a new domain for this additional ECM instance? Is there anything else I need to know?
    Thank you

    I went to run the RCU, I was not allowed to use the same prefix for my tablespaces. Is this expected?Yes. It will create tables with the same name visible for a different database user (thus, the prefix).
    do I just add a new domain for this additional ECM instance? Is there anything else I need to know?Actually, I think you can even install more instances to the same domain (this is more a question to Weblogic Server admins - I think there's been some posts recently on this topic). What definitely must be unique, is the port number. If you are OK with using different port numbers for your instances, it should be relatively easy. If you need the same port (e.g. 80 because of proxy limits), there are some ways how to redirect - it that case, two domains might be required.

  • HT1911 Multiple Apple ID's with my one iPod

    I accidentally have multiple apple ID's with my one iPod. Everytime i updated my email account, it created is an entirely new ID. Now, I want to transfer music between computers and songs purchased under old ID's can't be transferred because I don't recall old passwords. When I try the password reset process, it asks for my birthdate. I answer that correctly but it says that my answer is incorrect. now what?!?!?!?! HELP please!!!

    You must use the same Apple ID on all devices for all of the downloads and content to sync across all devices. If you each have your own Apple ID - you cannot automatically download content from your phone to his or the other way around. If you share the same ID - you can.
