Newbie here...Need help for XServe RAID w/ XSAN in Vid Editing environment

We're establishing an XSAN environment for video editing work flow. We're not new to SAN technology or video editing, but we are new to Xserve RAIDs, XSAN technology, and marrying them together in a production environment.
We have an XServe RAID at 14x750GB configuration. 1 Xserve metadata server, 1 Xserve Quicktime server, and 4 editing stations (2 MacPro's, 2 G5's) that are in the fiber channel fabric. Each machine has dual channel 4GB cards.
My PLEA for help concerns any advice this community can offer on RAID configuration, and XSAN configuration to achieve maximum performance. Settings, configurations, etc.
XServe, XServe RAID, XSAN, MacPro, G5 Mac OS X (10.4.9)

Were on the same boat but more like a life jacket
We only need the Fibre for back-up.
We have a single Avid Adrenaline on MacPro.
One Xserve that basically acts as a server for fonts, audioclips, photocatalog and minor back-up via gigabit ethernet.
Three G5s/MacPro/PC with 2/4GB FC installed.
One 10.5 TB Xserve RAID.
Last but not least a QLogic 1400 SAN box for Fibre.
Nothing is installed yet as were waiting on our Apple rep for some answers with Xsan.
Were not serving anything as far as external network and everything stays within the confines of our studio.
My question is that are we missing anything other than maybe getting more ports on the SAN.
We can live with a few workstations in the fabric.
Thanks in advance

  • Newb here, need help! just check out what i have, make reccomendations please!!

    Windows xp 32-bit,
    4 gigs ram,
    dual sli 7200 nvidia cards,
    60gb internal hardrive, 1.5 terabyte external hard drive (brand new, very empty)
    Recorded 24p and 60i on a Canon XL-2 (miniDV)
    IEEE 1394 firewire connected from pc to uploading device. Unfortunatly i borrowed the xl-2 from school, and am trying to capture from a panasonic pv-gs36 i borrowed from a friend (only friend with a device that records with a miniDV cam).
    I have been working fine on premier, very smooth when i import files, but when i tried to capture, as soon as i hit capture it freezes my whole set up, i have to manually restart my pc. I need to capture and export these clips to quicktime so i can edit in final cut at school (as requested by my instructer) the project is due in exactly one week, and the edit bays are always full which is why i opted for capturing at home with premier cs4.
    Im in panic mode now though, cause of this freeze issue. I'll have access to an xl-2 for the remainder of the week if the panasonic cam is the problem, but if not, please let me know!! ill go out and buy a new graphics card if that really is the issue... but i cant afford the quadro....which is why i opted for adobe premier instead of avid.
    im thinking its freezing because i recorded on an xl-2 and am trying to capture on this panasonic cam... could this be why?
    i installed premier on the 60 gig internal hard drive...should i uninstall it and install it on the external 1.5 tb one? should my settings be a certain way when i start a new project? Please help out a stressed out student during finals week! I will be super grateful to any info anyone can provide. thanks again for all your time and effort =)

    I'm unsure if the external drive is eSATA. I did buy it a few days ago 1.5 tb for 129.99 at fry's...good deal. What are the advantages of having an eSATA? The drive i have is a seagate Free agent-Desk external drive, model number st315005fda2e1-rk
    <img src="http://www.thinkdigit.com/uploads/seagate_freeagent_desk.jpg">
    Again, total noob here...
    the external is USB 2.0, and yea, i only have 1 firewire port. Also, something i failed to  mention is...I actually run my computer off my 42 inch samsung hd tv (720p native). When i was installing the whole production suite it asked me to get a moniter with higher resolution, but the click top continue installing anyway button was there so i went for it. Could this be the problem?
    I'm fairly sure i recorded in standard play with 2 channel audio with the canon, so im starting suspect it is this dinky panasonic dv cam thats causing me all this headache.
    also....please dont insult me too much...but:
    whats a panny?
    Whats scenalyzer?
    annnnd finally, no input on the cards? I was thinking that was going to be the problem for sure. The cards are great for gaming but im not really sure what kind of cards are (at least decent) for editing and capturing.
    I appreciate your help, ive been looking at the boards all night and this morning, i noticed you are kind of a superstar around here Millaard, so i really appreciate the effort =)

  • Newbie here needs help with features.

    I hope I'm doing this right.
    Problem #1
    With my storm when I make a call the key pad for the phone goes away. This is problematic especially when I'm checking voice mail. It is prompting me to enter my access code and i'm trying to get the key pad  to display itself. what do I do? Can I lock the key pad to display while making calls?
    Problem #2
    When entering a contact or a message that has several strings of number how do I get the Number pad to stay displayed so it does not toggle back to the alpha key pad?
    Problem #3
    Removing unused applications.How do I do it?
    Problem#4
    I am on an enterprise server how can I remove email accounts? I get two displays of the same emails comming in. They all come into a application marked messages then I get a second display with just messages for the email address showing on the application box. It is confusing and a duplication. 
    Thanks to anyone that can help me resolve these problems!

    Greetings, and welcome to the BlackBerry.com Support Forums.
    It is always helpful to receive help, to include your exact BlackBerry device model # and carrier name, so that when you have a question, that information won't need to be asked up front. Also, stating your device Operating System version is normally another common question, found on your BlackBerry at Options > About, third line down, looks like "v4.x.x.xxx"
    1. When on the call, yo'll see at the lower left a keypad symbol. Press it to bring up the keypad.
    If that doesn't appear or work, answer those above. There was one OS release way back that had a glitch of not allowing the keypad to show at all when calling.
    2. Message.. as in email? Press and hold the lower left numeric symbol on the keypad a full second the numeric keypad will lock in. Press the Alpha character at the lower left again to revert back.
    3. Most can be removed simple at Options > Advanced > Applications. Scroll to the application name and press Menu > Delete. Later OS releases will be at Options > Applications.
    4. Answer my questions above about the model and OS. The Storm1 and 2, according to the OS release vary on this.

  • Need help in creating RAID 5

    Hi everyone,
    i'm fairly new to RAID scene and i need help for creating RAID 5 with 8 disk's. 
    I have HP ProLiant DL380 G6 with 8 disk's, each 500 GB.
    i'm trying to create RAID 5 and to have one spare disk. I have made array from 7 disk and then create logical drive.
    the last disk (8-th) i used as spare. 
    up to now i think i'm ok???
    what confuse me is:
    7 HDD X 500GB= 3500GB
    after creating array i get 3200 GB, where i lose 300 GB??
    after creating logical drive i get 2700 GB, where i lose 500 GB???
    from 2700GB i give 150GB for system partition and for data storage i have only 2550 GB.
    Why i lose 800GB??
    Can someone explain me how RAID 5 works, do i create it correctly and why i lose so much space???
    Is there other way to create RAID 5 without losing so much space? 
    Thanks you in advnce. 

    The first 'loss' you encounter (300MB) is due to megabyte counting/rounding.  A 500GB disk contains about 500.000.000 bytes. This quite a bit less than if counted properly using binary. you loose about 24288000 bytes per disk this way!
    http://en.wikipedia.org/wiki/Mibibyte |
    http://en.wikipedia.org/wiki/Megabyte
    the second loss is due to how raid works.in raid 5 data is written to multiple disks to improve reliability. the simplies t form uses 3 disks: a write will cause half of the data to be written to disk 1, half to disk 2 and the XOR of both datahalfs to disk
    3. In this scenario you will loose 33% of storage space and you can loose up to one of 3 disks.
    By adding more disks, data can be spread more and the ratio available/raw will increase, or you can write aditionnal crc data and increase resliency for failures.
    http://en.wikipedia.org/wiki/RAID
    To check the exact algoritmes using on you RAID adapter, I would recommend contacting the vendor (or checking their support site) From your numbres, I do not think you will be able to configure RAID 5 on the same disks and having more available
    space for your data.

  • Repair Utility for  xServe RAID?

    We have an xServe with an attached RAID consisting of four 350 GB drives. The drives are set up as a RAID. Due to storms/hot weather (air conditioning failed) the server restarted and the RAID powered down. The xServe is fine but the RAID is not functioning. From RAID Admin the drives all show up and are OK but the array is not showing up. Is there any disk repair utility that would be useful on a RAID?
    xServe RAID   Mac OS X (10.4.6)  
    xServe RAID   Mac OS X (10.4.6)  

    The fact that it's showing up as spares is a significant problem. The host won't recognize it until the RAID recognizes the array. There is no separate utility to help you with this, other than RAID Admin.
    What firmware version is on the array? If it's 1.5, there's a "recognize array" option that you should try. If it's an older version, I'd tell you it would be nice if you could have gone back in time and upgraded the firmware. Since that's not possible, you should call AppleCare (assuming you have got APS&S for Xserve RAID, or the machine is < 1 year old) and inquire about your options.

  • Need help for flash builder

    i need help for flash builder 4 and papervison 3d. I need to create a slider with it ranges of value from 10 to 50 to adjust the camera values for the camera.fov and also need to create it for the yaw of the object from 0 to 360. I try to look for any slider event and classes in this program but cant find any, btw, i need to use the AS only project file.
    here is my codes:
    can you please tell me how i should modify the codes?
    package
        import flash.display.BitmapData;
        import flash.display.Sprite;
        import flash.events.Event;
        import org.papervision3d.materials.BitmapFileMaterial;
        import org.papervision3d.materials.BitmapMaterial;
        import org.papervision3d.objects.primitives.Sphere;
        import org.papervision3d.view.BasicView;
        [SWF (width="800", height="600", backgroundColor="0x000000",frameRate="30")]
        public class EarthBitmap extends BasicView
            private var sphere:Sphere;
            public function EarthBitmap()
                super(800 , 600);
                var earthmaterial:BitmapFileMaterial = new BitmapFileMaterial("../assets/Earth.jpg");
                sphere = new Sphere(earthmaterial,100,20,18);
                camera.fov = 25;
                scene.addChild(sphere);
                addEventListener(Event.ENTER_FRAME,rotateSphere);
            public function rotateSphere(evt:Event):void
                sphere.yaw(0.2);
                singleRender();

    Turn the click handler into a full on separate function. Then store all the views in an array and use Math.rand() to randomly choose one.
    Something like this:
    <fx:Script>
         <![CDATA[
              var questionsArray:Array = {question2,question3,question5,questionRed,questionGeography};
              function buttonClickHandler(event:MouseEvent){
                   var randomProblem:int = Math.floor(Math.random()*(questionsArray.length));     //generates a random integer between 0 and the total number of questions in the array (arrays are 0-based)
                   navigator.pushView(questionsArray[randomProblem]);
         ]]>
    </fx:Script>
    <s:Button id="randomProblemButton" label="Next Problem" click="buttonClickHandler(event)" />
    Haven't tested that, but something along that line should work

    How does the 6500 slide hard reset?
    That's simple.
    All you have to do is:
    From MENU goto SETTINGS, When there scroll down and select 'Restore Factory Setting'.
    There are two options in there:
    "Restore Settings only"
    and
    "Restore all"
    Select "Restore All"
    When done the phone will delete every thing on the Phone memory(C:\)(contacts,picture,messages etc)
    and also restore phone to its original settings and will restart.
    This proceedure is mostly common on S40 phone.
    Hope this explain and solve the problem.

    Don't flag your question as urgent, even if it is for you.
    * We all answer questions here voluntarily, in our leisure time. We do that because doing so is fun for us, because we enjoy helping people and having interesting discussions. Guess what, it is much less fun if it gets stressful. So the last thing you want to do to get us to answer your question is to pass your stress over to us.
    * People who are stressed and want a fast answer often don't even find the time to do the necessary research or to formulate their question in an easy to comprehend way. That's even less fun to work with. So you really don't want us to feel your stress. Instead you want to take your time to write a well formulated post that is fun to answer. The less likely it is for us to know that your question is urgent, the more likely you are to get a fast answer!
    * The simple notion that you want your post to be answered faster than those of the other members might feel rather unfair to some of us. Doubly so because often "urgent" questions actually are homework questions. Yours might be different, but someone who had bad experiences with this type of question might not read far enough to notice.
