Can I use a thunderbolt DAS with 3 projectors and 1 display?

Hi, I want to know if is possible to use a Thunderbolt DAS (Promise Pegasus), with 3 HDMI projectors and 1 HDMI display (with active adapters), and have good performance with the DAS.
Thank you

In the Mac Pro late 2013, there are three ThunderBolt busses, each of which has two connectors. There is plenty of bandwidth to do the I/O you are talking about. As long as resolutions are 1080p or less, that fits nicely in HALF of a ThunderBolt-2 Bus, and another device can use the other half.
The Pegaus is limited by the speed of the drives and how many are actually active at once. Typical rotating drives can source data off the platters in the neighborhood of 125MBytes/sec, or about 1,000M bits/sec. Half a ThunderBolt-2 is ten times that.
You have specified too many HDMI displays, (which are considered "legacy" displays) for easy, cheap hookup. You will need mostly ACTIVE adapters, such as StarTech ACTIVE Mini DisplayPort to HDMI, about US$40 each.

  • Can I use HP Pro 8600 with usb and wireless at the same time

    Can I use HP Pro 8600 with usb and wireless at the same time?  Sometimes I cannot get the wireless to work, it seems to be my laptop.  It would be nice if I could use the usb, but it doesn't work.  What should / can I do, if anything?
    Sam

    Hi,
    Same physical printer but when connecting to SAME computer using both USB and wireless it becomes two (logical) printers. Probably your default prnter is the wireless one, you have to select the right printer before print .

  • How can i use external hard drive with mac and pc!

    I've been using a Lacie external hard drive with my mac to keep the itunes library and other things since day one. Since i have a dvd with files for windows and an old pc without a dvd drive, i decided to copy and paste the content of the dvd to the external hard drive. The only problem now is that when i plug the external hard drive to pc, it won't open. I know it has to be formatted in a different way, but i need to find out the best solution!
    Any idea?

    You can format the external drive in Fat32 (which I don't recommend but is the most compatible between both platforms), or NTFS (which requires some work to get your Mac to recognize), or HFS+ (which requires special software on your PC so your PC can use it).
    If you use this drive mostly with your Mac, get MacDrive for your PC:

    If you use this drive mostly with your PC, here's some software for you Mac. I haven't tried this myself, but the professional reviews have been good:

  • Can you use a custom cursor with drag and drop?

    Hi there! I'm a newbie flash user and working on a simulation for a graduate course in instructional design. I'm using Flash Professional CC on Mac. Here's what I'm trying to do. I have several draggable sprites on the stage and three target sprites. I have specified the original x,y locations of the sprites and have set the end x,y locations as those of each of the three targets. Items must be dragged to one of the three targets.
    Some questions:
    1. Can I specify more than one End x,y location for a draggable sprite? I'm creating a lesson to teach kindergartners how to sort lunchroom waste. If they have a napkin, for example, it could either go into the compost OR into the recycling. In cases like this where an item could really be placed into more than one bin, I want them to get it right if they do either of those things, rather than forcing them to choose which one.
    2. To make my project more "fun" for kids, I wanted to customize the cursor with a graphic of  hand. When I tried this in the flash file it works perfectly until I add the drag and drop functionality for the wasted items. Then the cursor will more around  but not pick up any items. Once I revert back to the standard pointer, the correct drag and drop functionality is restored.
    3. I have it set to snap back to the original location if learner attempts to drop the item on the wrong target. I want to be able to play a sound file when that happens, as well as play a sound file when it lands on the correct target, as well as shrink the item and change its opacity so that it appears invisible. I want to give the illusion of it being placed into the bin. I have no idea as to the proper way to code these events so that they happen.
    4. I've watched dozens of hours of youtube tutorials before coming here. I'm a quick study, but am very new to action script. In one of the videos the developer showed referencing an external action script file which I don't think is an option in CC.

    assign your cursor's mouseEnabled property to false:

I want to give the illusion of it being placed into the bin. I have no idea as to the proper way to code these events so that they happen.
    use the sound class to create a sound:
    // initialize your correct sound once with
    var correctSound:Sound=new CorrectSound();  // add an mp3 sound to your library and assign it class = CorrectSound
    // apply the play() method everytime you want your sound to play:
    correctSound.play();
    // change an object's opacity:
    someobject.alpha = .3;  // partially visible
    someobject.alpha = 1;  // fully visible
    someobject.visible=false;  // not visible, at all.

    you could google:

    p.s.  you can simplify and streamline your coding by learning about arrays and using hitTestObject.

  • Can I Use My Music Library With itunes and ipod if it's Only Saved to an External Hard Drive?

    I have very little space left on my internal hard drives. I have the same music library saved on an external drive.  To get some space back, can I delete my music library from the internal drive C and just use the library on the external drive? Will it work in my itunes library and ipod? I want to download more music but I'm afraid to right now, because there is hardly any space left!

    Rick,
    For everything you should know about Time Machine, see http://pondini.org/TM/FAQ.html.
    If your photos were on your internal drive then, yes, they are likely to have been backed up by Time Machine.
    However, if Time Machine starts running out of space, it will delete old back ups and thus your photos aren't really 'safe' just on a Time Machine back up. What you really need to do is either:
    Buy another external hard drive for storing your photos and other files, or;
    Back up your photos to DVD's: there are a number of cataloging apps that you can use to catalog your files or, if you have named them something specific, use something like DiskTracker.
    Either way, don't rely on your Time Machine back-up to store your photos.
    Good luck - call back if you need more information,

    Hi Scott,
    You should be able to. If the projector has a speaker with acceptable sound, that's one option, otherwise powered speakers or a surround system.
    What connections does the projector have?
    Exactly which MBP do you have?

    You do have Firewire 800 and it seems plenty fast for most use. Easy to install and the cradles allow for multiple disks swapping or daisey chain for multiple cradles.
