How to connect many devices with only one FW800 port in iMac?

Hi,
I am upgrading to a new Intel iMac from a 2004 vintage Dual2.0GHz PowerMac. I currently have 8x d2 Quadra drives chained by FW800, and 2x Iomega drives connected vis FW400 hub which also connects HD cams.
My questions is that with only one FW800 port in iMac, I think my devices connectivity is the following?
(1) Get a FW 800 hub (I can only find 2 port ones at the Apple store and BestBuy)
(2) Connect the d2 Quadras to one port of the FW800 hub
(3) Get a FW 800 to FW 400 cable
(4) Connect my 6 port FW400 hub to the 2nd port of the FW800 hub
Thanks for reviewing this solution, and I would also appreciate other suggestions or hear about your experiences if you have a similar set-up.

In addition to your listed considerations, you should consider the following.
Many storage needs do not required FireWire 800 speed. For example, USB 2.0 works fine for your Time Machine backup drive. If you are just storing user data such as your iPhoto or iTunes media files, USB 2.0 is more than fast enough. So, as much as possible, if any of those external drives have USB 2.0 connections and the data storage does not need FireWire 800 speed, offload as much as possible to USB 2.0. I used to be a +FireWire snob+, but since getting an Intel iMac, I find that USB 2.0 works quite well for most data storage purposes.
There are new hard drives that are power efficient and as large as 2TB. Consolidate your data storage needs onto a smaller number of very large drives, partitioned as needed. This will make your setup more reliable (smaller number drives), and save reduce power consumption. If any of your current externals are SATA, you can probably replace the existing drive with an extra large one.
So, I think you setup should be, extra large FireWire 800 drive connected to the FireWire 800 port directly. Using a 9-pin to 6-pin cable, connect the FireWire 400 hub. Connect any non-storage FireWire 400 devices there. Do some data transfer testing to make sure having the 400 hub there on the chain does not cause the 800 connection to slow down.
Connect other drives as needed using USB 2.0, existing or new. Retire the smaller of your external drives.

  • How to sync 2 devices with only one iTunes ?

    I have iphone and my gf has ipod touch. We only have one computer - win 7.
    How can we sync it, so we can both have different music and apps on each device?

    The easiest way is method 2 from this article - just sync certain playlists to each ipod.

    If you both want your own song ratings and play counts, use method 1. It's more of a pain to set up and keep updated when new music is added, though.

  • How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?

    I have a mac pro connected by ethernet to a cable modem via ethernet.    There is only one ethernet port on the modem.   
    I want to keep the Mac connected via ethernet for speed.    Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
    If I need a router, what kind?
    Thanks.

    The modem connects to the WAN "O" port on an AirPort Extreme router.
    The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
    Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
    The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
    Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
    There are many other wireless modems offered by other manufacturers as well.

  • How to evolve a graph with only one loop

    1. how to continue to add new nodes to a graph with only one loop
    would like to use graph traversal like my previous post to traversal a binary tree, but this time, it can 
    loop forever, i mean it traverse all nodes in whole graph in the meanwhile it add new nodes too
    assume maximum number of joint is 2 or 3
    computing nightmare

    I just realised that you weren't talking about cyclic graphs (in the case of 1 cycle) here, but meant a single pass traverse and mutate.
    What you don't specify is how the new nodes are being supplied.  If they are supplied up front, then the loop will of course terminate once all the inputs are addressed, rather than going on forever.  If they are being supplied from time-to-time,
    then you need to have some sort of event-wait on input.  The traversal could have a move-next something like this
    If at end of tree with no new nodes, wait for input
    If at end of tree, with input, reset to start
    If at insertion point for new node at top of input queue, insert that
    Move to next node in tree
    This seems the sort of thing that would naturally be coded in a functional language as a tail recursion rather than an iteration.

  • How to daisy chain thunderbolt devices with only one port

    I am using a macbook pro with one thunderbolt port. Quite a few thunderbolt devices have only a single thunderbolt port (don't support daisy chaining).
    Does anyone know of a thuderbolt hub that adds additional thunderbolt ports?
    If such a product does not yet exist, is it at least technically possible?
    Thanks!

    (1) Thunderbolt does support daisy chaining up to 6 devices to the MBP's port (with some limitations). See
    <http://www.intel.com/content/www/us/en/io/thunderbolt/thunderbolt-technology-dev eloper.html>
    <http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh35952.html>

    <http://en.wikipedia.org/wiki/Thunderbolt_(interface)>
    (2) Note that daisy chain and hub are not the same. However, my understanding is that, in principle, a Thunderbolt hub is feasible. I'm not aware if such a device is already on the market. I guess that whether or not Thunderbolt hubs will be eventually available depends on the demand.

  • Create many SIA with only one installation issue

    Hi,
    I want create many CMS linked to corresponding SIA in one install.
    For sample, we have:
    PRG -->CMS 6400
    TST -->CMS 6500
    In the install, The SIA for PRG is autolmatically created.
    After this, I have created a new database in Mysql for TST.
    I have used command for create a new SIA :
    ./addnode.sh -name SIATST -siaport 6411 -cms boxi:6400 -user Administrator -password PRG
    I have launched the command :
    ./cmsdbsetup and respond the name of the new SIA --> SIATST
    I have 'updated' the datadase info and reinitialize the database. At this time, the CMS port is asked and I have respond 6500.
    Like explain at the end of the tool, I have launched the command:
    ./ccm.sh -updateobjects -cms boxi:6500
    After start the SIATST, I can connect to the CMS:6500 and all services is connected to the port 6500 (in the command line -ns boxi:6500).
    Unluckily, the <node> name SIATST is always present in SIAPRG (cms on 6400) but on failed to start.
    I have tried to remove this by command:
    ./removenode.sh -name SIAPRG -cms boxi:6400 -username Administrator -password PRG
    I have the error:
    Logging on to boxi:6400 as user Administrator with secEnterprise authentication...
    The SIA on this machine with the name SIATST doesn't exist in the cluster you are connected to.
    In the 'Server' tab in the CCM interface, I have always this node information and all services linked.
    It's possible to remove this SIATST on SIAPRG ?
    This procedure is good for wanted solution ?
    Thanks

    Why two primary that is 'coz geographically based server support and workstation. You can think it as a data center to data center split.
    That doesn't make sense and aren't valid reasons for 2012 (not that you can necessarily change it now).
    This line jumps out at me in the log file though: "An MP exists on this machine".
    That looks like the system you are installing on previously had an MP on it. I would delete the ccm namespace in WMI, cleanup all reference to ccm and Configuratin Manager from the registry, and then try again.

  • HT201269 me and my brother both are having iphone 4s we just want to exchange phones with each other also the whole data from one iphone to other is this possible or how can i do that with only one itunes?

    just want to move data between two iphones using one itunes.

    Make sure your computer iTunes is up to date. (iTunes 11.1.1)
    Now, do it one iPhone at a time; When you connect and select iPhone in computer iTunes sidebar (iTunes > View > Show Sidebar), what iPhone name do you see?
    iTunes is smart enough to tell the differences if each has a unique name.
    Point One checked.
    Right click on iPhone name in Sidebar and choose Backup.
    Do the same for the second iPhone.
    Make a copy of the backups in computer to another location (Just incase something gone wrong)
    Where iTunes backups are stored on computer http://support.apple.com/kb/HT4946
    Point 2 checked.

  • TS4020 how many devices can use one icloud account

    Is there a limit on to how many devices can use one icloud account

    *GE TAG - Don't you just love how people in forums answer their own question rather than the one being asked.
    Let me help those that have responded so far, and those still awaiting an answer.
    An account for iCloud does also include log-ins for the iOS App Store / Mac App Store / iTunes Desktop Application , but an iCloud account on any device iOS / Mac / PC does not have to match the App Store / iTunes account which certainly has its account login limitations per device as has been pointed out.
    What seems to be ommitted is if there is a limit to an iCloud account per X number of devices.
    In my estimation there appears to be no limitation for iCloud accounts per device. I say this only with the experience of having my own iCloud account on a MacBook Pro, Mac Mini, iMac, Apple TV Gen2, Apple TV Gen3, iPhone 5S, and an iPad Mini Gen 1.
    That is 7 separate devices. Never once have I been prompted about a limit when setting up my iCloud account (which constitues Contacts / Calendar / Notes / Reminders / Documents in the Cloud / Keychain / and Photo Stream and not purchased content through App / iTunes "stores" which do give such prompting upon authorizing your respective device for being able to use / sync said purchases)
    I've really only come to this realizatoin upon thinking this through after reading this thread. I was actually searching for this answer myself until now. If I'm wrong I will welcome a rebutal with proof.

  • HT204088 How how can I synch my ipod + iphone music to my new computer? I get the same error  "my ipod or iphone is synched with another itunes library.An Ipod can be synched with only one itunes library at a time. What would I like to do Erase and Synch

    How can I synch my ipod & iphone music (purchased from itunes on my old laptop) to my new laptop? I keep getting the same message on my itunes on my new laptop: " The ipod/Iphone is synched with another itunes library. An ipod/iphone can be synched with only one itunes library at a time. What would you like to do - Erase and Synch or Transfer Purchases?" What do I do?
    A couple of other items:
    1) I am guessing Apple does not keep a history of all my music purchases? As I did not have my entire library backed-up anywhere, and relying on the music I have on my ipod and my iphone as my only source of itunes music....I have lost over 500 songs!!!
    2) I used to have an Apple account under another account name, and since have switched to a new account name. Is there anyway to find the history of purchases from my old Apple account name and transfer these over to my new account name and onto my new laptop?
    I hope someone can help, I am having a very difficult time trying to obtain answers. Angie

    The iphone/ipod is NOT a storage/backup device.  Not maintaining a backup copy is a big mistake.
    You can transfer itunes purchases from your iphone/ipod to your computer:
    Authorize your computer for all accounts and then click  File>Transfer Purchases

  • How to make 1D Array but with only one element filled in Real Time

    Hi folks,
    here I am with another question. I want to implement an prediction discrete state space observer which is going to run on a CRIO real time target. I am going to do it just like in the example which comes with LV.
    I have some questions regarding the input and outputs which in the example those are "dummy".
    My model is a SISO model, but the function "Construct SS model" returns parameters (A,B,C,D Matrices) as 2D arrays, so once you connect the cluster model into the Discrete Observer model, it takes y and u as 1D arrays despite of the fact that there is a SISO model.
    I realized that the function I am using in the simulations, uses 1D arrays but with only one element filled:
    Does anyone knows how to implement such 1D arrays in Real Time? I guess the way to do it is preallocating one array of zeros of size 1, and then recirculating it through some SR, and replacing the element with my real input and output, but at the dummy.vi, they are using a simple "build array"
    function.

    Ok, I did it that way. But I am facing another problem right now...
    At some point the Discrete Observer return a NAN array, you will see the code in the code snippet?
    I get rid of that component by component, but the observer gets "stuck" in it. So my Control law is zero... but the state stimate is NAN.
    Also I am attaching the VI.
    I do not know why, since in the simulation program all runs well. any thoughts? Maybe the internal numeric precision of the State Space Model?
