Dual Channel Ultra320 SCSI PCI-X Card

I'm connecting a SCSI backup tape drive to my Mac Pro. The tape drive instructions state that I'll need a SCSI host bus adapter. Will the Dual Channel Ultra320 SCSI PCI-X card do the job or is a host bus adapter something different?

Are you sold on using tape? there is only one ATTO UL5D and you need PCI Express.
How about $99 for UltraSCSI 50-pin vs LVD Firewire to SCSI from Ratoc.

  • Is ATTO 0096-PCBX-002 Ultra320 SCSI Controller Card For Apple PowerMac G5 pci-x  ??

    is ATTO 0096-PCBX-002 Ultra320 SCSI Controller Card For Apple PowerMac G5 pci-x  ??

    Is this an OEM card? ATTO web site does not list such a model.
    Otherwise, you'll be better off with a ExpressPCI UL4D or UL4S. I have run a UL4D in my G4 MDD for years with absolutely no problem. You could get one from ebay for cheap.

  • Apple Dual-Channel 4Gb Fibre Channel PCI Express - Protocol?

    I need to know what kind of protocol that this board Apple Dual-Channel 4Gb Fibre Channel PCI Express work?
    Do not know if it is SCSI or Ethernet protocol or some other protocol ...
    Someone please tell me know?
    THANK YOU

    If anyone is interested, I found out that the Exabyte tape libraries don't like the Apple Fibre card. I switched to an Atto Fibre card and the connection to my Magnum 448 seems to be working great.

  • Dual ultra320 scsi controller

    Hi all
    I m trying to install new dual ultra320 scsi controller on Sun Fire c20z Server. But there is an error message
    ERROR: EXPANSION ROM NOT INITALIZED
    PCI MASS STORAGE CONTROLLER IN SLOT 02 BUS 03 DEVICE 01 FUNCTION 0.0
    Pls help me to fix this Problem

    Sorry rakman2, but your suggestions will not work with that system.
    A Sun V20z is Intel Xeon based.
    No OBP, and therefore no OBP commands or utilities (such as <i>probe</i>).
    Let's just wait for <i>hero</i> to provide more information.
    Edit:
    Corrected a typo and noticed that it has been three months.
    The original poster has not returned.
    ... and an error about a ROM on a peripheral usually means unqualified 3rd party hardware.

  • Two dual-channel scsi controllers on S10 8/07 x86?

    I'm attempting an install of Solaris 10 8/07 x86 on a server with four channels of scsi devices. The problem is that the install procedure only recognises the controller on the motherboard, and not the additional controller on the pci bus with the boot disk.
    The motherboard is a Supermicro X7DB8+ with integrated Adaptec AIC-7902 (dual U320), and the additional controller is an Adaptec 39320A (dual U320) installed in PCI-X slot 3. The scsi bios gives the following display:
    AIC-7902 A at slot 07 04:02:00
    AIC-7902 B at slot 07 04:02:01
    39320A A at slot 03 07:01:00
    39320A B at slot 03 07:01:01
    The controller master is set to the 39320A, and the system disk (id 0 on 39320A channel A) is enabled as a bootable device on the motherboard bios. Everything appears fine at both the scsi and motherboard bios levels - all drives are visible and all diagnostics work as expected.
    However, trying all permutations and combinations I can think of, the S10 installation routine persists in only recognising the drives on AIC-7902 channels A and B (as c0xxxxxx and c1xxxxxx). I cannot see the drives on the 39320A nor enable any of them as a boot disk for installation as desired.
    Any one with any ideas? I'm stumped now.

    Thanks for the tip! I was sure I disabled HostRaid, but apparently it was not disabled on the 39320A. Everything works as expected now.
    Regards,
    Adam.

  • I have a PCI-FBUS card (dual port), can't connect over 60 devices to it?

    I connect to various Fieldbus devices (all from the same manufacturer and same type as we are an OEM) that I am testing (I have 80 in my test system).  I have the dual port PCI Fieldbus card and am running communication manager 3.2 on Windows XP with service pack 2.  As part of my pretest (getting the devices on the bus and assigning them a unique address) I connect to a device and change its address to 20 and power off the device to have it drop off the bus then relay in the next device and connect to it and change the address to 21 etc etc---this process makes it easiest for me as then all I have to do is connect to the only device on the bus and know that it is the device I am interested in assigning to it a new unique address as the others are not on the bus.  I am able to get 30 devices per port (60 devices total since I have a dual port card).  After the 30th device is connected, albeit no devices show up on the bus since they are all powered off, I relay in my 31st device but I can't connect to it on a given port (at this point I have 30 devices that were connected to each port but are now powered off).  I have the card configured to operate within the address range of 16-102 for both ports.
    What is the limit of the number of devices that can be connected to a given port?  What would be the recommended way of connected say 80 devices to a PCI card (40 per port).  For my application, after the so called pretest is complete, I do have to have up to 8 devices powered on at the same time (4 per port) so that is why I want to keep the addresses unique per device.  By the way I know this is not a physical connection issue with my station as I can connect to all devices when I limit my test to 60 devices (i.e. I can do the first 60 or the last 60 so the wiring etc is good as well as my assigned address space/parameters for the NI card).

    Hello Jim,
    In NI-FBUS, the max number of devices that can be connected to a segment (port) at one same time is 32. This value is defined by FF specification.
    Please try the following method.
    After connecting the 30th device, restart NI-FBUS Communications Manager (CM), then connect the 31th device. Check whether the problem still occurs.

  • G5 Dual Core 10.4 - Finally a PCIe eSATA card that works!

    Happy Holidays!
    I recently posted a few queries/complaints about FirmTek's PCIe cards used in an older Dual Core 2.0. Unfortunately my personal experience has not been a good one. Poor communication and initial refusal of RMA; the list is lengthy. After months of tedious thorough testing, I can only conclude the drivers on their web site, are incompatible with 10.4.11. But thanx to OWC, and DAT Optic, I finally found a PCIe eSATA card that works. In fact I'm using a DAT Optic 2 port card and 4 port card in total harmony with each other.
    In my opinion, the SeriTek 2ME4-E-4 design emphasis was probably geared more toward use in a Mac Pro with 10.5 and above. After two system formats, and the failure of two different FirmTek PCIe cards, that was enough for me.
    Final success came with; http://eshop.macsales.com/item/DAT+Optic/ESATAPCIE21B/ (and) http://eshop.macsales.com/item/DAT%20Optic/ESATAPCIE8/
    One BIG advantage with DAT Optic are the numerous readily available drivers directly from the Silicon Image web site. And their tech support is first class.
    All of this is good news for users of older Power Mac G5's.
    Enjoy!
    Mike

    Hi Chris
    Whatever the situation was with 10.4.10, or 10.4.11, I had to conclude that FirmTek's drivers were not doing the job for 10.4.11 - The condescending technician was basically ignoring my remark that this card just doesn't work with my set up. Neither could their 2 port card work.
    I had to argue my point repeatedly, (shouldn't have to do that).
    In any event, I'm rolling pretty good with these 2 bay OWC clearance eSATA enclosures, (got 4 of them). No bridge, just good ole eSATA connections. Sure took long enough to get to this place.
    Happy Holidays

  • 64 channel 1450 Hz data logging with PCI-6033E card, on-line averaging and viewing the raw and averaged signal in CWGraphs.

    I'm acquiring 64 channels at sampling rate of about 1450kHz continuously and showing the data second by second in a CWGraph. Now, I would like to add an on-line averaging for all of those 64 channels and show it in another CWGraph. The averaging should occur with respect of external trigger and the sample should consist of about 100ms prestimulus and 500ms poststimulus period. Has anybody been handling this sort of things? How it's solved with ComponentWorks and Visual Basic?
    I'm using double Pentium 700MHz processors and NI-DAQ PCI-6033E card.

    1. To get started with external triggering check out the examples in the Triggering folder that install with CW under MeasurementStudio\VB\Samples\DAQ\Triggering.
    2. Create a prestimulus buffer that always contains the latest 100 ms of data. Just modify the CWAI1_AcquiredData event to transfer ScaledData (the data acquired) to your prestimulus buffer. See how there will always be a prestimulus buffer of data regardless of trigger state?
    3. On the trigger, you can use the same CWAI1_AcquiredData event to route the data into poststimulus buffer and average the 2.
    I see something like this:
    if no trigger
    100 ms of data to prestimulus buffer
    if trigger
    500 ms of data to poststimulus buffer
    averaging and display function
    reset trigger and buffers
    good luck

  • K9N PLATINUM(NON SLI) DUAL CHANNEL MODE PROBLEM

    hi
    put a new system together with the following specs:
    amd am2 3800+(2ghz)
    k9n platinum 1.20 bios
    2x512 kingston ddr2(667mhz)
    pci video(yes not pci-e)have not decided which vid card to get yet.

    seagate 300gb ide  7200/16 meg cache windows xp-pro sp2 with all updates.
    not overclocking or even trying to.
    no sata drives connected.
    has never failed to post,boot windows and no lockups or blue screens.
    ok,i am trying to get the memory to work in dual mode.
    everytime i put the memory in the dual mode slots,the cpu clocks down to 1ghz instead of 2ghz.
    verified by bios,windows and cpu-id
    i have tried different memory(both ddr2 533 and 667)667 installed now.
    also never had any install problems with windows and everything runs fine until i tried dual mode.
    after the cpu clocks down to 1ghz,the only way to get it back to normal is a bios reset( load defaults
    or press red button).
    if i leave the memory as single channel then i have no issues.
    also cpu-id says the chipset for my board is nforce 550,i thought k9n platinum had 570 nforce chipset?
    this might just be a problem with cpu-id though.
    any thoughts on the cpu down clock problem in dual channel mode?
    thanks,jeff

    1 assume you can get into BIOS with 1 stick only?
    Go into the BIOS and manually set the timings and voltage to what your memory manufacturer recommends. Use a 2T command rate and see if it works.
    Try both "sets" of dual channel slots, i.e. the two left slots or the two right slots.

  • Single Channel Dual Channel Question, K8N Neo4 Platinum

    Just putting together a machine for the Daughter. Using MSI K8N Neo4 Platinum board 7125-010, MSI NX6600GT PCIE 128 Video card with AMD64 3700 CPU SD and a 1 GB stick of Crucial dual sided memory, CT12864Z40B, DDR 400 3200. The rest of my parts arrived and just got it all together and booted into the Bios. The boot screen tells me the memory is DDR Single Cannel, 64 bit running at 3-3-8-3 and 2T timings. I have been into the Bios setup, but had let the memory boot at Auto settings. Is what I am seeing on this screen OK because there is only one stick of memory installed? Or am I just confused as normal? I was thinking it should read Dual Channel, but I am hoping that is just my backwards thinking at times. I wish all a very Merry Christmas and a Happy New Year. Thanks in advance for the guidance.
    Pop's

    JayBee; Thank you very much for the quick response. The Daughter decided to go with the 1GB stick to begin with so as to possibly add another 1GB stick later. I don't think she will need it myself, judging by her computer use. She does no gaming or multi-tasking, so there probably will be no need to add more memory in the future. I was just wondering if there is any noticable performance hit by using a single stick vs a pair of matched 512's?? I used the same MB as in my sig, but noticed the new one has an upgraded BIOS. I hope it is an improvement, because I have yet had no problems with my machine which has the V1.6 BIOS. This new one which is about 2 months newer than mine has a BIOS V1.A in the bios screen. At bootup it is identified as ( 6A61FM49C-OO ) what ever that means. I read the forum daily and have noticed you are very active and consice in helping folks out. I very much appreciate your time and effort that you give freely. Hope you have a very safe and happy holiday season and SANTA is very good to you. I think we as a group need to get SANTA up to speed on gift giving in the computer upgrade department.

  • Dual channel memory mixing on a K8T Neo2

    Hey all,
    I have a K8T Neo2, Winchester core 3000+ and had it running with 2 TwinMOS 512 MB-DDR400 sticks in dual-channel mode. Recently I decided to add RAM, but to invest in a more solid brand. So I bought a Corsair TWINX1024-3200C2 set and plugged it in. AFAIK the right combination in the board would be the have one set in slots 1 & 3 and the other set in 2 & 4. So far the board will only post with the Corsairs in 1 & 3 (and not with the Twinnies there). But if it posts, the clock is set to 333 MHz (which is an issue of the Winchester core I understood), but more importantly the system becomes unstable: reboots etc. Even stranger is the fact that sometimes after POST I get 8 beeps from the BIOS, which suggests that the Video RAM or framebuffer is defective. Is this somehow related to the RAM I installed? Is the framebuffer mapped to the RAM at bootup for example?
    I did try to change the command rate to 2T, didn't seem to help. Bios version is 3.3 by the way. Thanks for any help.
    Oh maybe the vid card specs are also relevant: Sapphire Radeon 9800 pro with 128mb. Power supply is Tagan 580W so unlikely to be the problem

    Quote from: Tiresmoke on 03-November-05, 23:54:30
    Have you tested each stick of RAM with Memtest86 yet? You may have a bad stick. You also may want to try the new set in a different socket sety. Another words if it was in 2/4 then try it in 1/3. If the timings are different on the two sets try setting to the slowest settings of the two. You may have to exchange the set for the twin to the old set just to make it work as mixing RAM rarely works well.
    Good idea on the memtesting, I'll do that tonight. I was afraid that the mixing wouldn't work well, but I thought at least if for each channel I used the same pair it wouldn't matter. Practice might indeed prove that as being a wrong assumption

    With the last BIOS, it states that 4GB modules may be possible, but looking at the memory test report http://www.msi.com/file/test_report/TR10_1393.pdf  it seems this was only done for DDR2 modules, as these are the only ones reflecting this.
    Suggest you check with MSI technical if the BIOS should accommodate DDR3 4GB modules as well.  >>How to contact MSI.<<
    Do a CMOS clear, then once in the BIOS, set your DRAM ratio so that the DRAM is at 1066. See if that works.

  • How to get counter values from pci 6221 card?

    Hii
     I am using PCI 6221 card .. In that i am using the ctr o .. In my application i am using Linear encoder to measure the Lift movement.. so from software how to access the counter values i.e how much mm it moves... 

    Measure Angular Position.vi in the LabVIEW examples will be a good starting point. Adapt it to Linear Encoder by clicking on the selector below DAQmx Create Channel.vi.
    You can also create a corresponding DAQmx Global Channel (or task) in MAX and then use it in your code.

  • Neo2 platinum Encountering Stability Problems /w dual channel memory

    Hello,
    Recently I built my first computer ever, see bottom.  After getting windows installed I then had problems with installing other programs and general stability issues.  I tried reinstalling windows and after the reinstall I got the same problems.
    Something to do with the instability is when I start it up, and go into BIOS, it states my Athlon 64 3500+ as running at 2211, a half percent overclock.  Also, even though I have the FSB set as 200mhz, when I go into CoreCenter on windows it states the FSB as being set 201mhz.  In the nVidia system utility, it states my memory as running at 402mhz, and I had to crank that down to 400mhz to get stability, it allowed my to install programs without error, but there were still stability problems like crashes(blue screen, the computer just plain restarting without notice).  I took out one of my memory cards, both of them work alone though, I've ran memory test utilities.  That had a good effect and the computer runs fairly stable, but I still have problems, and I want to be able to take advantage of dual channel.  I'm running my memory on auto and it's using the times of 2-3-3-6-2T.
    Another problem I'm experiencing is the AC97 audio not being detected and loaded by windows, it will say I have no audio device, and the speaker will not show up in the notification area in the bottom right-hand corner.  This happens inconsistantly.
                               -Thank You

    hi bknoll,
    welcome to the forum.
    1) i wouldn't worry overmuch at the 201 issue.
    2) Quote
    I've ran memory test utilities. That had a good effect and the computer runs fairly stable, but I still have problems
    which test utilities did you use, Don't quiet understand  Quote
    had a good effect and the computer runs fairly stable
    3) It may be worth checking the Mushkin site or any documentation you have to verify that the auto settings agree with the quoted settings for the modules. It's not unkown for errors to occur when the memory controller on the CPU to misinterpret the SPD chip setting on your sticks - this is where the auto settings come from. Some memory like certain corsair modules need to run at different settings on AMD64, thus auto timings must be overidden,
    4) Have you installed the Realtek drivers from the CD, & enabled onboard sound in Bios. When these are done normally there's the MSI Sound Effect manager in control panel. you just need to set your speaker config in the Windows Sounds & Audio Devices.
    5) Usual question What power supply are you using as been underpowered on the 12v rail in particular can be the cause of crashes,

  • Maximum number of PCI-6602 cards in 1 computer?

    Is it possible to have 4 PCI-6602 cards in 1 computer?
    Are there any DMA channels or IRQ limitations we need
    to worry about?
    Our computer will have 1 graphics card in the AGP slot,
    possibly a PCI NIC ethernet card and possibly a PCI
    based sound card. It will also have an IDE controller
    with 2 hard drives and 1 CDRW.
    The PCI-6602 manual seems to imply that if you are
    using more than 3 counter channels that you must
    use the slower Interrupt based transfer mode which
    has a maximum transfer rate specified as 2000
    Reading/second. If there are 4 PCI-6602 boards in
    the same computer and all 8 of the channels are
    used on each board does that mean the total
    transfer rate is still 2000 Readings/sec? Or
    wo
    uld the total transfer rate be 8000 Readings/Sec
    since there are 4 PCI-6602's (2000 Readings/Sec
    for each of the 4 PCI-6602's)?

    Hello;
    The only concern you need to have is the number of IRQs available. As far as DMA channels, as the PCI bus itself has only 3 DMA channels available, all the devices that use DMA will share those 3 channels. But, as IRQs can't be shared, the number of counters you will be able to use will be the exact number of available IRQs you still have on your machine.
    As far as transfer rate, the maximum transfer rate will be 2000 Readings/sec, regardless the number of counters you are using.
    Hope this helps.
