Using 2nd optical bay for 5th system HDD?

Is it possible in the newly released Mac Pro to use the 2nd optical bay to house the system drive?
I want to stripe 4 x SATAs in the main enclosures on a RAID-5 for HD capture/playout with a CalDigit Hardware RAID card and have OS + apps on the 5th drive.
Is this possible? Has anyone done it with success?

I have two drives in the lower optical drive bay on a 2006 model.
MaxUpgrades has a kit for the older design, check and see if it is compatible. Sort of expensive kit. One drive should be easier.

  • 2x SSD as RAID-0 in 2nd optical bay, orig. must function... also RAM ?

    Hey all I know this is kind of a long post but I think it would help a lot of people out to get all of this information together in one spot so please help me figure this out. Thanks in advance.
    I am purchasing a 3.33GHz Hexcore MP, aside from processor stock from Apple. My plans are:
    Add 2x 4GB RAM to 2 of the 3 orig. 1GB chips, for a theoretical 10GB (for now) Is this feasible/advantageous?
    2x 50GB OWC Mercury Pro RE SSDs as RAID-0, boot volume, in 2nd optical bay. The catch is I'd really like to keep the std. optical drive functional in the first bay.
    4x 1TB 7200 drives in HD bays, two RAID-0 arrays, second as mirror of first.
    So here are my series of questions:
    1 - How can I hook up the 2 SSDs in the second bay as far as SATA/power are concerned. I do not want to hook them up externally and want a good fast pipeline for them, yet I do not want to disconnect the stock optical drive. Do I need any additional hardware/cables for an internal connection? I've also heard of a sort of hardware RAID enclosure that houses the two SSDs in the optical drive, occupying only one SATA/power connection and sharing it between the two of them. Does anyone know any specific products, and is the performance as good as two dedicated SATA connections?
    2 - using Disk Utility (or similar), can the second RAID-0 2TB HDD set mirror the first, like two RAID-0s nested in a fat RAID-1, or, in a pinch, is Time Machine or cloning the way to go for redundancy there? The idea here is to not buy the RAID card.
    3 - Can I partition a RAID-0 stripe or is that just a bad idea? The idea is to partition off space on the two RAID-0 HDD sets to mirror the SSD set (thus cloning the boot drive), plus a small partition for a windows VM. Any better ideas how to accomplish redundancy for the boot volume and isolation for a Bootcamp/VM partition?
    I know this is a lot and may seem rather amateurish, but I'd really appreciate some help here. I'd like to get this ball rolling! Thanks in advance for your replies!

    What are some of the 'other things' you refer to in this area that would yield a greater payback?
    • The biggest payback comes from having a separate System/Applications/Paging drive, by moving the Users folder off it completely.
    When you are running a program, it will read a User file, execute a little, then move into an area of the program or System that is not currently resident in RAM memory. This requires an access to the System Drive, to get a part of the program, a part of the System, or a part of a Paging file. Each access to the System/Applications/Paging area or drive takes longer because the arm was positioned to read the User file, and has to seek a long way to get to the System etc. area.
    Each time you access System stuff, this moves the arm away from your User input file, and the next User read will take longer because the drive arm has to be moved back to the User file.
    Separating System/Applications/Paging onto a separate drive from all User files speeds up everything you do.
    • If this drive is fast, that is better.
    Access time on a spinning disk varies varies, but it is commonly 10 to 20 milliseconds. It consists of seek time (time to move the arm to the track desired and verify that it has arrived at the proper track) and rotational latency (average time for the platter to spin around so that the required block is under the read/write head).
    At 7200 RPM, (120 spins/sec) one full spin takes 8.3 milliseconds, and half that amount is about 4.2 milliseconds. At 10,000 RPM, (166.6 spins/sec) one full spin takes only about 6 Milliseconds, and half that is only 3 milliseconds.
    A drive with a faster seek time, a higher RPM rate (which indirectly gives a faster transfer time), and a larger cache (approximately in that order) will speed up your System/Applications/Paging drive and make your Mac seem faster. For example, using a small 10,000 RPM Velociraptor instead of a 1TB 7200 RPM WD Black is snappier overall. It seeks faster and is spinning faster so the arm is positioned faster, the data get into read position faster (on average) and once reading has begun, the data are presented to the drive cache faster.
    Access time plus transfer time is usually dead time, in that little else can proceed until the data transfer is complete.
    • If this drive is a \[no seek time, no rotational latency, fast transfer rate] SSD, that is Much better.
    An SSD eliminate both seek time (positioning the arm to the track) and rotational latency (time waiting for the disc to spin around to the right block to be read) and substitutes a miniscule (by comparison) read time. Once reading has begun, a huge block of data is immediately available for transfer, so the effective data transfer rate is also much higher.
    • If this drive is an SSD Striped RAID, that is marginally better still, because it increases the effective transfer time.
    But the access time, the Big Boat-Anchor in this process, was almost eliminated by using the FIRST SSD. None of the typical seek-time and rotational latency gains of RAID-ing spinning disks are recovered by RAID-ing SSDs. The transfer rate is increased, often nearly doubled, but that is the smallest part of the delays caused by disk accessing.

  • MacPro RAID Card - working with SSDs in 2nd optical bay?

    I am planning to get a MP wit the Apple RAID card in order to configure 4 internal HDs as a RAID5. Does anyone have experience whether this setup would be compatible with one (or two) additional SSDs (boot drive) which will be connected via the 2nd optical bay.
    Does this work at all - I understand the RAID card changes from SATA to SAS ports. I am not interested to include the SSDs in the RAID setup but would like to know whether this would work at all or whether I should better plan without the RAID card.
    Thanks

  • SOLUTION:  DOES MY 2011 MACBOOK PRO HAVE 3G OR 6G IN OPTICAL BAY FOR SSD? *ANSWER*

    Hey guys, I just wanted to share the love and tell you I've finally spoken with Apple tech support (had to go through a handful of them to find the answer).. I have a [b][u]Late 2011 MacBook Pro (8,2) (MacBookPro8,2)[/b][/u], which was [B]*PURCHASED ON APRIL 4, 2012*[/B] and wanted to upgrade both the main HD and the optical bay/SuperDrive with Dual SSD's.. but saw so much conflicting info. on the internet about how some 2011 MacBook Pros only have 3G capabilities for the optical drive, where others (released later on) had 6G drive capabilities in BOTH the main drive and optical drive bay..
    so now I'm probably sure you're asking yourself...
    WHICH CONNECTOR DOES MY MACBOOK PRO SUPPORT FOR A [B]2ND SSD IN THE OPTICAL DRIVE/SUPERDRIVE BAY?[/B]
    3G (SATA-II) OR 6G (SATA-III)
    I literally had to call Apple a half a dozen times, spoke to 2 different managers, and then eventually got them to spill the beans.. The thing with Apple is that they beat around the bush big time when it comes to things like you personally replacing/upgrading components.. As soon as you bring up the connector for the optical bay, they start asking questions.. It eventually took me to 5th call to end up speaking with some chill dude who was able to pull up my "About My Mac" and interpret if I were part of the 2011-MacBook Pro releases which had the (6G main + 3G optical) or the group that had the (6G main + 6G optical).. Literally tried everywhere on the internet, but SO HAPPY to finally have a solid answer from Apple themselves..
    [b]My specific MacBook Pro Model:[/b]
    [u]MacBook Pro (8,2) - Late 2011 (purchased April 4, 2012) - 2.4GHz Intel Core i7 - 15"[/u]
    [B][U]*SOLUTION*[/B][/U]
    If you pull open your "About this Mac", click "More Info", and then "System Report", click on "SATA" on the left column, and then if your stats in those windows match the stats from the 2 screenshots I posted, then your Optical Drive Bay/SuperDrive is equipped and handle a 6G/SATA-III drive or SSD! I'm pretty sure that it doesn't matter at all what your "MacBookProX,x" number is, as long as you have #'s that match mine in those screenshots, you're good to go!
    ENJOY!

    Could you provide some rationale(s) behind it?  As far as I know, the mid 2010 Macbook Pro, the HDD is running via the SATA interface at running at 3.0 Gb/s, which is SATA II, and the Super-drive and/or the Optical drive, which is also running via SATA II interface, so I would assume the performance (i.e. primarily in speed) would be similar if not the same by placing the SSD drive in either one of the two places. 
    Also, wouldn't it be better by placing the SSD in the optical so the OEM HDD could be kept in the original main bay since it has the shock-sensing feature there?

  • Using an optical cable causes Bose system to shut off

    When I use an optical cable to play ATV2 through my Bose surround sound system, it turns the Bose system off after a few seconds. The Bose system works fine with the other components.

  • Any concerns with a 5th HDD in 2nd optical bay?

    I'm thinking of adding a fifth hard disk drive to my Mac Pro 2.8GHz Quad-Core (Mid 2010) "Nehalem" machine. I'll use if for storing audio sample libraries, some of which will be used in streaming playback. Are there any special concerns or considerations I need to accommodate?
    (I know I'll need an adapter. I'm planning to use OWC's Multi-Mount® adapter.)
    Thanks!

    Should not be a problem but I would install a temperature monitor utility just to keep an eye on things.  OWC is a fine choice.  Depending on just how large a drive you need you might want to also consider a SSD.  For those you could just let lay in there without mounting an adapter although adapters are sold for them too.
    Note, from what I read 3TB drives run relatively "hot" so you might want to avoid putting those in there.  Not sure about Western Digital 3TB "green" drives though.

  • Should I put the new SSD drive in main HDD bay or the Superdrive/Optical bay for a Mid-2010 Macbook Pro?

    Hello All,
    I'm considering getting a new SSD drive to add on to my Mid-2010 Macbook Pro (13 inches, unibody), and wondering which one of the following two options I should really adapt: 
    (1) Replace the original OEM hard drive in the main bay with the new SSD drive, and then remove the Superdrive (or the optical CD drive) and to be fitted into an external enclosure for using it externally in the future, and then relocate the original OEM hard drive into the Superdrive position, so both the new SSD (preferably for running the OS and system files) and the old OEM hard drive (for storing media and documents for example) could be used; and
    (2) Keep the original OEM hard drive in place in the main drive, and buy a superdrive/optical drive caddy to goes with the new SSD drive, and together place the new SSD drive fitted inside the caddy into the position of the Superdrive/Optical CD drive, and configure the boot preference to be booting from the Superdrive/Optical Drive (which is now the SSD drive with OS and system files);
    I've done some researches and some suggested that option (2) is better approach for at least two reason: (a) the MBP main drive come with some sort of shock proof sensor, so placing the original optical hard drive in the main is better than placing it in the super/optical drive where there is NO shock sensing feature provided, and placing SSD in the super/optical drive, one doesn't really have to worry so much about shocks; and (b) as during the process of shutting down the MBP, for optical hard drive, some power will sometimes needed to finally spin down the drive, but if such optical hard drive is place in the superdrive, the power maybe cut off right away when MBP shut down, which may cause issue to the optical hard drive in a long run as it never properly spin it down.
    Then the main concern is that, if I adapt option (2) above, placing SSD in the super/optical drive bay and install and running the OS from there, will it decrease the performance (i.e. speed, latency, and etc.) as if i was to put the new SSD in the main drive?
    Also, any suggestions with respect to Samsung 840 EVO vs. Samsung 850 EVO (250GB)? any well-rated HD caddy aside from OWC for moving the main HDD to optical CD bay? and perhaps an external enclosure for the Superdrive?  Thanks in advance for any comment and/or suggestion.

  • Which DVD burner for 2nd optical bay?

    Hi All,
    I really want to expand and get a faster, preferably dual layer DVD superdrive for my MDD. Considering I'm a total klutz and I want to do it myself, what is the best one to go with (ie. easy to install, no software issues etc). Any advice?
    Thanks in advance!
    Mel

    Hi, Melmac!
    Pioneer DVR-110 or DVR-111 and NEC ND3550A are favorites. Both are highly compatible with Tiger.
    If you can put up with multiple rebates, you can't beat the price on this NEC. (I'm using the same one in my QS 2002 Mac.)
    Here's a link to video install instructions. The process is quite simple. You could just add the new one and run two in the MDD, if you want...

  • Does Satellite L855-10X supports an bay for a second HDD drive

    Does L855-10X have one empty slot to add SSD disk, without removing actual HDD?

    Im not L855 owner so I cannot say it for sure but from my experience such upgrade is not always possible
    Here in the forum you could read some threads about similar themes and mostly this did not work.
    The notebooks like Portege M400, M700, M750, Tecra M9,Tcera S1, Tecra S2, Tecra S3, Tecra S4, Tecra M1, M2 or M3 supports such select bay but never read about compatibility on Satellite unit.
    So from my knowledge you would get an BIOS problem. The 2nd HDD would not be recognized or in worst case the notebook would not power On.

  • Should I use Sub-Equipment Hierarchy for sub-systems (first post)?

    I am 2 months into the maintenance manager role for a fleet of Locomotives and it has been decided to use SAP PM by senior management based on a separate business arm requirements.
    I believe for this to be successful the first step is to get the structure right so that data is collected in the most logical manner.
    I intend to use SAP to schedule all maintenance tasks based on measuring points and dates of previous work orders, capture system and sub-system failure history, capture costs and parts usage and trend performance of subsystems based on their own and system level measuring points.
    I have been told that all locomotives are assigned to a single functional location within the business model. The individual locomotives themselves are assigned as separate pieces of equipment in this functional location.
    Within the individual locomotives there are a series of subsystems that have associated maintenance requirements based on time and usage and they are serial number tracked. These items are exchanged between the locomotives and the warehouse upon failure, upgrade or overhaul and include:
    AC traction Motors
    Wheelsets
    Diesel Engine
    Main Generator
    Auxiliary Generator
    Dynostarter
    Gearbox
    Compressors
    Traction motor blowers (Fans)
    Radiator fans and AC radiator fan motors
    Is it logical to put these as sub-equipment within an Equipment Hierarchy with the Locomotive being the superior equipment?
    Should notifications regarding their failure be assigned to the Superior Equipment (Locomotive) or the Sub-Equipment and what are the implications of each? If assigned to sub-systems can I still report on system reliability by "rolling up" the failures?
    Do the measuring points (e.g. kilometres) assigned to the Superior Equipment (Locomotive) accumulate to the Sub-Equipment automatically and does installation and removal from different Locomotives with different kilometres affect this? For example a traction motor in Locomotive 001 is installed from 100,000 to 360,000 locomotive kilometres and then it is installed in Locomotive 002 from 300,000 to the current 340,000 locomotive kilometres. Does SAP accumulate 300,000 kilometres of life to the traction motor sub system based on its superior equipment's measuring points?
    I have many more questions to come that I will most likely solve through experimentation and future questions, but in order to hit the ground running I would appreciate your feedback if any of you have similar experiences.
    Thanks in advance
    Glenn Sanders

    In SAP, you can define "N" no. of hierarchies for Functional Location & Equipment.
    But in the reporting, you can get the costs at Functional Location level & Equipment level at next. Its not possible to have Sub Functional Location level or Sub Equipment Level.
    Also, you have mentioned that you will interchange the Sub components between Locomotives. Also, you want to maintain those using Serial Numbers. You can define these Sub Components as Assemblies with Serial Numbers so that Equipment can be created for those combinations.
    To maintain Measuring Point for Sub Components, Equipment should be created. In SAP, you have the option to transfer the Measuring Points from One Equipment (Superior Equipment) to another Equipment (Sub Equipment).
    While interchanging the Sub Component from One Locomotive to another Locomotive, without Measurement Reading Transfer, you can dismantle & install the same.

  • Can EBS E-Tax be used as Tax Engine For External Systems

    Dear E-Tax Gurus,
    I have a question regarding to e-tax engine in R12. Assuming we have EBS R12 and another system that is not EBS, but both has same customer base and same product base (so customer and product which we get is exactly same from that system). Is there a public nor private API that calculates tax for given item, customer etc?
    What could be the consequences if we create a wrapper API that uses some internal API if there is available?
    Thanks for replies.
    Bilal

    To answer to your question, EBTax cannot be used on non-EBS. EBTax is an integral part of financials suite, especially with AR.

  • 2nd Optical-Drive for Early 2008 Mac Pro: Suggestions Required

    I am hoping to add a second optical-drive to my Early 2008 Mac Pro.  I notice that there are various SATA ones available for Early 2009 Mac Pro's onwards (e.g. the LG GH24NS90) but according to OWC (Other World Computing) these ones are apparently unsuitable for earlier Mac Pro's.
    The current optical-drive in my Mac Pro is a Sony AD-7170A.
    Can anyone suggest a suitable optical-drive that is still available as new (preferably available in the UK).
    Thanks,
    Yan Lee

    The SATA optical drives will work fine in a 2008 Mac Pro. I just installed this model:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16827136259
    I already have a Blu-Ray SATA drive in my other tray, so I've done this a couple of times now.
    You have to run a SATA data cable through to one of the two ports on the motherboard - it involves removing the first two drive trays and the front fan. The cable goes up behind the top left corner of the compartment, together with the black cables feeding the optical ATA connectors. You CAN use an L-shaped (90 or 270 degree) SATA cable, but I've found that a regular straight cable works OK too - it is a tight fit behind the fan, but it should fit. The trouble with the L-shape is that it blocks the other SATA port. You can also look for low-profile SATA cables, which have slightly smaller heads.
    You'll also need a molex-to-SATA power adaptor. Don't forget to remove the front bezel from the drive - I do this by attaching everything to power, don't slide the optical enclosure back into the space yet, power up the computer, eject the drive using its eject button, and then slide the bezel up and off. You can then slide the enclosure into the space. Turn the computer off to put the fan and drives back in.

  • Backing up system that's using 2 hard drives for main system????

    I use a Raptor 74gb as my boot drive, and another internal 250gb as my "Home" folder
    i'm selling my powermac, so what would be the best way to backed that up so i can transfer it all together on a single HD (replacing my powermac with new macbook pro)???????????????????

    If I understand correctly, your Home folder is linked to the Users folder on the Raptor. If so, use something like Carbon Copy Cloner, SuperDuper!, etc. to make a bootable clone onto a bootable, external FireWire HD of what's on the Raptor. Then, after eliminating whatever you used for the link (symbolic link or alias), drag and drop your Home folder to the appropriate place on the clone, Boot into the clone to ensure it works and acts like the original. Once that's done, erase both internal HDs and use the Restore disk to restore the original software.

  • Using the Log Viewer for two systems on same host

    We have two Portal systems installed on the same host server.  The log viewer only identifies and displays the log files from one of the systems (A).  This is the case even though I started the log viewer while logged on as the <sid>adm for system (B).
    In the configuration of the Log Viewer, I do not see an option to have it add another "system" to the local host.
    How can I configure the log viewer to display logs from both systems installed on the same host?
    Thanks,
    Bob

    Bob,
    with the port you can distinguis between the servers. both portals should have unique ports on the same server.
    for you relevant is the P4-port.
    these settings work for remote servers:
    Name: <SID>
    Host name: <hostname of server>
    Port: <P4 Port, normally 5<SysNr>04>, you can check this at: http://<host>:<port>/sap/monitoring/SystemInfo under the Dispatcher infos
    Connection: J2EE
    User: <admin user>

  • AppleScript to open 2nd optical bay?

    Yep, I know that with an Apple keyboard it’s Option-Eject. I’m using a Logitech diNovo Mac Edition keyboard and that combo opens the primary drawer only.
    I know that I can do this by opening Disk Utility, choosing the drive, and clicking the “Open” button, but I'd prefer to have a script or other alternative. Any help would be appreciated.

    Using Automator's Run Shell Script action, enter this text:
    drutil -drive # tray eject
    ...where "#" is the number of the device. You can find out the number of the desired device by opening Terminal and entering drutil list.
