Raid 1 advice for externals.

I am looking to get a Raid1 external set up and these are the three that I am considering. Any thoughts or current users of these products would be more than helpful. I like the speed of the Sata but also like using the FW becuase many times I use my laptop to edit as well. Thanks in advance.

Go to www.aja.com and look in the DOWNLOADS section for the AJA Kona System Test. This can tell you what the read/write speeds are.
FW800 with one drive (so two drive in a RAID one configuration will get you the same results) can handle one stream of 8-bit uncompressed. Two drives at Raid 0 will get you 3 streams of 8-bit, and one of 10-bit. So what you have is possible.

  • RAID Disk Layout advice for Hybrid OLTP/Batch app

    I was hoping for some advice from the community on my disk layout for a proposed upgrade to our Oracle setup (Windows 2003, JDE+Oracle9i, primarily OLTP/Batch extracts). Focusing purely from a hardware perspective, we're being given 14 disks to work with. I had initially thought that it was a lot, but when I start putting the spindles into RAID configurations, it doesn't give me a lot of room.<BR>
    <BR>
    <B>2 Disks RAID 1 (mirrored) for OS, App and Oracle Binaries<BR>
    2 Disks RAID 1 (mirrored) for 1 set of online redo log files<BR>
    2 Disks RAID 1 (mirrored) for archive log files<BR>
    8 Disks RAID 10 (mirrored and Striped) for all data/index/undo/temp files.<BR>
    ----------------------------------------------------------------------------------------------------------<BR>
    14 total disks</B><BR>
    <BR>
    My question is -- where would I put the other set of multiplexed redo log files? Hardware mirroring gives me fault tolerance against media corruption, but doesn't protect me against accidental deletion of the logs. I don't want to put the 2nd set on the OS drive because it's mixing sequential (100% read / write) and random access (OS paging, binaries).<BR>
    <BR>
    I also wanted to better understand how the LGWR and ARC0 processes work. From the Oracle Perf Tuning Guide, the LWGR writes to one member at a time, so it pays to have alternating log groups on 4 disks. We believe the ARC0 process reads only the primary member of the disk, yet the figure 8-1 in the above document shows an arrow from ARC# to both redo members. So how does it really behave? Does it actually read from one or both members? If it only ever writes to the second set and never reads it, where would I put it? Could I even put the second set of online redo's into the data/index/undo/temp set of disks?<BR>
    <BR>
    I've already been perusing the various AskTom articles and read the Oracle whitepapers (#1and #2) on S.A.M.E. (stripe and mirror everything), and they all make some good suggestions -- it's just with this few disks, I find myself having to make compromises. Any help or suggestions on a better layout would be appreciated.

    Hello Carl,
    You have to implement this SAP Note - 1313075 to meet your purpose.
    Create variant under this program - RFFOAVIS_FPAYM and assign the same in printjob tab in F110.Also you have to maintain the sender mail id details in FSAP T code and receiver mail id details in the concern vendor master data.
    I hope it helps else revert us with your query.
    Thanks & Regards,

    There should be no issues. Its designed to work like that.  You don't change Apple IDs just because you get a new device.

    Unlikely. But nothing is impossible.   Though I don;t see how that would happen. As long as both are signed into the Same Apple ID / iCloud Account they will be N'Sync. (Bad Joke)

    If I get a message or buy an app or take a photo on the iPhone 5, how do I get those things onto the iPhone 6?
    If you buy an App, you have 2 ways to get it to the iPhone6: If Automatic Downloads is enabled in Settings->iTunes & App Store, it will automatically download to the iPhone 6 when you buy it on the 5 and vice versa if you buy it on the 6, it will download to the 5.
    Alternatively, you can simply go to the App Store App->Updates->Purchased and look for the App there and download it. Purchased Apps will not require payment again. i.e They'll be free to download to the iPhone 6 once purchased.
    SMS Messages will sync over using Continuity as long as they are on the same Wifi network. Otherwise, restoring the iPhone 5 backup to the iPhone 6 will transfer all messages received up until the backup was made onto the iPhone 6.
    Images, can be transferred either through Photo Stream
    My Photo Stream FAQ - Apple Support
    Or any Cloud service you want such as Dropbox, or One Drive.
    mannyace wrote:
    Also, something i forgot to ask initially: Should I update the iPhone 5 to iOS 8 first or does that not matter?
    If you want the Continuity features as explained above you need to update the iPhone 5 to iOS 8. Otherwise its not all that important.

  • Multiple libraries, Pbook/Pmac, advice for management & updating please.

    Hi Everyone,
    I travel frequently, and am looking for suggestions to keep all my iPhoto libraries up to date. I currently have a g5, Powerbook, and Mini.
    I just upgraded to iPhoto 6 and I have several thousand photos on my Dual g5. I just came back with 1000 more from my diving trip. The problem is, they are on my Powerbook, and taking up alot of space on the relatively small hard drive. I managed to work through the rough upgrade from 5 to 6, and now I need some more help...
    1) What is your advice for managing multiple libraries of photos.
    2) What is the best way to transfer the iphoto pics (and movies) to my desktop, which of course has the larger storage capacity, after travelling...
    Thanks,

    Jason:
    There are several different approaches to what you want to do. Let me just throw out a couple that I'm familiar with.
    To get the new photos from your PB to your G5 and maintain any keywords, and other organization effort you put into them, you'll need the paid version of iPhoto Library Manager. It will allow you to merge libraries or copy between libraries and maintain the metadata, etc. That's the only way currently available to move photos from one library to another and keep the roll, keywords, comments, etc. with those photos. You can connect the two Macs with one in the Target Mode, probably your PB, and then run iPLM to move the photos to the G5 library.
    Now there is a way to have a library on your PB that reflects the one on your G5 but is only a fraction of the size. That's to have an alias based library on your PB that uses the Originals folder as its source of source files. (My 25,600 files, 27G, are represented by an iPhoto Library folder of only 1.75G). When the PB is not connected with the G5, say with a LAN, it will have limited capabilities which are in part: you'll only be able to view the thumbnail files, be able to add comments, create, delete or move albums around, add keywords (but with some hassle-but it can be done). You can't do anything that requires moving thumbnails around, work with books, slideshows or calendars. Once the two computers are networked together again the library will act as normal.
    Now while on the road you can have a "normal" library to import new full sized files, keyword them, add comments, etc. and then transfer to the G5 library. Once in the G5 library they will be represented in a roll(s) and corresponding folder in the Originals folder. You then fire up the "alias" library, and import those new folders in the G5 Originals folder.
    It may be a lot of work but it may be one way of doing it.
    I've not done any of the "sharing" with iPhoto so don't know if that's another possible candidate for transferring.
    P.S. FWIW I've created this workflow for converting from a conventional library to an alias based one.

  • Advice for real performanc​e of LV8.5 operate in the XP and Vista

    Hi all
    My company had purchased new computers for LabVIEW programming purpose.
    We may install the LV8.5 in these computers but OS are not decided yet. Also, we have the current PC is only XP licensed
    Therefore, can anyone give the advice for the real performance advantage of using :
    LV8.5 with Vista over LV8.5 with XP
    LV8.5 with Vista over LV7.1 with XP
    LV7.1 with Vista over LV7.1 with XP
    New computers detail:
    Intel(R) Pentium(R)Dual-Core processor E2160
    BCH-P111 -1.80GHz, 1MB L2 cache, 800MHz FSB
    2GB RAM
    Thanks
    Best Regards
    Steve So

    The biggest issue I have seen with 8.5 Vista vs. XP is that if you leave Vista in the standard theme, the fonts have changed.  I designed several front panels to have them be out of whack with XP.  So if you are going to be using code across platforms, you need to keep in mind they will look different unless you use the XP theme in Vista, or customize your fonts to make sure they remain the same between the systems.  The dialog font is a different size (13 on Vista vs. 11 on XP), and a different font (can't remember the difference).  That was the big one I noticed.
    8.5 over 7.1 is mostly going to be the learning curve to learn the new features.  Overall, I have appreciated the changes, but there are some things (mostly development related) that I have seen run a little slower in 8.5 than in 7.1, but have not noticed any runtime issues as of yet.  One big change between the versions is application building, which is more complex in 8+.  I do appreciate the new features, though, but NIs project still hasn't rubbed me the right way yet.
    NI doesn't support LV 7.1 with Vista.  I have used it and haven't seen any problems, but that doesn't mean one won't pop up.  If you're going to stay with 7.1, you better stay with XP.  8.5 is the first version NIs supports as Vista compatible.  You will also have to use a relatively new set of device drivers, so if you have old hardware you are trying to use in your new system, make sure it is cimpatible with the latest drivers.
    I have actually had more issues with other hardware drivers and software packages than I have with LabVIEW.  TestStand is not yet supported in Vista, and i found out the hard way, one of the ways it is incompatible and had to move back to XP for devlopment.

  • Creation of ACH pmt advice for EU C.Cd (PMW activated)

    Hi experts,
    I'm a little at loss with my 1st dealings with the payment medium workbench. I got a requirement to setup payment advice a EU company code that currently sends out ACH payments without advice.
    Currently In FBZP,
    1- The EU CCd is a paying company and the form is the same Z_REMITT_S used for the client's US company.
    2- The ACH payment method is defined for the country. The medium is the payment medium workbench and the format is Z_SEPA_CT.
         The US company uses the classic workbench and program RFFOUS_T for ACH.
    3- In Define Payment Method for Company code, I hit a snag because Under Form Data, there is only the "Drawer on the Form" segment; the entire "Forms" segment where you'd select your script is missing.
    Bottom line is How do I set up payment advice for ACH for a EU company paying EU vendors? (am I even asking the right question here?)

    maybe OP want to extract all numbers from his inbox using regular expressions?

  • Automatic creation of remittance advice for employee expense reimbursements

    Hello experts
    Is there a way to have remittance advices for employee expense reimbursements created automatically at the time of payment media run? In case of suppliers, in the supplier base you can heck "Advice Required" and then at the time of media run the remittance advice can be generated alongwith the payment. Is there a similar setting that can be done for employees?
    Thanks
    Gopal

    Hi
    Just to follow on from Ravi's reply:  most sites that I work at have the report RPRAPA00 scheduled to run on a periodic basis (define the job via transaction code SM36) to automatically create employee's vendor accounts.   A screen variant is usually saved for the program, and then the batch session is monitored on a regular basis to ensure that it has run successfully.

    Found the problem.
    Paper size for those documents are actually A5 size.
    Solve it by adjusting the Scale to paper size in the printing option to the size that our printer is set to printout 
    which in my case is 'Letter'
    Hope this helps anyone who is encountering the same problem.

  • RAID block size for final cut pro x

    Just got one of the new late 2012 27" iMacs and a 6 TB LaCie Thunderbolt drive. Can finally edit the video I took last spring. I'll be using Final Cut Pro X, and doing a lot of multicam stuff with 4 or 5 views and a separate audio track. The LaCie came formatted as a mirrored RAID. I'm going to change that to 0 (Striped RAID set), but am wondering what block size to set. The default is 32k, but I have read that this ought to be increased to the max (256k) for video editing. I have also read it should NOT be increased. And the posts I have read have all been at least 3 years old. So let me ask you all--what block size would you recommend for my situation?
    Thanks in advance!

    Hi Eddie...
    This depends on what kind of source footage you are editing....
    For compressed Video, Audio and Uncompressed audio 128k
    I have only had BAD results with 256k. 64 is also weird. Whereas 32 is fine.
    All my RAIDs have 128k for audio/video editing
    you can go further if you editing Image Sequences.. but according to my own findings and I have been dealing with raid since years.... 128k does the job the best.
    Rule of thumb.... The smaller the file sizes you are putting the RAID the smaller the block size. And vice versa.
    I.e. You would cripple the raid performance if storing a database on it, having a block size of 256. In case of servers and OS 32k would be a good choice, perhaps even 16k if supported.
