Here’s Apple’s doc on the subject. It appears that your fully populated RAID comes from the factory with upper and lower preset to their own RAID so that all you need to do is combine upper and lower into an appropriate RAID config for your needs. I am not the world’s expert on this subject, thought my present Xserve setup has been working without a hitch for about 2 years now. So I guess that counts for something…

Do this in two steps: First, starting from scratch, create a RAID 5 with one side — “upper” 7 drive units. Then so the same with the “lower” units. Then combine the upper and lower RAID 5’s into a RAID 0. This is RAID 50. It combines the redundnacy protection of RAID 5 on each level, plus the efficiency of RAID 0. Be sure that Journaling is OFF.

I had the same problem (double frame, output offset) insert editing a single clip in the middle of a program with the Kona HD working in 23.98 1080p mode back in 2003. At the time, I found the following advice:
>>>The only way to make frame accurate insert edits on Kona HD is to go back to the 2.3b7 BM drivers from over a year ago.
If you have to make inserts with your current setup, try resetting the Device Control and you will be able to make 1 edit that doesn’t repeat the first frame. (lousy work around)
Ever since the 4 series of drivers came out I’ve lost the ability to do frame accurate inserts or assembles in 1080P 23.976 to D5 or HDCam. I have told both BM and AJA about this problem, the exact same problem exsists on the Decklink HD.
Maybe when AJA comes out with thier own drivers this will be fixed.<<< I have found that Panther Cache Cleaner has cleared up a few output problems (incorrect channel patching on Kona2), though it seems recent drivers have permanently fixed this problem. Also, do you edit to tape from the Canvas or Viewer? i always output from the Viewer and never get that "incompatible compression" error, and who knows what else I am avoiding. I also seem to recall back in 2003 that if I tried to output consecutive masters with IO with the same Edit to Tape window (without closing the window then re-opening it to do the second tape), I would get a terribly inaccurate output on the second tape -- unlike my old Avid where you could output a million masters with the same Outut setup. This problem seems to be solved on K2, but I haven't checked on my IO for same problem. I have done several tests similar to yours and only have issues in HD. IO and Kona2 in SD all seem to be right on when outputting an entire program. I will test out an insert edit and report back. Steve Covello double wide post -
If the issue is simply that, while outputting, you see a horizontal sync bar on screen, don’t sweat it. Check your recording after it is done. I’ll bet you a donut that the recording is perfectly fine.
For some friggin reason the Fisher Price UVW-1800 never displays a properly synced signal while recording, even from a house referenced source. I don’t know why this is, and I, in my hubris, honestly believe I have it configured correctly — with black burst reference input, and the proper termination and everything. It’s just the nature of that machine since day one. this has happened while outputting from Avid and hard recording from D-Beta in component and from composite sources as well, so I don’t think it has anything to do with Kona or FCP.
Just go with it…

We use a converter box in the K2’s secondary SDI pathway to get CV out:
This is the Marshall Electronics website. Goto the Video Converters menu and select BC-0301-10. There is a 10-bit model, and 8-bit model. Right now, sans K-box, the pathways are as follows:

I believe the capture sans pulldown function will only work under the following conditions: 1) you are capturing via firewire DV, not IO; 2) you are playing back a DVCPro acquired taped on a Panasonic playback product (camera, deck, etc.), not a Sony product; 3) you have the correct Easy Setup which corresponds to the kind of pulldown cadence (conventional, advance) that the footage was acquired.
The reason for this is that the DVCPro cameras record a flag data stream on tape along with the picture/sound. It is carried via firewire connection only, so SDI data doesn’t “see” the flags on tape. FCP cannot “see” the flags otherwise and can’t distinguish between pd and regular frames.
After you have captured, perhaps you could use the IO as a playback throughput device, but as far as I know, it cannot remove pulldown frames on capture via analog or SDI (I just checked the preset for IO and the Capture Settings allow for removal only from FW sources). Maybe there;s a hack for this but not that I’m aware of.

I would have a really bad feeling about trying to capture live material to a drive of ANY format without having simo tape backup. Even in today’s tapeless audio recording/mix studios, they still record AVO to DAT as a backup. Otherwise, one hiccup and you’re completely screwed.
Seems to me like you should tap out all of your cameras to a stack of DVCProHD decks that are slaved to a jam sync TC setup (as previous poster suggested) which will save you an immense amount of headaches now and in the future. And surely there will be someone who will want to have a vhs screener of the meterial. Are you going to take down your editing systems just to make dubs? What if your RAID goes down? Flood? Tornado? Just kidding, but still. It doesn’t take much for the whole thing to come crashing down, IMHO.

I believe Capture mode defeats the normal output pathway temporarily until you close it out. Something in there seems to “forget” to switch back playback frames when returning to editing mode. Strangely, some rookie editors (no offense implied) seem to like to keep editing systems in capture mode all the time even when not capturing (I’ve seen this in training people on Avid and FCP — why is this???). Though this doesn’t do any damage, it must seem perplexing to them why the system can’t seem to figure out what to do…

I reported a problem a while back similar to yours, but on HD outputs. Even with the new driver today, I still seem to have sync issues with HD outputs. Here is the response from the query I placed originally:

Maybe when AJA comes out with thier own drivers this will be fixed.<<< Although the BM driver is gone, try the reset. Also, try Panther Cache Cleaner, medium cleaning on all selections - User, System, etc. this solved a couple output problems for me. try also outputting from the Viewer panel instead of the Canvas, and have the deck in Input Video rather than Ref. Try striping by inputting blk into the DB's composite input, set the deck to Internal TC generation with LTC/VITC on Auto, and set the TC start preset in the menu/jog dial. I trust the DB's internal TC generator more than anyone else's. MAke sure you also set NDF or DF as appropriate. Let us know what happens. I will be doing a frame accracy test with the latest K2 driver soon and will report. steve covello double wide post
