Will it work?
I am putting together a new editing system for a small production company butam not sure if it is going to give as much power as it is needed for HD editing. It is going to be based on Aja Kona2 so (IMHO) this is the best place to ask for professional opinion.
At this moment I already have a base station (2×2.5GHz G5, 2.5GB RAM, FCP 5.x) and Kona2 is a must, but I need to find out how much and which disk to put in.
My first idea was to put in an Atto UL4D and to connect to it Huge MediaVault U320-RX (dual channel). It should give some 300MB/s and (again, IMHO) this should allow my customer to see at least 2 streams of uncompressed HD. Am I right here?
But then I came accross another idea. Why shouldn’t I put in and Atto FC42 and connect MediaVault 4210 to it. If bechmarks are true, I should get a bit more then 500MB/s (almost 4 uncompressed HD streams)!!!
Problem is that I am not familliar with FC as I am with SCSI and that I never saw any FC based system working.
Does anyone here has any idea how that works with Kona2? Maybe someone has an access to such a system or
even has been working on it? Is it stable? Is it safe?Thank you in advance,

Jadranko,
I have the Fiber and HUGE FC4210 Combo. It is great. It is reliable and I have had no problems. With the disk 85% full in raid three mode I still was getting about 380 MB/sec read and write times. 4 Gigabit fiber is a viable solution.
It is great in both HD and SD and 7streams of DV, 8 of Uncompressed 10 bit, but here is the down side.
NO STREAMS OF RT IN HD uncompressed. This is doe sto a limitation inthe KONA 2 Driver not drive speed or FCP. The moment you use a 3 way CC or and effect in 10 bit uncompressed there is no real time.
This is why it is good to have as large a drive as possible, because you are going to always double your footage with the rendering you have to do. So if you plan on HD onlining 90 miute films you will need more than 180minutes of free space to make room for the render files.

David.
I do not know where you got this info but it is totally incorrect. The K2 Driver has NO control for RT effects in FCP, RT effects in FCP are the result of a combination of RAM, Read /Write Drive speed, GPU performance and CPU speed.gary adcock

Working with Fibre in FCP is a dream!, long cable runs and no worries. you will love everything but the cost, but in a multiuser environment it cannot be beat. A single user has SATA and SCSI options ( SATA being the brightest star right now)
As for the Sync – if you are not in a facility with house sync you can force the sync on the Kona 2 to be the video in signal if needed (or you can turn it off) However some decks really don’t function properly without a sync signal (D5 for one) so the AJA answer is correct – sometimes you can live without it -especially in a smaller suite– but depending on your workflow it may be required.

Gary,
In 10-bit uncompressed HD I have yet to see an RT filter not need to be rendered. 3-waycc, titles, everything needs to be rendered.

Sorry, but I do not understand this!
Did you write that there is no way that I will see at least one stream of HD comming from FC connected FC4210 in real time?
All I want to see is a stream of video with no effects, no transitions or anything, just a simple stream. Will I be able to see it?Regards,

Yes, It will work fine.
I use my Huge array for this type of work daily. (I have a 4110).
the other comments were about FCP’s Realtime effects (RT extreme) which are very limited when working with Uncompressed HD content. IT had nothing to do with what the drive was capable of.
