3P-2 Best Practices for 8 Chnls?

What are folks doing as far as external drives and workflow when using all eight channels on the 3P-2?

Do you mean for backup of data or exporting clip information?

Hello Kane - always good to chat with you, hope all is well after NAB!
Work Flow: Live pilot for a network show this weekend. Bringing in eight NDI feeds from independent stream via PC, into the 3P-2. Record all eight feeds, clip big chucks and play them out over NDI (or export playlists) to the TC2 Elite.
The installed single drive in the 3P-2 doesn't keep up with a ten-channel production (didn't expect it to). I'm plugging in four 2-TB SSD's rated at 1000MBS each via USB to see if that supports the flow.
Wondering if anyone else has experience pushing the 3P-2 this far and what worked for them.
Thanks!
 
The internal storage on 3P2 is RAID (five SSD's striped) and will keep up with all 8 channels of recording (there aren't 10 channels of recording, but 8 recording inputs and 2 playback output for the 10 channels).

I'm personally not a fan of USB storage for long format recording. Despite the specs, USB storage never seem to keep up.

I've tried using 3PLAY with network storage (and NRS system). It worked, but there was a delay when you would start playback.

Still checking in on this thread for any other "best practices" on the 3Play and Play2. I was in the engineering support chair for two college baseball tournaments this past week - one using 3Play and one using 3Play2 - a total of 21 games over five days between two facilities. We experienced constat replay issues in both rooms. Mostly stuttering and lag on playback, an occasional crash, and decisions to reboot as early as the top of the first inning after scene-sets were recorded. Internal drives, external drives, drives defragged, tried turning audio off, local inputs, NDI inputs, still a frustrating week. I'm in need of some adult supervision!

Wondering on my end if you had some chance after (during) these 2 productions to take a closer look onto the production network performance between these two facilities.
As you mentioned use of NDI Inputs too, I´m thinking if the problems (stuttering and lag on playback) may be because of some (NDI) network issue / trouble.
Or are you sure this is more related because of performance(s) issues of connected physical drive(s)?

Now that the college baseball season is over, I have time to do a deep dive into at least one of these systems. I installed the 3Play2 system in a small D1 university two seasons ago and it's never been as solid as I expected. It's currently running with four local SDI inputs; audio is all set to nats from input 4 (embedded). Setting everything to interna drives today, cleaning them out, defragging and checking software. They have a small wheelchair basketball tournament coming up, we'll see how it performs.
 
Just got our 3Play2 with 8 inputs. Right now we're working off 1 hard drive directly on the machine. (The D drive). We've done 2 events.

So far, we've had 2 issues:
1) we've noticed is while recording, the time left on disk fluctuates. Not a big deal but certainly something I hope doesn't continue
2) The 4th input can be seen while recording, but not outputted for playback. A restart fixed that for the time being.

Then we export the playlists to an external drive to bring onto our CMS server. Then delete the session and create a new one from an empty template session that only has a few videos and graphics.
 
On our 3rd event last night, we had some major playback issues. Whether T-Bar or play button, we kept seeing a stuttering upon clip playback of recorded clips within the session. Could this be because we're only working on the D Drive for all 8 inputs plus 2 outputs? Or could it have been an NDI issue?

Our setup is cams via SDI/Copper>NCIO. From there the TC1 and 3P2 picks it up. We never had an issue on the tricaster or NCIO nor inputs on the 3P. Just playout. We ended up restarting the machine and starting a new session with 4 inputs and not record 5-8. Then were fine the rest of the show.

Any thoughts?
 
Hi Tjdivito PSU,
Vizrt recommends, not to record more than 2 Inputs on the same drive (okay - that's meant for externals...). But...

When the RAID (D drive) is empty, it can handle somewhat around 40 sources in HD - but it looses easily up to 80% of speed (and above) when filled up above 50%.
