4k Video Editing DIRECTLY on NAS over 10gbe - Any real world use case/case study?

[xeronine]

Been reading up on the various forum posts. Seems most of the posts are for BOM specs for editing directly on the NAS over 10gbe with multiple editors with footage and rushes fully online. Our use case is very similar:

Edit Bay 1 - iMac Pro running FCPX with DAS (Thunderbolt3) @ 32 tb
Edit Bay 2 - PC AE Box with DAS @ 24tb
Edit Bay 3 - PC running Davicini Resolve with DAS @12tb
Edit Bay 4 - Hackintosh running FCPX with DAS @16tb

Mostly deal with ProRes 422 HQ at 4k (occasional Red Raw) and transferring over 1gbe is tedious. Faster to dump rushes to a USB 3 drive and then copy to the other bays. Obviously, this creates an asset management issue, wastes quite a bit of drive space, and significantly bottlenecks the workflow. We do not have a dedicated data wrangler to collect project files, so the footage tends to stay on the DAS attached to each edit bay workstation.

QUESTION: is anybody up and running over 10gbe and editing/motion graphics/grading, etc ... directly off a FeeNAS box in a collaborative workgroup/workflow?

Not looking for build specs but your experience if you've deployed a FreeNas box. Pitfalls? Issues? How many 4k streams? Performance? What's your baseline bandwidth throughput? What speeds were you attaining over your 10gbe LAN?

Looking for real world use case experience/insight please, and not synthetic benchmarks!

TIA!

Cant say that I do any video editing. The latency would be the first thing you notice. The second is that your sharing that 10gbe (1.25 GB/s) across your editing stations. You can help by using a managed switch with LACP load balancing and trunking multiple links on the NAS. That's assuming the bottleneck is the network and not the storage. You will likely want an all flash pool for live projects and a rust pool for archival needs. Oh and a boat load of RAM.

Linus Tech Tips has an episode talking about their setup. That may be helpful.

Assuming you plan on using SMB then you will need to disable SMB3 signing on your Mac clients or you will not even get above 1Gb let alone anywhere near 10Gb.

In my experience 10Gb out of the box via a single SMB connection to FreeNAS will get you about 6Gb/s Read/Write. No doubt if you play and tweak you will get better. If your FreeNAS is fast enough (CPU, RAM, Pool Speed) and has enough networking bandwidth then it should be able to sustain multiples of these.

Talking about SMB it important to mention that its single threaded. This means clock speed will be a major factor. Faster clocks over core count!
