Anybody have experience with Media Grid especially with live ingest and growing files?
The pluses are it does scale well and is purpose built for video workflows. It does use a custom filesystem driver but there is no cost per client.
Minuses are there is no chassis redundancy and each chassis is 5 RAID4 2+1 sets, so 16 1TB drives would only yield 10TB. Without chassis redundancy I'd expect replacing old chassises would be difficult.
