I currently have a bunch of cameras recording to SSD drives due to higher iops. The software we use kept complaining the drives were to slow. I record about a day worth and have the software transfer the recordings to spinning disk. I have about 6 vdevs of spinning disk. It seems the way the softwar…

2 x Intel Xeon Scalable Gold 6346, 3.1GHz (16-Core, HT, 3200 MT/s) It’s about 20-40% RaidZ 2 Would adding a fusion pool help? 300 cameras it records 1 min files so lots of files.

I would try to record directly to pairs of mirrors. Then move that data for archival purposes to a raidz2 storage. Mirrors are alot better for that kind of operation. Are there any threads at 100% on the cpu ?

Nothing at 100% right now I am writing a day worth to Nvme drives and it sends it to spinning disk every 8 hours but it’s really slow maybe 400mbps

How wide are your z2 vdevs ? How full is the pool ? How many drives ? Are they in a jbod enclosure or how are they connected ? Is that recording software running directly on Truenas ? If its doing sync writes you might benefit from a SLOG. But as i said. For high IOPS you need lots of pairs of mi…

[image] 07stuntar1_1: Would adding a fusion pool help? No. The special vdev takes up metadata and small files, it will not help with large video files and is absolutely NOT a cache where incoming files would be taken up before being moved to slower storage during a less active period (the way…

[image] etorix: For your big video files There are 1 minute with 6mbit/s so 45 MB per file. Is this already considered large ? I have no clue…honest question.

[image] Farout: Is this already considered large Yes. Usually the threshold is 1MB, but it depends on the performance and use case… and as such on the choosen block size.

Yes an Apple Fusion Drive would be nice

Please elaborate about your drives (both solid state and spinning rust) layouts.
