I've been evaluating repository options for a size up to around 300TB, and am fairly convinced by ReFS at this point. I am looking at big Supermicro box, had considered storage spaces (not S2D), but expect I will get better performance from a hardware RAID setup.
Rather than just sticking a load of 10TB drives in a RAID60, I was considering a tiered approach with say ~60TB of RAID10 for ingestion, then moving data from the ingestion area into the RAID60 for long(er) term retention. I am concerned how this would play with ReFS block clone, I expect if I used a scheduled task to move these files I wouldn't get any benefit from ReFS. I understand clone wouldn't work between the two areas anyway, but I would like to use block clone as I copy additional jobs into this area. What's the best plan of attack - Backup job to RAID10 followed by BCJ to RAID60?
Any ideas or experience welcomed.
