Hello, so, I am trying to figure out if I understand ZFS and how I should go about setting up TrueNAS. My current hardware is A dell poweredge R720XD, that has 2 SATA boot SSDs on the rear backplane in one mirror and then 24 drive bays in the front I intend to populate with 1TB SAS drives. I was going to start with 16 drives and add in groups of 8 as needed using first the remaining 8 bays and then MD1220s on an H810 flashed to IT mode. because of this I was planning to set up RAIDz2 vdevs with 8 drives each, starting with 2 vdevs and just adding 8 drives at a time to add another vdev to the pool. My understanding there is that I would have a fault tolerance of 2 drives per pool, and I would only lose 2 drives of space to parity per pool. so my initial 16TB of raw storage would have a fault tolerance of 4 drives (assuming failures across different pools) and a total space of 12TB (minus overhead) and that each subsequent addition would extend my fault tolerance by 2 drives and increase the total size by 6TB. I'm given to understand making the Vdevs 8 wide will give me reduced IOPS performance over say 4x4 drive Raidz1 vdevs, but since this will be used mostly for Storage and occasional video editing which I normally do off a single hard drive anyway, it didn't seem like it was worth the hit to fault tolerance since I would lose the same amount of data to parity but I could only lose 1 drive per vdev. do i understand this okay? is this a good way to set it up? should I go with 4x4 RAIDz1 instead? is the increased IOPS performance even worth considering on a Gigabit connection anyway? The server itself will be connected at 10Gig so my wife and I can both hit it at the same time, but both our computers are on 1gig links anyway, so max we can hit it with is 2gig. and even that is rare. to be honest the only reason it's going on a 10 gig link is because both the R720 and my switch have an SFP+ port.... so basically "because it's cool". we have absolutely no need for it, and I do not think it will be physically possible for us to try to saturate that link, let alone for ANY form of raid to be able to read or write fast enough to saturate it without me shelling out for SSDs and that would definitely defeat the purpose of buying second hand server hardware
