Here is my hardware.
My main concerns is performance, capacity would be nice, but not a priority. I want to have a pleasant snappy experience viewing old footage. I have another (slower) system where I will be storing files long term with better redundancy.
I've come up with 3 possible layouts, and was hoping to get some feedback.
Layout 1 - 2 pools
Pool 1 (VMs only) - 4x4TB drives in RAID10. 1TB L2ARC, DC P3700 ZIL/SLOG - data quota of 80%
Pool 2 (surveillance) - undecided. Either all mirrors, or maybe buy another drive for 5x 3drive raidz1
The primary benefit of this layout, is that with a large ARC and a 1TB L2ARC, plus an 80% data quota, I can effectively cache ~18% of the entire pool. This should give me great performance for the VM's. Would this outweight the benefit of the additional mirrors?
Layout 2 - 1 pool
use all 18 drives, 9 mirrors, 1TB L2ARC, P3700 ZIL/SLOG
I'm just not sure if the additional vdev mirrors for this setup, will outweigh the benefits of the increased caching ability on layout1.
Layout 3 - 1 pool
use all 18 drives, 6xraidz1, 1TB L2ARC, P3700 ZIL/SLOG
this has the highest capacity, I was wondering if this would be a nice in between for great performance, and capacity.
