ZFS Storage Layout Whitepaper v2.0

Thanks to @HoneyBadger iX Systems updated the old resource by fixing the errors and further improving it. I have thus removed the option to download the old PDF from this resource, and uploaded at this link for posterity.
While the resource is valid there are a few mistakes, namely:
  • page 4, Storage space efficiency formula
    • correct: 1/N​
  • page 5, 6x 2-way mirror
    • correct Read IOPS: 3000​
    • correct Write IOPS: 1500​
  • page 6, 4x 3-way mirror
    • correct Streaming read speed: 1200 MB/s​
  • page 11, Scenario 3​
    • a SLOG is not a write cache​
