  • ZIL - ZFS Intent Log (SLOG)
  • One or more SSD
    • Not Mirrored
    • RAID0 for more performance
  • Need SSD tuned for writes and long life
    • SLC may be best, but more expensive
  • With supercapacitor to guaranty writes are completed
  • 3rd-gen Intel SLC SSDs should meet this requirement
    • X25-E (eMLC, supercap)
    • Vertex 3 Pro
    • C400?
