As Jussi said, partitioning disks on a ZFS only system is uncommon.
Splitting an SSD between log and cache generally isn't a very performant
option. Devices that make good cache devices may not be good logs. With
SmartOS running KVM, there is a big gain from log devices, but not much from a
cache.
On this subject:
What is the current thinking on the need to mirror slog and/or L2ARC devices?
There never has been any need to mirror L2ARC device, you might get a
small performance gain reading from a mirror. Now logs are recoverable,
there is little benefit from mirroring log devices.
Cheers,
