zfs - smartOS HPC config suggestion

I'm configuring a brand new HPC server and am interested in using SmartOS because of it's virtualization control and zfs features. Does this configuration make sense for a SmartOS HPC, or would you recommend an alternative?



System Specs:
2x 8-core xeon

384 GB RAM
30 TB HDs with 2x512GB SSDs



Uses:
- zfs for serving data to different vms, and over the network; 1 SSD for L2ARC and 1 for ZIL
- typically 1-2 ubuntu instances running R and custom C/C++ code



My biggest concerns as a newbie to SmartOS and ZFS are:



(1) will I get near-metal performance from ubuntu running on SmartOS if it is the only active vm?

(2) how do I serve data from the global zfs pool to the containers and other network devices?
