SES can be presented in a number of ways, but basically it is there.
It is normally presented to an OS by the Controller connected to the 
backplane.

For SAS, via the sas bus and controller.
For Sata, via i2C or GPIO usually to the controller or motherboard.

Yes.

Yes, via the sas (or scsi) commands understood by the ses device.

For OpenSolaris/OI, it doesn't currently have the appropriate software 
for non-Sun hardware.

With the right hardware, and some work, there are some ways to do it.
If you have an LSI 2008 SAS2 controller with IR firmware, this method 
will work.

I plan to write something to make this easier (but only only with this 
hardware).
