i think the way the question was phrased about an HBA being a target threw people off.

SCST looks like a implementation of COMSTAR functionality. COMSTAR lets most block level  to be targets over iSCSI, FCoE, iSER (iSCSI over Infiniband), etc. 

iSCSI over ether pretty straight forward. There is plenty of Solaris-Solaris documentation available from Oracle. I wrote a blog about Solaris-Windows and Rockwood did one on Solaris-Mac. 

The Solaris derived implementation of iSER requires that the switch runs a subnet manager, which are commonly available in Infinniband switches. The Linux implementation allows for a back to back set up without a Infinniband switch.

does that help?
