SCSI Enclosure Services

Eric Schrock has done some really cool work with integrating disk (SMART) /platform monitoring (IPMI) information into Opensolaris.   Just recently, he has extended FMA with a new technology called SES (SCSI Enclosure Services) into build 93 of OpenSolaris.

This looks like some really cool stuff.  The following was taken directly from his blog on the examples of using the new fmtopo utility to map out an external storage array.
