Function coverage ================= The following table lists SAS Serial Management Protocol (SMP) functions in alphabetical order in the left column. The second column is the standard or draft that the function first appeared in or was extended. The final column is the utility in the smp_utils package that invokes that function on a given SMP target. Notice that many of the newly introduced functions have no corresponding utility.

In SAS-2.1 (spl-r07) and SAS-3 (spl2r03) these 4 functions are not defined (the ENHANCED function codes are "restricted for SFF"). The sas-r05.pdf draft is taken to represent the original SAS standard (ANSI INCITS 376-2003). The sas1r10.pdf draft is taken to represent the SAS-1.1 standard (ANSI INCITS 417-2006). The sas2r16.pdf draft is taken to represent the SAS-2 standard (ANSI INCITS 457-2010). Now there is a SAS-2.1 standard at the draft stage and it has been split into 2 documents. The document containing the SMP functions is called the SAS Protocol Layer (SPL). So far only a small number of changes have been made to the SMP functions in the SPL draft. Work is ongoing on a SAS-3 standard in which a phy can run up to 12 Gbps. The document containing the SMP functions corresponding to SAS-3 is called SPL-2 and the first draft was recently placed on the t10 ftp site. Doug Gilbert 23rd September 2011
