At long last, the COMSTAR SAS port provider is available.
Unfortunately, it is not an officially released product. Binaries are available, however. You can read all the details and get the binaries from the COMSTAR project page.
You can click on the Using the mptt SAS target-mode driver in COMSTAR link to go directly to the information about the SAS port provider. The tarball of binaries is available from the "Files" link on the COMSTAR page.
Feel free to bring up questions about this on the storage discuss alias.
Enjoy!
