An SCST design overview diagram together with SCST API documentation can be found here: http://scst.sourceforge.net/scst_pg.html (sorry for the language imperfections on this page, which should not affect readability though). Some distinctive features of SCST that give it its high bandwidth and low latency but that are not mentioned on that page are: * Multithreaded command processing, even for a single LUN. * Much care has been taken to minimize command processing latency. This is why a dedicated SGV cache has been implemented in SCST, which is, as far as I know, a unique feature. It is also important to know that the SCST project has a large user base, and that the SCST users appreciate the proven stability and reliability of the SCST software and also its excellent SCSI conformance.
