The first article in this series of three articles discusses SAS connectivity and introduced the basic concepts of how SAS devices connect together as well as how SATA devices connect into a SAS infrastructure. The second article discussed how SAS connectivity has evolved over time. This third and final article in the series provides a review of the connectors and cable assemblies released for each revision level of the SAS standard.
SAS has experienced very fast growth based on the enhancements described in the previous articles. These expanded opportunities have created a need for the standardization of new connectors on several occasions. This article will show the chronology of these changes, by the SAS standard revision level, to provide an understanding of why convergence is important for revision SAS 3.0. Graphics are included for each of the revision levels to provide a visual connection to the product requirements as defined on the Advanced Connectivity Roadmap. The need for connector convergence in revision 3.0 becomes apparent and appropriate as the article unfolds.
Please read all three articles to understand the complete SAS connectivity story.
