Device Overview

Summary

The Tachyon® 12G SAS 8-port controller enables software leverage between controllers and protocols, providing system designers with end-to-end diagnostics and error handling mechanisms to increase system performance, availability, and most importantly, manageability. Unique end-to-end features and algorithms can be achieved from host to hard disk drive by using these controllers in combination with Microchip’s market-leading maxSAS family of SAS/SATA expanders, multiplexers, and enclosure management solutions.
