描述 Description

The Tachyon® highly-integrated 12G SAS and 3G/6G/12G SATA protocol controller family is optimized for fabric-attached RAID storage system applications and SAS/SATA HBA applications, significantly increasing total system performance, diagnostics, scalability and manageability.Tachyon controllers provide an efficient and scalable architecture that enables industry-leading system performance. They provide application-programming environments that are compatible with other members of the Tachyon SAS/SATA controllers and Fibre Channel controllers, enabling software leverage between controllers and protocols.The controllers provide 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 (HDD) or Solid‑State Drive (SSD) by using these controllers in combination with market-leading SAS/SATA expanders, multiplexers and enclosure management solutions.
