PM8071B1-F3EI

The Tachyon® PM8071B1-F3EI is a versatile and highly-integrated 12G SAS and 3G/6G/12G SATA protocol controller family, specifically designed to meet the demanding requirements of fabric-attached RAID storage system applications. With a focus on optimizing total system performance, diagnostics, scalability, and manageability, this controller family offers a superior solution for SAS/SATA HBA applications. Its efficient and scalable architecture allows for industry-leading system performance and provides compatibility with other members of the Tachyon SAS/SATA controllers and Fibre Channel controllers, enabling seamless software leverage between controllers and protocols. Furthermore, the controllers provide end-to-end diagnostics and error handling mechanisms, ultimately increasing system performance, availability, and manageability. By combining these controllers with market-leading SAS/SATA expanders, multiplexers, and enclosure management solutions, unique end-to-end features and algorithms can be achieved from the host to the Hard Disk Drive (HDD) or Solid‑State Drive (SSD). In summary, the PM8071B1-F3EI sets a new standard for performance and reliability in fabric-attached RAID storage systems and SAS/SATA HBA applications
