Expand Your Horizon
LSI 3ware SATA+SAS RAID controllers provide a new level of reliability, availability, and
performance to businesses that are facing storage challenges, particularly in sequential I/O
intensive and multi-stream environments. This 3ware controller, great for inside-the-box
connectivity, employs the latest in LSI RAID-on-Chip (ROC) technology and provides a higher
standard of data protection and performance.
Offering data transfer rates of up to 6Gb/s per port, the latest generation of 3ware SATA+SAS
controllers provide many new features while also ensuring investment protection for existing
SATA and SAS implementations. LSI delivers unprecedented power in multi-stream RAID
environments where performance, redundancy, and data protection are most important.
6Gb/s SAS Advantage
6Gb/s SAS is designed for backward compatibility with 3Gb/s SAS as well as with 3Gb/s SATA
drives. In addition, 6Gb/s 3ware controllers deliver significant performance improvements
in both read and write applications regardless of drive speed. StorSave™ strengthens array
performance during peak usage by allowing the controller to use both controller cache and
disk cache for RAID operations. Other new features of the 6Gb/s 3ware SATA+SAS controller
cards include greater signal integrity using Decision Feedback Equalization, support for more
sophisticated SAS topologies using Expander Self-discovery/Self-configuration, and additional
safeguards to enhance data protection.
StreamFusion™+ Performance
3ware’s advanced algorithms allow for optimized reads and writes in multi-stream
environments. StreamFusion+ enables higher throughput even in degraded modes to
deliver a superior standard of data protection and to boost performance. It is the result of
countless hours of engineering aimed at delivering breakthroughs in high-load applications
and providing enhanced features and functionality in all environments. Focusing on the
latest technology trends and customer requirements, StreamFusion+ firmware reaffirms our
commitment to customer success and industry leadership.
