LSI Ships 12Gb SAS RAID-on-Chip and I/O Controller

Doubles data transfer of enterprise systems deploying SSDs.

LSI Corporation ships production-level 12Gb SAS RAID-on-Chip (ROC) and I/O controller solutions to OEM customers.

12Gb SAS technology is designed to deliver double the data transfer rate of prior SAS solutions and unleashes the performance potential of next-generation enterprise systems deploying high-performance solid-state storage.
 
The new products include:

At CeBIT, LSI demonstrated the LSISAS3108 ROC plus MegaRAID 6 technology along with the LSISAS3x48 SAS expander. For those looking to take advantage of 12Gb/s speeds with existing 6Gb/s drive infrastructure, LSI showcased DataBolt technology, a bandwidth optimizer performance acceleration feature.

DataBolt technology, combined with the extended bandwidth of PCIe 3.0, is designed to deliver double the throughput performance while using today’s 6Gb SAS or SATA drive solutions. With this feature, DataBolt technology offers product enhancements and future proofing that helps protect customers’ HDD and SSD investments.
 
"The explosive growth of data in cloud and enterprise datacenters drives the need for a higher-performance storage interface that enables more rapid access to data," said Jeff Janukowicz, research director for solid state storage and enabling technologies at IDC. "12Gb SAS addresses this requirement by doubling the performance of current 6Gb SAS-based systems, and helps to unlock the potential of PCIe 3.0-based systems and the most recent solid-state storage solutions."
 
By doubling the data transfer rate of 6Gb SAS solutions, 12Gb SAS allows the SAS infrastructure to deliver bandwidth that exceeds that of PCIe 3.0 with a single HBA. The improved bandwidth, backed by I/O processing capabilities to maximize link utilization, supports increased scaling of traditional HDDs as well as improved SSD performance. 12Gb SAS also provides customers with investment protection with backward compatibility with 3Gb and 6Gb SAS.
 
"Today’s announcement underscores LSI’s 12Gb SAS leadership as we continue to drive first-to-market solutions for data protection and acceleration," said Kelly Bryant, VP marketing, RAID storage division, LSI. "With leading designs and unique capabilities like DataBolt technology, LSI 12Gb SAS solutions are designed to deliver the performance required for the most demanding next-generation server and storage platforms."
 
Production-volume shipments of the 12Gb SAS ROC and 12Gb SAS I/O controller are occurring this month, followed by the availability of 12Gb SAS expanders, MegaRAID controllers and HBAs in Q2.
