LSI Corporation today announced it is sampling the
LSISAS2208 dual-core 6Gb/s SAS RAID-on-Chip (ROC) IC to OEM customers.
The high-performance LSITM SAS ROC is intended to support the
forthcoming PCI Express 3.0 specification, currently under development
within the PCI-SIG, and provide I/O performance levels that meet the
needs of next-generation server platforms based on PCI Express 3.0 and
flash-based solid-state drive (SSD) storage.
The draft PCI Express 3.0 specification will extend PCI Express
data rates up to 8.0 GigaTransfers per second per lane, doubling the
host bandwidth that was achievable with previous generations.
Integrating the latest enhancements in PCI Express and SAS technology,
the third-generation LSI SAS ROC will deliver performance levels of up
to 600,000 input-output operations per second (IOPS), allowing server
platforms to take full advantage of the performance benefit of SSDs for
applications such as Microsoft Exchange Server, databases, Web serving
and business intelligence.
"Performance is becoming more critical in today’s enterprise
environments, especially as more enterprise-class solid-state drives
are deployed," said Jeff Janukowicz, Research Manager,
such as the next-generation LSI ROC, coupled with PCI Express 3.0-based
server platforms, are designed to maximize the performance benefits of
The LSISAS2208 ROC integrates a 72-bit DDR3-1333 SDRAM interface, specialized
acceleration engines and a high-performance dual-core 800 MHz PowerPC
processor for optimized RAID performance. In addition, the LSISAS2208
ROC incorporates enhancements such as single root I/O virtualization
(SR-IOV) for greater performance in virtualized environments, improved
system performance and data security, and more finely-tuned quality of
"From server generation to server generation, leading OEMs have
relied on the LSI SAS portfolio to meet their storage demands," said
Bill Wuertz, senior vice president and general manager, Storage
Components Division, LSI. "As the industry now begins to look towards
the PCI Express 3.0 wave of server platforms, the new LSISAS2208 ROC
will enable OEMs to take advantage of the performance capabilities
offered by the new specification, once again demonstrating LSI’s
ability to help keep our customers at the forefront of industry
"We are excited to see LSI implementing the latest PCI Express
specifications in their next-generation products," said Al Yanes,
PCI-SIG Chairman and President, commenting on the early adoption of the
upcoming PCIe 3.0 technology. "LSI has been an active member of the
PCI-SIG since its inception participating in numerous technical working
groups and developing products which include PCI Express technology."
Since the inception of SAS, LSI has delivered an
industry-leading portfolio of products including controller ICs,
expanders, host bus and MegaRAID adapters, RAID-on-Motherboard (ROMB)
solutions and storage systems. Based on a 25-year track record of
hardware and firmware expertise and extensive validation processes, LSI
is the silicon-to-systems supplier of choice for OEMs that want to
deliver a broad set of storage solutions.
