MILPITAS, Calif., Nov. 15, 2011 /PRNewswire-FirstCall/ --
ACCELERATING INNOVATION SUMMIT -- LSI Corporation (NYSE:
LSI) today announced it is demonstrating the industry's first
12Gb/s SAS expander IC this week at the LSI Accelerating Innovation
Summit and Technology Showcase in Milpitas, Calif.
The technology demonstration highlights the performance benefits
of a 12Gb/s SAS solution with existing 6Gb/s drives compared to an
end-to-end 6Gb/s SAS solution. The demo utilizes the
next-generation LSI® 12Gb/s SAS expander and 12Gb/s SAS I/O
controller connected to sixteen 6Gb/s SAS hard disk drives (HDDs).
The 12Gb/s SAS solution with 6Gb/s SAS drives in a PCI Express® 2.0
system achieved a 65 percent increase in throughput and a 58
percent increase in IOPS (I/O operations per second) performance
compared to the end-to-end 6Gb/s SAS storage solution.
"12Gb/s SAS components provide the opportunity to extend
existing investments in 6Gb/s drive infrastructure while maximizing
storage performance for I/O-intensive applications, cloud
datacenters and virtualized server environments," said Bill Wuertz, senior vice president and general
manager, RAID Storage Division, LSI. "With PCI Express 3.0
platforms on the horizon and enterprise adoption of solid state
drives on the rise, 12Gb/s SAS will be essential to unleashing the
full performance potential of next-generation server
platforms."
The 48-port 12Gb/s SAS expander supports SAS data transfer rates
of 12, 6 and 3Gb/s and SATA data transfer rates of 6 and 3Gb/s. The
expander can connect directly to up to 44 SAS or SATA devices,
including HDDs and solid state drives, and provides table routing
to support connections of up to 2,048 SAS addresses.
The expander incorporates the latest enhancements in SAS
technology as well as innovative LSI IP, including End Device Frame
Buffering (EDFB) technology. This unique LSI feature is designed to
help facilitate the industry transition to 12Gb/s SAS-enabled
systems by allowing users to take advantage of 12Gb/s speeds while
utilizing existing 6Gb/s drive and backplane infrastructure.
Intelligence in the expander buffers data and then transfers it out
to the drives at 6Gb/s speeds in order to match the bandwidth
between faster hosts and slower SAS or SATA devices.
According to industry estimates, 12Gb/s SAS market adoption will
begin with the release of individual SAS components and devices,
and gain momentum as tier-one OEMs begin production-volume
shipments of 12Gb/s SAS-enabled servers and external storage
systems. Production-volume shipments of 12Gb/s SAS-enabled servers
are estimated to occur by early 2013, followed by the availability
of external storage systems by mid-to-late 2013.
Since the inception of SAS, LSI has delivered an
industry-leading portfolio of products including SAS ROC,
controller and expander ICs, host bus adapters, MegaRAID® and
3ware® RAID controllers, 6Gb/s SAS switches, advanced software
