LSI Corporation today announced the sampling of the
industry’s first series of 6Gb/s SAS switches to OEM customers. The new
LSI model SAS6160 and SAS6161 switches
significantly extend the capabilities of SAS in direct-attached storage
(DAS) environments by allowing multiple servers to connect to one or
more independent external storage systems. SAS616x series switches are
designed to provide a low-cost and easy-to-use shared storage option for
rack-mounted server and storage installations in cloud computing, mega
data center and small- to medium-sized business environments.
Both SAS switches feature zoning, which enables storage resources to
be safely shared across multiple hosts, helping to maximize storage
resource utilization, eliminate islands of storage and simplify storage
management, backup and upgrades.
"The SAS interface is widely used inside servers and storage arrays,"
said Bob Laliberte, senior analyst at Enterprise Strategy Group.
"However, with the introduction of 6Gb/s SAS and now 6Gb/s SAS switches,
organizations of all sizes will have the ability to extend SAS beyond
today’s DAS environments to create simple, low-cost and high-performance
networked storage environments. Given the need for storage to support
virtualized server environments and the advanced features and benefits
offered by shared storage, these solutions are well-timed."
LSI SAS616x series switches are based on enterprise-hardened LSI
silicon, firmware and software. The model SAS6160 and SAS6161 switches
feature a rack-mountable 16-port, 1U profile in respective half-width
and full-width form factors for quick and easy installation with
rack-mounted servers and are fully compatible with existing SAS
infrastructures. Both models feature 24Gb/s SAS connections on 16 x4 SAS
lanes to deliver an aggregated bandwidth of 384Gb/s. Each model
supports SAS and SATA connectivity to more than 1,000 devices, enabling
customers to take advantage of larger SAS topologies and tiered storage
LSI SAS616x switches offer complete SAS domain management including
port configuration, zoning, firmware management, diagnostics and viewing
of the SAS topology. High-availability applications can be supported by
using two switches with redundant data paths.
"Leveraging our expertise and technology leadership, we are
delivering the industry’s first high-performance SAS switching solution
for extending DAS environments," said Steve Fingerhut, senior director
of marketing, Storage Components Division, LSI. "With fully integrated
management software and extensive end-to-end interoperability testing,
customers are assured of plug-and-play simplicity when deploying SAS616x
series switches into existing SAS-based environments."
Since the inception of SAS, LSI has shipped over 18 million SAS-based
products across its industry-leading portfolio of controller ICs,
expanders, host bus adapters, MegaRAID® and 3ware® RAID controller
cards, RAID-on-Motherboard (ROMB) solutions and storage systems. By
offering best-in-class SAS technologies, assured interoperability and
single vendor support, LSI is the silicon-to-systems supplier of choice
for OEMs that want to deliver a broad set of storage solutions.
Production quantities are expected to be available to OEM customers
in the second half of this year.
