12Gb/s SAS/SATA Expander
LSI SAS3x48, LSI SAS3x40, LSI SAS3x36
Enhance your external storage environment with high scalability and
performance with LSI SAS Expanders
Overview
The 12Gb/s SAS Expanders are LSI’s seventh generation of expanders that incorporate the
latest enhancements in SAS technology. The 48, 40, 36-port option expanders are designed
with an integrated ARM Cortex-R4 processor for topology management functions such as
discovery, enclosure and drive management, and LED management. The expanders support
SAS data transfer rates of 12, 6, 3 Gb/s, and SATA data transfer rates of 6 and 3Gb/s.

The LSI SAS expanders also incorporate the latest enhancements in SAS technology which
includes Spread Spectrum Clocking for EMI reduction and T-10 based zoning for network
storage security applications. Other innovative, unique features include DataBolt
™
Bandwidth
Optimizer. DataBolt
™
Bandwidth Optimizer 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 drives and backplanes. The expander buffers 6Gb/s data and then
transfers it out to the host at 12Gb/s speeds in order to match the bandwidth between faster
hosts and slower SAS or SATA devices. Additional features such as Port Mirroring allow the
customer to access signals that are not easily accessible by mirroring that signal to an external
connection for debug and diagnosis. The SATA affiliation option allows for turning off all
affiliations and allowing multiple hosts to control various SATA drives.
For improving system reliability for today’s data center and storage subsystems, the LSI SAS
expanders are ideal for connecting multiple targets and hosts in a SAS switched environment.
This will support scalability and fault- tolerant path-redundancy.
