Chapter 1: Overview Serial Attached SCSI and the SAS6160 Switch | LSISAS6160 SAS Switch User Guide |
You can connect multiple SAS6160 switches in various topologies to provide failover support and to increase the number of connected devices in the SAS domain. The theoretical upper limit of SAS devices in a domain is 16,000. Each SAS6160 switch can handle 1000 SAS addresses.

Figure 3: Block Diagram of the LSISAS6160 Switch
This diagram contains the following functional blocks:
SAS2X36 Expander – This block includes such management functions as routing, device discovery, and zoning. It also includes an embedded version of SDM. This block controls the flow of data through the SAS connectors.
SAS Connectors – The SAS6160 switch has 16 x4 Mini SAS connectors, numbered 0 through 15. It supports connection to SAS devices at link rates of 3.0Gb/s and 6.0Gb/s.
Ethernet Phy – The external 10/100 Ethernet port provides access to the
Real Time Clock – The
Fans – The SAS6160 switch enclosure contains two fans. The fan speed is regulated based on the temperature inside the enclosure. You can monitor the status of the fans with the SDM utility.
