LSISAS6160 SAS Switch User Guide Chapter 1: Overview | Connecting Devices to the SAS6160 Switch
— Four cascaded switches
— A total of 64 total expanders in the topology
The following examples show several ways in which you can connect devices to the
SAS6160 switch.
The first example (Figure10) shows four servers (host bus adapters) and five JBODs
connected to the SAS6160 switch.
Figure 10: Example 1, Multiple Servers and JBODs
A single rack can contain the switch and all the other devices. The configuration
requires nine SAS cables with a Mini SAS connector on each end. Depending on the
way in which zoning is set up for the devices, all servers could access data on all the
JBODs, or servers could be restricted to accessing a subset of the JBODs.
The second example (Figure11) shows eight servers and one RAID array connected to
the SAS6160 switch.
