Application Examples
Single Expander Example
The LSISASx12 can be used in simple topologies to attach an initiator
to SAS/SATA devices, in edge expander topologies to increase the
number of accessible devices, or in fault-tolerant path-redundancy
topologies to improve system reliability. By cascading multiple
LSISASx12 expanders, users can attach up to 144 devices.
The LSISASx12 expander can be used to construct many different SAS
topologies. A few examples are shown in the following subsections.
Simple topologies can utilize a single expander to access SAS or SATA
drives as illustrated by
