Appendix A: Introduction to SAS ● 62
You can connect up to 128 edge expanders to a fanout expander.
You can use only one fanout expander in any single SAS domain (a topology of SAS—and
possibly SATA—end devices and expander devices). A single SAS domain can therefore
comprise up to 16,384 SAS ports (and therefore up to 16,384 SAS addresses).
The following figure illustrates (in very basic terms) a SAS domain and shows how SAS
controllers, SAS and SATA disk drives, and expander devices can fit together in a large data
storage topology.
How is SAS Different from Parallel SCSI?
In summary, although SAS and parallel SCSI use the SCSI command set, how they move data
from one place to another is very different. To support point-to-point serial data transport,
SAS introduces new types of connectors, cables, connection options, and terminology.
Generally speaking, SAS is faster and more flexible than parallel SCSI, and provides more
options for building your storage space. SAS lets you mix SAS and SATA disk drives together,
and lets you connect many, many more devices.
The following table describes many of the main differences between the two interfaces.
