What’s a SAS Connector?
A SAS connector is the physical plug or receptacle that you see on a SAS
device. It supports the power and signal line cable. It’s what you plug a
SAS cable into, or the end of the SAS cable that’s being plugged in.
A connector is what forms physical links between phys.
Some SAS connectors can support multiple links. The number of links
a SAS connector can support is referred to as its width. Narrow
connectors support a single link; wide connectors support up to four
links.
A single SAS device may have one or more connectors. A single SAS
connector may help form links between more than two SAS devices.
(For instance, as shown in the figure above, the 4-wide internal SAS
connector forms links with four independent disk drives.)
