Only receptacles that support 6 Gbps over a 10 m cable are support to have
that key slot. If the phy's ability to support 10 m cables at that rate is
questionable, then not including that key slot is safer.
A 10 m cable without that key leaves itself open to being plugged into
receptacles where it won't work reliably.

Subject: SAS2 6G Connectors
In looking at SAS-2 it appears that all external connectors that support 6G
are supposed to have slot 3 on the connector. Likewise the cables are
supposed to have key 3 if they are for 6G (i..e, too long for 3G). Yet when
searching for cables and HBA's on the web, we do not see any cables or HBA's
that have key/slot 3.
Am I missing an understanding here?
