Rob- Did you mean 10m or 6m for key slot 3?

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.

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?
