Hi Barry,
I don't think we need another one, I missed the fact that there was the
"far side managed parameter". It should be sufficient, provided the
vendors program other things correctly, such as the supported speed (^G
vs 12G)
Best,
Gourgen

Gourgen,
My interpretation of the identifier table value is that it applies ONLY
to the end directly connected. Your table 19 proposal appears to expand
the scope of the identifier table entries to the characteristics of the
entire assembly. We already have the "Far Side Managed" parameter (byte
110, bit 3) indicating that the far-end side of the cable is NOT
managed. Why do we need another bit?

It's just going to be for 6G?
We'll need to make sure this is reflected in the management interface,
SFF-8636 (since one side will be managed, and one side won't be).
Something like this:
If we want it for 8X too, we'll need to free up one more field.

"Molex proposes adding an external cable variant to SAS-3 that would
enable connection between a SAS product which incorporates a mini SAS HD
external connector to a SAS product that incorporates a mini SAS
