Do all SFF-8087 cables include sideband support?

Sorry for the dumb question.

I'm getting close to buying my first storage chassis with a SAS expander and I'll need the SFF-8087 cables to connect the expander to the backplanes. There's a good chance I'll get a chassis with backplanes that support SGPIO and that means I would need cables that are able to carry that signal around.

Do all SFF-8087 36-pin miniSAS cables include sideband support?

Thanks!
 
I bought 2 sets of SFF-8087 Forward cables, one came with a sideband cable embedded in it, the other didnt, so no, not all Forward-type cables have the sideband cable unless explicitly mentioned.
 
nope, you gotta get sidebands on them thar cables. However, if your enclosure and controller are SES2 you wont need them pesky sidebands. Go SES2!!
 
@Computurd: Of course you need the sideband for SES2 to work properly. The sideband signals carry the SGPIO to the backplane controller that in turn controls the Error LEDs, etc. Without the sideband signals,you would have to wire the backplane separately via I2C (if the backplane and the HBA supports it) to get the controls working!
