Q:

Sonata Admin Bundle and roles may explain to me how it works

It's the first that i use the Sonata Admin Bundle. It's looks like pretty cool. 
But if somebody can explain to me something particular with the differents roles and the display. 
With a role : ROLE_SUPER_ADMIN
It's display only my entities but not the sidebar.
With a role : ROLE_SONATA_ADMIN
It's display in the sidebar but not my entites.
It's could be very great to merge the both. Thank you for your advices and your help.

A:

You should simply assign both roles.
ROLE_SUPER_ADMIN is from SF2, ROLE_SONATA_ADMIN is from Sonata.
