Hi,
SX1012 + GW license is equal to SX6012 with GW license.
The 56GbE license does not include the GW license, it give the ability to reach higher speed (56GbE) on the Ethernet links.
if you have just SX6012 or SX1012 with GW license, the Ethernet links will reach 40GbE, while the InfiniBand links will reach FDR (56Gb/s)
