so, the answer is: with the right cables (40G to 4X10G) you can do that.
with 1036 you can get to up to 64 10GE ports.
work with this:
as far as the above relationship with gateway functionality, at this point if you want to use gateway, you can only use ports 1-8 for Eth and the rest for IB. means, with splitter cables you can get now: 110Gb (2X4X10+3X10). all the rest are IB ports.
Thanks
