Hi Ivo,
I don't have any experience with the Dell switches but what about the Arista DCS-7050QX-32 or DCS-7050QX-32S?
32x40G QSFP+ for the 7050QX-32
32x40G QSFP+ of which one QSFP+ can act as a dual personality to 4xSFP+ for the 7050QX-32S. (mind the S)
There are converters for the QSFP+ to turn them into a SFP+ port if you need more 10G but want to have a way to migrate to 40G.
You can do this with the Mellanox 655902-001 QSA adapter.
Which is pretty much what we have in production. :)
Are you planning to buy new or eBay? There are some pretty good deals on eBay.
