**Q: Will this work with a mellanox hpe 764285-b21?**
A: I can't speak specifically for that Mellanox switch.  But they are working great in my Arista switches, even if I buy I the Cisco labeled cables from 10Gtek. I think its worth a shot if it is a standard QSFP+ SR4 port and with Prime, you can return them.  Hope this helps...
