NSA 3600 10Gb SFP+ Compatibility

While planning out some network upgrades, I was told that there might be some communication issues between the SFP+ ports on a Dell SonicWall 3600 and a NETGEAR ProSAFE XS748T due to a mismatch of the brands. Are the communication protocols over SFP+ really so non-standard and brand specific that they wouldn't interface properly? I was under the impression that routing protocols are standard across the board and that there aren't too many devices out there for networking that stray away from industry standards. I have already verified that the Netgear device adheres to IEEE standards and MSA certifications. Any insight into the Dell side of this?

Thanks,
Will
