I don't know about those specific cards offhand, but a quick Google
search found a manual (
http://www.mellanox.com/related-docs/user_manuals/ConnectX-2_EN_user_manual.pdf
)
for Mellanox ConnectX-2 that explicitly mentions the use of 10G SFP+
modules in multiple locations in the document.


Just to clarify, while many people use the terms GBIC, SFP, and SFP+
interchangeably, they are not actually the same thing.

(Note that measurements below are rounded from the spec.)

GBIC is a standard developed for gigabit connectors
(hence the name "GigaBit Interface Converter).
A GBIC is 10mm H x 31mm W x 57mm D.

SFP is a standard also developed for gigabit connectors,
with one of its primary goals being that it is smaller than
GBIC and can therefore be packed into the same chassis with
greater port density (hence the name Small Form-factor Pluggable).
An SFP is 9mm H x 13mm W x 57mm D, less than half the width of a GBIC.

SFP+ is the same size as SFP, but allows rates up to 16 gigabits per second
(though 10 gigabit is what is typically used for IP networks; 16 gigabit is
used for FibreChannel.)
Many manufacturers make their SFP+ (10G) slots also support
SFP (1G) modules, but that is not a requirement.

In theory, you *should *be able to use any SFP+ module in any SFP+
slot. In practice, different manufacturers sometimes have implementation
issues with interoperating with other company's hardware. (I know someone
who just
had this problem, and it was very difficult to deal with.)
