We bought the Intel x520-DA2 cards as they gives you the flexibility

using short range fibre and the optics for the other end can get
expensive!
NB; Their is a whole world of compatible optics out there which are
just as good but wont have support from the switch vendor and will
need careful testing with your kit..
If you get the DA2 card, also buy a couple of the Intel optics which
when added to the order cost the same as the SR2 and you end up with
exactly the same product, but with the flexibility of being able to
use 'SFP+ Direct Connect cables', SR optics, LR optics etc..

We bought the optics for the link to the WAN provider, and SFP+ Direct
Connect cables for the link to our HP 8206zl switches.
Intel cards support most of the official branded Direct Connect cables
(don't get real cheap ones) so get Cisco branded as you have a Cisco
switch.. Much cheaper than Cisco optics but the same end result.

Unfortunately on the Cisco part I don't SFP+.
I have XENPACK option only which give me 3 options:
SR ~ 3K GPL
LRM ~ 1.5K GPL (I can't find any LRM GBIC for Intel side)
CX4 ~ 600 GPL
I'm going probably for the CX4 option so I have to find an Intel server
card that has CX4.
My options for CX4 so far look like these:
82599EB which support all kinds of interfaces. I don't know if this is a
server adapter or not (looks very cheap)
Also it might need an CX4 interface to be attached.

Is 82599 chip the same on all the adapters? (EN, EB, X520, X540). Is it
the same card
with different optics?
Also there is this NetEffect Ethernet Server Cluster Adapter CX4
http://ark.intel.com/products/55362/NetEffect-Ethernet-Server-Cluster-Adapter-CX4
but I don't know OpenBSD's support on this. Also it's PCIe v1.1 but
I think this is my least problem.
