Depends on the kind of performance you're after. :)

If you're just wanting something better than 10GbE at minimal cost,
these work fine under Linux:

  ~US$40 each, not counting postage

They're rebadged Mellanox MHGH28-XTC cards.  Completely ok to be
flashed with standard Mellanox firmware.

For cables, I use these:

  US$14 each, not counting postage

Note, I'm comfortable getting stuff off eBay where the seller
seems ok.  So far, so good. ;)

If you do decide to use the above stuff, and later on want a switch,
try and find a Voltaire ISR 9024D-M.  They're DDR infiniband (20Gb/s
per port), and can run fanless (completely silent).


They can be had pretty cheaply if you're willing to wait for good
pricing.  I got mine for ~US$270.

Hope that helps. :)
