bought this with a refurbished HP Mellanox 10GBE card. but actually i think i could use almost any sfp+; Mellanox doesn't seem to vendor block its sfp+ modules (Broadcom/Qlogic does; Intel does; Cisco does; a lot of these baddies do, sigh). I put "mikrotik" sfp+ in my Mellanox and it worked too. Using it on Linux gets me close to transfer speeds with standard i5 and i7 systems. Good business.
