The HP boxes have Broadcom ethernet controllers driven with the 'bge' driver, and thatw orks fine. I stick to Intel or Broadcom controllers for gigabit ether where I have a choice. The only 10 gig cards we have are some 2nd hand Mellanox ConnectX-2 cards because they are dirt cheap on eBay. They work fine in FreeBSD using the mlxen driver (add MK_OFED=yes to tour /etc/src.conf) but we have had a lot of problems getting them to talk to anthing other than other identical cards - a set of Qlogic (I think) HP cards would work very occasionally, but most of the time would not find a carrier. We are using twinax copper SFF+ for the 10 gig, maybe I would have got better luck with optical, but it wasnt importnat enough to do any serious testing on. -pete.
