For copper gigE I've never had a problem with the Intel Pro-1000 series of cards. They just work. For gigE cards with optical connects I've had success with both Intel Pro-1000 and SysKonnect.

They may have news or recommendations to report that are specific to your brand of motherboard, PCI slot etc. -Chris Malay Kumar Basu wrote: > Hello Cluster gurus: > > I have almost finalized buying of hardware for my cluster except the > gigabit ethernet card.
