Yes, but then you loose the integrated Subnet Manager that is running on the switch. You will have to run OpenSM instead. > What's the best HCA card for me? You need to define your criteria (rank of what is important to you). E.g. HW/OS support vs perf vs MPI support etc > I'm considering purchasing two HP NC570C cards > (http://h30094.www3.hp.com/product.asp?sku=2603660&;), > which are based on that Mellanox chip. > Does anybody know if those cards would be functional in non-hp gear? I believe they will but can't warrantee that. Some of the AMD chipsets are broken in subtle ways (e.g. MSI won't work on "8131" - or something like that). > In other words, does HP have their own proprietary goodies in the cards > that would cause them to break in generic systems such as what I have? I'm not aware of any. HP has tested the cards/drivers/OSs on Proliants so they are known to work in officially supported configurations. ie they have documented a working set of firmware/drivers/OS versions. HP MPI and other commercial apps will be looking for that. hth, grant _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
