My servers have built on-board QDR IB via QSFP :) And I didn't want/mean to start any interconnect wars. I know how those end up going. If you have 10G infrastructure then 10G is the way to go (to some size anyway before the 10G switches become either way oversubscribed, or off the chart expensive)

But OK, you caught me. The real reason I want 10GigE is because that is the infrastructure I already have. :-) - Pat _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
