Yes - just look at the fastest cluster in the world, Roadrunner. It uses Infiniband to access the Panasas parallel file system. In that architecture there are storage routers between the Infiniband and the Panasas. I'd imagine that TACC Ranger runs Lustre over Infiniband. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
