[Lustre-discuss] Kernel Channel Bonding vs. Lustre''s built-in Link Aggregation
Hello, I am trying to figure out whether CFS reccomends using kernel channel bonding or Lustre''s built-in link aggregation to maximize Lustre''s throughput. If I have lustre''s link aggregation setup like so for OST''s, the MDS, and clients: options lnet ip2nets="tcp(eth0,eth1,eth2,eth3) *.*.*.*;" Would that provide better or worse throughput that using four-port ethernet round-robbin channel bonding? Assuming concurrent access to several large files on many OST''s. Does Lustre''s built-in link aggregation increase availability? For instance, if eth0 and eth1 go down, will Lustre be able to use eth2 and eth3 without reporting i/o errors? Thanks
