ethernet bonding / 802.3ad / link aggregation
we are looking at channel bonding / link aggregation (2 x 1 Gbit/s) on our
hadoop slaves.
what is the recommended bonding mode? i found some references to mode 4
(802.3ad, hardware based) and to mode 6 (balance-alb, software based) in
hadoop mailing lists.
thanks! koert
