Re: [Linux-cluster] Small Cluster, Port Trunking, To use switch or not?



Thanks. That will be very usefull when I start putting things together.

Did I understand this howto correctly: either way, switch or not, my
network devices need to be complient with this 802.3ad protocol if I
want to bond them.  RIght?

Well that's a bummer: I can't use  the network cards on board of my
"cheapo" motherboards, which means I have to buy 2 cards per node (
and the cheapest card with support of this
protocol was around 50$) . I guess I better forget about bonding then.
