I use balance mode0 on my gluster servers - but it doesnt exactly work as you would expect it too. We run Cisco 4948g switches (48 port gigabit) and our gluster servers have two gigabit links bounded together using mode0. Balance mode0 does a great job of balancing outbound traffic however the Cisco's always routes each single INBOUND tcp connection traffic down a single trunk. So the only way to really gain an advantage is to use multiple tcp connections between the many hosts - or in the case of gluster using multiple bricks per server striped together. liam On Tue, Jan 5, 2010 at 7:20 AM, Adrian Revill <adrian.revill at shazamteam.com> wrote: > Hi > > I am looking at which is the best bonding mode for giagbit links for the > servers.
