Hi Liam, Yes that is a good point, i will have to check for that, as I will be moving from 3com to Cisco 5500g So far I only have 2 elderly test servers, using netperf i have measured 1600Bbits/s which seems to be CPU limited. I will look at the double brick idea as it sounds a good work arround. Liam Slusser wrote: > I use balance mode0 on my gluster servers - but it doesnt exactly work > as you would expect it too.
