has anyone ever configured one multi vif across 4 GBE interfaces? Is there anything to watch out for? I read rumors (can't find the source anymore) that the hashing algorithm to do the load sharing might badly impact performance.
Somehow I have not been able to find anyone that ever had a need for more in 2 GBEs in one multi vif, but the one exception of having one single vif across two switches and having on each switch a multi vif with 2 GBE interface ... clear as mud, right?
I've got two 960s, each with 4 GBE's in a multi-vif. using IP load balancing, all four interfaces can get plenty busy. 4 GBE interfaces ane needed on a 960, btw, because they can sustain 250 - 350 Mbyte/sec of read, at least with my workload.
for splitting the vifs acriss switches, I think you need to make two 2-GBE vifs, and then a third vif that contains the other two. netapp calls these "second-layer" vifs.
