we have a very strange behaviour. A server got an application and data on iscsi volume and it seems that when the application is invoked, the bandwidth occupation raises reaching the limits and we can see Giga tranfers (like 90MB/sec) even if the application doesn't need such traffic.
On Netapp we can see this bandwidth occupation and very high CPU levels.
The only thing that is suspect, is that on Netapp we have 2 Nic's on the same subnet.
Do you guys thinks this could cause retransmissions or strange behaviour on NetApp to justify the big amount of transmissions on server side?
