Trunk/multipath your Sun NIC's to access the NetApp Filer to increase network throughput.

> At the moment there is no problems since the configuration is dead easy but I fear the network (netapp on it's own 100TX subnet) will become a bottlenet and possibly cause NFS timeouts with the Solaris machines.
