Can someone please give me a suggestion for the best setup?

Cluster with 4 physical servers should run about 20 KVM machines and a few openvz ones

we have also a netapp iscsi Store actal in use, but performance seems bad
 
do you have a fast network dedicated to iSCSI? slow iSCSI can have multiple reasons.
 
each server of the cluster has one NIC connected via VLAN to the Netapp and one NIOC connected to LAN

All Network connections are 1Gbit
 
so you have no dedicated physical network for iSCSI - maybe a point to start.
