"I've already read it. I need more detail. I'm not sure how many ip adress must be configured in an iscsi target. I've 12 iscsi target in celerra  and 4 uplink port in vsphere host for the iscsi network. Do i need to configure 4 ip adress  in an iscsi target?"  You should have at least two IP addresses for the iSCSI target.  Can you use 4? Yes.   You should leverage two NS network interfaces that are made up of different physical devices underneath.  For example, trk0 - made up of cge0,cge1 has an IP. Then trk1 - made up of cge2, cge3 has an IP address.  The aggregated links (trk0 and trk1) should be connected to seperate physical switches.
Hello ,  we have several vsphere hosts and a celerra Ns40. We are currently using link aggregation with iscsi. we want to use  vmware native multipath. I think we need to configure an iscsi target with multiple ip address , each esx host has 4 uplink port  for the iscsi network. we have 12 iscsi target at the cellera . Do we need to configure each iscsi target with 4 ip address ? is there any detail document about vmware native multipating with celerra  ?  Thank you.
