This is one of the key reasons that link aggregation is easier. You don't need to have the interfaces plumbed with IP's in the control domain or have your guests run IPMP. In the guests, you only need one VNET per network. Of course the downside is that you need a switch that supports LACP. Now a more complicated configuration would be to have a control domain and another service domain, both running link aggregation and the guests running IPMP to handle control/service domain failures.

OK picture this. you have a domain controller with two interfaces e1000g0 and nxge0 both are on the same vlan 192.168.1.x joined together with IPMP. active interface is e1000g0. we have two different LDOMS that are going to be using this network LDOMa and LDOMb. each LDOM has 4 zones under it. This gives us five vnets on each LDOM ten in total. Since IPMP is active/passive all of your traffic from ten different vnets is going down your e1000g0 pipe. now lets say we do our IPMP down inside the LDOMS/zones this would require that I create 5 vnets on LDOMa under e1000g0 and 5 vnets on LDOMa under nxge0. 5 vnets on LDOMb under e1000g0 and 5 vnets on LDOMb under nxge0. Now down inside the LDOMS/zones I alternate between which vnet is the primary. This allows me to double the network bandwidth down inside the LDOMS/zones than doing all of the IPMP at the domain controller level. Next: My environment has 4 to 6 LDOMS on a given domain controller all running 4 zones inside of them. Each of the LDOMS is tied to a vlan that I do not want or need on the domain controller. I do not want a interface plumbed up on the domain controller just to run IPMP on it instead of the LDOMS. -- This message posted from opensolaris.org _______________________________________________ ldoms-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/ldoms-discuss _______________________________________________ ldoms-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/ldoms-discuss
