We have two shared uplink sets, one per VC module:
Inside VC, we have created two virtual connect networks per VLAN and assigned each VCnet to one of the shared uplink sets. That way, we have the system running active-active on the uplinks.
The servers then are configured to run in active-passive and we have configured alternate preferred network card (vNIC) to kind of load balance between the two pairs of networks.
Each SUS (2x 10Gb links in a single LACP bundle) goes to one VSP9000 switch. We're not splitting a SUS across both switches, so we're not using SMLT, just a normal MLT. There is then the IST linking the two switches, and from a L3 perspective, it's basic HSRP where one switch has a higher priority than the other.
In order to simplify the above VCnet configuration, we were considering just using one pair of 10Gb-allocated FlexNICs and tagging all traffic in it. And that would include the management, vmotion, etc. Instead of cutting up the 10Gb LOM bandwidth at the VC level which isn't that flexible, we would then use the network management tools within the VMware vDS.
