Hi,

I have a pair of ProCurve 2810-24G that I will use with a Dell Equallogic SAN and Vmware ESXi. Since ESXi does MPIO, I am a little uncertain on the configuration for links between the switches. Is a trunk the right way to go between the switches?

I know that the ports for the SAN and the ESXi hosts should be untagged, so does that mean that I want tagged VLAN on the trunk ports?

This is more or less the configuration:

trunk 1-4 Trk1 Trunk 
snmp-server community "public" Unrestricted 
vlan 1 
    name "DEFAULT_VLAN" 
    untagged 24,Trk1 
    ip address 10.180.3.1 255.255.255.0 
    no untagged 5-23 
exit 
vlan 801 
    name "Storage" 
    untagged 5-23 
    tagged Trk1 
    jumbo 
exit 
no fault-finder broadcast-storm 
stack commander "sanstack" 
spanning-tree
spanning-tree Trk1 priority 4
spanning-tree force-version RSTP-operation

The Equallogic PS4000 SAN has two controllers, with two network interfaces each. Dell recommends each controller to be connected to each of the switches. From vmware documentation, it seems creating one vmkernel per pNIC is recommended. With MPIO, this could allow for more than 1 Gbps throughput.
