Hi Julien,
The DELL engineer set up the switch for us initially and we haven't altered the storage heartbeat settings since. Also according to this document from DELL - http://en.community.dell.com/dell-groups/dtcmedia/m/mediagallery/19997606/download.aspx storage heartbeat should use VMkernel.
Regarding the paths, an EQL PS4100 array only had one active controller at any time which means only 2 paths are available, unless I'm missing something there.
We have 1:1 port bindings for vmk2/3 for the iSCSI VMkernel ports.
We have 2 DELL Powerconnect 6224 physical switches that are stacked using a stacking cable and act as one switch when stacked this way. The switches were also set up by a DELL engineer. Here is a summary of the settings that he gave us. Looks like portfast is enabled:
