Dell supports multipathing with Gatekeepers, whether NMP or PP/VE. The NMP policy of Round Robin and iops=1 should be used for Gatekeeper devices.
Gatekeepers may not be shared among multiple virtual machines (such as multi-writer flag or shared SCSI bus) regardless of the multipathing software. However, Gatekeepers can be presented to multiple ESXi hosts in a cluster to enable VMware HA for the VM.
