We currently use PowerPath on all hosts that are connected to our EMC DMX. We use IBM SDD on all hosts that are connected to our IBM DS8300. It looks like PowerPath can be used to manage IBM ESS devices. Can it also manage IBM DS8300 volumes? Is there a document that lists what third party arrays are supported by PowerPath? We would like to allocate devices from the DMX and 8300 and use PowerPath to manage them all.
