ACTION - All - Read and comment on this power states issue for EMAN.<br>
<br>The latest draft of the IETF EMAN Energy Monitoring MIB (monitor-only<br>subset of EMAN model) includes the following issue:<br><br> "OPEN ISSUE 12: Consideration of IEEE-ISTO PWG in the IANA list <br> of Power State Set ? PWG Imaging Systems Power Management MIB <br>
reference."<br><br>And Bruce Nordman (EMAN co-chair) raised the question of registering the<br>PWG power states with IANA for EMAN last week at the PWG meeting <br>- I waffled in my reply.<br><br>On reflection, I propose that the PWG does NOT register their own power<br>
states (adding significant complexity to the NMS systems that will already<br>support the other three standard power state sets).<br><br>Instead, best practice would be for PWG Power MIB enabled devices to<br>*fold* vendor extension states into their base DMTF power states (already<br>
in EMAN) for more coherent power monitoring and power management<br>across the enterprise. This folding would have to occur anyway for a DMTF<br>CIM mapping of the PWG Power Model, so we'd be consistent for "outside"<br>
standards.<br><br>Comments?<br><br>Cheers,<br>- Ira<br><br>PS - I'd like to reply on the IETF EMAN mailing list within the next two weeks<br>on this issue - please send your opinions.<br><br><br clear="all">Ira McDonald (Musician / Software Architect)<br>
