Video : "Power Management with Oracle VM Server for SPARC"

Thursday, July 5. 2012

Nice video showing the concepts of power saving in T4 systems like performance and elastic power management policies, how cycle skipping is handled by the LDOM manager, shows the power management on the memory, how ldom managers switches off cores while in elastic mode.

You can view the video here.

Nice video. I wonder if its possible to manage those power settings more in detail with the ldm itself rather than only in the HW level?
Would it be possible to give some ldom guests different powersaving-policies than others?

There's another recent sun4v video that I found most interesting:

This demonstrates cross-CPU migration with OVM for SPARC v2.2.
Watch carefully (hint: especially between 0:18 and 0:36)
...and tell me if you see anything notable. =-)
