Today at VMworld HP announced their the HP Insight Control for vCenter. In a nut shell, HP is adding a new tab in vCenter which allows you to quickly monitor hardware health with one button launch to iLO, SIM, or power stats. Red/yellow/green lights for many subsystems let you quickly spot hardware issues. If you are a HP customer and use SIM/ICE, then you will benefit from this integration. It’s free if you have an existing ICE license. Release date is likely January 2010.
You can see the official announce here, which has a lot more details.
