Going green on your hardware is not necessarily about consumption as it is efficiency and I think that there is much difficulty in showing that on a piece of hardware without relation to capacity, cooling, or some other meaningful output. PUE is reasonable to some extent to measure a facilities efficiency. Watts per gig or meg seems a reasonable measure for this and Force10 was talking about that ions ago, but I have to wonder why Juniper and IXIA aren't doing this in conjunction with the Green Grid. -M< -- Martin Hannigan hannigan@verneglobal.com <mailto:hannigan@verneglobal.com> Verne Global http://www.verneglobal.com <http://www.verneglobal.com/> Keflavik, Iceland ________________________________ From: Glen Kent [mailto:glen.kent@gmail.com] Sent: Wed 05-Nov-08 06:11 To: OPS Gurus Subject: Ixia, Juniper going green? http://www.lightreading.com/document.asp?doc_id=166871 I wonder what impact this would put on other vendors to turn down their power consumptions and turn, as Juniper and Ixia like to put it - Green! BTW, the specs are a little skewed because they're only measuring power consumption when the router is only forwarding traffic, i.e., there is no traffic going to CPU. Also any idea about the genesis of this ECR initiative (http://www.ecrinitiative.org/) and what their eventual goal is ? Glen
