The federal Environmental Protection Agency has now started down the road to developing an Energy Star spec for storage equipment. Late last month, the EPA released the first version of its Energy Star spec for servers, and it continues to work on making enterprise data centers more efficient. (At least for now, it seems that most data center managers are indifferent to Energy Star for servers.)
This week the EPA released a framework document for Energy Star storage equipment. Among other things, it looks like the spec will cover direct attached storage (DAS), network attached storage (NAS) and storage attached network (SAN), hard disk, tape, optical, solid state, hybrid storage, and bladed storage. The EPA has a dedicated Energy Star site for storage if you want to check it out.
