Check Your Storage Environmental Footprint

Big data, machine data, copy data, hot data, cold data, metadata. If nothing else we are all data creators, copiers, hoarders, posters, likers, tweeters and information junkies. Cloud or not, it all gets stored somewhere on something physical using power and taking up more and more space. So how do you really ever know the impact on the environment?

Long before there were standards for energy efficiency, Hitachi initiated its own Design for Environment (DfE) to address the efficiency of its products. The environmental load is evaluated throughout the product life cycle - from material procurement to production, distribution, use, collection and dis-assembly, and appropriate disposal-is assessed using eight criteria, including environmental protection measures and energy savings.

Internal classifications were created primarily for the Japanese market. Termed Eco-Products, the results are recorded as 1 through 5. For a product to be designated an Eco-Product, it must score at least level 2, the reference level before the latest major model change, in all eight assessment criteria and its average over all the criteria must be level 3 or higher.  Eco-Products Select must have either a global warming prevention factor or resource factor of 10 or more, or be leaders in their industry for their energy efficiency, or have received an award outside the company or official certification for their environmental excellence, or have a CO2 emission reduction rate at least 50 percent greater than fiscal 2005 products.

In addition, the company actually reports on the status of this initiative in terms of a sales ratio. Currently 89% of the products sold have been through this process. The company measures the improvement in quality of life by product function and life span, and use the amount of greenhouse gases emitted over the product life cycle to calculate the reduced environmental load. The environmental report is independently audited.


All well and good, but how do you know what you are purchasing? Hitachi publishes data sheets for the environmental impact of it's storage products. For example, the VSP G200 is classified as an Eco-Products Select. This model emits 40% less greenhouse gas compared with the reference product AMS200. Ask your vendor about their environmental impact, and compare where you store your data.
