SSD and Green IT moving beyond green washing

July 23, 2012 – 10:17 pm

Keeping in mind that there is no such thing as a data or information recession, not to mention that people and data are living longer, there is the need to discuss expanding data footprints. When researching his new article over on SearchSolidstateStorage.com John Hilliard reached out to ask about SSD, Green IT, energy efficiency and effectiveness trends and perspectives (you can read the article and my comments here).

In the past when Green IT and Green storage was mentioned, discussions focused around energy avoidance along with space capacity reduction. While storage efficiency and optimization in the context of space-saving and capacity consolidation are part of Green storage, so too are storage IO consolidation with SSD. For inactive or less frequently accessed data, storage optimization and efficiency can focus on using various data footprint reduction techniques including archive, backup and data protection modernization, compression, dedupe, data management and deletion, along with storage tiering and thin provisioning among others.

SSD and IO consolidation for Green IT and productivity

On the other hand, for active data where performance is important, the focus expands to how to be more effective and boosting productivity with IO consolidation using SSD and other technologies.

Note that if your data center infrastructure is not efficient, then it is possible that for every watt of energy consumed, a watt (or more) of energy is needed to cool. However if your data center cooling is effective with a resulting low or good PUE, you may not be seeing a 1:1 watt or energy used for storage to cooling ratio as was more common a few years ago.

The Green and Virtual Data Center book

IMHO while reducing carbon footprints is a noble and good thing, however if that is your own focus or value proposition for a solution such as SSD or other Green technologies and techniques including data footprint reduction, you are missing many opportunities.

Have a read of John’s article that includes some of my comments on energy efficiency and effectiveness to support enhanced productivity, or the other aspect of Green IT being economic enabling to avoid missed opportunities.
