Artificial carbon storage on a large scale is still in its infancy; as environmentalists point out, some quite effective devices for carbon storage occur naturally-they are known as trees.

This makes it easy and inexpensive to separate out pure CO2, which for large-scale installations could be useful in the future if a carbon storage system becomes available.

With the scale-out architecture, IBM SONAS is a lucrative storage filer to satiate growing storage needs.
