IBM and HP move towards green data centres
IBM announced enterprise additions to its Project Big Green this week, a week after HP announced its Sustainability Laboratory. Both vendors have a history of interest in this area, but HP has achieved a higher profile for its efforts. The HP announcement included long-term data centre issues while IBM concentrated on new product releases to help in this area. However, there were large areas of agreement and overlap in the two presentations, and both said that energy use has become a high-level concern for enterprises, which will grow in importance. Both see an immediate opportunity for savings in energy use with a strong financial investment case through monitoring and intelligent control systems. IBM talks of the payback period from investments in this area being less than two years. Both back these claims with case studies, although at this early stage these are thin on the ground at present. The environmental payback period may be longer where this involves hardware replacement.
