Green IT 'is based on data demands'
27 Aug 2008
Companies typically take their data storage demands into account when procuring green IT equipment, it has been asserted.
Blocks and Files columnist Chris Mellor suggests that the requirements of a data storage environment play a greater part in determining which products are chosen than the eco-friendliness of the equipment itself.
"You don't buy green storage per se - you decide on a storage strategy for particular data and then buy storage for that data," he explains.
Mr Mellor adds that new standards to be introduced in order to indicate the greenness of different storage solutions could prove difficult to make "meaningful".
He points out that the desire to create a "level playing field" could leave some elements of eco-friendly design - such as virtualisation or Maid arrays - outside of the specification as they are not included in all devices.
Previously, Hu Yoshida, chief technical officer at Hitachi Data Systems, suggested that omitting such features could result in devices with energy-efficient ratings actually harming the environment more than those with no ratings but with additional functionality.
