The cost of energy and energy consumption per drive has been rising. It now costs between $200 and $450 per year to provide space, power, cooling and maintenance for each disk drive in a storage array. About half of that cost is environmentals. If customers can reduce the number of drives by aggressively consolidating storage from older low density drives onto newer high-density devices, the environmental savings can be very high.
Action Item: Storage managers need to become more aggressive about clearing out old storage arrays, and reduce the cycle time for replacing disk.
