How much Energy can we Save?
Key Recommendations of Planet Filestore➢Calculate what environmental and economic savings can be made by adopting an automated tiered storage approach. ➢ Calculations based on manufacturers’ stated figures are normally sufficient.➢Disks should only be installed as required to minimise the amount of energy used by idle disks. ➢ Unless storage array has spin-down features.➢Consider whether appropriate similar technology may be applicable for other applications.
So What Now?➢Continued dissemination➢Implementation at Cardiff University ➢ Rollout in production during 2011StorC Project➢
