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.
