8. File Modification Dates

9. How much Energy can we Save?

10. 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.

11. So What Now?
➢Continued dissemination
➢Implementation at Cardiff University
➢ Rollout in production during 2011
