This document discusses Planet Filestore, a tiered storage project at Cardiff University that aims to reduce energy consumption by automatically migrating data to different storage tiers based on access time. It provides recommendations to calculate energy and cost savings from adopting tiered storage. Different types of university users are described along with their storage usage. The document promotes continued dissemination of the project and an upcoming tool to help model tiered storage implementations. It concludes by inviting feedback and questions.

- 1. Planet Filestore and the StorC Project Paul Rock Information Services Cardiff University
- 2. How much Power do Idle Disks Consume? NB: These disk arrays do not have “spin-down” features.
- 4. Tiered Storage as used in Planet Filestore
- 5. Choosing Data Migration Criteria ➢Start simple and conservative ➢Used “Accessed Time” if you can... ➢ But often you can't
- 6. What we used for Planet Filestore
- 7. Different Kinds of University User ●Group A is mainly administrative staff (993GB) ●Group B is our Information Services directorate (287GB) ●Group C mainly consists of undergraduate students (79GB) ●Group D is a large research school (615GB) ●Group E is a small cross-disciplinary research group (31GB)
- 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 StorC Project ➢
- 12. StorC Project StorC Project ➢ ➢ JISC project started in Feb 2011 ➢ Web based modelling tool to help to build a case for adoption. ➢ Industry default values – or customise with your own ➢ Available as a service on the UK Access Management Federation ➢ You can return to your work later to continue or show it to your boss.
