4. Biodiversity vs. Techno Diversity
Can we look to the natural
world as a model for our
storage strategies?

7. Species Roles
Species
Storage technologies - Disk, tape and optical
Each species has its own role to play in the ecosystem
Disk - Performance
Tape - Capacity
Optical - Longevity
Species contain genetic variations
Disk - Fibre Channel, SCSI, SATA, SAS…
Tape - LTO, DLT, AIT …
Optical - CD, DVD, Blu-ray, UDO…

17. Techno Diversity Conclusions
Each species has a role to play
Recognize the inherent technical strengths and weaknesses
Species evolve and change
Embrace new and evolving technologies
Complex food web relationships provide resilience
Understand data types, workflow and interaction
High bio diversity creates system stability
Don’t rely on single technology strategies
Ecosystems are in a constant state of change
Expect and plan for change
Ecosystems are interdependent living structures
Build a robust environment through an understanding of business requirements and techno diversity

18. Techno Diversity Conclusions
"An archive strategy to meet today’s demanding compliance standards is a business imperative. IT executives should strive to separate fixed content data from production data and move static data to an active archive. A best practice for securing long-term data archives is to maintain three copies of data on at least two different types of media in multiple locations, mitigating the risk of media failure. At least one copy of the media should be removable and be maintained offsite for disaster recovery purposes.”
Carolyn DiCenzo, Research Vice President, Gartner, Inc.
