When developing your tiered storage strategy, one must focus on the specific needs of the organization. Many organizations have different regulations and directives controlling data lifecycle management practices. Here are some factors you will need to keep in mind while deve
loping your own tiered storage strategy:
- Goals and Priorities
What are your goals and priorities? Improve performance? Reduce costs? Increase data access speeds?
- Determine RPO and RTO
RPO (Recovery Point Objective) is the amount of data at risk between data protection events. It reflects the amount of data that could potentially be lost during a disaster recovery. RTO (Recovery Time Objective) is the point in time when all data must be restored to resume processing
- Evaluate and Categorize Data
Determine the various types of data and understand how your organization uses it. Categorize data by type, value, retention schedules, access speeds, frequency of use, etc. Take an inventory of the applications in use to better understand your storage requirements.
- Align Data with Storage Tiers
Determine the number of Tiers and align data with the appropriate tier and media.
