Storage Management Software
Hierarchical Storage Management and Lifecycle System
Software managing data lifecycle, migration between storage tiers, and capacity planning
Purpose
Software managing data lifecycle, migration between storage tiers, and capacity planning
Context
Child of L2-CDH-STOR
Principles
- ▸Tiered storage migrates data between fast MRAM, flash, and archival media based on access patterns
- ▸Data retention policies manage storage capacity over 100-year accumulation
- ▸Automatic migration moves infrequently accessed data to most durable media
- ▸Capacity forecasting predicts when additional storage will be needed
Typical implementations
- ▸IBM Spectrum Scale hierarchical storage management
- ▸AWS S3 storage tiers (concept adapted for embedded)
- ▸NASA PDS (Planetary Data System) data management
Lunar considerations
- ▸100 years of operational data must be managed without filling storage capacity
- ▸Most durable storage (5D quartz, nickel) is write-once - data migration is irreversible
- ▸Data compression and deduplication reduce storage footprint
