SSD Array Controller
RAID + ECC Controller for SSD Array
RAID + erasure-coded ECC controller managing SSD array with redundancy, scrubbing, and graceful drive replacement.
Purpose
RAID + erasure-coded ECC controller managing SSD array with redundancy, scrubbing, and graceful drive replacement.
Context
Child of L2-DVT-DIGI within the Lunar Ark system
Principles
- ▸RAID-6 + erasure coding tolerates multiple drive failures
- ▸Periodic scrubbing prevents bit rot accumulation
- ▸Hot-swap drive replacement
- ▸Per-drive SMART monitoring
- ▸Long-mission failure prediction
Typical implementations
- ▸Industrial RAID controllers (LSI/Broadcom)
- ▸NASA spacecraft mass storage heritage
- ▸ESA storage RAID systems
Lunar considerations
- ▸Coordinated with L3-DVT-INTEG-SCRUB
- ▸Long-mission firmware updates
- ▸L1-MNT drive swap protocol
