AIStor protects enterprise data through three integrated resilience layers that operate continuously without stopping production I/O: erasure coding, checksums, and intelligent healing.
Erasure coding, bit rot protection, and automated healing in one platform.
Rack-Scale Fault Tolerance
Reed-Solomon erasure coding across hosts tolerates rack-level failures with configurable parity for durability and availability.
Bit Rot Protection
HighwayHash256S checksums detect silent data corruption before serving to applications, with hardware-accelerated algorithms optimized per CPU architecture.
Automated Healing
Automatic object reconstruction begins when drives go offline, with no I/O interruption. Erasure-set awareness prevents unnecessary rebuilds during planned maintenance.
Intelligent Quorum Protection
At exabyte scale, the catastrophic scenario isn't drive failure; it's accepting writes that become unreadable after subsequent failures. AIStor's intelligent quorum mechanics block writes that would violate future read availability, failing fast instead of allowing silent data loss. This eliminates "data written successfully but now unreadable" support tickets and prioritizes existing data availability over new writes.
Write Blocking
Writes blocked when read quorum at risk
Read Guarantee
Future read availability guaranteed before write acceptance
Fast Failure
Fast failure prevents unrecoverable data scenarios
Data Priority
Existing data availability prioritized

Traditional storage fails catastrophically at scale with emergency maintenance windows that halt business-critical jobs. AIStor's resilience architecture was purpose-built for exabyte-scale AI infrastructure where hardware failures are inevitable, not exceptional.
Exascale
Proven deployment
Handles 1+ EiB with thousands of drives using hardware-accelerated SIMD encoding
180-Day
Forensic retention
Drive offline tracking enables root cause analysis and proactive replacement scheduling
Healing
Shard-Aware, Throttled Recovery
Object-level healing rebuilds only missing shards with configurable throttling to prioritize production traffic
Auto-Detected
Checksum optimization
CPU-specific algorithms like AVX2 and NEON select fastest performance per platform
Business Impact
Eliminates Data Loss
Erasure coding survives 50% drive failures cluster-wide, preventing business interruptions in multi-thousand drive clusters where failures are expected.
Prevents Silent Corruption
HighwayHash checksums provide cryptographic certainty for every byte, critical for regulatory compliance and preventing training dataset poisoning or model inference errors.
Maintains SLA Commitments
Object-level healing continues in background while serving production I/O at full speed, eliminating maintenance windows and preserving uptime during drive replacements.
Reduces Bandwidth Consumption
Intelligent healing targets only objects written during offline periods—planned maintenance generates zero healing traffic, saving hours of bandwidth saturation.
