3. **Reliability**: 
   - Persistent handles survive 99% of network interruptions
   - Witness protocol achieves <5 second failover time
4. **Compatibility**: Works with Windows Server 2016+ and Azure Files

## Next Steps

1. **Immediate Actions**:
   - Set up Windows Server test environment
   - Create detailed technical specifications for Phase 1
   - Identify and evaluate Java RDMA libraries

2. **Phase 1 Kickoff**:
