1. **RDMA Complexity**: Limited Java RDMA support may require JNI
2. **Multi-Channel Synchronization**: Complex thread synchronization required
3. **Persistent Handle State**: Requires reliable state persistence mechanism
4. **Backward Compatibility**: Must maintain compatibility with SMB2/SMB1

### Mitigation Strategies
1. Implement features behind configuration flags
2. Provide graceful fallback mechanisms
