Network Checklist
1. Network Architecture Design
Basic Network Planning
- Topology Structure Verification Confirm whether the deployment architecture (star/ring/mesh) meets the high availability requirements of distributed storage
- Redundant Path Check Ensure at least two independent physical links exist between nodes
- Bandwidth Planning Calculate estimated traffic: Object storage read/write bandwidth × Number of nodes × Number of replicas + 20% redundancy
IP Planning
- [ ] Separate management network from data network
- [ ] Assign consecutive IP segments for storage nodes (recommend /24 subnet)
- [ ] Reserve at least 15% of IP addresses for expansion
2. Hardware Equipment Requirements
Switch Configuration
| Check Item | Standard Requirements |
|---|---|
| Backplane Bandwidth | ≥ Full port line-speed forwarding capacity × 1.2 |
| Port Type | 10G/25G/100G SFP+/QSFP+ fiber ports |
| Flow Table Capacity | ≥ Number of nodes × 5 |
| Spanning Tree Protocol | Enable RSTP/MSTP fast convergence |
Physical Connections
- [ ] Fiber attenuation test (single-mode ≤0.35dB/km)
- [ ] Port misalignment connection check (Node A eth0 ↔ Node B eth0)
- [ ] Cable labeling system (including source/destination IP + port number)
3. Operating System Network Configuration
Kernel Parameter Tuning
bash
# Check the following parameter settings
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_keepalive_time = 600
net.ipv4.tcp_slow_start_after_idle = 0Network Card Configuration
- [ ] Enable jumbo frames (MTU=9000, requires full path support)
- [ ] Verify network card bonding mode (LACP mode4 recommended)
- [ ] Disable IPv6 (if not needed)
4. Security Policies
Firewall Rules
bash
# Required open ports
- TCP 443 (HTTPS API)
- TCP 9000 (S3 compatible interface)
- TCP 7946 (Serf node communication)
- UDP 4789 (VxLAN tunnel)Access Control
- Switch port security MAC limitation
- IPSec tunnel encryption between storage nodes
- Enable TLS 1.3 for management interface
5. Performance Verification Testing
Benchmark Test Items
- Inter-node latency test:
iperf3 -s 8972 <target IP> - Cross-rack bandwidth test:
iperf3 -c <target IP> -P 8 -t 30 - Failover test: Randomly disconnect core links and observe recovery time
Acceptance Standards
| Metric | Requirements |
|---|---|
| Node Latency | ≤1ms (same data center)/≤5ms (cross AZ) |
| Bandwidth Utilization | Peak ≤70% design capacity |
| Failover | <500ms BPDU convergence |
6. Documentation Requirements
- Network topology diagram (including physical connections and logical IPs)
- Switch configuration backup files (with timestamps)
- Baseline test reports (with raw data)
- Change record table (with maintenance window information)
Tip: It is recommended to conduct 72-hour stress testing before formal deployment, simulating 110% of peak traffic load scenarios
