Data Center Network Architecture Framework
Design resilient data center networks with architecture frameworks and vendor evaluation
What You Can Do
You can structure complex data center network designs from scratch by combining resilience frameworks, capacity models, and vendor comparison templates. You'll evaluate competing architectures based on cost, availability, latency, and scalability, then produce detailed decision documents that justify your design choices to stakeholders and engineering teams.
Features
Structured decision trees for designing fault-tolerant architectures with redundancy layers, failover mechanisms, and failure scenario analysis
Calculate bandwidth needs, latency budgets, and throughput requirements based on workload profiles and growth projections
Evaluate leaf-spine, traditional three-tier, and mesh designs against your specific performance, cost, and operational requirements
Structured templates for comparing switches, routers, and solutions from major vendors (Cisco, Juniper, Arista, etc.) on features, pricing, and support
Calculate total cost of ownership (hardware, power, cooling, staffing) and compare architectures by ROI and payback period
Identify bottlenecks, oversubscription risks, and optimization opportunities in your proposed design using flow modeling
Define RTO/RPO targets, failover strategies, and backup network paths to meet availability SLAs
Align your architecture with regulatory requirements (GDPR, HIPAA, PCI-DSS, FedRAMP) and audit frameworks
Example Output
Example 1: Leaf-Spine Architecture Design
Core Spine Layer: 8x 400G switches (redundancy)
Access Leaf Layer: 48x 100G switches
Redundancy: Full mesh connectivity
Bandwidth: 3.2Tbps aggregate
Latency: Sub-100ms East-West
Availability: 99.99% uptime (dual-path)
Example 2: Vendor Comparison Matrix
| Feature | Cisco NX-OS | Juniper Contrail | Arista EOS |
|---|---|---|---|
| Max Port Density | 768 x 100G | 864 x 100G | 768 x 100G |
| ASIC Latency | 350ns | 280ns | 250ns |
| License Cost (3yr) | $180K | $145K | $120K |
| Power per Port | 8.5W | 7.2W | 6.8W |
Example 3: Capacity Forecast
Year 1: 2.5 Tbps utilization (78% capacity headroom) Year 3: 5.8 Tbps utilization (upgrade spine to 6.4Tbps) Budgeted CAPEX: $4.2M (phased over 36 months)
