The tiered approach balances speed, capacity, and data protection needs. Review Storage Technologies for a comprehensive overview of different storage options.
Networking
High-speed networking is critical for transferring data between servers and clients.
- **Ethernet:** Dual 100 Gigabit Ethernet (100GbE) ports with RDMA support.
- **Interconnect:** Mellanox ConnectX-6 DX network interface cards.
This configuration allows for minimal latency and high throughput data transfer, reducing bottlenecks during file transfer and remote rendering. See Networking Fundamentals for a deeper understanding of network technologies.
Motherboard

This motherboard supports dual CPUs, a large amount of RAM, and multiple PCIe slots for GPUs and networking cards.
Power Supply
- **Capacity:** 2000W 80+ Titanium Certified
- **Redundancy:** Fully redundant power supplies (1+1)
- **Efficiency:** >94%
A high-wattage, high-efficiency power supply is crucial for powering the demanding components. Redundancy ensures uninterrupted operation in case of PSU failure. Refer to Power Supply Units for more information.
Chassis
- **Type:** 4U Rackmount Server Chassis
- **Cooling:** High airflow design with redundant fans.
A robust chassis provides adequate cooling and physical protection for the components.
- 2. Performance Characteristics
The performance of this configuration has been benchmarked using industry-standard rendering software.
Benchmark Results
- **Blender (BMW 27):** Average render time: 18 minutes (compared to 35 minutes on a comparable consumer workstation).
- **V-Ray Benchmark:** V-Ray Render Benchmark Score: 28,500 VRay Units (VRUs).
- **Cinema 4D (Corona Renderer):** Average render time for a complex scene: 22 minutes.
- **OctaneRender Benchmark:** 8500 OctaneBench points.
These benchmarks demonstrate the substantial performance gains offered by this configuration compared to typical desktop workstations. The dual GPUs and high core count CPU significantly reduce render times.
Real-World Performance
In a production environment rendering architectural visualizations, a single server node consistently rendered frames 2x-3x faster than a similarly priced workstation with a single high-end GPU. The ability to queue multiple renders and distribute them across multiple servers in the rendering farm further enhances overall throughput. Network latency, however, can become a bottleneck if the network infrastructure isn’t adequately provisioned. Monitoring tools like Server Monitoring Tools are essential for identifying and resolving performance bottlenecks.
