The server comes with dual Intel Xeon Scalable processors, providing up to 76 CPU cores and 228 threads for exceptional computational power.

The server comes with 1TB of DDR4 ECC registered memory, expandable up to 16TB, ensuring ample memory for even the most demanding AI and ML workloads. It also includes 2 x M.2 2280 NVMe SSD slots for fast storage, and 2 x 3.5"/2.5" HDD/SSD bays for additional capacity.

The Supermicro SYS-4028GR-TR2 includes a range of advanced features, including IPMI 2.0 for remote management, redundant power and cooling, and support for Supermicro's Easy Management Engine (EME) software. It also includes built-in BIOS flashback functionality, allowing for BIOS updates without the need for a CPU or memory.

Overall, the Supermicro SYS-4028GR-TR2 4028GR-TR2 GPU Server is an ideal solution for data centers and research facilities requiring high-performance, scalable, and power-efficient infrastructure for AI and ML workloads. With its robust design, expansive GPU support, and advanced management features, this server is sure to meet the demands of even the most complex and data-intensive applications.

The Supermicro SYS-4028GR-TR2 is a single root GPU server designed for AI and machine learning workloads. Here are some pros and cons to help you make an informed decision about purchasing this server:

Pros:

1. High GPU Density: The server supports up to 125 GPUs, making it an ideal choice for large-scale AI and ML workloads.

2. Reliable and High-Performance: Supermicro is known for its reliable and high-performance servers. The SYS-4028GR-TR2 is no exception, with features designed specifically for AI and ML workloads.

3. Scalability: With its high GPU density and support for multiple GPUs, the server can easily be scaled to meet increasing computational demands.

4. Flexible Configuration: The server supports a range of GPUs and can be configured to meet specific requirements.

5. Energy Efficient: The server features a 2kW power supply, which is energy efficient for a server of this size and GPU density.

Cons:

1. High Cost: With its high GPU density and advanced features, the server comes with a high price tag.

2. Complexity: The server is designed for advanced AI and ML workloads, making it more complex to set up and manage than a standard server.

3. Limited Expandability: While the server supports a large number of GPUs, it may not be expandable beyond its current configuration.

4. Cooling Requirements: The server requires a large amount of cooling to maintain optimal temperatures, which can add to the cost and complexity of the system.

Conclusion:

The Supermicro SYS-4028GR-TR2 is an excellent choice for organizations with large-scale AI and ML workloads. Its high GPU density, reliable performance, and energy efficiency make it a top contender in the market. However, its high cost, complexity, and limited expandability may make it a less attractive option for smaller organizations or those with more modest computational needs. Ultimately, the decision to purchase the SYS-4028GR-TR2 will depend on the specific requirements and budget of the organization.

Recommendation:

If your organization has large-scale AI and ML workloads and a significant budget, the Supermicro SYS-4028GR-TR2 is an excellent choice. Its high GPU density, reliable performance, and energy efficiency make it an ideal solution for these workloads. However, if you have more modest computational needs or a smaller budget, you may want to consider alternative solutions with lower GPU density and lower cost. Additionally, if expandability is a priority, you may want to consider servers with more flexible expansion options.

Details:

GPU Pie Architecture AI-Critical: Single Root Complex topology. Verified Low Usage Important: A SATA SSD that lived in this system since it was purchased new checked via SMART diagnostics: 125 power-on hours. Shipping / Pickup: Buyer pays shipping. Disclosures Fully Transparent: CPU cooler clearance:The installed coolers block the two DIMM slots immediately adjacent to each CPU.This is visible in photos and can be resolved with lower-profile if full population desired.

Ideal for datasets, scratch disks, or tiered storage. Flexible airflow configurations. 10 cores / 20 threads per CPU. Supports consumer or data center GPS.

Fan wall, back plane, and internal cabling. Designed for sustained, full-load GPU operation. Please review all photos and feel free to reach out with technical questions. Virtualization accelerator workloads.

As a result, this server has seen extremely light real-world usage and was not operated as production or data center system. Required for: Multi-GPU training. Back plane installed. Cosmetic: Minor cosmetic scuff on power button functions normally.

Exceptionally low usage. See photos for exact condition. RDMA-capable architecture. Drive trays minus screws for two.

Air shroud included for correct GPU airflow. Headless deployment. Condition: Used Fully functional. Dual Intel Xeon Cups.

RDMA / GPU Direct workflows. Rails Included: Original SuperMicro rack-mount rails included. 99% drive health. This is a true enterprise GPU platform, purpose-built for AI, machine learning, deep inference, CUDA workloads, and HPC, with the correct Pie topology, power delivery, airflow sustained operation.

Home lab power users. Optimized for Pie band width and I/O throughput, making this an ideal GPU host platform. Research labs universities. This chassis was designed from the ground up for dense GPU acceleration, not retrofitted from a generic server.

Ideal For: AI / ML startups. This corroborates that the system was powered on primarily for testing and validation, not continuous production use. See SMART screenshot in photos.: CPU Compute Configuration: 2 Intel Xeon E5-2650L v3. IT departments. GPU peer-to-peer communication.

PM Bus enabled. No functional issues. Large DIMM capacity makes this platform well-suited for economical AI workloads, in-memory datasets, virtualization, and containerized environments, especially under current DRAM supply constraints. CUDA GPU compute.

UPS Ground or FedEx recommended. Power control. Shortly after purchase, I transitioned into a full-time tech role and never fully deployed the system.
