DELL PowerEdge R760 Server configurator

The Dell PowerEdge XE8640 is a high-performance 4U rack server designed for demanding, accelerator-intensive workloads. Here are its key technical specifications and intended uses:

Technical Specifications:

• Processors: Two 4th or 5th Generation Intel Xeon Scalable processors, offering up to 56 cores (4th Gen) or 64 cores (5th Gen) per processor.
• Accelerators (GPUs): It's a GPU-dense server, primarily featuring:
• Four NVIDIA HGX H100 80GB 700W SXM5 GPUs, fully interconnected with NVIDIA NVLink technology. This provides high-bandwidth GPU-to-GPU communication (up to 900GB/s).
• Some configurations may also support NVIDIA HGX A100 GPUs.
• Memory:
• 32 DDR5 DIMM slots.
• Supports up to 4 TB of RDIMM (Registered DIMM) memory.
• DIMM speeds up to 4800 MT/s (or up to 5600 MT/s depending on processor generation).
• Supports registered ECC DDR5 DIMMs only.
• Storage:
• Front Bays: Up to 8 x 2.5-inch NVMe SSD drives (maximum 122.88 TB).
• Can also support 2.5-inch SATA/SAS SSDs or E3.S NVMe SSDs.
• Internal Boot: Boot Optimized Storage Subsystem (NVMe BOSS-N1) with HWRAID 1 and 2 x M.2 SSDs for the operating system.
• Software RAID (S160) is also supported.
• Cooling:
• Air cooling for CPUs.
• Liquid Assisted Air Cooling for GPUs: This is a hybrid approach, where liquid cooling is applied directly to the GPUs, with the heat then transferred to a radiator that uses air cooling. This allows for high GPU density within an air-cooled data center environment, without requiring facility water to the rack.
• Power Supplies: Redundant, hot-swappable Titanium-rated power supplies (eg, 2800W or 3200W).
• Networking:
• 2 x 1GbE integrated ports.
• 1 x OCP 3.0 slot (x8 PCIe lanes) for additional network options.
• PCIe Expansion: Up to 4 PCIe Gen 5 slots (x16) for optimal expansion.
• Management:
• iDRAC9 (Integrated Dell Remote Access Controller) for embedded management.
• iDRAC Direct, iDRAC RESTful API with Redfish, and iDRAC Service Module.
• Integration with Dell OpenManage Enterprise, CloudIQ, and other management tools.
• Security: Features like cryptographically signed firmware, Secure Boot, Secured Component Verification, Silicon Root of Trust, TPM 2.0, and data-at-rest encryption.
• Form Factor: 4U rack server.
• Dimensions: Approximately 174.3 mm (Height) x 481.91 mm (Width) x 901.4 mm (Depth with bezel).
• Weight: Approximately 61.4 kg (135.36 pounds).

Intended Tasks and Use Cases:

The Dell PowerEdge XE8640 is purpose-built and optimized for highly demanding, accelerator-intensive workloads, particularly those that benefit from powerful GPUs and high-speed inter-GPU communication. Its primary intended uses include:

• Artificial Intelligence (AI) and Machine Learning (ML) Training: The four interconnected NVIDIA H100 GPUs make it ideal for training large, complex AI models, including deep learning and large language models (LLMs), where high GPU-GPU bandwidth is crucial.
• High-Performance Computing (HPC) Modeling and Simulation: It excels in scientific and engineering simulations, computational fluid dynamics (CFD), molecular dynamics, and other compute-intensive HPC applications.
• Data Analytics: Accelerating data processing and analytics tasks that can leverage GPU power.
• Dense Inferencing: While designed for training, its powerful GPUs can also be used for high-volume AI inferencing in scenarios like medical imaging, financial analysis, and other business decision-making applications.
• Multi-User Environments with Virtualization: Utilizing capabilities like NVIDIA Multi-Instance GPU (MIG) to host multiple users or workloads on a single GPU.

In essence, the Dell PowerEdge XE8640 is a top-tier server for organizations pushing the boundaries of AI, HPC, and data science, requiring extreme computational power and efficient data flow
