1. Hardware Specifications

This document details the CPU compatibility and overall specifications for a high-performance, dual-socket server platform designed for demanding workloads such as virtualization, data analytics, and high-performance computing. The core of this system revolves around the Intel Xeon Scalable Gen 4 processor family.

1.1. CPU Details

The primary CPU component is the Intel Xeon Platinum 8480+, a 56-core, 112-thread processor with a base frequency of 2.0 GHz and a maximum Turbo Boost frequency of 3.8 GHz. This CPU utilizes the LGA 4677 socket. Key specifications are outlined below:

Specification Value
CPU Model Intel Xeon Platinum 8480+
Cores / Threads 56 / 112
Base Frequency 2.0 GHz
Max Turbo Frequency 3.8 GHz
Cache (L3) 105 MB
TDP (Thermal Design Power) 350W
Socket Type LGA 4677
Memory Support DDR5-4800 ECC Registered DIMMs
PCIe Support PCIe 5.0 & PCIe 4.0
UPI Link Speed 11.2 GT/s (UPI links are critical for inter-processor communication – see UPI Link Architecture)

We are employing *two* of these CPUs in a dual-socket configuration. This provides a total of 112 cores and 224 threads. CPU selection considered alternatives like the Intel Xeon Gold 6448R and the AMD EPYC 9654 (see section 4 for a detailed comparison). The Platinum 8480+ was chosen for its superior core count and performance in heavily threaded applications.

1.2. Motherboard

The motherboard is a Supermicro X13DEI-N6, specifically designed for dual Intel Xeon Scalable Gen 4 processors. It supports the LGA 4677 socket and features the Intel C621A chipset. Important motherboard features include:

  • 16 x DDR5 DIMM slots supporting up to 8TB of RAM
  • 6 x PCIe 5.0 x16 slots
  • 2 x PCIe 4.0 x16 slots
  • Dual 10 Gigabit Ethernet ports ([Ethernet Networking]])
  • Integrated IPMI 2.0 remote management interface ([Remote Server Management]])
  • Multiple M.2 slots for NVMe SSDs ([NVMe Storage Technology]])

1.3. Memory

The system is equipped with 16 x 512GB DDR5-4800 ECC Registered DIMMs, totaling 8TB of RAM. ECC Registered memory is crucial for server stability and data integrity. Memory speed of 4800 MHz is the optimal balance between performance and cost for this platform. Memory timings are CL40. The motherboard supports memory mirroring and advanced error correction features – see Memory Error Handling.

1.4. Storage

Storage consists of:

  • 2 x 3.2TB NVMe PCIe 4.0 SSDs (boot drives) in RAID 1 configuration ([RAID Configuration]])
  • 8 x 16TB SAS 12Gbps HDDs in RAID 6 configuration for bulk storage ([SAS Storage Technology]])
  • 1 x U.2 NVMe SSD (15.36TB) for high-speed caching.

1.5. Power Supply

Dual redundant 1600W 80+ Titanium power supplies. Redundancy is essential for high availability. Power supplies are hot-swappable. ([Power Supply Redundancy]])

1.6. Cooling

High-performance air cooling solution with dedicated CPU heatsinks and fans. Liquid cooling was considered, but the increased complexity and maintenance outweighed the marginal performance gains. Server room ambient temperature is maintained at 22°C. See Server Cooling Systems for detailed information.

1.7. Network Interface

Dual 10 Gigabit Ethernet ports integrated into the motherboard. Optional 100 Gigabit Ethernet card available for future upgrades. ([Network Connectivity]])

4. Comparison with Similar Configurations

Here’s a comparison of this configuration with alternatives:

Configuration CPU RAM Storage Price (Approx.) Strengths Weaknesses
**Our Configuration** Dual Intel Xeon Platinum 8480+ 8TB DDR5-4800 ECC Registered 2x 3.2TB NVMe (RAID 1) + 8x 16TB SAS (RAID 6) + 1x 15.36TB U.2 NVMe $35,000 Highest core count, excellent performance, large RAM capacity, redundant components. High cost.
**Configuration 1** Dual Intel Xeon Gold 6448R 4TB DDR5-4800 ECC Registered 2x 3.2TB NVMe (RAID 1) + 6x 16TB SAS (RAID 6) $25,000 Lower cost, still good performance. Lower core count, less RAM.
**Configuration 2** Dual AMD EPYC 9654 8TB DDR5-4800 ECC Registered 2x 3.2TB NVMe (RAID 1) + 8x 16TB SAS (RAID 6) + 1x 15.36TB U.2 NVMe $30,000 Competitive performance, strong price/performance ratio. Potentially more complex software licensing for some applications, slightly lower single-core performance. ([AMD EPYC Architecture])
**Configuration 3** Single Intel Xeon Platinum 8480+ 4TB DDR5-4800 ECC Registered 2x 3.2TB NVMe (RAID 1) + 4x 16TB SAS (RAID 6) $20,000 Lower cost, simpler configuration. Reduced core count and overall performance.

The AMD EPYC 9654 offers a strong price-to-performance ratio, but the Intel Xeon Platinum 8480+ generally outperforms it in heavily threaded workloads and often has better software compatibility within established enterprise environments. The Gold 6448R configuration is a more cost-effective option when extreme performance is not required.
