Intel Xeon Silver 4310 Server Configuration: A Technical Deep Dive
The Intel Xeon Scalable processor family, specifically the Silver tier, is designed to provide a robust foundation for mainstream enterprise workloads, offering a balance between core count, frequency, power efficiency, and cost-effectiveness. The Xeon Silver 4310, part of the 3rd Generation Intel Xeon Scalable processor family (codenamed Ice Lake-SP), represents a significant architectural enhancement over previous generations, particularly concerning PCIe connectivity and memory bandwidth.
1. Hardware Specifications
The core of this configuration is the Template:Intel Xeon Silver 4310 processor. Understanding its integrated architecture is crucial for optimizing the surrounding platform components (motherboard, memory, and I/O subsystem).
1.1. Central Processing Unit (CPU) Details

| Processor Family | Intel Xeon Scalable (3rd Gen, Ice Lake-SP) |
| Processor Number | 4310 |
| Core Count | 10 Cores |
| Thread Count | 20 Threads (via Hyper-Threading) |
| Base Clock Frequency | 2.10 GHz |
| Max Turbo Frequency (Single Core) | Up to 3.30 GHz |
| Intel Smart Cache (L3) | 18.75 MB |
| TDP (Thermal Design Power) | 120 W |
| Socket Compatibility | LGA 4189 (Socket E) |

| Instruction Set Architecture | x86-64, AVX-512 (VNNI, VBMI2, VPCLMULQDQ) |
| Integrated Graphics | None (Requires discrete GPU for display output) |
The inclusion of AVX-512 instruction sets, despite the Silver tier's lower clock speeds compared to Gold or Platinum, provides significant acceleration for specific vectorized workloads, such as certain HPC simulations or AI inference tasks. The LGA 4189 socket mandates specific motherboard designs optimized for the power delivery and thermal requirements of this processor generation.
1.2. Memory Subsystem Configuration
The 8-channel memory architecture provided by the Ice Lake-SP platform is a key performance differentiator. For the Xeon Silver 4310, the maximum supported speed is DDR4-2933 MT/s.
- **Channel Configuration:** 8 independent memory channels per socket.
- **Recommended DIMM Type:** DDR4 ECC Registered (RDIMM) or Load-Reduced (LRDIMM). ECC support is non-negotiable for enterprise reliability.
- **Optimal Population:** To achieve the full 2933 MT/s bandwidth, DIMMs must be populated symmetrically across all 8 channels. Using only 4 channels or populating specific slots incorrectly can downclock the memory speed, sometimes significantly (e.g., to 2666 MT/s or lower).
- **Maximum Capacity:** In a dual-socket configuration utilizing 64GB or 128GB DIMMs, system capacity can reach 4 TB or 8 TB, respectively, depending on the motherboard form factor (e.g., 16-DIMM per socket vs. 32-DIMM per socket boards).
1.3. Storage I/O Subsystem
The storage performance relies heavily on the platform's support for PCI Express 4.0. The 64 dedicated PCIe lanes per socket allow for extensive, high-bandwidth storage configuration.
- **PCIe Generation:** Gen 4.0 (Double the throughput of PCIe 3.0).
- **Lane Allocation:** A dual-socket system can allocate up to 128 PCIe lanes directly from the CPUs, enabling massive NVMe SSD arrays without relying on the slower Platform Controller Hub (PCH) lanes.
- **Recommended Storage Configuration:**
* **Boot/OS:** Dual M.2 NVMe drives configured in a RAID 1 array for redundancy, connected via dedicated PCIe add-in cards or motherboard slots. * **Data Tier 1 (High Performance):** U.2 or M.2 NVMe drives connected directly to the CPU lanes for maximum IOPS and throughput. A configuration supporting 16-24 NVMe drives is common. * **Data Tier 2 (Bulk Storage):** SAS/SATA SSDs or HDDs managed via a high-port-count RAID Controller (e.g., Broadcom MegaRAID series) connected via a PCIe 4.0 x16 slot.
1.4. Networking and Expansion
The required network interface card (NIC) speed depends entirely on the workload.
- **Standard Deployment:** Dual 10GbE (SFP+ or Base-T) connections, often utilizing integrated platform controllers (e.g., Intel E810 series).
- **High-Throughput/Storage Networking:** Support for 25GbE or even 100GbE connections is easily accommodated by the abundant PCIe 4.0 lanes. A single 100GbE NIC requires PCIe 4.0 x16 bandwidth for full utilization.
1.5. System Form Factor and Power
The Silver 4310's 120W TDP necessitates robust, but manageable, power delivery.
- **Form Factor:** Typically deployed in 1U/2U rackmount chassis optimized for density, or 4U tower/pedestal servers.
- **Power Supply Units (PSUs):** Redundant, high-efficiency (Platinum or Titanium rated) PSUs are standard. A dual 1200W or 1600W PSU setup is usually sufficient for a fully loaded 2U system running dual 4310s with numerous NVMe drives. Power Efficiency Metrics must be considered for operational expenditure (OpEx).

- 2. Performance Characteristics
The Xeon Silver 4310 is characterized by its 10-core density combined with the architectural improvements of the Ice Lake generation, especially PCIe 4.0. Its performance profile is generally balanced, excelling in I/O-intensive tasks rather than raw, single-threaded computational bottlenecks.
2.1. Core Density vs. Frequency Trade-off
The 2.1 GHz base clock is relatively modest compared to the higher-tier Gold processors, which often boost higher. However, the 10-core count provides substantial throughput capacity for heavily threaded applications.
- **Single-Threaded Performance:** Decent, benefiting from architectural IPC gains over previous generations (Cascade Lake), but not the primary selling point. Applications heavily reliant on latency or single-thread speed (e.g., some legacy database engines or older virtualization hosts) might see better performance from a higher-clocked Silver or Gold CPU with fewer cores.
- **Multi-Threaded Throughput:** Excellent for its price point. A dual-socket 4310 system offers 20 physical cores / 40 threads, providing a strong foundation for virtualization density or parallel processing.
2.2. Memory Bandwidth Impact
The 8-channel DDR4-2933 interface provides approximately 186 GB/s of theoretical aggregate bandwidth per socket. In a dual-socket configuration, this results in nearly 372 GB/s of total memory bandwidth.
- **Impact on In-Memory Databases:** This substantial bandwidth is critical for workloads operating on large datasets that must reside in RAM, such as In-Memory Databases (e.g., SAP HANA running smaller-scale deployments or specialized analytic engines).
- **NUMA Considerations:** In dual-socket systems, careful application configuration is required to ensure processes primarily access local memory channels to avoid the latency penalty associated with accessing the Non-Uniform Memory Access (NUMA) interconnect (UPI link).
2.3. I/O Bottleneck Alleviation
The greatest performance advantage of Ice Lake-SP over older generations (like Skylake/Cascade Lake) is the move to PCIe 4.0.
- **Storage Performance:** A single PCIe 4.0 x16 slot provides ~32 GB/s of bidirectional throughput. This capacity is essential for maximizing the performance of modern NVMe drives, which can easily saturate PCIe 3.0 x8 links. This configuration effectively eliminates storage I/O as a primary bottleneck for most standard enterprise applications.
- **Accelerator Support:** The ample lanes allow for the integration of multiple high-speed peripherals, such as FPGA accelerators or multiple discrete GPUs (though the 4310 is not typically chosen for heavy GPU compute clusters).
2.4. Benchmark Context (Illustrative)
While specific benchmark results vary widely based on system tuning (BIOS settings, memory population, OS scheduler), the 4310 generally lands in the following performance bracket relative to its predecessor (Xeon Silver 4210) and contemporary alternatives:
| Configuration | Core/Thread Count | Approx. SPECrate 2017_int (Normalized Base) | Primary Advantage |
|---|---|---|---|
| Xeon Silver 4210 (Cascade Lake) | 10C/20T | 100% | Lower initial investment (older platform) |
| Xeon Silver 4310 (Ice Lake) | 10C/20T | ~115% - 125% | IPC uplift, PCIe 4.0, 8-channel memory |
| Xeon Gold 6330 (Ice Lake) | 28C/56T | ~250% | Higher core density, higher frequency |
- Note: The performance uplift is primarily driven by the architectural improvements (IPC and PCIe Gen 4) rather than raw frequency scaling.*

- 3. Recommended Use Cases
The Intel Xeon Silver 4310 server configuration is optimally suited for environments requiring high I/O capacity, standardized enterprise resiliency, and predictable throughput at a controlled Total Cost of Ownership (TCO).
3.1. Virtualization Hosts (VM Density)
This configuration provides an excellent platform for hosting Virtual Machines (VMs) where the workload mix is heterogeneous and requires high I/O access.
- **VDI Infrastructure:** Serving as a host cluster for mid-sized Virtual Desktop Infrastructure (VDI) deployments. The 20 threads provide sufficient scheduling capacity, and the high memory bandwidth supports numerous user profiles actively swapping data.
- **General Purpose Virtualization:** Hosting standard enterprise workloads (e.g., Active Directory, DNS, smaller application servers) where 10 cores per physical server offer a good density multiplier without incurring the cost premium of the Gold or Platinum tiers.
3.2. Storage Servers and Hyper-Converged Infrastructure (HCI)
The native support for 64 PCIe 4.0 lanes per socket makes the 4310 a compelling choice for software-defined storage (SDS) solutions.
- **NVMe Over Fabric (NVMe-oF) Targets:** Ideal for building high-speed storage nodes where the primary bottleneck is moving data over the network or between storage devices. The 4310 can feed multiple 100GbE NICs and dozens of NVMe drives simultaneously without CPU starvation.
- **HCI Nodes (e.g., VMware vSAN, Ceph):** In HCI deployments, storage performance is paramount. The 4310 ensures that the storage controller software has sufficient bandwidth for both local drive access and inter-node replication traffic.
3.3. Web Hosting and Application Servers
For environments hosting high-traffic web services or running multi-threaded application servers (e.g., Java application servers, small-to-medium SQL databases).
- The combination of 20 threads and fast memory access allows for efficient handling of many concurrent user sessions.
- The 120W TDP profile contributes positively to data center power utilization effectiveness (PUE) when deployed at scale compared to higher-TDP parts.
3.4. Enterprise Edge/Branch Office Deployments
In geographically distributed data centers or secure branches, the Silver series often hits the required reliability standard (ECC memory, RAS features) while maintaining a lower initial capital expenditure (CapEx). The 1U/2U form factors are often preferred in these space-constrained environments.

- 4. Comparison with Similar Configurations
Choosing the right processor tier involves balancing performance needs against budget constraints. The 4310 is positioned against its direct predecessor (4210) and the next tier up (Gold 6330).
4.1. Comparison Table: Silver 4310 vs. Alternatives
This table highlights the critical decision points when selecting between these three configurations.
| Feature | Xeon Silver 4310 | Xeon Silver 4314 (Higher Silver Tier Example) | Xeon Gold 6330 (Entry Gold Tier Example) |
|---|---|---|---|
| Core Count | 10 | 16 | 28 |
| Base Frequency | 2.1 GHz | 2.4 GHz | 2.1 GHz |
| Max Turbo Frequency | 3.3 GHz | 3.7 GHz | 3.7 GHz |
| L3 Cache | 18.75 MB | 30 MB | 77 MB |
| Max Memory Speed | DDR4-2933 | DDR4-3200 | DDR4-3200 |
| TDP | 120 W | 150 W | 205 W |
| PCIe 4.0 Lanes | 64 per socket | 64 per socket | 80 per socket (Note: 4310/4314 often share 64) |
| Typical Use Case | I/O-heavy, density focus, cost-sensitive | Balanced density and throughput | High-performance virtualization, data analytics |
- Analysis:*
1. **Vs. Silver 4210 (Previous Gen):** The 4310 is almost always the superior choice due to the generational leap to PCIe 4.0 and the IPC improvements, even if the core count remains the same. The memory speed increase (2933 vs 2666) is also significant. 2. **Vs. Silver 4314:** If the workload requires more cores (16 vs 10) and slightly faster memory (3200 vs 2933) but must remain strictly within the Silver budget constraints, the 4314 provides a worthwhile bump in throughput for a small TDP increase. 3. **Vs. Gold 6330:** The Gold tier offers nearly double the core count (28 vs 10) and significantly more cache. This is necessary for workloads that are CPU-bound or require higher overall system throughput, outweighing the increased power draw and cost.
4.2. Licensing Implications
In many enterprise software environments (e.g., Microsoft SQL Server, Oracle Database), licensing is often based on the number of physical or logical cores.
- The 4310, with 20 threads, keeps the licensing footprint low, making it financially attractive for running licensed software where core count directly impacts CapEx.
- Deploying a 28-core Gold CPU can immediately double or triple the software licensing costs for the same physical footprint, often making the Silver tier the only viable option for budget-constrained licensed applications.

- 5. Maintenance Considerations
Deploying Xeon Silver 4310 systems requires adherence to specific maintenance protocols related to thermal management, power quality, and firmware integrity.
5.1. Thermal Management and Cooling
Although the 120W TDP is moderate, high-density deployments (especially dual-socket 1U servers) require diligent cooling practices.
- **Airflow Requirements:** Server chassis must adhere strictly to the manufacturer’s specified airflow patterns (front-to-back or side-to-side). Insufficient cooling in high-density racks leads to thermal throttling, where the CPU clocks down from the 2.1 GHz base frequency to maintain safe operating temperatures, severely impacting performance consistency.
- **Heatsinks:** Use only heatsinks certified for the LGA 4189 socket. Improper installation or use of non-specific heatsinks can lead to immediate thermal shutdown or long-term socket degradation.
- **Ambient Temperature:** Maintain data center ambient temperatures within the specification range (typically 18°C to 25°C) to ensure the processors can maintain peak turbo frequencies under load.
5.2. Power Delivery and Redundancy
The 120W TDP per CPU, combined with memory and storage power draw, necessitates high-quality PSUs.
- **PSU Selection:** Always deploy dual, redundant PSUs (1+1 configuration). For a typical dual-socket 4310 system with 12-16 DIMMs and 8-12 NVMe drives, 1200W Platinum-rated PSUs provide ample headroom for power spikes and high efficiency under typical load profiles.
- **Firmware Updates:** Regular updates to the BIOS/UEFI firmware and the Baseboard Management Controller (BMC) firmware are essential. These updates often contain critical microcode patches that address security vulnerabilities (e.g., Spectre/Meltdown variants) or improve power management logic specific to the Ice Lake microarchitecture.
5.3. Memory Population and Reliability
The 8-channel memory structure demands careful population to maintain performance and reliability.
- **Symmetry:** Always populate memory channels symmetrically across all sockets. For instance, if slot A1 is populated, the corresponding slot on the second CPU (B1) must also be populated, and similarly for all other channels. Failure to do this will result in lower memory frequency due to the controller defaulting to a lower operating mode.
- **ECC Validation:** Regular memory testing using tools like MemTest86 or built-in BMC diagnostics is necessary to ensure the integrity of the ECC memory modules, which are the primary defense against soft errors in enterprise environments.
5.4. Operating System and Driver Support
The 3rd Generation Xeon Scalable processors rely on modern operating systems for optimal utilization of features like AVX-512 and PCIe 4.0.
- **OS Compatibility:** Ensure the operating system kernel (e.g., Linux kernel 5.x+, Windows Server 2019/2022) includes the necessary drivers and scheduler optimizations for Ice Lake. Older OS versions may not recognize or correctly utilize the advanced features, leading to suboptimal performance or stability issues.
- **Storage Drivers:** Specific vendor drivers for NVMe controllers and RAID cards must be updated to ensure they correctly expose the PCIe 4.0 bandwidth capabilities to the operating system.
