This document provides a comprehensive technical specification and operational guide for the standardized IT Infrastructure server configuration, designed for high-density, scalable enterprise workloads. This configuration prioritizes a balance between computational throughput, I/O latency, and energy efficiency, making it suitable for a wide array of mission-critical applications.
1. Hardware Specifications
The IT Infrastructure configuration is built upon the latest generation of dual-socket server architecture, optimized for virtualization density and database operations. All components adhere to stringent enterprise-grade reliability standards (e.g., MTBF > 150,000 hours).
1.1. System Baseboard and Chassis
The foundation of this configuration is a 2U rack-mountable chassis supporting dual-socket motherboards compliant with the latest Intel Xeon Scalable Processor generation standards (e.g., Sapphire Rapids or equivalent AMD EPYC Milan/Genoa).

| Feature | Specification |
|---|---|
| Memory Technology | DDR5 ECC RDIMM |
| Total Installed Capacity | 1024 GB (1 TB) |
| Module Size | 8 x 128 GB DIMMs |
| Configuration | Populating 8 channels on each of the 2 CPUs (16 DIMM slots total, 50% utilization for balanced loading) |
| Memory Speed | 4800 MT/s (JEDEC Standard) |
| Memory Channels Utilized | 16 Channels (8 per socket) |
| Memory Type Classification | Tier 1 Enterprise Grade (Verified against Server Memory Standards) |
Note: While the platform supports up to 32 DIMMs in some configurations, using 16 DIMMs (8 per socket) ensures optimal access timing and adheres to the 8-channel population requirement for maximum bandwidth utilization at the specified speed.
1.4. Storage Subsystem
The storage architecture is designed for high Input/Output Operations Per Second (IOPS) and low latency, utilizing a hybrid NVMe/SAS approach for the operating system, boot volumes, and primary data tiers.
1.4.1. Boot and OS Storage (Tier 0)
Two mirrored M.2 NVMe SSDs are dedicated for the hypervisor boot image and critical system files.
1.4.2. Primary Data Storage (Tier 1)
The main storage array leverages ultra-high-speed PCIe Gen 4/5 NVMe drives organized in a high-redundancy RAID configuration (RAID 10 equivalent via hardware controller).
| Component | Specification |
|---|---|
| Boot Drives (x2) | 960 GB M.2 NVMe (SATA Interface compatible, configured for RAID 1) |
| Primary Data Drives (x12) | 3.84 TB U.2 NVMe SSD (Enterprise Endurance: 3 DWPD) |
| Total Usable Primary Capacity | Approximately 18.4 TB (Post-RAID 10 overhead for 12 drives) |

| PCIe Interface for Controller | PCIe 5.0 x16 |
| RAID Configuration | RAID 60 (for maximum resilience on the NVMe array) |
The selection of RAID 60 on the NVMe array provides excellent read/write performance while offering protection against two simultaneous drive failures within the array groups. RAID Level Comparison provides further context on this choice.
1.5. Networking Components
High-throughput, low-latency networking is essential for modern cluster communication and storage access (e.g., NVMe-oF).
| Interface Type | Quantity | Speed | Purpose |
|---|---|---|---|
| LOM (Base) | 2 | 25GbE (SFP28) | Primary Data Plane / Cluster Interconnect |
| Expansion Card (Dedicated) | 1 | 100GbE (QSFP28) | High-Speed Storage Fabric (e.g., RoCEv2) or Uplink |
| Management Port | 1 | 1GbE (RJ45) | Dedicated OOB Management (IPMI/BMC) |
The 100GbE card is typically configured as an active/standby pair or bonded for specific high-bandwidth applications like VMware vSAN or large-scale data migration tasks.
1.6. Power Supply Units (PSUs)
Redundancy and efficiency are paramount. The system uses dual hot-swappable PSUs rated for 80 PLUS Titanium efficiency.
| Feature | Specification |
|---|---|
| PSU Configuration | 2 x Redundant Hot-Swap Modules |
| PSU Rating (Per Unit) | 2000W |
| Efficiency Rating | 80 PLUS Titanium (>= 94% efficiency at 50% load) |
| Input Voltage Support | 100-240V AC (Auto-Sensing) |
| Power Distribution | N+1 Redundancy |
This configuration ensures that the system can handle peak transient loads from all components (CPUs under maximum turbo, all NVMe drives active) while maintaining high efficiency during typical operational states. Power Density in Data Centers offers context on rack-level power planning.
2. Performance Characteristics
The IT Infrastructure configuration is benchmarked against standard enterprise workloads to validate its suitability for demanding environments. Performance metrics focus on virtualization density, transactional throughput, and I/O latency.
2.1. Virtualization Density Benchmarks
The 64-core/128-thread configuration, coupled with 1TB of high-speed DDR5 RAM, allows for significant VM consolidation ratios.
VM Density Testing (Standardized 4 vCPU / 16 GB RAM Guest Profile):
The testing utilized the SPECvirt_2017 benchmark suite, simulating typical enterprise workloads (Web Server, Database, Application Server).
| Metric | Result | Target Threshold |
|---|---|---|
| Total VM Capacity (Sustained) | 78 VMs | >= 70 VMs |
| Average CPU Ready Time (ms) | 1.2 ms | < 2.0 ms |
| Memory Utilization Ceiling | 85% | < 90% |
The low CPU Ready Time confirms that the high core count and fast memory subsystem effectively manage scheduling contention, a critical factor in high-density environments.
2.2. Database Transactional Performance (OLTP)
For Online Transaction Processing (OLTP) workloads, the primary bottlenecks are usually memory latency and storage IOPS/latency. The use of high-speed NVMe in RAID 60 significantly mitigates storage bottlenecks.
TPC-C Benchmark Simulation (Simplified):
Testing focused on the transaction throughput capability of a standardized MySQL/PostgreSQL instance running on the server.
| Metric | Result (Transactions Per Minute - tpmC) | Comparison Baseline (Previous Gen Server) |
|---|---|---|
| Peak tpmC | 450,000 | +35% Improvement |
| Average Latency (Commit Time) | 850 microseconds (µs) | -20% Latency Reduction |
The latency reduction is directly attributable to the PCIe Gen 5 connectivity for the storage subsystem and the faster memory access times afforded by DDR5. Detailed analysis is available in the Database Performance Tuning Guide.
2.3. I/O Throughput and Latency
Storage performance is quantified using FIO (Flexible I/O Tester) targeting 128KB sequential reads/writes and 4KB random I/O.
| Operation Type | Throughput (GB/s) | IOPS (4K Random Read) |
|---|---|---|
| Sequential Read (128K) | 28.5 GB/s | N/A |
| Sequential Write (128K) | 22.1 GB/s | N/A |
| Random Read (4K) | N/A | 1.8 Million IOPS |
| Random Write (4K) | N/A | 1.5 Million IOPS |
These figures demonstrate that the storage subsystem is capable of sustaining high throughput required for large data transfers while maintaining the extremely high IOPS necessary for transactional databases.
2.4. Power Consumption Profile
Understanding the power envelope is vital for data center capacity planning. Measurements were taken at the PSU input under varying load conditions.
| Load State | Measured Power Draw (W) | Estimated Utilization |
|---|---|---|
| Idle (OS/Hypervisor Only) | 285 W | < 5% CPU Load |
| 50% Utilization (Typical VM Load) | 710 W | ~40% CPU Load |
| Peak Load (Stress Testing) | 1420 W | 100% CPU Load, Max I/O |
The Titanium-rated PSUs ensure that even at peak load, the power conversion loss remains minimal, contributing to a lower Power Usage Effectiveness (PUE) for the rack.
3. Recommended Use Cases
The IT Infrastructure configuration is a versatile platform, but its strengths lie in environments requiring balanced compute, high memory bandwidth, and low-latency storage access.
3.1. Enterprise Virtualization Hosts
This configuration is ideally suited as the backbone for a virtualized infrastructure (e.g., running VMware vSphere or Microsoft Hyper-V).
- **Density:** The 128 logical processors and 1TB of RAM support high consolidation ratios for general-purpose server workloads (e.g., file servers, application servers, web front-ends).
- **Scalability:** The high number of PCIe Gen 5 lanes allows for easy expansion with specialized accelerators (GPUs or high-speed InfiniBand adapters) without impacting base system performance.
3.2. High-Performance Database Servers
For mission-critical OLTP and moderate-sized OLAP databases where latency directly impacts business operations, this server excels.
- **In-Memory Databases:** The large, fast memory pool (1TB DDR5) supports large buffer caches critical for systems like SAP HANA or highly optimized SQL Server instances.
- **Transactional Workloads:** The combination of high core frequency and ultra-low-latency NVMe storage (sub-millisecond access) ensures rapid commit times.
3.3. Private Cloud Infrastructure Nodes
As a core component of a private cloud (e.g., running OpenStack or Kubernetes), this hardware provides the necessary resource density and fast interconnects for container orchestration and software-defined storage networking. The 25GbE base networking meets the baseline requirements for modern container ingress/egress.
3.4. Big Data Processing (Edge/Mid-Tier)
While not optimized for pure map-reduce (which often favors higher core counts over clock speed), this configuration is excellent for mid-tier data processing services, such as Spark driver nodes or Kafka brokers, where fast memory access and quick task scheduling are necessary.
4. Comparison with Similar Configurations
To contextualize the IT Infrastructure configuration (designated as **Config-A**), we compare it against two common alternatives: a high-density storage server (**Config-S**) and a pure compute-optimized server (**Config-C**).
4.1. Configuration Profiles Overview
| Feature | Config-A (IT Infrastructure) | Config-S (Storage Optimized) | Config-C (Compute Optimized) |
|---|---|---|---|
| CPU Configuration | 2 x 32-Core (Balanced) | 2 x 48-Core (Lower Clock) | 2 x 64-Core (Highest Core Count) |
| Total RAM | 1 TB DDR5 | 512 GB DDR5 | 2 TB DDR5 |
| Primary Storage (NVMe) | 12 x 3.84 TB (RAID 60) | 24 x 7.68 TB (RAID 6) | 4 x 1.92 TB (RAID 1) |
| Base Networking | 25GbE LOM | 10GbE LOM | 100GbE LOM (Dual Port) |
| Primary Focus | Balanced I/O & Compute | Maximum Raw Capacity & Throughput | Maximum Thread Count & Memory Bandwidth |
4.2. Performance Trade-Off Analysis
The comparison highlights the deliberate trade-offs made in Config-A: sacrificing some maximum storage capacity (Config-S) and some maximum thread count (Config-C) to achieve superior latency characteristics and a higher effective clock speed for single-threaded or latency-sensitive processes.
Latency Comparison (4K Random Read):
| Configuration | Average Latency | Best Case Latency |
|---|---|---|
| Config-A (Balanced NVMe) | 115 µs | 78 µs |
| Config-S (High-Density NVMe) | 180 µs | 130 µs |
| Config-C (Minimal NVMe) | 95 µs | 65 µs |
Config-C achieves slightly better latency due to the smaller, less complex RAID array, but Config-A provides significantly better usable capacity at an acceptable latency penalty. Config-S suffers latency due to the higher number of drives managed by the controller, impacting queue depth performance.
4.3. Cost-Efficiency Index (CEI)
Cost-Efficiency Index (CEI) is calculated based on the ratio of sustained TPC-C score to the fully loaded system cost (Hardware + Power).
| **Configuration** | **CEI Score (Relative)** | **Best Application** | | :--- | :--- | :--- | | Config-A | 1.0 (Baseline) | General Enterprise Workloads | | Config-S | 0.75 | Scale-out Storage/Backup Targets | | Config-C | 1.15 | HPC/Large-Scale In-Memory Analytics |
Config-A represents the most prudent choice for heterogeneous environments where workloads fluctuate, as detailed in the Data Center Workload Profiling document.
5. Maintenance Considerations
Proper lifecycle management, power planning, and thermal management are non-negotiable for maintaining the reliability targets of the IT Infrastructure configuration.
5.1. Thermal Management and Cooling Requirements
Given the 270W TDP CPUs and high-density NVMe drives, thermal dissipation is a critical design factor.
- **Airflow Requirements:** The 2U chassis requires a minimum sustained front-to-back airflow velocity of 200 Linear Feet Per Minute (LFM) at the server intake.
- **Maximum Ambient Temperature:** The system is rated for operation up to 35°C (95°F) inlet temperature, though sustained operation is recommended below 27°C (80.6°F) to maximize component lifespan.
- **Fan Configuration:** The system utilizes high-static-pressure redundant fans. Any fan failure triggers an immediate P1 alert via Redfish API and requires replacement within 24 hours to maintain the N+1 redundancy margin.
5.2. Power Management and Redundancy
The dual 2000W Titanium PSUs provide significant headroom, but capacity planning must account for peak draw.
- **Rack Power Density:** A full rack populated exclusively with this configuration (typically 42 units) requires approximately 30 kW of continuous power capacity, accounting for the 1420W peak draw per server plus overhead.
- **Firmware Updates:** Regular updates to the BIOS/UEFI Firmware and the BMC are mandatory to ensure correct power capping and thermal throttling algorithms are active, particularly after introducing new OS kernel versions or hypervisors.
5.3. Storage Controller Maintenance
The hardware RAID controller managing the NVMe array requires specific maintenance protocols:
1. **Cache Battery Backup Unit (BBU/Supercapacitor):** The health of the BBU must be checked quarterly. If the BBU fails a self-test, write-back caching is automatically disabled by the controller firmware, potentially crippling write performance until replacement. 2. **Drive Firmware Synchronization:** Due to the high drive count (12 in the primary array), ensuring all NVMe drive firmware versions are synchronized across the array is essential to prevent inconsistent wear leveling or unexpected drive failures. Use the vendor-specific Storage Management Tool for batch updates. 3. **Data Scrubbing:** A full array data scrub cycle (parity check) must be scheduled bi-weekly to proactively detect and correct silent data corruption (bit rot). This process typically causes a 15-20% reduction in write performance during execution.
5.4. Remote Management and Monitoring
The BMC interface (IPMI/Redfish) is the primary tool for remote maintenance. Key metrics to monitor continuously include:
- **CPU Temperature (Tdie):** Alert if sustained above 95°C.
- **Memory Voltage Stability:** Monitor VDDQ and VPP rail stability.
- **NIC Link Negotiation:** Verify that 25GbE links maintain full duplex connectivity during cluster maintenance windows.
Implementing robust SNMP Monitoring integration with the central IT monitoring suite is required for proactive alerting based on these thresholds.
