| Memory Channels Utilized | 8 Channels per CPU (16 Total) |
| Configuration Strategy | Balanced interleaving across all available channels for maximum bandwidth. |
For mission-critical applications, Error-Correcting Code (ECC) is mandatory to ensure data integrity, a standard feature on all server-grade DDR5 RDIMMs.
1.3. Storage Subsystem
The storage architecture focuses on high-speed, low-latency NVMe devices, utilizing a tiered approach for the operating system, application binaries, and high-demand data storage. The system utilizes a dedicated NVMe Host Controller Interface (HCI) via the motherboard's integrated PCIe root complex or a dedicated Add-in-Card (AIC) controller for maximum lane allocation.
1.3.1. Boot/OS Drive
- **Type:** 2x 960GB M.2 NVMe SSD (Enterprise Grade)
- **Configuration:** Mirrored RAID 1 (Software or Hardware RAID, depending on licensing constraints)
- **Purpose:** Windows Server 2022 installation and core binaries.
1.3.2. Primary Data/Application Storage
This tier utilizes high-endurance, high-IOPS PCIe Gen 4/5 NVMe drives connected via a dedicated PCIe Switch or directly to the CPU root complexes for minimal latency.

The use of Remote Direct Memory Access (RDMA) capabilities via RoCE is crucial for minimizing CPU overhead during high-volume intra-cluster communication or Storage Migration operations.
1.5. Expansion Slots and Power
The chassis must accommodate the high power draw and physical space requirements of the components.
| Component | Requirement |
|---|---|
| PCIe Slots | Minimum 6 x PCIe Gen 5 x16 slots (4 occupied by primary storage/NICs) |
| Power Supply Units (PSUs) | 2x 2200W Redundant (N+1 configuration) |
| Efficiency Rating | 80 PLUS Platinum or Titanium |
| Power Connectors | Required 8-pin EPS connectors for dual CPUs and supplemental PCIe power for high-draw cards. |
The PSU redundancy is critical, ensuring that power loss to a single unit does not interrupt service, a key aspect of High Availability (HA) design.
2. Performance Characteristics
The WSC-HP-2024 configuration is benchmarked against standard enterprise metrics to validate its suitability for high-demand roles. All testing uses Windows Server 2022 Datacenter Edition with all required performance tuning applied (e.g., memory interleaving optimization, large page support enabled, and specific driver tuning).
2.1. CPU Performance Metrics
The 128-core configuration provides exceptional parallel processing capability.
| Benchmark Tool | Metric | Result (WSC-HP-2024) |
|---|---|---|
| SPECrate 2017 Integer | Global Rate Score | ~1150 |
| SPECpower_ss_i2008 | Efficiency (Score/Watt) | 48.5 |
| Linpack (Floating Point Ops) | TFLOPS (Peak Theoretical) | ~11.5 TFLOPS (Double Precision) |
The high core count allows for substantial VM density while maintaining performance isolation between tenants.
2.2. Memory Bandwidth and Latency
Achieving maximum theoretical memory bandwidth requires careful population of the DDR5 slots.

|---|---|---|
| Aggregate Read Bandwidth | 850 GB/s (Sustained) | Measured using AIDA64 Extreme Memory Benchmark across all 16 channels. |
| Aggregate Write Bandwidth | 780 GB/s (Sustained) | Write performance slightly lower due to memory controller overhead. |
| Memory Latency (First Access) | 65 ns | Measured between NUMA nodes (inter-socket communication latency is ~110 ns). |
The utilization of Transparent Huge Pages (THP) via Windows Server Large Pages configuration is essential to leverage this bandwidth effectively, reducing Translation Lookaside Buffer (TLB) misses.
2.3. Storage Input/Output Operations Per Second (IOPS)
The NVMe RAID 10 array is the primary bottleneck constraint in I/O-intensive sequential workloads, but its random IOPS performance is industry-leading.
| Workload Type | Measured IOPS (Aggregate) | Latency (P99) |
|---|---|---|
| Random Read (Mixed) | 3,200,000 IOPS | < 150 microseconds |
| Random Write (Mixed) | 2,850,000 IOPS | < 180 microseconds |
| Sequential Read (128K Block) | 18 GB/s | N/A |
These performance figures confirm the system's readiness for high-churn database workloads, such as Microsoft SQL Server OLTP environments.
2.4. Network Throughput
Testing involved using iPerf3 across the dual 100GbE interfaces, configured in a Switch Independent Teaming Mode (SIT) or using SMB Multichannel when communicating with other compatible servers.
- **Single Stream Throughput:** 98 Gbps (TCP/IP, single flow)
- **Aggregate Throughput (4 Streams):** 195 Gbps (Utilizing both 100GbE ports)
- **RDMA Latency (Ping):** < 2.5 microseconds (between two WSC-HP-2024 nodes)
The low RDMA latency is critical for minimizing synchronization overhead in clustered file systems or distributed in-memory caches.
3. Recommended Use Cases
The WSC-HP-2024 configuration is explicitly designed to handle workloads that are currently constrained by CPU core count, memory capacity, or I/O bandwidth on legacy infrastructure.
3.1. Virtualization Host (Hyper-V Cluster Node)
With 128 physical cores and 2TB of high-speed RAM, this configuration is ideal for dense hosting of Microsoft Hyper-V workloads.
- **Density Target:** Capable of reliably hosting 150-200 standard Windows Server VMs or 40-50 high-performance Linux/Windows containers, depending on resource allocation policies.
- **Key Benefit:** The high core count minimizes core oversubscription ratios, ensuring predictable performance for critical guest operating systems. The 100GbE networking supports high-speed Live Migration traffic without impacting application performance.
3.2. High-Transaction Database Server
This configuration is optimized for transactional database systems (OLTP) requiring rapid access to large datasets residing in memory or on ultra-fast local storage.
- **Database Platforms:** SQL Server Enterprise, Oracle Database Enterprise Edition.
- **Optimization Focus:** The 2TB RAM pool allows for massive caching of database indexes and working sets, reducing reliance on storage I/O. The NVMe array handles transaction log writes with minimal latency impact.
- **Requirement:** Requires careful configuration of Database Memory Allocation to utilize Windows Large Pages effectively.
3.3. High-Performance Computing (HPC) and Analytics

- **Scalability Buffer:** Allows for application growth over 3-5 years before requiring hardware refresh, based on current enterprise growth projections.
4. Comparison with Similar Configurations
To place the WSC-HP-2024 configuration in context, we compare it against two common alternatives: the "Density Optimized" configuration (WSC-DO-2024) and the "Cost Optimized" configuration (WSC-CO-2024).
4.1. Configuration Overview Table
| Feature | WSC-HP-2024 (High Performance) | WSC-DO-2024 (Density Optimized) | WSC-CO-2024 (Cost Optimized) |
|---|---|---|---|
| CPU Configuration | 2P 64-Core (2.4 GHz+) | 2P 96-Core (Lower Clock, Higher Density) | 2P 32-Core (Mid-Range Frequency) |
| Total RAM | 2048 GB DDR5-5600 | 4096 GB DDR5-4800 (Lower Speed) | 512 GB DDR5-4800 |
| Primary Storage | 8x 7.68TB NVMe (RAID 10) | 12x 3.84TB SATA SSD (RAID 5) | 4x 1.92TB SATA SSD (RAID 1) |
| Network Interface | Dual 100GbE w/ RoCE | Dual 25GbE | Dual 10GbE |
| Target Workload | Database, HPC, High-Density Virtualization | Hyper-Converged Infrastructure (HCI), Scale-Out Storage | Domain Controller, File Server, Light Virtualization |
| Relative Cost Index (1.0 = WSC-CO) | 3.5x | 2.8x | 1.0x |
4.2. Performance Trade-offs Analysis
The primary trade-off in the WSC-HP-2024 is cost versus raw speed. While the Density Optimized configuration offers more total RAM (4TB vs 2TB) and a higher physical core count (192 vs 128), the performance of the HP configuration excels due to:
1. **Faster Clock Speed:** Higher base and turbo frequencies benefit latency-sensitive, vertically scaling applications better than raw core count in some legacy applications. 2. **Superior I/O Path:** The dedicated NVMe RAID 10 array in the HP configuration provides significantly lower IOPS latency (sub-200µs vs. typical 1-3ms for SATA SSD RAID 5). 3. **Networking:** The 100GbE infrastructure supports faster data movement required for synchronous clustering and rapid data synchronization, whereas the DO configuration is often limited by 25GbE interconnects.
The Cost Optimized configuration serves purely as a baseline, unsuitable for the high-demand scenarios targeted by the WSC-HP-2024. Users considering the DO configuration must accept reduced single-threaded performance and significantly slower storage subsystems.
5. Maintenance Considerations
Deploying a high-density, high-power server configuration like the WSC-HP-2024 introduces specific requirements concerning power delivery, cooling infrastructure, and operational procedures. Failure to adhere to these guidelines will result in thermal throttling, reduced component lifespan, and potential service disruption.
5.1. Thermal Management and Cooling
The combined TDP of the dual CPUs (700W) plus the power draw of 32 DIMMs and high-speed NVMe drives pushes the system well into the high-density thermal category.
- **Rack Density:** This server occupies 2U or 3U space, demanding placement within racks equipped with high-capacity cooling units.
- **Airflow Requirements:** Minimum sustained airflow velocity of 200 Linear Feet per Minute (LFM) across the server face is required. The cooling infrastructure must support Hot Aisle/Cold Aisle Containment best practices.
- **Ambient Temperature:** The server must operate within the ASHRAE TC 9.9 Class A1 or A2 envelope. Maximum allowable ambient intake temperature should not exceed 25°C (77°F) under full sustained load to prevent CPU throttling below the specified 2.4 GHz base clock.
5.2. Power Delivery and Redundancy
The system requires significant, clean power delivery.
- **Total Power Draw (Peak):** Estimated at 1800W – 2000W under maximum simulated load (CPU stress testing + 100GbE saturation).
- **UPS Sizing:** Uninterruptible Power Supply (UPS) systems must be sized to handle the peak load plus overhead for at least 15 minutes of runtime. For a rack containing four (4) WSC-HP-2024 units, a minimum 15 kVA UPS system is recommended.
- **Firmware Management:** Regular updates to the Baseboard Management Controller (BMC) firmware are critical. BMC firmware controls thermal fan curves and power capping mechanisms. Outdated firmware can lead to aggressive, unnecessary fan ramping or, conversely, insufficient cooling during transient load spikes.
5.3. Operating System Tuning and Monitoring
The performance benefits of this hardware configuration are only realized if the operating system is correctly tuned for 2P, high-memory environments.
- 5.3.1. Windows Server Tuning Checklist
1. **Power Plan:** Must be set to **High Performance** (or equivalent OEM optimized profile). The default Balanced plan can cause unnecessary clock speed oscillation. 2. **NUMA Awareness:** Ensure all high-I/O applications (databases, virtualization stacks) are configured to utilize NUMA-aware scheduling. Tools like `Get-NetAdapterStatistics` should be routinely checked to ensure traffic is balanced across both network adapters and their associated NUMA nodes. 3. **Storage Driver Optimization:** Utilize vendor-specific NVMe drivers (e.g., Microsoft StorNVMe or specific vendor drivers) that support the required Queue Depth (QD=256 or higher) for the U.2 drives. 4. **Large Pages:** Enable the "Lock pages in memory" user right for critical services (e.g., SQL Server) and ensure the OS is provisioned to use Windows Server Large Pages to minimize TLB misses.
- 5.3.2. Monitoring Prerequisites
Comprehensive monitoring is required to track component health and prevent thermal runaway.
- **Telemetry:** Implement monitoring for CPU temperature (TjMax threshold alerts), PSU voltage/amperage fluctuations, and memory error counters (ECC events).
- **Resource Saturation:** Track CPU utilization not just by percentage, but by **Ready Time**. High Ready Time indicates that the system is waiting on I/O or memory access, pointing toward the need for further storage or networking optimization, rather than just more cores.
5.4. Lifecycle Management and Component Replacement
Due to the high density of components, component failure handling requires specific procedures.
- **DIMM Replacement:** Replacing a DIMM requires careful adherence to the Memory Population Rules dictated by the motherboard vendor to maintain dual-channel/quad-channel balance across both CPUs. Improper seating can lead to immediate system instability or reduced memory speed.
- **NVMe Drive Swapping:** Hot-swapping U.2 drives is supported only if the backplane/carrier system supports PCIe hot-plug signaling and the RAID controller driver is configured for hot-add events. Otherwise, a controlled shutdown is mandatory before physical replacement to prevent data corruption on the active RAID array.
