| L3 Cache Total | 120 MB per socket (240 MB Aggregate) | 384 MB per socket (768 MB Aggregate) |
| PCIe Lanes Supported | 80 Lanes per socket (160 Total) | 128 Lanes per socket (256 Total) |
- Note: The selection between Option A and Option B must be driven by the primary workload requirements (see Section 3). Option B maximizes thread count but may slightly reduce sustained single-thread performance compared to Option A's higher base clock.*
1.2 Memory Subsystem
The TSC leverages DDR5 ECC Registered DIMMs (RDIMMs) to support high capacity and bandwidth. The platform supports 16 DIMM slots per socket (32 total slots).
| Parameter | Specification | Rationale |
|---|---|---|
| Memory Type | DDR5 ECC RDIMM | Error Correction and high-speed data transfer. |
| Maximum Speed Supported | 4800 MT/s (JEDEC standard load) | Dependent on CPU memory controller configuration and population density. |
| Total Slot Count | 32 (16 per CPU) | Maximizes memory adjacency for NUMA locality. |
| Minimum Configuration | 256 GB (8 x 32GB DIMMs, balanced across sockets) | Ensures proper NUMA topology recognition. |
| Recommended Configuration | 1024 GB (16 x 64GB DIMMs) | Optimal balance for high-density virtualization. |
| Maximum Capacity | 4 TB (32 x 128GB DIMMs) | Requires specific high-density DIMM support from the motherboard BIOS. |
| Memory Channel Architecture | 8 Channels per CPU | Critical for achieving maximum memory throughput. |
1.3 Storage Architecture
The storage subsystem is designed for high IOPS density, favoring NVMe over traditional SAS/SATA where possible, though backward compatibility is maintained for legacy RAID configurations.
The chassis provides 16 front-accessible SFF drive bays, configurable via a dedicated backplane supporting SAS/SATA or NVMe (U.2/E3.S).
| Bay Type | Quantity | Interface Support | Primary Controller |
|---|---|---|---|
| Front Bays (SFF) | 16 (Hot-Swap) | NVMe (PCIe Gen 5 x4) or SAS3/SATA 6Gbps | Dedicated Hardware RAID Controller (e.g., Broadcom Tri-Mode) |
| Internal Boot Drive(s) | 2 (Optional) | M.2 NVMe (PCIe Gen 4) | Onboard SATA/M.2 Host Controller |
| Maximum Theoretical Throughput (All NVMe) | ~ 60 GB/s (Read Aggregated) | Based on 16 drives utilizing PCIe Gen 5 x4 lanes. |
The primary storage controller must be a PCIe Gen 5 capable expansion card (x16 slot required) to avoid I/O bottlenecks imposed by the CPU/Chipset interface limitations. Refer to PCIe Lane Allocation documentation for specific slot assignments.
1.4 Networking Capabilities
Network connectivity is bifurcated into a Base-T/Management interface and high-speed data fabric interfaces via PCIe add-in cards.
- **LOM (LAN on Motherboard):** 2x 25GBASE-T (RJ45) for management, Baseboard Management Controller (BMC), and low-latency network access.
- **PCIe Expansion:** The configuration supports up to 4 full-height, full-length PCIe Gen 5 x16 slots. Standard deployment specifies one slot dedicated to networking:
* 4x 10GbE SFP+ Adapter (Standard Deployment) * *Alternative:* 2x 100GbE QSFP28 Adapter (High-Performance Network Deployment)
1.5 Power and Cooling
The TSC platform demands high-efficiency power delivery due to the high TDP components (up to 350W per CPU).
- **PSUs:** Dual redundant (1+1) 2000W 80 PLUS Platinum certified power supplies.
- **Voltage Input:** Supports 100-240V AC, 50/60 Hz.
- **Cooling:** Utilizes high-static-pressure, redundant (N+1) system fans managed by the BMC. Thermal design power (TDP) headroom must be maintained at 20% above the configured CPU TDP envelope, especially when using 128GB DIMMs due to increased thermal density.
2. Performance Characteristics
The performance profile of the TSC is defined by its high core density, massive memory bandwidth, and fast, low-latency storage access via PCIe Gen 5.
2.1 Compute Benchmarks (Synthetic)
The following benchmarks illustrate the potential throughput when the system is configured with dual AMD EPYC 9654 processors (192 Cores total) and 2TB of DDR5-4800 memory.
| Benchmark | Metric | Result (Aggregate) | Context |
|---|---|---|---|
| SPECrate 2017 Integer | Rate (Higher is better) | 1,850 | Measure of throughput for server-side applications. |
| SPECrate 2017 Floating Point | Rate (Higher is better) | 1,920 | Measure of scientific and engineering application throughput. |
| Linpack (HPL) | GFLOPS (Peak Theoretical) | ~ 15.5 TFLOPS | Measured FP64 performance under optimized conditions. |
| Memory Bandwidth (Stream Triad) | GB/s | ~ 650 GB/s | Achievable aggregate read/write bandwidth. |
2.2 I/O Latency and Throughput
Storage performance is heavily dependent on the controller choice and drive technology (NVMe vs. SAS). For the recommended NVMe configuration (16x U.2 Gen 5 drives on a Gen 5 x16 controller):
- **Sequential Read Throughput:** Consistently measured above 55 GB/s.
- **Random Read IOPS (4K Q1/T1):** Exceeds 7 million IOPS.
- **Storage Latency (P99):** Under 15 microseconds for random 4K reads against a well-provisioned RAID-10 equivalent volume.
The 25GbE Base-T interconnects provide approximately 11.5 GB/s throughput per link, while the optional 100GbE cards can deliver near-line-rate performance for high-bandwidth data transfers, crucial for storage virtualization or high-frequency trading environments.
2.3 Power Efficiency (Performance per Watt)
While the maximum power draw can peak near 3.5 kW under full load (CPU stress testing, all drives active), the efficiency under typical virtualization load (60-70% utilization) is excellent due to the high core density.
- **Efficiency Target:** The platform aims for a sustained performance-per-watt ratio exceeding 50 SPECrate/kW at 75% utilization, aligning with Tier III data center energy standards.
3. Recommended Use Cases
The versatility of the TSC makes it suitable for several demanding roles within an enterprise infrastructure stack.
3.1 High-Density Virtualization Host
With up to 224 threads and 4TB of high-speed memory, the TSC excels as a hypervisor host (e.g., VMware ESXi, KVM, Hyper-V).
- **Density:** Capable of safely hosting 250+ standard virtual machines (VMs) with guaranteed minimum resource allocations.
- **NUMA Optimization:** The dual-socket design necessitates careful VM placement to maintain NUMA locality, ensuring high performance for latency-sensitive guest operating systems.
3.2 Database and In-Memory Computing (IMC)
The large memory capacity (up to 4TB) combined with high-speed NVMe storage makes this configuration ideal for large-scale SQL or NoSQL databases.
- **In-Memory Databases:** Configurations approaching 4TB RAM are perfectly suited for massive SAP HANA or specialized time-series databases where the entire working set fits in physical memory.
- **Transactional Workloads (OLTP):** The high IOPS capability of the NVMe array supports rapid commit times and high concurrent transaction rates.
3.3 Application Consolidation and Microservices
For environments heavily invested in containerization (Kubernetes, OpenShift), the TSC provides a dense compute platform.
- **Container Density:** The high core count allows for efficient scheduling of thousands of containers, maximizing resource utilization across the physical hardware.
- **CI/CD Pipelines:** Excellent performance for running large-scale, parallelized build and test automation jobs.
3.4 High-Performance Computing (HPC) Workloads
While specialized accelerators (GPUs) are not mandatory in the base template, the robust CPU and memory subsystem support HPC workloads that are compute-bound rather than massively parallelized (e.g., certain fluid dynamics simulations or Monte Carlo methods). The optional high-speed networking (100GbE) is crucial here for inter-node communication via MPI.
4. Comparison with Similar Configurations
To contextualize the TSC, it is beneficial to compare it against two common alternatives: a Single-Socket (SS) configuration and a High-Density GPU (HPC) configuration.
4.1 Configuration Matrix Comparison
| Feature | Template:ServerConfiguration (TSC) | Single-Socket High-Core (SS-HC) | GPU-Optimized (GPU-Opt) |
|---|---|---|---|
| Socket Count | 2 | 1 | 2 |
| Max Cores (Approx.) | 192 | 64 | 128 (Plus 4-8 Accelerators) |
| Max RAM Capacity | 4 TB | 2 TB | 2 TB (Shared with Accelerators) |
| PCIe Gen 5 Slots (x16) | 4 | 3 | 6-8 (Often sacrificing standard I/O) |
| Primary Strength | Workload Consolidation, I/O Bandwidth | Power Efficiency, Licensing Consolidation | Massive Parallel Compute (AI/ML) |
| Typical Cost Index (Base) | 1.0x | 0.6x | 2.5x (Due to accelerators) |
4.2 Detailed Feature Analysis
- **Versus Single-Socket (SS-HC):** The TSC doubles the total available PCIe lanes (160 vs. 80 lanes, assuming equivalent processor generation), which is the critical differentiator. An SS-HC easily bottlenecks when loading multiple high-speed NVMe arrays or dual 100GbE adapters simultaneously. The TSC mitigates this systemic I/O starvation.
- **Versus GPU-Optimized (GPU-Opt):** The GPU-Opt platform sacrifices general-purpose CPU resources and standard networking slots to accommodate multiple GPUs. While superior for deep learning inference/training, the TSC offers significantly better performance for traditional virtualization, database operations, and tasks that rely heavily on CPU cache and memory bandwidth rather than massive parallel floating-point operations.
5. Maintenance Considerations
Proper maintenance is essential to ensure the thermal envelope and power delivery remain within specification, particularly given the high component density.
5.1 Thermal Management and Airflow
The 2U chassis design requires specific attention to airflow management.
1. **Front-to-Back Airflow:** Ensure a clear path for cool air intake (Zone A) and hot air exhaust (Zone C). Obstructions in the rack aisle can lead to thermal throttling, especially under sustained 100% CPU load. 2. **Component Clearance:** When installing PCIe cards, ensure adequate spacing (minimum 1 slot gap) between high-power adapters (e.g., 300W HBAs or NICs) to prevent localized hotspots that stress the mainboard VRMs. 3. **Fan Redundancy:** Monitor the BMC health status for fan failure alerts. Loss of a single fan may not immediately cause failure, but sustained operation without full fan redundancy significantly reduces the system’s safe operating temperature threshold, potentially forcing the CPUs into lower power states (throttling).
5.2 Power Delivery and Redundancy
The dual 2000W Platinum PSUs provide significant headroom. However, proper PDU configuration is mandatory.
- **Input Requirement:** Each rack unit must be fed from two independent power feeds (A and B sides) sourced from separate UPS systems.
- **Load Balancing:** While the PSUs are redundant, the total measured power draw under peak load should not exceed 1.6 kW per PSU to maintain the Platinum efficiency rating and maximize headroom for transient spikes.
- **Firmware Updates:** Regular updates to the BMC firmware are crucial, as these updates often contain critical thermal profiling adjustments and power state management improvements specific to the installed CPU stepping.
5.3 Serviceability and Component Access
The TSC design prioritizes field-replaceable units (FRUs).
- **Hot-Swap Components:** Drives, PSUs, and system fans are designed for hot-swapping without system shutdown. Always initiate the drive removal sequence via the management interface to ensure the RAID controller has gracefully spun down the spindle or prepared the NVMe for safe removal.
- **Memory Access:** Accessing the DIMM slots requires lifting the top chassis cover and potentially removing the CPU heatsinks (depending on the specific vendor implementation) if servicing slots adjacent to the CPU socket base. This procedure must be performed in a controlled, ESD-safe environment.
5.4 Operating System and Driver Support
The platform relies heavily on up-to-date OS kernel support for optimal performance, particularly concerning memory management and PCIe Gen 5 capabilities.
- **Storage Drivers:** Use certified vendor drivers for the RAID controller (e.g., Broadcom/LSI) that specifically enable the full throughput of Gen 5 NVMe devices. Generic OS drivers may limit performance to Gen 4 speeds.
- **NUMA Awareness:** Ensure the hypervisor or OS scheduler is fully NUMA-aware to prevent cross-socket memory access penalties, which can degrade performance by up to 30% in memory-bound workloads.
