L3 Cache (Total) 36 MB Minimum 64 MB Minimum
Supported Memory Channels 6 or 8 Channels per socket 8 Channels per socket (for optimal I/O)

The selection of the CPU generation is crucial; while older generations may fit the "stub" moniker, modern stability and feature sets (such as AVX-512 or PCIe 4.0 support) are mandatory for baseline compatibility with contemporary operating systems and hypervisors.

1.2. Random Access Memory (RAM)

Memory capacity and speed are provisioned to support moderate virtualization density or large in-memory datasets typical of database caching layers. The configuration specifies DDR4 ECC Registered DIMMs (RDIMMs) or Load-Reduced DIMMs (LRDIMMs) depending on the required density ceiling.

Template:Stub Memory Configuration
Specification Detail
Type DDR4 ECC RDIMM/LRDIMM (DDR5 requirement for future revisions)
Total Capacity (Minimum) 128 GB
Total Capacity (Recommended) 256 GB
Configuration Strategy Fully populated memory channels (e.g., 8 DIMMs per CPU or 16 total)
Speed Rating (Minimum) 2933 MT/s
Speed Rating (Recommended) 3200 MT/s (or fastest supported by CPU/Motherboard combination)

It is critical that the BIOS/UEFI is configured to utilize the maximum supported memory speed profile (e.g., XMP or JEDEC profiles) while maintaining stability under full load, adhering strictly to the Memory Interleaving guidelines for the specific motherboard chipset.

1.3. Storage Subsystem

The storage configuration emphasizes a tiered approach: a high-speed boot/OS volume and a larger, redundant capacity volume for application data. Direct Attached Storage (DAS) is the standard implementation.

Template:Stub Storage Layout (DAS)
Tier Component Type Quantity Capacity (per unit) Interface/Protocol
Boot/OS NVMe M.2 or U.2 SSD 2 (Mirrored) 480 GB Minimum PCIe 3.0/4.0 x4
Data/Application SATA or SAS SSD (Enterprise Grade) 4 to 6 1.92 TB Minimum SAS 12Gb/s (Preferred) or SATA III
RAID Controller Hardware RAID (e.g., Broadcom MegaRAID) 1 N/A PCIe 3.0/4.0 x8 interface required

The data drives must be configured in a RAID 5 or RAID 6 array for redundancy. The use of NVMe for the OS tier significantly reduces boot times and metadata access latency, a key improvement over older SATA-based stub configurations. Refer to RAID Levels documentation for specific array geometry recommendations.

1.4. Networking and I/O

Standardization on 10 Gigabit Ethernet (10GbE) is required for the management and primary data interfaces.

Template:Stub Networking and I/O
Component Specification Purpose
Primary Network Interface (Data) 2 x 10GbE SFP+ or Base-T (Configured in LACP/Active-Passive) Application Traffic, VM Networking
Management Interface (Dedicated) 1 x 1GbE (IPMI/iDRAC/iLO) Out-of-Band Management
PCIe Slots Utilization At least 2 x PCIe 4.0 x16 slots populated (for future expansion or high-speed adapters) Expansion for SAN connectivity or specialized accelerators

The onboard Baseboard Management Controller (BMC) must support modern standards, including HTML5 console redirection and secure firmware updates.

1.5. Power and Form Factor

The configuration is designed for high-density rack deployment.

  • **Form Factor:** 2U Rackmount Chassis (Standard 19-inch width).
  • **Power Supplies (PSUs):** Dual Redundant, Hot-Swappable, Platinum or Titanium Efficiency Rating (>= 92% efficiency at 50% load).
  • **Total Rated Power Draw (Peak):** Approximately 850W – 1100W (dependent on CPU TDP and storage configuration).
  • **Input Voltage:** 200-240V AC (Recommended for efficiency, though 110V support must be validated).

2. Performance Characteristics

The performance profile of the Template:Stub is defined by its balanced memory bandwidth and core count, making it a suitable platform for I/O-bound tasks that require moderate computational throughput.

2.1. Synthetic Benchmarks (Estimated)

The following benchmarks reflect expected performance based on the recommended component specifications (Ice Lake/Milan generation CPUs, 3200MT/s RAM).

Template:Stub Estimated Synthetic Performance
Benchmark Area Metric Expected Result Range Notes
CPU Compute (Integer/Floating Point) SPECrate 2017 Integer (Base) 450 – 550 Reflects multi-threaded efficiency.
Memory Bandwidth (Aggregate) Read/Write (GB/s) 180 – 220 GB/s Dependent on DIMM population and CPU memory controller quality.
Storage IOPS (Random 4K Read) Sustained IOPS (from RAID 5 Array) 150,000 – 220,000 IOPS Heavily influenced by RAID controller cache and drive type.
Network Throughput TCP/IP Throughput (iperf3) 19.0 – 19.8 Gbps (Full Duplex) Testing 2x 10GbE bonded link.

The key performance bottleneck in the Stub configuration, particularly when running high-vCPU density workloads, is often the memory subsystem's latency profile rather than raw core count, especially when the operating system or application attempts to access data across the Non-Uniform Memory Access boundary between the two sockets.

2.2. Real-World Performance Analysis

The Stub configuration excels in scenarios demanding high I/O consistency rather than peak computational burst capacity.

  • **Database Workloads (OLTP):** Handles transactional loads requiring moderate connections (up to 500 concurrent active users) effectively, provided the working set fits within the 256GB RAM allocation. Performance degradation begins when the workload triggers significant page faults requiring reliance on the SSD tier.
  • **Web Serving (Apache/Nginx):** Capable of serving tens of thousands of concurrent requests per second (RPS) for static or moderately dynamic content, limited primarily by network saturation or CPU instruction pipeline efficiency under heavy SSL/TLS termination loads.
  • **Container Orchestration (Kubernetes Node):** Functions optimally as a worker node supporting 40-60 standard microservices containers, where the CPU cores provide sufficient scheduling capacity, and the 10GbE networking allows for rapid service mesh communication.

3. Recommended Use Cases

The Template:Stub configuration is not intended for high-performance computing (HPC) or extreme data analytics but serves as an excellent foundation for robust, general-purpose infrastructure.

3.1. Virtualization Host (Mid-Density)

This configuration is ideal for hosting a consolidated environment where stability and resource isolation are paramount.

  • **Target Density:** 8 to 15 Virtual Machines (VMs) depending on the VM profile (e.g., 8 powerful Windows Server VMs or 15 lightweight Linux application servers).
  • **Hypervisor Support:** Full compatibility with VMware vSphere, Microsoft Hyper-V, and Kernel-based Virtual Machine.
  • **Benefit:** The dual-socket architecture ensures sufficient PCIe lanes for multiple virtual network interface cards (vNICs) and provides ample physical memory for guest allocation.

3.2. Application and Web Servers

For standard three-tier application architectures, the Stub serves well as the application or web tier.

  • **Backend API Tier:** Suitable for hosting RESTful services written in languages like Java (Spring Boot), Python (Django/Flask), or Go, provided the application memory footprint remains within the physical RAM limits.
  • **Load Balancing Target:** Excellent as a target for Network Load Balancing (NLB) clusters, offering predictable latency and throughput.

3.3. Jump Box / Bastion Host and Management Server

Due to its robust, standardized hardware, the Stub is highly reliable for critical management functions.

  • **Configuration Management:** Running Ansible Tower, Puppet Master, or Chef Server. The storage subsystem provides fast configuration deployment and log aggregation.
  • **Monitoring Infrastructure:** Hosting Prometheus/Grafana or ELK stack components (excluding large-scale indexing nodes).

3.4. File and Backup Target

When configured with a higher count of high-capacity SATA/SAS drives (exceeding the 6-drive minimum), the Stub becomes a capable, high-throughput Network Attached Storage (NAS) target utilizing technologies like ZFS or Windows Storage Spaces.

4. Comparison with Similar Configurations

To contextualize the Template:Stub, it is useful to compare it against its immediate predecessors (Template:Legacy) and its successors (Template:HighDensity).

4.1. Configuration Matrix Comparison

Configuration Comparison Table
Feature Template:Stub (Baseline) Template:Legacy (10/12 Gen Xeon) Template:HighDensity (1S/HPC Focus)
CPU Sockets 2P 2P 1S (or 2P with extreme core density)
Max RAM (Typical) 256 GB 128 GB 768 GB+
Primary Storage Interface PCIe 4.0 NVMe (OS) + SAS/SATA SSDs PCIe 3.0 SATA SSDs only All NVMe U.2/AIC
Network Speed 10GbE Standard 1GbE Standard 25GbE or 100GbE Mandatory
Power Efficiency Rating Platinum/Titanium Gold Titanium (Extreme Density Optimization)
Cost Index (Relative) 1.0x 0.6x 2.5x+

The Stub configuration represents the optimal point for balancing current I/O requirements (10GbE, PCIe 4.0) against legacy infrastructure compatibility, whereas the Template:Legacy is constrained by slower interconnects and less efficient power delivery.

4.2. Performance Trade-offs

The primary trade-off when moving from the Stub to the Template:HighDensity configuration involves the shift from balanced I/O to raw compute.

  • **Stub Advantage:** Superior I/O consistency due to the dedicated RAID controller and dual-socket memory architecture providing high aggregate bandwidth.
  • **HighDensity Disadvantage (in this context):** Single-socket (1S) high-density configurations, while offering more cores per watt, often suffer from reduced memory channel access (e.g., 6 channels vs. 8 channels per CPU), leading to lower sustained memory bandwidth under full virtualization load.

5. Maintenance Considerations

Maintaining the Template:Stub requires adherence to standard enterprise server practices, with specific attention paid to thermal management due to the dual-socket high-TDP components.

5.1. Thermal Management and Cooling

The dual-socket design generates significant heat, necessitating robust cooling infrastructure.

  • **Airflow Requirements:** Must maintain a minimum front-to-back differential pressure of 0.4 inches of water column (in H2O) across the server intake area.
  • **Component Specifics:** CPUs rated above 150W TDP require high-static pressure fans integrated into the chassis, often exceeding the performance of standard cooling solutions designed for single-socket, low-TDP hardware.
  • **Hot Aisle Containment:** Deployment within a hot-aisle/cold-aisle containment strategy is highly recommended to maximize chiller efficiency and prevent thermal throttling, especially during peak operation when all turbo frequencies are engaged.

5.2. Power Requirements and Redundancy

The redundant power supplies (N+1 or 2N configuration) must be connected to diverse power paths whenever possible.

  • **PDU Load Balancing:** The total calculated power draw (approaching 1.1kW peak) means that servers should be distributed across multiple Power Distribution Units (PDUs) to avoid overloading any single circuit breaker in the rack infrastructure.
  • **Firmware Updates:** Regular firmware updates for the BMC, BIOS/UEFI, and RAID controller are mandatory to ensure compatibility with new operating system kernels and security patches (e.g., addressing Spectre variants).

5.3. Operating System and Driver Lifecycle

The longevity of the Stub configuration relies heavily on vendor support for the chosen CPU generation.

  • **Driver Validation:** Before deploying any major OS patch or hypervisor upgrade, all hardware drivers (especially storage controller and network card firmware) must be validated against the vendor's Hardware Compatibility List (HCL).
  • **Diagnostic Tools:** The BMC must be configured to stream diagnostic logs (e.g., Intelligent Platform Management Interface sensor readings) to a central System Monitoring platform for proactive failure prediction.

The stability of the Template:Stub ensures that maintenance windows are predictable, typically only required for major component replacements (e.g., PSU failure or expected drive rebuilds) rather than frequent stability patches.
