1. Hardware Specifications

The "Billing Systems" server configuration is designed for high-throughput, low-latency transaction processing, data integrity, and scalability required by modern billing applications. This configuration prioritizes reliability and data security. It is intended for handling complex billing cycles, subscription management, and financial reporting. The following details the hardware components:

1.1. CPU

  • **Model:** Dual Intel Xeon Gold 6338 (32 Cores/64 Threads per CPU)
  • **Base Clock Speed:** 2.0 GHz
  • **Turbo Boost Max 3.0:** 3.4 GHz
  • **Cache:** 48 MB Intel Smart Cache per CPU
  • **TDP:** 205W per CPU
  • **Instruction Set Extensions:** AVX-512, Intel Deep Learning Boost (Intel DL Boost) with VNNI
  • **Socket:** LGA 4189
  • **Rationale:** The dual Xeon Gold processors provide a significant number of cores and threads for parallel processing of billing calculations, data aggregation, and report generation. AVX-512 accelerates computationally intensive tasks, and Intel DL Boost enhances performance for machine learning-based fraud detection or usage prediction (see Server CPU Selection).

1.2. Memory (RAM)

  • **Capacity:** 512 GB DDR4-3200 ECC Registered DIMMs
  • **Configuration:** 16 x 32 GB DIMMs
  • **Channels:** 8 channels per CPU (total 16 channels)
  • **Speed:** 3200 MHz
  • **ECC:** Error-Correcting Code (ECC) Registered
  • **Rank:** Dual Rank
  • **Rationale:** Large memory capacity is crucial for in-memory databases and caching frequently accessed billing data, reducing latency and improving overall performance. ECC Registered DIMMs ensure data integrity and system stability, vital for financial transactions (see Server Memory Technologies). The 8-channel architecture maximizes memory bandwidth.

1.3. Storage

  • **Operating System/Boot Drive:** 2 x 400 GB NVMe PCIe Gen4 SSD (RAID 1)
  • **Database Storage:** 8 x 4 TB SAS 12 Gbps 7.2K RPM Enterprise HDD (RAID 6)
  • **Log Storage:** 2 x 1.6 TB NVMe PCIe Gen4 SSD (RAID 1)
  • **Backup Storage Interface:** Dedicated 100GbE connection to a network attached storage (NAS) solution (see Server Storage Options)
  • **Rationale:** The dual NVMe SSDs for the OS and boot provide fast boot times and responsiveness. RAID 1 mirroring offers redundancy. The SAS HDDs in RAID 6 provide a balance of capacity, performance, and redundancy for the core database. Separate NVMe SSDs for logs ensure fast write speeds, preventing bottlenecks during high transaction volumes. The dedicated 100GbE connection to the NAS is for offsite data protection.

1.4. Network Interface Cards (NICs)

  • **Primary NIC:** Dual 100 Gigabit Ethernet (100GbE) QSFP28 ports
  • **Secondary NIC:** Quad 10 Gigabit Ethernet (10GbE) SFP+ ports
  • **Teaming/Bonding:** NIC Teaming configured for both 100GbE and 10GbE interfaces
  • **Rationale:** High-bandwidth networking is essential for handling a large volume of billing transactions and efficient data transfer. 100GbE provides the necessary throughput for peak loads. NIC Teaming provides redundancy and increased bandwidth (see Server Networking Fundamentals).

1.5. Power Supply Units (PSUs)

  • **Capacity:** 2 x 1600W 80+ Platinum Certified Redundant Power Supplies
  • **Input Voltage:** 200-240V AC
  • **Output Voltage:** 12V, 5V, 3.3V
  • **Rationale:** Redundant power supplies ensure continuous operation in the event of a PSU failure. 80+ Platinum certification ensures high energy efficiency, reducing operating costs (see Server Power Management).

1.6. Chassis and Cooling

  • **Form Factor:** 2U Rackmount Server
  • **Cooling:** Redundant Hot-Swappable Fans with N+1 redundancy
  • **Airflow:** Front-to-Back airflow
  • **Rationale:** The 2U form factor balances density and cooling capacity. Redundant hot-swappable fans provide reliable cooling, and front-to-back airflow optimizes heat dissipation (see Server Cooling Solutions).

1.7. RAID Controller

  • **Model:** Hardware RAID controller with 8GB cache and RAID 6 support.
  • **Interface:** PCIe 4.0 x8
  • **Rationale:** Hardware RAID controllers offer superior performance compared to software RAID and provide robust data protection.
