- Cost Optimization for Server Infrastructure
Introduction
This document details a server configuration specifically designed for cost optimization while maintaining acceptable performance for a range of workloads. This configuration focuses on maximizing performance per dollar spent, leveraging current market trends in component pricing, and prioritizing efficiency. It's targeted towards businesses looking to reduce capital expenditure (CAPEX) and operational expenditure (OPEX) related to their server infrastructure. This document will cover hardware specifications, performance characteristics, recommended use cases, comparisons with similar configurations, and essential maintenance considerations. We will also link to relevant internal documentation on related topics such as Power Usage Effectiveness (PUE), Server Virtualization, and Data Center Cooling.
1. Hardware Specifications
This configuration aims for a balance between compute, memory, and storage, focusing on maximizing value. Component choices are driven by current market pricing as of Q4 2023. It's designed as a 1U rack server, leveraging the density benefits of rack-mounted solutions.
1.1 Processor (CPU)
- Model: AMD EPYC 7313 (2.0 GHz base clock, up to 3.0 GHz boost clock)
- Cores/Threads: 16 cores / 32 threads
- Cache: 128 MB Total Cache (L3)
- TDP: 155W
- Socket: SP3
- Rationale: AMD EPYC processors offer a compelling price-to-performance ratio compared to Intel Xeon options in this segment. The 7313 provides a good balance of core count and clock speed for most workloads. Refer to CPU Comparison Guide for a deeper dive into processor architectures.
1.2 Motherboard
- Form Factor: 1U Rack Server Motherboard
- Chipset: AMD SP3 Chipset
- RAM Slots: 8 x DDR4 DIMM slots
- Expansion Slots: 1 x PCIe 4.0 x16, 1 x PCIe 4.0 x8, 1 x M.2 slot (for boot drive)
- Network Interface: Dual 1 Gigabit Ethernet ports (Intel I350-T4)
- Rationale: A standard 1U server motherboard featuring the SP3 chipset provides compatibility with the chosen EPYC processor and offers sufficient expansion capabilities. The integrated NICs are adequate for basic network connectivity, but upgrades may be necessary for high-bandwidth applications (see Network Interface Card Options).
1.3 Memory (RAM)
- Type: DDR4 ECC Registered
- Capacity: 128 GB (8 x 16GB modules)
- Speed: 3200 MHz
- Configuration: Dual-channel per memory bank
- Rationale: 128GB provides sufficient memory for most virtualized environments and demanding applications. ECC Registered memory ensures data integrity, crucial for server stability. Utilizing 3200MHz maximizes bandwidth within the budget constraints. Consult Memory Configuration Best Practices for optimal memory setup.
1.4 Storage
- Boot Drive: 512GB NVMe PCIe Gen3 x4 SSD
- OS Drive: 1TB SATA III SSD
- Data Storage: 8 x 8TB SATA III 7200RPM Hard Disk Drives (HDDs) in RAID 6 configuration.
- RAID Controller: Hardware RAID Controller with 2GB Cache (supports RAID 0, 1, 5, 6, 10)
- Rationale: A tiered storage approach balances performance and cost. The NVMe SSD provides fast boot times, the SATA SSD handles the operating system, and the HDDs provide bulk storage. RAID 6 offers excellent data redundancy with the ability to withstand two simultaneous drive failures. See Storage Technologies Overview for detailed information on RAID levels and SSD/HDD comparison.
1.5 Power Supply
- Capacity: 750W Redundant Power Supplies (1+1 configuration)
- Efficiency: 80+ Platinum Certified
- Form Factor: 1U
- Rationale: Redundant power supplies ensure high availability. 80+ Platinum certification maximizes energy efficiency, reducing OPEX. The 750W capacity provides sufficient headroom for the components and future upgrades. Refer to Power Supply Selection Guide for more details.
1.6 Network Interface Card (NIC)
- Primary NIC: Dual 1GbE (as integrated on the motherboard)
- Optional Upgrade: 10GbE NIC (Intel X710-DA4) – for higher bandwidth requirements.
- Rationale: The integrated NICs are sufficient for basic network connectivity. However, a 10GbE NIC upgrade is recommended for applications requiring high throughput.
1.7 Chassis
- Form Factor: 1U Rackmount Chassis
- Material: Steel
- Cooling: Hot-swappable fan modules with redundant fans.
- Rationale: A standard 1U chassis maximizes server density in a rack. Redundant fans ensure reliable cooling. See Server Cooling Strategies for a comprehensive overview of thermal management.
