Overview
This document details the hardware and operational characteristics of a server configuration designed to optimize cost-effectiveness in cloud computing environments. This configuration, dubbed “CostOptima,” prioritizes price-performance ratio, focusing on balancing compute power, memory capacity, and storage options to deliver a compelling solution for a wide range of cloud workloads. It is geared towards providers aiming to reduce Total Cost of Ownership (TCO) without significant performance compromises, and for end-users seeking cost-optimized instances. This configuration is suitable for applications that can tolerate slightly lower peak performance in exchange for significantly lower operational expenses. We will examine the hardware specifications, performance benchmarks, recommended use cases, competitive positioning, and essential maintenance considerations.
1. Hardware Specifications
The CostOptima configuration is built around a blend of current and slightly older-generation components selected for their price/performance ratio. The goal is to avoid bleeding-edge technology (which commands premium pricing) while retaining sufficient processing power and capacity for common cloud workloads.
CPU: Dual Intel Xeon Gold 6248R (24 cores/48 threads per CPU, 3.0 GHz base frequency, 3.7 GHz boost frequency). These CPUs represent a strong value proposition, offering a significant core count at a competitive price point. They are based on the Cascade Lake architecture. CPU Architecture Considerations are vital to understanding the limitations and strengths of this choice.
RAM: 256 GB DDR4-2933 ECC Registered DIMMs (16 x 16GB). Utilizing Registered DIMMs (RDIMMs) is crucial for server stability and memory addressability at this capacity. The 2933 MHz speed provides a good balance between performance and cost. Memory Technologies provides a detailed breakdown of RAM types.
Storage:
- Boot Drive: 480GB NVMe PCIe Gen3 x4 SSD (Read: 3500 MB/s, Write: 3000 MB/s). This provides fast boot times and responsiveness for the operating system.
- Primary Storage: 4 x 4TB SAS 12Gb/s 7.2K RPM HDD in RAID 10 configuration. RAID 10 provides excellent performance and data redundancy. While SSDs offer higher performance, the cost per terabyte of SAS HDDs makes them more economical for large-capacity storage needs. RAID Configurations details the benefits and drawbacks of different RAID levels.
- Optional Cache Tier: 1TB NVMe PCIe Gen3 x4 SSD (Read: 3200 MB/s, Write: 2500 MB/s). This can be added as a read/write cache in front of the SAS HDDs to accelerate frequently accessed data. Storage Tiering explains the benefits of this approach.
Networking: Dual 10 Gigabit Ethernet (10GbE) ports with Broadcom BCM57416 network controllers. 10GbE provides sufficient bandwidth for most cloud workloads. Network Interface Cards further details NIC options.
Motherboard: Supermicro X11DPG-QT. A dual-socket motherboard supporting the Intel Xeon Scalable processors and ample PCIe lanes for expansion. Server Motherboard Design provides details on key motherboard features.
Power Supply: 2 x 800W 80+ Platinum Certified Redundant Power Supplies. Redundancy ensures uptime in case of PSU failure. Platinum certification guarantees high energy efficiency. Power Supply Units details PSU characteristics.
Chassis: 2U Rackmount Chassis. A standard 2U form factor allows for efficient rack density. Server Chassis Types details various form factors.
Remote Management: IPMI 2.0 compliant with dedicated LAN port. Allows for remote server management and monitoring. IPMI and Remote Management provides a deep dive into remote server administration.

The optional SSD cache can significantly improve read performance for frequently accessed data. Storage Performance Analysis details methodologies for storage benchmarking.
- FIO: 4KB Random Read/Write: 50,000 IOPS (approximate).
Network Benchmarks:
- iperf3: Sustained throughput of approximately 9.4 Gbps (close to the theoretical maximum of 10GbE).
Real-World Performance:
- Web Server (Apache/Nginx): Capable of handling approximately 5,000 concurrent requests with reasonable latency.
- Database Server (MySQL/PostgreSQL): Performance is adequate for small to medium-sized databases. Larger databases may require additional caching or a more powerful storage solution. Database Server Optimization offers guidance on improving database performance.
- Virtualization (KVM/Xen): Supports a moderate number of virtual machines (approximately 20-30) depending on the resource requirements of each VM. Virtual Machine Management details best practices for virtualized environments.
Performance Limitations: The primary performance bottleneck is the SAS HDD-based storage. While RAID 10 mitigates some performance issues, it cannot match the speed of all-flash storage. The CPU, while powerful, is not the latest generation and will be outperformed by newer processors.
3. Recommended Use Cases
The CostOptima configuration is well-suited for the following use cases:
- Web Hosting (Shared & VPS): Provides a cost-effective platform for hosting websites and virtual private servers.
