Understanding Server Power Consumption
In today's digital-first world, servers play a pivotal role in powering businesses, applications, and the vast landscape of the internet. However, as much as they are essential, servers are also significant consumers of power, raising concerns over operational costs and environmental impact. This article delves into the intricacies of server power usage, offering insights into how much power servers typically consume and providing strategies for optimizing energy efficiency.
To address the needs of modern businesses Bargain Hardware offers refurbished servers with modern energy-saving features, providing cost-effective options that consume less power. By leveraging Bargain Hardware's huge inventory and configuration options, companies can mitigate power costs and environmental footprint without compromising performance.
Server Power Consumption: The Basics
Server power usage can vary widely depending on several factors, including the type of server, its configuration, workload, and operational environment. On average, a standard rack server might consume anywhere from 500 to 1200 watts under normal operational conditions. However, high-performance models designed for intensive computing tasks can demand significantly more, with consumption rates exceeding 2000 watts.
Factors Influencing Server Power Use
- Server Type and Configuration: The specific model and build of a server play a crucial role in its power consumption. High-capacity servers equipped with multiple processors, extensive memory, and large storage arrays will invariably use more power than smaller, less equipped models.
- Workload: The nature and intensity of the tasks performed by a server directly impact its energy use. Servers running high-compute applications, such as database management systems or large-scale virtualization platforms, will consume more power due to the increased processor and memory activity.
- Operational Environment: The conditions in which a server operates, including ambient temperature and cooling requirements, also affect power consumption. Servers in hotter environments may require more power for cooling to maintain optimal performance temperatures.

We tested two of our most popular HP and Dell refurbished servers. Both servers were tested under the same conditions using power saving (or power balanced) mode, and again in max cooling mode:
*** All servers tested are 8 bay models, with 2 x Intel Xeon Gold 6134 processors, 192GB DDR4 RAM, 6 x 1.2TB HDD, 2 x NVMe SSD 1.92TB:
HP Proliant DL360 Gen10 8SFF | 2 x Xeon Gold 6134 | 192GB 2666V-R RAM | P408i-a | 366FLR | 2 x 1400W PSU | 2 x 1.92 Samsung NVMe SSD | 6 x 1.2TB HDD SFF | 8x Caddy | BIOS version: V2.80 | Ilo version: V2.91
Dell PowerEdge R640 8SFF| 2 x Xeon Gold 6134 | 192GB 2666V-R RAM | H740 | RNDC i350 | 2 x 1100W PSU | Intel i350 Pcie | 2 x 1.92 Samsung NVMe SSD | 6 x 1.2TB HDD SFF | 8x Caddy | BIOS version: 2.18.1 | iDRAC: 6.10.80.00
Upon testing, the HP ProLiant DL360 Gen10 and Dell PowerEdge R640 servers has yielded significant insights regarding their power consumption profiles. The data illustrates a clear distinction in energy usage between power-saving and maximum cooling modes, with the HP server showcasing a noticeable uptick in power consumption when transitioning from an energy-efficient mode to a performance-oriented cooling approach. This underscores the importance of carefully selecting the appropriate server and operational configuration to align with specific power consumption and cooling requirements. Conversely, the Dell server exhibits a more consistent power consumption pattern in power-saving mode, yet it signals potential spikes in power usage under heavy workloads when operating in maximum cooling mode. These findings serve as critical guidance for IT professionals seeking to strike a balance between server efficiency and power consumption management.
Strategies for Optimizing Server Power Efficiency
- Right-Sizing Server Infrastructure: Ensure that your server setup is appropriately sized for your needs. Over-provisioning leads to unnecessary power consumption, while under-provisioning can cause overloading and inefficiency. Regularly assess your server requirements and adjust as necessary.
- Leveraging Modern Hardware: Newer server models are often designed with energy efficiency in mind, incorporating advanced power management features that can significantly reduce consumption. When possible, upgrade to hardware that offers better performance per watt.
- Implementing Virtualization: Virtualization allows multiple virtual servers to run on a single physical server, maximizing hardware utilization and reducing the need for additional physical servers. This consolidation can lead to substantial energy savings.
- Optimizing Cooling Systems: Efficient cooling is paramount in managing server energy use. Invest in advanced cooling solutions and consider the layout of your server room to enhance airflow and reduce cooling-related power consumption.
- Monitoring and Management Tools: Utilize software tools to monitor server performance and energy usage actively. These tools can help identify inefficiencies and areas for improvement, allowing for more informed decisions regarding energy management.
The Role of Refurbished Servers in Energy Efficiency
Refurbished servers from reputable suppliers like Bargain Hardware present an opportunity to access high-quality hardware at a fraction of the cost of new equipment. These servers often come with modern energy-saving features, making them an attractive option for businesses looking to optimize their IT infrastructure's power efficiency without compromising on performance or reliability.
Moreover, choosing refurbished servers contributes to the circular economy, extending the life of valuable IT assets and reducing the environmental impact associated with manufacturing new equipment.
Conclusion
Managing server power consumption is a multifaceted challenge that requires a strategic approach. By understanding the factors that influence energy use and implementing efficiency measures, businesses can significantly reduce their operational costs and environmental footprint. Refurbished servers offer a cost-effective and environmentally friendly solution for achieving these goals, providing the performance needed with a lower power consumption profile.
As the digital landscape continues to evolve, the importance of energy-efficient server infrastructure cannot be overstated. With the right strategies and a commitment to sustainability, organizations can ensure their servers power their success without draining resources unnecessarily.
