Top 5 Server Efficiency Strategies: Boost Your Data Center

In data centers, where energy efficiency and sustainability are paramount, optimizing server performance has become a critical focus for enterprises worldwide. Servers, often the backbone of these data centers, account for a substantial portion of energy consumption. To address this challenge, organizations are embracing innovative strategies, as highlighted by recent research from the Uptime Institute. Here, we delve into the nuanced approaches and tangible benefits of enhancing server efficiency in the modern digital era.

#1. Upgrade to the Latest Server Generation:

Upgrading servers to the latest generation is a strategic move toward enhanced efficiency. The evolution of processor technology, particularly in AMD EPYC and Intel Xeon processors, has led to substantial gains. For instance, Intel servers experienced a commendable 34% improvement in efficiency between 2017 and 2019, showcasing the rapid advancements in processor efficiency. 

AMD-based servers, on the other hand, made an astonishing leap, boasting a staggering 140% improvement during the same period. Moving further, the transition to 2021 servers yields remarkable results, with AMD servers surpassing Intel servers by an impressive 74% at 50% utilization. These figures underscore the transformative impact of upgrading to the latest server technology, not only in terms of energy efficiency but also overall performance.

#2. Right-sizing Workloads and Increasing Utilization:

The Uptime Institute’s survey has brought to light a significant concern within the realm of server management – the underutilization of servers. The survey revealed that only 47% of companies managed to achieve a server utilization rate of 50% or higher. This statistic highlights a prevalent inefficiency in data centers where resources are not optimally utilized.

Optimizing workload utilization is a strategic approach to address this issue. By increasing server utilization, especially during off-peak hours, companies can significantly enhance efficiency. When coupled with strategic server upgrades, this dynamic approach has the potential to more than double efficiency rates. The impact of this optimization extends beyond mere efficiency gains; it translates into substantial capital and operational savings for organizations. By aligning server utilization with workload demands, companies can maximize the value derived from their server infrastructure.

#3. Invest in More Powerful Machines:

Investing in higher capacity servers, especially those powered by AMD processors, plays a pivotal role in enhancing energy efficiency. The efficiency gains are particularly remarkable when server work capacity is increased. For instance, AMD servers, capable of handling more than eight million SSJs (Server-Side Java operations), demonstrate a doubling of server efficiency. This exemplifies the substantial benefits derived from upgrading to higher capacity AMD servers.

Even in the case of Intel servers, although the efficiency benefits are slightly less dramatic compared to AMD, upgrading to higher capacity machines contributes significantly to improved efficiency. The inherent message here is clear: investing in more powerful servers directly translates into enhanced energy efficiency. By embracing advanced server technology, organizations can optimize their operations, reduce energy consumption, and elevate overall efficiency standards.

#4. Increase Server Core Count:

The role of processor cores in server efficiency cannot be overstated. Uptime Institute’s research underscores the significance of this factor, particularly in the context of 2021 AMD servers. According to their findings, increasing the number of cores from eight to 64 results in a remarkable tripling of efficiency. This exponential improvement demonstrates the critical role core count plays in enhancing the overall efficiency of servers.

While increasing core count is pivotal, it’s equally essential to align core counts with specific workload requirements. This strategic approach ensures that computational resources are utilized optimally, preventing underutilization or overburdening of cores. Moreover, maximizing core usage through technologies like hypervisors and virtual machines further amplifies efficiency. These virtualization methods enable servers to handle multiple tasks concurrently, leveraging the full potential of each core.

#5. Implement Effective Power Management:

Effective power management stands as a cornerstone in the pursuit of energy-efficient server operations. Uptime Institute’s research indicates that implementing robust power management features can boost server efficiency by at least 10%. This improvement is achieved through meticulous adjustments in CPU voltage, frequency, and leveraging idle states for unused cores.

However, concerns about latency often deter organizations from fully embracing power management features. It’s crucial to acknowledge these concerns while also recognizing that rigorous testing and careful implementation can address latency challenges effectively. By conducting thorough tests and ensuring meticulous implementation, organizations can strike a balance between energy savings and optimal server performance.

Uptime Institute’s In-Depth Server Efficiency Analysis

Uptime Institute assessed the efficiency of 429 server platforms using The Green Grid’s Server Efficiency Rating Tool (SERT) database. The Green Grid, a consortium dedicated to enhancing energy and resource efficiency in data centers, developed SERT as an industry standard for measuring server efficiency. Mandated by the EU’s Ecodesign Directive and the US Energy Star program, servers are required to report the SERT overall efficiency metric.

Uptime’s analysis focused on servers utilizing AMD EPYC or Intel Xeon processors from 2017, 2019, and 2021. Different processor types exhibit various strengths and weaknesses based on the workload they handle. To conduct the assessment, Uptime simulated an enterprise online transaction-processing application using the SERT worklet server-side Java (SSJ). This simulation stressed both processors and memory. The SSJ data allowed Uptime to evaluate server efficiency across a granular spectrum of utilization levels, ranging from 12.5% to 100%.

By scrutinizing this detailed data, Uptime Institute gained valuable insights into the performance and efficiency of servers, enabling a comprehensive analysis of the energy efficiency landscape within the server industry. This meticulous evaluation forms the foundation of their research, providing essential information for businesses striving to optimize their server infrastructure.

Conclusion: 

In the pursuit of sustainability and energy efficiency, organizations must adopt a holistic approach. Upgrading hardware, optimizing workloads, and implementing effective power management are interconnected strategies that, when employed synergistically, revolutionize server efficiency. These advancements not only align with environmental goals but also enhance operational efficiency, reduce costs, and pave the way for a more sustainable digital future.

By embracing these strategies, businesses can transform their data centers into energy-efficient powerhouses, ensuring a greener, more sustainable tomorrow for the entire industry.
