Exploring the Differences: Dell PowerEdge R750 vs. R750xs

In the area of enterprise servers, Dell's PowerEdge series stands out for its robust performance, reliability, and scalability. The Dell PowerEdge R750 and R750xs are two noteworthy server models withing Dell's lineup, each designed to meet specific business needs. While both servers are built on the same technology foundation, they exhibit distinct features and capabilities. In this article we will dive into the nuanced differences between the R750 and the R750xs, and why Dell even created this two different models in the first place, and the guidance given to businesses in choosing the right Dell PowerEdge R750 or R750xs server for their IT infrastructure.

Performance and Processor Options

The Dell PowerEdge R750 and R750xs are both powered by the 3rd generation of Intel Xeon Scalable processors, which provide a substantial performance gains for various workloads. The R750xs is a versatile server server capable of handling a wide range of tasks, from virtualization to medium-scale databases. It offers a balance performance, memory capacity and storage.
In contrast, the R750 is engineered for more extensive workloads, featuring higher core count, up to 40 Cores, and faster memory speeds and capacities. This model is particularly well-suited for high-performance computing (HPC), large-scale virtualization, and demanding data analytics applications. The R750's enhanced processing power makes it the preferred choice for scenarios requiring maximum computational throughput.

Memory and Storage

Both the R750 and R750xs support a significant amount of memory; however, the R750 often provides greater memory speeds and capacity, as well as the full support for Intel Optane memory, catering to memory intensive applications. When it comes to storage, the R750xs offers a range of options that can be tailored to meet the needs of various applications, supporting a mix of solid state drives and hard drive types, capacities, and transfer speeds.
On the other side, the R750 pushes the boundaries with its storage capabilities, offering more drive bays (mid flex bay) and support for high-performance NVMe drives as it highest bay count can reach to 24 drive Bays with NVMe drives. This makes an excellent choice for tasks that demand high-speed storage access and data transfer, such as real-time data analytics and large-scale database applications.

Expandability and Networking

Expandability is a key consideration in server selection, and both R750 and R750xs offer extensive options. The R750, however, typically provides more PCI Express (PCIe) slots and enhanced networking capabilities, including higher-speed network interfaces and more network cards. This is crucial for environments where network throughput and low latency are essential, such as in cloud computing and machine learning applications.

Management and Security Features

Dell's Integrated management tools, including iDRAC (Integrated Dell Remote Access Controller), are available on both the R750 and R750xs, offering advancement management capabilities for monitoring and maintaining server health and performance. Security features are robust across both models, with options such as Secure Boot, TPM (Trusted Platform Management) and encryption to protect data and infrastructure.
However, the R750 might offer additional advanced security features or configurations, tailored to organizations with high needs of security requirements. These enhancements can include more sophisticated data protection and threat detection capabilities.

Use Case Considerations and Cost

The choice between the R750 and R750xs should be guided by the specific requirements and budget boundaries of the enterprise. The R750xs, with its balanced performance and storage capabilities, is well-suited for a wide array of business applications and can serve as a dependeable high-performance server in most IT environments. The R750, on the other hand, is designed for scenarios where top-tier performance, memory, and storage capacities and speeds are critical. It is the go-to option for enterprises that require the highest level of computational power and storage speed, at a higher cost.


To conclude this post, the Dell PowerEdge R750xs and R750 share a common platform, they are tailored to different operational needs and budget considerations. The R750xs offers a well rounded solution for a variety of business applications, providing a good balance of performance, storage and value. The R750, meanwhile, is optimized for high-demand environments, delivering superior performance, memory, and storage capabilities for those willing to invest in top-tier infrastructure. Understanding the intricate differences between these models is key to making an informed decision that aligns with the startegic IT objectives of any company.
