Comparing Dell PowerEdge R650 and R650xs Servers

Dell PowerEdge R650 vs R650xs Servers

In the world of enterprise computing, the Dell PowerEdge server line is a well known and respected solution, offering a range of models tailored to various business needs. Among these, the Dell PowerEdge R650 and R650xs stand out for their performance, scalability, and features. While they share similar lineage, key differences set them apart, catering to different user requirements. In this post, we dive into the distinct aspects between the Dell PowerEdge R650 and R650xs, helping businesses make informed decisions for their IT infrastructure.

Performance and Scalability

The Dell PowerEdge R650 and R650xs are both part of the Dell's 15th generation of servers, designed to handle demanding workloads with efficiency and speed. Both models are equipped with the latest Intel Xeon Scalable CPUs, offering a significant performance improvement over previous generations. However, the R650 typically provides more options for higher core counts than the R650xs, which can be critical for compute-intensive applications due to their internal hardware architecture.
In terms of memory, both servers support DDR4 memory technology, and have similar number of DIMM slots, allowing for extensive memory capacity and speed. The R650, however, might offer configurations with higher max memory capacity or faster memory speeds over the R650xs, which is a critical factor for compute-intensive applications.

Storage and Expandability

Storage is another critical aspect where the R650 and R650xs differ. The PowerEdge R650 is generally considered a versatile server with a good balance of storage capacity and performance, suitable for a wide range of applications in the mid-range of high-performance computation. It typically supports various types of drives, including SAS, SATA and NVMe drives, allowing for a flexible storage configuration.
On the other hand the R650xs if often tailored for storage intensive applications, featuring more drive bays and support for additional NVMe drives. Making it an ideal choice for scenarios requiring high-speed storage, such as real-time data analytics or high-performance computing environments (HPC).

Network and Connectivity

Networking capabilities are crucial for modern servers, and both the R650 and R650xs excel in this area. However, the R650xs may offer enhanced networking options and additional network interface card (NIC) slots, providing greater bandwidth and lower latency connections. This is a particularly beneficial for applications that rely heavily on network performance, such as virtualization and cloud services.

Management and Security

Dell's integrated Dell Remote Access (iDRAC) is a cornerstone of PowerEdge server management, offering comprehensive hardware management tools. Both the R650 and R650xs come with advanced iDRAC versions, enabling efficient remote management, maintenance, and monitoring of servers.
In terms of security, both the R650 and R650xs are equipped with Dell's robust security features, including Secure Boot, TPM (Trusted Platform Module), and Secure Erase. However, the R650xs may include additional security enhancements or options, providing an extra layer of protection against cyber threats.

Use Case and Cost

Choosing between the R650 and R650xs often comes down to specific use cases and budget considerations. The R650xs is a well-rounded server, suitable for a broad range of applications from virtualization to medium scale databases. It offers a balance of performance, storage and cost-effectiveness, as it can take up to maximum of 32 Core CPUs.
On the other hand, the R650 is tailored for more specialized or demanding environments, such as high-performance computing or large scale virtualization, where maximum performance and storage are paramount, as the R650 in contrast with the R650xs, can take up to 64 Core CPUs. Naturally, these enhancements may come with a higher price tag, making the R650 more suitable for organizations with specific high-end needs.


In summary, while the Dell PowerEdge R650 and R650xs share many similarities as part of the same server line-up, they cater to different market segments. The R650xs offers a balanced feature set for a wide array of applications, making it a versatile choice for many businesses. Meanwhile the R650 is geared towards high performance environments, justifying its position as a premium offering in the Dell PowerEdge server line. Understanding these differences is key to selecting the right server that aligns with a business's specific needs and budget constraints.
