Design and Build
The Dell PowerEdge R640 follows a standard 1U rackmount design, measuring 28 x 10 x 20 inches, which is typical for dense data center deployments. The “Gold” color noted in the specifications refers to the chassis finish common to Dell’s enterprise hardware. Its build is centered on maximizing compute density within a single rack unit, a crucial factor for businesses with limited physical space. The inclusion of rails facilitates standard 19-inch rack installation. As a renewed product, its physical condition is certified by Amazon Renewed’s quality standards, which aim to ensure it meets functional and cosmetic criteria suitable for professional environments. The design emphasizes serviceability with hot-swappable power supplies, allowing for replacement without system downtime, a critical feature for maintaining uninterrupted operations.
Performance and Features
Processing and Memory
Powered by an Intel Xeon E5-2600 v3 series processor with 32 cores running at a base frequency of 2.10GHz, this server is built for parallel processing and multitasking. Paired with 256GB of DDR4 RAM, it is well-equipped to handle heavy virtualization workloads, database applications, and private cloud implementations. This combination allows for efficient resource optimization and can support a significant number of virtual machines or containers, making it ideal for consolidating server infrastructure.
Storage and Data Protection
The server is listed with a total of 7.7TB of SSD storage, which provides fast data access and high storage density critical for I/O-intensive applications. The storage utilizes a SATA 6 Gb/s interface and is managed by a PERC H730 RAID controller with 12Gb/s throughput and 2GB of NV cache. This controller supports various RAID configurations for data redundancy and performance enhancement, a key feature for data protection in business environments. It is important to note the manufacturer states that hard drives and memory upgrades are included separately and require installation.
Connectivity and Expansion
Network connectivity is handled by a Broadcom BCM5720 Quad Port 1GbE network daughter card (rNDC), providing four Gigabit Ethernet ports for network aggregation, failover, or segmentation. The server has a total of four expansion slots, allowing for the addition of graphics cards, network adapters, or other PCIe devices. Graphics output is supported via KVM over IP through the iDRAC interface or potentially through a dedicated graphics coprocessor listed as “Intel UHD Graphics 630 or equivalent,” which is useful for local console access or GPU-accelerated tasks.
Management and Security
A standout feature for enterprise management is the inclusion of iDRAC9 (Integrated Dell Remote Access Controller) Express. This allows for out-of-band server management, enabling administrators to monitor system health, configure settings, and perform power operations remotely, independent of the server’s operating system. Basic security features are provided through the combination of the iDRAC9 interface and the supported server operating systems like Linux and Windows Server, which offer their own security frameworks and tools.
Setup, Support and Ownership
Potential buyers should be prepared for a hands-on setup process. The product description explicitly notes that hard drives and memory upgrades are included separately and require installation. This implies the end-user must physically install these components, which necessitates technical skill and comfort with server hardware. The server includes power cords, and custom configurations are noted as available upon request, suggesting some level of pre-sales configuration flexibility. As a renewed product, long-term reliability may involve variability, and support would typically be handled through the Amazon Renewed program’s warranty rather than directly from Dell. The availability of spare parts is listed with an “EU Spare Part Availability Duration” of 5 years, though applicability may vary by region.
What Owners Say
There are currently no buyer review excerpts available for this specific ASIN. The product holds a rating, but without detailed user feedback, it is challenging to validate real-world performance, noise levels, power consumption in specific scenarios, or the consistency of the renewal process for this model. Prospective buyers must rely solely on the manufacturer’s specifications and the reputation of the Amazon Renewed program when considering this server, lacking the anecdotal evidence that often highlights practical strengths or recurring issues.

Who Should Buy It (and Who Should Skip It)
The Amazon Renewed Dell PowerEdge R640 is an excellent fit for IT professionals, small business owners with technical staff, or lab environments needing robust hardware for virtualization, private cloud stacks, or as a backend for software-defined storage. Its specifications make it suitable for those looking to consolidate physical servers or run applications like databases, ERP systems, or development platforms that benefit from high core counts and large memory. It also appeals to buyers comfortable with server hardware assembly, as component installation is required.
This server is not ideal for individuals or businesses lacking in-house IT expertise, as the setup process is non-trivial. Those requiring brand-new equipment with full manufacturer warranties and direct vendor support should also look elsewhere. Furthermore, if your workload depends on the latest generation processors, faster than Gigabit network interfaces, or you cannot tolerate any uncertainty regarding hardware history, a new server model might be a more appropriate, though more expensive, choice.

Final Verdict
The Amazon Renewed Dell PowerEdge R640 Server presents a compelling value proposition for the right user. Its core specifications—32 cores, 256GB RAM, and 7.7TB of SSD storage—deliver serious performance capable of handling demanding enterprise workloads like virtualization and private cloud. The inclusion of enterprise features such as iDRAC9 remote management, hot-swappable power supplies, and a PERC RAID controller adds significant operational value, promoting efficiency and reducing potential downtime.
However, the purchase decision hinges on a willingness to engage with renewed hardware and perform the final assembly. The lack of owner reviews adds an element of uncertainty, and the requirement to install drives and memory means this is not a plug-and-play solution. For a technically adept buyer seeking to maximize performance per dollar in a data center or lab setting, this server is a strong candidate. For others, the complexity and renewed nature may be significant drawbacks. As with any significant hardware investment, aligning the product’s capabilities and requirements with your specific needs and technical capacity is essential.

FAQs
What does “Renewed” mean for this Dell PowerEdge server?
“Renewed” indicates the server has been professionally inspected, tested, and cleaned by Amazon or a third-party supplier to meet Amazon Renewed’s functional and cosmetic standards. It is not brand new but is certified to work and look like new. This process aims to ensure reliability, though long-term performance may have more variability than a new unit, and it typically comes with a limited warranty from the renewer rather than the original manufacturer.
Do I need to install the hard drives and memory myself?
Yes. The product description explicitly states that hard drives and memory upgrades are included separately and require installation. The buyer is responsible for physically installing these components into the server chassis. This necessitates a moderate level of technical skill, including handling static-sensitive components and correctly seating them in their respective slots.
What operating systems can I run on this server?
The specifications list the operating system compatibility as “Linux/Windows Server.” This means the server hardware is compatible with various distributions of the Linux operating system and versions of Microsoft Windows Server. You will need to procure and install your chosen operating system license and media separately; no operating system is pre-installed.
What remote management capabilities does it have?
The server includes iDRAC9 Express (Integrated Dell Remote Access Controller). This provides out-of-band management, allowing you to monitor system health, view logs, configure hardware settings (like RAID), and control power (on/off/reboot) remotely over a network connection, independent of whether the server’s main operating system is running or not. This is a crucial tool for administering servers in a data center environment. For more on managing infrastructure, consider reading about cybersecurity fundamentals.
