About This Product
Overview
The Dell PowerEdge R640 is a rack server designed for environments that need strong processing capability in a compact 1U form factor. Built on the PowerEdge platform, this configuration combines dual Intel Xeon Gold 6138 processors with ECC RDIMM memory and enterprise SAS storage, making it a practical choice for virtualization, application hosting, and general business server workloads. The 8 SFF barebone chassis provides a flexible foundation for data center deployments where space efficiency and serviceability matter. With redundant power supplies and a hardware RAID controller included, this server is structured to support dependable operation in a rack-mounted setup. For buyers looking for a Dell rack server with balanced compute, storage, and expansion potential, the R640 remains a versatile option.
Performance & Scalability
This system is equipped with two Intel Xeon Gold 6138 processors, giving it a total of 40 cores and 80 threads for multi-threaded workloads and concurrent user environments. That level of CPU capacity is well suited to tasks that benefit from parallel processing, including virtualization hosts, database services, and internal business applications. The installed DDR4-2400 ECC RDIMM memory supports server-grade reliability and helps maintain stable performance under continuous use. Because the R640 is a rack server platform, it is designed to fit into standard infrastructure while still offering the processing density many organizations need. The included H730 RAID controller adds another layer of manageability for storage arrays, helping administrators configure drives for performance or data protection based on their environment.
Storage Flexibility
This Dell PowerEdge R640 includes an 8 SFF barebone chassis and enterprise SAS drives, giving it a storage setup suited to business workloads that require consistent access to data. The 2.5-inch SAS drive format is commonly used in server environments for dependable performance and compatibility with enterprise storage configurations. With the H730 RAID controller in place, the system can be organized to support a range of storage strategies depending on operational needs. The compact chassis design also helps maximize rack density while still allowing room for a practical drive-based configuration. For organizations that want a rack server with established Dell storage architecture and room to adapt to changing requirements, this platform offers a solid starting point.
Why Choose This Product?
The Dell PowerEdge R640 is a strong fit for buyers who want a proven rack server platform with enterprise features already in place. Dual Xeon Gold processors, ECC memory, SAS storage, RAID support, and redundant power supplies combine to create a well-rounded system for business IT environments. Its 1U design helps conserve rack space without sacrificing core server capabilities, which can be especially valuable in growing infrastructure deployments. As a Dell server, it also benefits from a widely recognized hardware ecosystem and a configuration that is easy to understand for IT teams managing rack-based systems. If you need a server that balances compute power, storage readiness, and operational reliability, this R640 configuration is a practical choice.
About this server
Dell PowerEdge R640 8 SFF with two Xeon Gold 6138 20 core CPUs, 24GB DDR4-2400 ECC, 2.4TB 10K SAS, H730 and dual 750W PSUs. Tested and stocked in Doha, delivered across Qatar within a day.
ServerDove assembled this refurbished R640 in Doha on the 8 SFF barebone. It has two Intel Xeon Gold 6138 processors, each 20 cores and 40 threads at 2.0GHz, six Micron 4GB DDR4-2400 ECC RDIMMs for 24GB, two Dell 1.2TB 10K SAS 12Gb/s 2.5 inch enterprise hard drives on an H730 RAID controller, and two 750W redundant power supplies.
The build pairs a great deal of processor with a small, fast memory set, populating three channels on each CPU so bandwidth is balanced across the sockets. It suits a buyer in Qatar who needs a 40 core 1U node with redundant power now and will size the memory to the workload later, which the R640's 24 DIMM slots make straightforward.

Configuration
Installed parts, with module counts known for this assembly.
| Barebone | Dell PowerEdge R640 8 SFF, 1U rack, 14th generation |
| CPU | 2 x Intel Xeon Gold 6138, 20C 40T, 2.0GHz |
| RAM | 6 x Micron 4GB DDR4-2400 ECC RDIMM, 24GB |
| Storage | 2 x Dell 1.2TB 10K SAS 12Gb/s 2.5 inch enterprise HDD, 2.4TB |
| RAID | H730 controller |
| PSU | 2 x 750W redundant |
What this configuration suits
Processor bound work that does not need much memory per core: build farms, batch jobs, rendering, containerised services. For virtualisation, 24GB is a starting point, and adding memory is the obvious next step; the processors are already more than most estates need.
The mirrored 10K SAS pair on the cached H730 is a dependable system volume. Six open bays take SSDs for data.
Upgrade paths
- Memory: 18 free DIMM slots; the Gold 6138 runs 2666 MT/s, but new modules mixed with the fitted 2400 modules will run at 2400
- Storage: six empty SFF bays, ready for SSDs or more SAS drives on 14th generation caddies
- Network: the PCIe 3.0 risers take 10 GbE or 25 GbE cards
- Management: an iDRAC9 Enterprise licence enables the remote console
