Dell PowerEdge R640 is a dense 1U, dual-socket rack server for dense virtualization, database, web, software-defined storage and scale-out data center workloads. It is designed for environments that need a careful balance of compute performance, memory capacity, storage flexibility, management features and long-term serviceability.
The R640 server is based on up to two 2nd Generation Intel Xeon Scalable processors. It supports 24 DDR4 RDIMM/LRDIMM slots, up to 3 TB, speeds up to 2933 MT/s, with NVDIMM-N and Intel Optane DC Persistent Memory support in selected configurations, Dell iDRAC management through iDRAC9, network daughter card options including 1GbE, 10GbE and 25GbE choices, up to 3 PCIe Gen3 x16 slots and up to 10 x 2.5-inch SAS/SATA/NVMe drives, up to 10 NVMe drives, or up to 4 x 3.5-inch SAS/SATA drives, with optional rear 2SFF drives.
Dell PowerEdge R640 is suitable for the workload categories listed below and should be treated as a dense 1U performance platform, not a storage-heavy 2U server. Compared with newer or larger Dell PowerEdge platforms, this model should be selected when its generation, form factor, storage layout and cost profile match the project.
When to choose Dell PowerEdge R640
Choose Dell PowerEdge R640 when the workload needs dense 1U, dual-socket rack server characteristics, predictable local storage and Dell PowerEdge management. It is a good fit for dense virtualization, database, web, software-defined storage and scale-out data center workloads.
Compared with smaller or entry platforms, Dell PowerEdge R640 provides more appropriate headroom for its target role. Compared with larger or newer PowerEdge systems, it should be selected when acquisition cost, compatibility with existing infrastructure and the exact drive layout are more important than the latest platform generation.
The R640 configuration should be validated carefully for processor count, memory population, drive bay layout, storage controller, boot device, risers, network adapters, power supplies, fans and cooling. This is especially important for NVMe, rear-drive, GPU, redundant power and mixed-drive configurations.
Chassis and drive bay options
Dell PowerEdge R640 supports the following practical chassis, drive and configuration options. The right choice depends on whether the server is being configured for capacity, SSD responsiveness, NVMe performance, boot separation, redundant power or accelerator support.
| Chassis option | Best for | Comment |
|---|---|---|
| Dell PowerEdge R640 8SFF | 2.5-inch SSD/HDD density, serviceability and business applications | Use this option when 2.5-inch density, SSD responsiveness and serviceability are more important than 3.5-inch HDD capacity. Supports up to 8 x 2.5-inch SAS/SATA/NVMe drives in selected configurations. |
| Dell PowerEdge R640 10SFF | SSD responsiveness, NVMe performance and latency-sensitive workloads | Use this option when low-latency SSD or NVMe performance is required. Supports up to 10 x 2.5-inch drives, including up to 10 NVMe drives or mixed SAS/SATA/NVMe layouts; confirm backplane, controller, cabling and thermal rules. |
| Dell PowerEdge R640 12SFF | 2.5-inch SSD/HDD density, serviceability and business applications | Use this option when 2.5-inch density, SSD responsiveness and serviceability are more important than 3.5-inch HDD capacity. Supports front and rear SFF layout for selected dense drive configurations. |
| Dell PowerEdge R640 BOSS / rear drive options | separating OS or hypervisor boot from data drives | Use this option to keep OS or hypervisor boot separate from the main front drives. Supports BOSS hardware RAID with 2 x M.2 SSDs and optional rear 2 x 2.5-inch drive support; confirm OS and controller support before ordering. |
| Dell PowerEdge R640 GPU / FPGA options | validated accelerator, VDI or GPU-enabled workloads | Use only validated accelerator combinations. Supports up to 3 single-width NVIDIA T4 GPUs or up to 1 FPGA, depending on riser and thermal configuration; check risers, power cables, fans and thermal limits. |
For capacity workloads, LFF configurations are usually the practical starting point. For latency-sensitive databases, virtualization datastores and high-IO workloads, SFF SSD or NVMe-capable configurations should be considered where the platform supports them.
Final drive compatibility depends on the selected chassis, backplane, controller, cables, risers, cooling configuration and Dell support matrix. Do not assume that every drive type, controller and rear-drive option can be combined in one configuration.
Recommended Dell PowerEdge R640 configurations by workload
| Workload | Recommended focus |
|---|---|
| Virtualization / private cloud | Balanced CPU count, large memory pool, SSD or NVMe storage where supported, redundant networking and validated boot media. |
| Databases / data management | Processor choice matched to licensing and query profile, enough RAM for cache, low-latency SSD or NVMe storage and protected arrays. |
| Containers / Kubernetes | Balanced CPU and RAM, reliable boot device, fast local SSD when needed and redundant network connectivity for cluster traffic. |
| Software-defined storage / HCI | Drive layout, HBA/JBOD or controller mode, network bandwidth and CPU/RAM sized for the selected SDS or HCI platform. |
| VDI | High RAM density, predictable CPU performance, fast storage and validated GPU options when graphics acceleration is required. |
| Web and application services | Balanced CPU, enough memory, SSD-backed local storage and network options sized for application traffic. |
| GPU-accelerated workloads | Validated GPU or FPGA model, risers, power cables, cooling limits and memory sizing checked before purchase. |
| Mixed enterprise workloads | Balanced CPU, RAM, storage and NIC choices, with headroom for failover, maintenance and growth. |
The R640 configuration should be chosen around the main reason for selecting this platform: a dense 1U performance platform, not a storage-heavy 2U server, 24 DDR4 DIMM slots / up to 3 TB plus selected NVDIMM or PMem options, 8SFF, 10SFF, 12SFF/NVMe or 4LFF layouts depending on chassis, Dell iDRAC9 management and a validated power, cooling and controller design.
How to choose CPU, RAM, RAID and storage
Dell PowerEdge R640 supports up to two 2nd Generation Intel Xeon Scalable processors. CPU choice should be tied to workload profile, software licensing and thermal limits. up to 28 cores per processor help when virtualization, databases or multi-user services need more parallelism, while higher clock speed can matter for applications sensitive to per-core performance.
RAM planning should start with VM density, database cache requirements, application growth and backup or monitoring agents. Dell PowerEdge R640 supports 24 DDR4 RDIMM/LRDIMM slots, up to 3 TB, speeds up to 2933 MT/s, with NVDIMM-N and Intel Optane DC Persistent Memory support in selected configurations. Memory speed and maximum capacity depend on processor choice and DIMM population, so the final layout should be validated before ordering.
For storage, use 8SFF, 10SFF, 12SFF/NVMe or 4LFF layouts depending on chassis when it matches the workload. up to 10 x 2.5-inch SAS/SATA/NVMe drives, up to 10 NVMe drives, or up to 4 x 3.5-inch SAS/SATA drives, with optional rear 2SFF drives. Boot devices such as BOSS or internal M.2 options can separate OS or hypervisor boot from the main data drives where supported.
RAID and HBA choice should be made before finalizing drive count. PERC H330, H730P, H740P, HBA330, H840, 12Gbps SAS HBA, S140 and BOSS M.2 boot. Hardware RAID is appropriate for classic protected arrays, while HBA/JBOD or software RAID may be better for selected software-defined storage designs.
Network, GPU and power choices should also be checked as a single configuration. Dell PowerEdge R640 includes or supports network daughter card options including 1GbE, 10GbE and 25GbE choices, up to 3 PCIe Gen3 x16 slots, up to 3 single-width NVIDIA T4 GPUs or up to 1 FPGA in supported configurations, and 495W, 750W, 1100W and 1600W hot-plug redundant power supplies, with selected DC/HVDC options. Validate risers, airflow and power supply redundancy before purchase.
