Dell PowerEdge R640 1U Rack Server – CTO Chassis | Custom Configurable Dual-Socket Xeon Scalable Server
Dell PowerEdge R640 – 1U Dual-Socket CTO Rack Server
Built for Maximum Density, Fully Customizable to Your Needs
The Dell PowerEdge R640 is a 1U rack-server powerhouse designed for dense scale-out data center environments - yet with the flexibility to tailor to your exact workload and budget. As a CTO (Configure-To-Order) chassis, the R640 allows you to choose processors, memory, storage, networking and management options so you build the right infrastructure for virtualization, private cloud, data analytics or HPC.
With support for up to two Intel® Xeon® Scalable processors, up to 24 DDR4 DIMM slots, flexible drive configurations (2.5” or 3.5”, SAS/SATA/NVMe) and multiple I/O options, this server gives you performance, scalability and density in one efficient 1 U footprint.
At Network Outlet, we offer the R640 chassis as a base platform and you tell us your target use-case (virtualization, database, high-throughput, etc.). We’ll quote a fully configured system - including your custom CPU, RAM, storage type & capacity, NICs, RAID controller, power-supply redundancy - so you get exactly what you need, not just off-the-shelf.
Choose your specs, and we’ll build, validate and deliver ready-to-deploy.

FAQs
Q1: What does “CTO chassis” mean in this context?
A1: “CTO” stands for Configure-To-Order. With the R640 chassis, we offer you the base 1U rack unit and you choose the components (CPU, RAM, drives, networking, etc.). We then build the exact system you need and deliver a ready-to-deploy server.
Q2: Can I upgrade later if I start small?
A2: Yes — the R640 architecture supports scaling in memory and storage (and often CPUs) as your demands grow. Because it’s a full dual-socket platform with 24 DIMM slots and flexible drive bays, you can stage your investment.
Q3: Which types of storage drives are supported?
A3: The R640 supports 2.5” or 3.5” SAS/SATA HDD/SSD options, and also NVMe SSDs for high throughput workloads. You choose the drive type and capacity based on your workload (e.g., database I/O vs archival storage).
Q4: What workloads is the R640 best suited for?
A4: It excels in virtualization, cloud infrastructure, dense compute clusters, storage-heavy nodes (with NVMe), and general enterprise data center use where 1U density is beneficial.
Q5: Can I get remote management and monitoring features?
A5: Yes — as with other Dell PowerEdge servers, the R640 supports integrated out-of-band management (e.g., iDRAC) for remote monitoring, updates, and control.
Q6: How do I request a custom configuration / get a quote?
A6: On our Network Outlet website, select this product, fill in your workload requirements (CPU cores, RAM size, drive type/capacity, network bandwidth, redundant power, etc.), and we’ll respond with a tailored quote including build time, shipping and support.
