Dell EMC PowerEdge R640 10-Bay SFF NVMe 1U Rack Server

The Dell EMC PowerEdge R640 is a dual-socket 1U rack server built for production workloads where space is at a premium and performance isn't negotiable. This is a professionally refurbished 14th-generation Dell platform — pulled from real data centers, fully inspected, and rebuilt to spec. Two processor sockets, 24 DDR4 DIMM slots, and up to 10 front-accessible 2.5" SFF drive bays give this platform a lot of headroom for a box that only takes up one rack unit. Worth noting: that combination of density and configurability is not something you find in every 1U chassis.

On the processor side, the R640 supports Intel Xeon Scalable processors (1st and 2nd Generation) — configurable from Silver-class chips through Platinum-tier CPUs depending on what your environment calls for. Storage is where the configuration options get genuinely interesting. The standard chassis handles 10 x 2.5" SAS/SATA bays with support for HDDs and SSDs. When it comes to NVMe, this one gives you options: it can be configured with up to 10 NVMe bays for workloads where storage latency matters in real production, not just on a benchmark. That level of flexibility in a single rack unit is uncommon and worth factoring into the decision.

This is a workhorse platform that thrives in environments like:

• Virtualization hosts running VMware, Hyper-V, or Proxmox — 24 DIMM slots across two sockets means high VM density without sacrificing the footprint efficiency that rack-dense environments require
• Latency-sensitive database workloads where an NVMe-configured build delivers measurable gains in sustained production throughput, not just in controlled testing
• Web, application, and containerized deployments where consistent performance at sustained utilization matters more than headline specs
• Private cloud and software-defined storage environments that need dense, reliable compute without burning through rack real estate
• HPC and analytics clusters where Gold- or Platinum-class processors pay off on core-intensive batch jobs
• Edge and colocation builds where power efficiency and 1U density are hard constraints, not preferences

Redundant power is standard — dual hot-swap power supplies are included, available in 750W Platinum, 750W Titanium, or 1100W configurations depending on the build. Remote management is handled through Dell iDRAC9 with Lifecycle Controller, available in Express or Enterprise tiers, covering out-of-band access, firmware management, and system health monitoring. The R640 also supports an optional TPM 2.0 module for environments with compliance requirements that need hardware-level attestation.

Every R640 at The Server Store has gone through a thorough professional refurbishment process — inspected, tested for full functionality, and configured to your exact specifications before it ships. You're getting enterprise-grade Dell hardware at a significant discount over new pricing, and nothing is given up to get there.
