The Dell EMC PowerEdge R640xd is a dual-socket 1U rack server built around a chassis configuration that stands out from the standard R640 lineup. This is a professionally refurbished 14th-generation Dell platform — pulled from real production environments, fully inspected, and rebuilt to spec. What makes this particular build different is the bay count: 10 front-accessible 2.5" SFF drive bays plus 2 additional rear flex bays, giving you 12 total SAS/SATA drive positions in a single rack unit. For environments where storage density inside a 1U matters, that distinction is worth paying attention to.
On the processor side, the R640xd supports Intel Xeon Scalable processors (1st and 2nd Generation) — configurable from Silver-class CPUs through Platinum-tier, up to 28 cores per socket and 56 cores total in a dual-processor build. Memory scales across 24 DDR4 DIMM slots, with configurations available up to 3TB of registered ECC RAM. Storage controller options run from the HBA330 for pass-through non-RAID setups through the PERC H330, H730, H730p, and H740p with 8GB battery-backed cache — so the right RAID posture for your workload is covered regardless of which direction that is.
This is a workhorse platform that thrives in environments like:
- Virtualization hosts running VMware, Hyper-V, or KVM where 24 DIMM slots across two sockets translates directly into higher VM density per rack unit
- Software-defined storage deployments, including Dell EMC VxFlex Ready Node configurations, where the 12-bay capacity makes a meaningful difference in usable storage per 1U
- Database and analytics workloads that benefit from high memory capacity — up to 3TB DDR4 — particularly in-memory database engines where RAM availability directly affects performance
- Private cloud infrastructure where reliable, dense dual-socket compute is the baseline requirement and rack space is a real constraint
- HPC clusters where the flexibility to configure Silver through Platinum processors lets the build match the core-count needs of the job
- Edge and colocation builds where 1U density, power efficiency, and storage capacity need to land in the same chassis
Redundant power comes standard — dual hot-swap power supplies are included, 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, providing out-of-band access, firmware management, and system health monitoring. The system is also IPMI 2.0 compliant and supports an optional TPM 2.0 module for environments with hardware security or compliance requirements that aren't optional.
Every R640xd we ship has gone through a complete professional refurbishment process — tested, inspected, and configured to your specifications before it leaves. You're getting enterprise-grade Dell hardware at a significant discount over new pricing, and the 12-bay drive capacity is included at that price.
