Overview

Reliable Performance for Demanding Workloads

The Dell PowerEdge R640 server offers a powerful and scalable solution for various business applications. Equipped with an Intel Silver 4110 Eight Core processor, 128GB of RAM, and an H730 controller, this server delivers reliable performance and efficient data management in a compact 1U form factor.

Specifications:

  • Processor: Silver 4110 Eight Core 2.1Ghz
  • Memory: 128GB RAM
  • Drive Bays: 8 x 2.5 Hot Plug
  • Controller: H730
  • Condition: Renewed

Pros & Cons

👍 Pros

  • 128GB DDR4 ECC RDIMM delivers substantial memory headroom for virtualization hosts — sufficient to run 20–40 light VMs depending on per-VM allocation — while ECC protection ensures data integrity under continuous operation.
  • Eight 2.5-inch hot-plug bays allow drive replacement without downtime, a baseline requirement for any production storage configuration.
  • H730 PERC controller with 1GB NV cache supports RAID 5/6/10 and write-back caching, providing both redundancy and a measurable write performance improvement over software RAID.
  • 1U form factor maximizes rack density — the R640 occupies half the vertical space of a 2U chassis, critical in constrained datacenter or colocation environments.
  • Dual-socket capable design allows a second Xeon Silver 4110 to be added post-purchase, doubling CPU throughput without replacing the platform.

👎 Cons

  • Silver 4110's 2.1 GHz base clock is low by modern standards; workloads sensitive to single-threaded performance — certain legacy enterprise applications, some database query patterns — will be constrained by the 3.0 GHz Turbo ceiling.
  • "Renewed" status means drive population is unspecified in the listing; buyers should not assume drives are included and must account for storage acquisition costs separately.
  • 8 x 2.5-inch bays cap raw storage capacity at roughly 16TB with 2TB SAS drives — insufficient for high-density storage workloads without an external shelf.
  • No GPU slot utility — the R640's 1U chassis restricts PCIe expansion, limiting this platform to compute and storage roles rather than GPU-accelerated inference or rendering.
  • iDRAC Enterprise license status on renewed units is often unverified; remote management capabilities may require license purchase to fully enable.

Frequently Asked Questions

The Intel Xeon Silver 4110 runs 8 cores and 16 threads at 2.1 GHz base (up to 3.0 GHz Turbo). It is well-suited for virtualization hosts (running 8–20 light VMs depending on RAM allocation), database servers, ERP applications, and CI/CD build infrastructure. Sustained single-threaded performance is modest — workloads requiring high per-core clock speed will see a ceiling at 3.0 GHz Turbo.
Yes. The PowerEdge R640 uses DDR4 RDIMM ECC memory. ECC (Error-Correcting Code) memory automatically detects and corrects single-bit memory errors in real time, which is essential for long-running server workloads where uncorrected memory errors can cause data corruption or silent failures. This is a hard requirement for production database and virtualization environments.
The Dell PERC H730 supports RAID 0, 1, 5, 6, 10, 50, and 60 across the eight 2.5-inch hot-plug bays. It includes a 1GB non-volatile cache with battery backup, which enables write-back caching — a meaningful performance advantage for database write operations compared to write-through configurations.
"Renewed" means the unit has been refurbished — typically cleaned, tested, and recertified, with failed components replaced. Buyers should confirm what warranty is included, whether iDRAC enterprise license is activated, and verify drive bay population and installed RAM configuration upon receipt, as renewed units sometimes ship with configurations that differ from the listing.
The R640 supports dual Intel Scalable processors. A second Silver 4110 can be added to the empty CPU socket, doubling the core count to 16 cores / 32 threads and expanding total memory capacity. Both CPUs must be the same Xeon Scalable family and stepping for dual-socket operation.
