PowerEdge R640 4LFF dual Xeon server

The Dell PowerEdge R640 is a 1U rack server populated with two Xeon Silver 4116 processors at 2.1GHz and 384GB of DDR4 ECC registered memory. It ships without drives but includes a PERC H740P RAID controller and a 10GbE 562T dual‑port adapter for high‑throughput networking. Remote management is handled by iDRAC9 Enterprise and dual 750W supplies provide redundancy.

Ideal for virtualisation and database nodes

This configuration suits teams running memory‑intensive workloads such as virtualisation clusters, in‑memory databases or enterprise applications that benefit from 24 total cores and a large DDR4 footprint. Buyers who need more than four 3.5‑inch drive bays, dedicated GPU compute or a different drive interface should consider other platforms.

Four 3.5‑inch bays with PERC H740P

The chassis provides exactly four 3.5‑inch hot‑plug bays backed by the PERC H740P controller, so storage capacity and RAID level are determined by the drives you install. Maximum supported memory reaches 7.68TB across 24 DIMM slots for future expansion.

Perguntas sobre este artigo

How do I install the 2.1GHz Xeon Silver 4116 processors and what step is often missed?

Seat both CPUs in the sockets, apply thermal paste evenly, and torque the heatsink screws in a cross pattern; the step most often missed is updating the iDRAC9 firmware before first boot so the new microcode loads correctly.

What maintenance will the PERC H740P RAID controller and 750W power supplies need later?

Check the PERC H740P battery backup unit every 12 months and replace it if the charge cycle count exceeds the threshold; clean the 750W PSU air intakes quarterly and swap any unit that shows fan-speed errors in iDRAC9.

What limit appears first when the 384GB DDR4 memory runs sustained workloads?

The 2.1GHz Xeon Silver 4116 memory controllers hit their maximum sustainable bandwidth before the 384GB DDR4 capacity is exhausted, so throughput plateaus while DIMM slots remain free.
