Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack-mount server system delivered in new condition. It ships with one Intel Xeon Platinum 8160 processor running at 2.1GHz with 24 cores and 33 MB cache. The chassis provides four 3.5-inch drive bays and includes 256GB of DDR4 ECC registered memory installed as sixteen 16GB modules.

Suited for virtualisation hosts needing large

This configuration suits environments that prioritise memory capacity and dual-processor upgrade potential over maximum drive count. The single CPU leaves a second socket available for future expansion to two processors. Buyers who need more than four 3.5-inch drive bays or require a fully populated dual-CPU configuration from day one should consider alternative platforms.

PERC H740P RAID controller with SATA interface

The installed Dell PERC H740P RAID controller manages storage through a SATA interface. No hard drives are included, so the buyer must supply compatible 3.5-inch SATA drives to populate the four available bays. This controller choice determines the RAID levels and drive types supported for the initial deployment.

Questions about this item

Will the 256 GB DDR4 memory need to be replaced to reach the 7.68 TB maximum?

The system holds 256 GB DDR4 now and supports up to 7.68 TB, so additional DDR4 modules can be added without removing the existing memory.

Which component limits sustained throughput first — the PERC H740P controller or the 10 GbE 562T adapter?

The PERC H740P RAID controller manages the 3.5" SATA drive bays, while the 10 GbE 562T adapter handles network traffic; the first bottleneck depends on whether storage or network workload is heavier.

How much heat and noise do the two 750 W power supplies produce when the server runs all day?

Dual 750 W supplies share the load, and the 1U R640 chassis uses high-speed fans that increase airflow under sustained CPU and RAID controller activity.
