Dual-Socket 1U Compute Platform

The Dell PowerEdge R640 is a dual-socket 1U rack server built for dense scale-out workloads. Two Xeon Gold 6148 processors deliver 40 total cores at 2.4 GHz with 3.7 GHz turbo. The system ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots. It targets organisations that need high core-count density in a single rack unit.

Redundant Platinum Power and Thermal Design

Redundant hot-swap 750 W platinum-efficiency power supplies feed both processors, memory and storage while maintaining uptime during a module failure. The 1U chassis uses forced-air cooling calibrated for the installed 20-core CPUs and dual SSDs. Power draw scales with workload, and the platinum-rated units minimise losses at typical utilisation levels.

Eight-Bay Front Storage with Hardware RAID

Eight 2.5-inch front bays accept SATA or SAS drives; two 400 GB SATA SSDs are installed. The PERC H730P 2 GB controller provides hardware RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ links. iDRAC 9 Enterprise enables remote firmware updates, power control and console access without an operating system. Ready rails and a front bezel are included for immediate rack mounting.

Preguntas sobre este artículo

How do I install the 24 DDR4 32GB modules and what step is often missed?

Populate all 24 slots with registered ECC DDR4 2666MHz modules; the step often missed is enabling the memory training sequence in BIOS after the first boot.

When will the PERC H730P controller battery need replacement?

The 2GB cache battery on the H730P typically lasts 3 to 5 years; replace it when iDRAC9 reports a battery degradation alert.

What thermal limit appears first when both Xeon Gold 6148 CPUs run at 3.7GHz turbo under sustained load?

The 750W platinum power supplies hit their current limit before the CPU thermal throttle activates.
