Dual-Socket 1U Server Platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out deployments. It ships with two Intel Xeon Gold 6148 processors, each delivering 20 cores at 2.4 GHz with 3.7 GHz turbo. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules and dual 750 W platinum power supplies for redundancy.

Compute-Dense Workloads vs. Expansion Needs

This configuration suits virtualisation clusters, database nodes and high-performance computing tasks that benefit from 40 total cores and large memory capacity in a single rack unit. The eight-bay 2.5-inch chassis filled with 2.4 TB SAS drives leaves no room for additional internal storage, so buyers who need more drive bays must look elsewhere.

PERC H730P RAID Controller Decides Fit

The installed Dell PERC H730P 2 GB controller provides 12 Gb/s SAS and SATA connectivity with hardware RAID levels 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Confirm this controller matches your storage topology and RAID requirements before purchase.

Questions sur cet article

How many CPU cores does the dual Xeon Gold 6148 configuration provide for sustained workloads?

The two Xeon Gold 6148 processors deliver 20 cores each, giving 40 cores total at 2.4 GHz base with 3.7 GHz turbo for heavy sustained compute.

What is the power draw of the redundant supplies when the server runs continuously?

Dual 750 Watt platinum-efficiency power supplies share the load, providing redundancy while keeping heat and fan noise lower under all-day operation.

Which memory modules must already be on hand to expand the 256 GB DDR4 installation?

The system uses DDR4 2666 MHz registered ECC DIMMs; 24 slots are available and 8 are populated with 32 GB modules, so matching DDR4 RDIMMs are required for expansion.
