Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. The system includes 512 GB of DDR4 2400 MHz registered ECC memory across 16 modules. Eight 2.4 TB 10K SAS drives and a PERC H730P controller with 2 GB cache provide high-performance internal storage.

Suited For Scale-Out Workloads

This configuration suits organisations deploying virtualisation clusters, database nodes or high-performance computing tasks that benefit from dual-socket density in a single rack unit. The quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who require more than two processor sockets, GPU acceleration or storage interfaces beyond SAS and SATA should evaluate other platforms.

512 GB DDR4 Registered ECC Memory

The installed 512 GB of DDR4 2400 MHz registered ECC memory occupies 16 of the 24 available DIMM slots, leaving room for expansion up to the 3 TB maximum supported by the Intel C620 chipset. This memory capacity directly determines how many virtual machines, containers or in-memory databases the server can host simultaneously. Verify that your workload fits within this limit or plan for additional modules before deployment.

Questions about this item

Does the server ship with drives and rails, or must I buy 2.5" SAS drives and rails separately?

Eight 2.4TB 10K SAS drives, the PERC H730P controller with battery, ready rails and front bezel are all installed. No extra drives or rails are required.

Should I choose the 512 GB DDR4 configuration or add more memory up to the 3 TB maximum?

Sixteen 32 GB DDR4 2400 MHz ECC modules fill 16 of 24 slots, leaving eight slots open for future expansion to the 3 TB limit.

What does the 2.3 GHz base clock with 3.2 GHz turbo mean for real-world performance on the dual Xeon Gold 5118 CPUs?

Twenty-four cores total run at 2.3 GHz base and can boost to 3.2 GHz under load, delivering high multi-thread throughput for virtualisation and database workloads.
