Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre workloads. It ships with two Intel Xeon Silver 4116 processors, each running at 2.1 GHz with 12 cores. The system includes 512 GB of DDR4 registered ECC memory across 16 modules. Eight 1.2 TB 10K SAS drives and a PERC H730P controller provide high-throughput local storage.

Suited for virtualisation and database clusters

This configuration suits organisations running virtualised workloads, database clusters or high-performance computing tasks that benefit from 24 total cores and large memory capacity. The quad-port 1GbE and 10Gb SFP+ network card supports demanding east-west traffic. Buyers who require GPU acceleration, more than two processors or a different drive interface should evaluate other platforms.

512 GB DDR4 across 24 DIMM slots

The single specification that decides fit is the 512 GB DDR4 memory population using 16 of the 24 available slots. This leaves eight slots open for future expansion up to the 3 TB maximum. Confirm that your application stack and operating system support this memory capacity and the LGA 3647 socket before deployment.

Questions about this item

How long will the PERC H730P controller battery last before it needs replacement?

The PERC H730P includes a 2 GB cache backed by a battery that typically lasts three to five years; plan to replace it when the iDRAC9 Enterprise console reports a degraded or failed battery status.

What component reaches its thermal limit first when the dual Xeon Silver 4116 processors run at 3.0 GHz turbo continuously?

The CPU package temperature will hit its throttle point before the 750 W platinum power supplies or the 10 K SAS drives, so sustained turbo clocks depend on the 1U chassis airflow and fan curves.

How loud are the fans when the server runs a full load all day with both CPUs and eight drives active?

The 1U form factor uses high-RPM fans that become noticeably loud under sustained load; expect data-centre noise levels rather than office-quiet operation.
