Dual-Socket 1U Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre deployments. It ships with two Intel Xeon Silver 4110 processors, each running at 2.1 GHz with eight cores. The system includes 64 GB of DDR4 registered ECC memory across four 16 GB modules. Eight 400 GB SATA SSDs and a PERC H730P controller provide internal storage.

Compute Density Focus

This configuration suits organisations that need high core counts and fast flash storage in a single rack unit. The dual Xeon layout and 24 DIMM slots allow memory expansion up to 3 TB for virtualisation or database workloads. Buyers who require more than eight drive bays or a different drive interface should evaluate alternative chassis designs. The included quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ connections.

24 DDR4 Slots for 3 TB Maximum

The motherboard provides 24 DDR4 memory slots with a supported maximum of 3 TB. This single specification determines whether the platform can meet future memory growth without a hardware change. Current population uses only four slots, leaving twenty free for registered ECC modules. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 modes for the installed SATA SSDs.

Questions about this item

How loud and hot does the R640 get with both Xeon Silver 4110 CPUs and eight SSDs running continuously?

The server uses redundant 750 watt platinum power supplies and a 1U chassis designed for data-centre airflow; actual acoustics and thermals depend on rack density and inlet temperature.

Which rails and caddies do I need to mount the R640 and populate its drive bays?

Ready Rails and a front bezel are included; the eight 2.5 inch bays accept SATA SSDs and the PERC H730P controller manages them.

Can I keep using my existing DDR4 registered ECC modules to expand the R640 beyond the installed 64 GB?

The system has 24 DDR4 slots supporting up to 3 TB total; the installed memory is 4 x 16 GB registered ECC at 2400 MHz.
