Dense 1U compute platform

The Dell PowerEdge R640 is a 1U rack server built for scale-out data centre workloads. It ships with two Intel Xeon Silver 4110 8-core processors running at 2.10 GHz with 3.0 GHz turbo. The system includes 128 GB of DDR4 2400 MHz registered ECC memory across eight 16 GB modules. Eight 1.2 TB 10K SAS drives connect through a PERC H730P 2 GB controller with battery-backed cache.

Virtualisation hosts and database nodes

This configuration suits buyers who need high core density and fast local storage in a single rack unit. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ links for flexible connectivity. iDRAC 9 Enterprise enables full remote management. Buyers who require more than 24 DIMM slots, additional drive bays beyond the eight 2.5 inch bays, or GPU acceleration should consider alternative platforms.

24 DDR4 slots define memory ceiling

The server populates eight of 24 DDR4 slots, leaving 16 slots open for future expansion up to the 3 TB maximum. All installed memory is registered ECC DDR4 2400 MHz. The LGA 3647 socket and Intel C620 chipset limit processor upgrades to the same Scalable family. Buyers planning large memory footprints must verify module compatibility before purchasing additional DIMMs.

Questions about this item

Will the eight 1.2 TB SAS drives and the H730P controller work with the SAS backplane in my existing rack?

The R640 uses an eight-bay 2.5-inch SAS backplane wired to the PERC H730P 12 Gb/s controller, so the installed drives connect directly without an adapter.

How can I confirm the dual Xeon Silver 4110 CPUs and 128 GB DDR4 are recognised after first boot?

Open the iDRAC 9 Enterprise web interface or press F2 at POST; the System Overview page shows two 8-core processors at 2.1 GHz and 128 GB of registered ECC DDR4.

Which items ship in the box and what must I source separately?

The server arrives with bezel, ready rails, two 750 W platinum PSUs, the X520/I350 quad-port network card, H730P controller with battery, eight 1.2 TB SAS drives and 128 GB DDR4; only SFP+ transceivers and an operating system licence are not included.
