Dense Dual-Socket 1U Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Silver 4110 processors running at 2.1 GHz, each providing eight cores. The system includes 512 GB of DDR4 registered ECC memory across sixteen 32 GB modules. A PERC H730P controller with 2 GB cache manages storage.

Suits Virtualisation and Database Nodes

This configuration suits teams deploying virtualisation clusters, database nodes or high-throughput applications that benefit from dual-socket performance in a single rack unit. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who need more internal drive bays or GPU acceleration should evaluate larger chassis options.

24 DIMM Slots Define Memory Ceiling

The motherboard provides 24 DDR4 slots with a maximum supported capacity of 3 TB, so the installed 512 GB leaves substantial headroom for future expansion. All slots are populated with 32 GB modules in this build, meaning any upgrade requires replacing existing DIMMs. Verify your workload's memory trajectory before committing to this density.

Questions about this item

How can I verify the H730P controller battery is healthy after installation?

Check the iDRAC9 Enterprise interface for battery status and run the PERC H730P BIOS utility to confirm battery health and RAID functionality.

What drives, rails and bezel are included versus what must be purchased separately?

The unit includes 2x 800GB SATA SSDs, Ready Rails and front bezel; additional 2.5" drives for the remaining 6 bays must be purchased separately.

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

The 512GB (16x 32GB DDR4 2400MHz) fills 16 of 24 slots; choose this for current workloads or add modules later for virtualization density up to 3TB.
