Dual-socket 1U rack server for dense compute

The Dell PowerEdge R640 packs two Intel Xeon Silver 4110 2.1 GHz 8-core processors into a 1U chassis with 64 GB of DDR4 ECC memory and redundant 750 W platinum power supplies, making it a compact platform for scale-out workloads.

Suited for virtualisation clusters.

This configuration fits virtualisation hosts, hyper-converged nodes or database clusters that benefit from dual-socket density and redundant power. Buyers needing GPU acceleration or expansion beyond the internal drive bays should evaluate larger form-factor systems.

PERC H730P controller

The integrated Dell PERC H730P 2 GB controller supports RAID 0, 1, 5, 6, 10, 50 and 60 across the eight installed 2.5-inch 300 GB 10 000 RPM SAS drives, delivering hardware-accelerated redundancy and performance for local storage.

Questions about this item

How loud and hot does the R640 get with both Xeon Silver 4110 CPUs and eight 300 GB SAS drives running 24/7?

The server uses redundant 750 W platinum power supplies and Dell's thermal design for 1U density; actual acoustic and thermal output depend on workload and rack airflow.

What cabling and transceivers do I need to use the X520/I350 daughter card's 10 GbE SFP+ ports?

The card provides two SFP+ cages for 10 GbE connections; you must supply compatible SFP+ transceivers and fibre or direct-attach cables.

Can I add more DDR4 memory later without replacing the existing 64 GB kit?

Yes, the system has 24 DIMM slots and supports up to 3 TB; the current 4×16 GB configuration leaves 20 slots free for registered ECC DDR4-2400 modules.
