DELL PowerEdge R640 1U Rack Server 2x Xeon Silver 4110 2.1GHz 8-Core 768GB DDR4 8x 800GB SSD H730P

Dual-socket 1U rack server

The Dell PowerEdge R640 is a dual-socket 1U rack server built for dense scale-out data center computing. It ships with two Intel Xeon Silver 4110 2.1 GHz 8-core processors, 768 GB of DDR4 registered ECC memory across 24 slots, and a PERC H730P 2 GB storage controller. Eight 800 GB SATA SSDs fill the 2.5-inch drive bays, while an Intel X520/I350 quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections. iDRAC 9 Enterprise and redundant 750 W platinum power supplies complete the platform.

Installation and common issues

The 1U chassis mounts in a standard rack using the included Ready Rails, and the hot-swap drive bays allow SSD installation without tools. The PERC H730P controller battery must be seated correctly for RAID write-back caching to function. Memory population follows specific channel rules across the 24 DDR4 slots; incorrect placement can prevent boot or reduce performance. Network daughter card seating should be verified if SFP+ links fail to negotiate.

Pre-order compatibility checks

Confirm the rack provides 1U of vertical space and adequate front-to-back airflow for the redundant power supplies. Verify that your infrastructure supports SFP+ transceivers for the 10 Gb ports and that cabling reaches the rear I/O panel. Ensure the operating system and hypervisor versions in your environment include drivers for the PERC H730P controller and Intel X520/I350 network adapters. Check that the available power circuits can deliver the required current for dual 750 W supplies.
