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.

Questions about this item

How can I verify the PERC H730P controller and all eight 800GB SSDs are recognized after first boot?

Enter the H730P BIOS utility during POST with Ctrl+R; the Virtual Disk Management screen should list a single RAID array containing eight 800GB physical disks and show Optimal status.

Which items are included — bezel, rails, network card, iDRAC licence, power supplies — and what must I source separately?

The shipment includes the 1U chassis, front bezel, sliding Ready Rails, X520/I350 quad-port daughter card, iDRAC9 Enterprise licence, and two 750W platinum hot-swap PSUs; only rack mounting hardware and SFP+ transceivers are not supplied.

With 24 DIMM slots and 768GB already installed, which DDR4 modules should I add to reach the 3TB maximum?

The system holds 24x 32GB RDIMMs today; populate the remaining slots with matching 32GB DDR4-2400 registered ECC modules to scale toward the 3TB limit.
