Dual-Socket 1U Rack Platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data center computing. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. The system includes 768 GB of DDR4 registered ECC memory across 24 slots. Eight 2.4 TB SAS hard drives and a PERC H730P controller provide high-capacity storage.

Tool-Less Rail Installation

The server comes with ready rails and a front bezel for standard rack mounting. Installation is tool-less once the rails are secured to the cabinet. The 1U height allows dense stacking but leaves limited cable routing space behind the chassis. Hot-swap power supplies and drive bays simplify maintenance without downtime. Ensure the rack depth supports the full chassis length before fitting.

Verify Power And Network Needs

Dual 750 watt platinum power supplies require matching PDU connectors and circuit capacity. The Intel X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports; confirm your switch has compatible transceivers. Memory uses DDR4 2400 MHz registered ECC modules only. The PERC H730P supports SAS and SATA drives in RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes.

Questions sur cet article

How can I verify the PERC H730P controller is managing all 8 drives correctly after setup?

Open the PERC H730P BIOS utility or iDRAC9 Enterprise storage view and confirm the virtual disk shows all 8 physical drives in the desired RAID level with optimal status.

What is included with the R640 and what must be purchased separately?

The server ships with 2 Xeon Gold 5118 CPUs, 768GB DDR4, PERC H730P, 8x 2.4TB SAS drives, X520/I350 quad-port NIC, iDRAC9 Enterprise, 2x 750W PSUs, bezel and rails. OS licences, SFP+ modules and extra memory are not included.

Which memory capacity should I choose if I need room to grow beyond 768GB?

The R640 has 24 DDR4 slots and supports up to 3TB; the current 768GB uses 24x 32GB modules, so any increase requires replacing modules with higher-capacity DDR4 DIMMs.
