Dual-Socket 1U Platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. The system targets organisations that need high core counts in a single rack unit.

Included Controller and Network Card

A Dell PERC H730P 2 GB SAS/SATA storage controller provides RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through modes with battery-backed cache. The Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports. iDRAC 9 Enterprise enables full remote management. Two 300 GB 10 K SAS drives, redundant 750 W platinum power supplies, rails and a bezel complete the bundle.

Memory Capacity and Type

The server contains 768 GB of DDR4 2400 MHz registered ECC memory across 24 slots, reaching half of the 3 TB maximum supported by the platform. Buyers who need more memory headroom must populate the remaining DIMM slots with compatible DDR4 modules. This unit does not support other DDR generations.

Questions about this item

How often will the PERC H730P controller battery need replacement?

The PERC H730P includes a battery-backed cache; plan to replace the battery module every three to five years to maintain write-back caching during power loss.

What thermal limit appears first when both Xeon Gold 5118 CPUs run at 3.2 GHz turbo continuously?

The 1U chassis and dual 750 W platinum power supplies set the cooling ceiling; sustained turbo on all 24 cores will hit the thermal design limit before the CPUs throttle.

How loud are the fans and how much power does the server draw under 24/7 load?

Dual 750 W platinum supplies feed the system; fan noise rises to data-centre levels and power draw scales with the 24-core CPU load and 768 GB DDR4 population.
