Dense 1U Dual-Socket 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 2.30 GHz with 12 cores and a 3.2 GHz turbo frequency. The system includes 64 GB of DDR4 2400 MHz registered ECC memory across four 16 GB modules. It is designed for organisations that need high core counts in a single rack unit.

Redundant 750 W Platinum Power

Two hot-swap 750 W platinum-efficiency power supplies provide redundant power for the dual-processor configuration and eight drive bays. The 1U chassis uses forced-air cooling tuned for the installed components. Acoustic output and thermal margins are managed by the integrated iDRAC 9 Enterprise controller, which monitors system health and adjusts fan speeds dynamically during normal operation.

Eight-Bay SAS Storage with 10 GbE

The front panel holds eight 2.5-inch bays populated with 1.2 TB 10K SAS drives connected to a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ links for high-throughput connectivity. Twenty-four DIMM slots allow memory expansion up to 3 TB, while the LGA 3647 sockets are already fully populated with the maximum two processors. Ready Rails and a front bezel are included for immediate rack installation.

Questions about this item

How do I install the Dell PERC H730P controller and its 2GB cache battery in the R640?

The PERC H730P controller and its 2GB cache battery are pre-installed; mount the included Ready Rails into a standard 1U rack space, slide the chassis in until it locks, then secure the front bezel.

When will the 1.2TB 10K SAS drives or the H730P cache battery need replacement?

The eight 1.2TB 10K SAS drives and the H730P 2GB cache battery are the primary maintenance items; drive replacement follows SMART alerts or RAID rebuilds, while the battery typically lasts several years before requiring service.

What thermal or power limit appears first when both Xeon Gold 5118 CPUs run at 3.2GHz turbo under sustained load?

The dual 750W platinum power supplies and 1U chassis cooling set the practical ceiling; sustained 3.2GHz turbo on all 24 cores will hit the platform power budget or thermal envelope before the CPUs reach their individual frequency limits.
