Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for scale-out data center workloads. It ships with two Intel Xeon Gold 6134 processors running at 3.2 GHz with eight cores each. The system includes 64 GB of DDR4 2666 MHz registered ECC memory across four modules. Eight 800 GB SATA SSDs provide high-density flash storage in a compact form factor.

Upgrade from single-socket or HDD platforms

This configuration replaces single-socket servers or systems still using mechanical drives when parallel throughput and redundancy matter. The jump is worth it for virtualization clusters, database nodes, or HPC front-ends that need two 8-core CPUs and hardware RAID. Buyers who need more than 3 TB of memory or more than two processors should look elsewhere.

Limited by SATA SSD bandwidth and 1U thermals

The PERC H730P controller supports 12 Gb/s SAS and SATA, but the installed drives run on the 6 Gb/s SATA interface, capping sequential throughput. The 1U chassis constrains airflow, so sustained all-core turbo at 3.7 GHz depends on inlet temperature and workload profile. The 24 DIMM slots allow expansion to 3 TB, yet the 750 W power supplies limit total platform power under full load.

Questions about this item

How much clearance do the 2.5-inch drive bays and included rails need in a 1U rack?

The server occupies a single 1U rack height and uses eight 2.5-inch SATA SSD bays; the supplied Ready Rails mount in a standard four-post rack.

What is the correct order for installing the two Xeon Gold 6134 processors and the 64GB DDR4 memory?

Install both LGA 3647 processors first, then populate the 24 DDR4 slots starting with the four 16GB modules supplied, following the R640 memory population rules.

Which components are hot-swappable and what replacement schedule applies to the PERC H730P battery?

The eight 800GB SSDs and both 750W power supplies are hot-swappable; the H730P controller battery should be replaced per Dell's recommended service interval.
