Dense 1U compute for scale-out workloads

The Dell PowerEdge R640 packs two Xeon Gold 6134 processors and 128GB of DDR4 memory into a single rack unit. Eight 400GB SATA SSDs attach to a PERC H730P controller with 2GB cache. Dual 750W platinum power supplies and iDRAC9 Enterprise management complete the package.

Suits virtualization and database clusters.

This server fits teams running virtualization, databases or high-performance computing in a dense footprint. The 1U chassis leaves no room for full-length accelerator cards, so workloads that rely on GPU compute should look elsewhere. Buyers needing more than 24 DIMM slots or more than eight 2.5-inch drive bays will need a larger platform.

Dual Xeon Gold 6134 at 3.2GHz with 8 cores each

Two processors deliver 16 total cores at a 3.2GHz base clock and 3.7GHz turbo. The LGA 3647 socket and C620 chipset support up to 3TB of DDR4 across 24 slots. This CPU configuration is the fixed performance ceiling — no further processor upgrades are possible.

Questions about this item

Will my existing 2.5" SATA drives work in the eight drive bays?

The server has eight 2.5" bays wired for SATA and the PERC H730P controller supports SATA SSDs and HDDs, so current 2.5" SATA drives will install and be recognised.

How can I confirm the dual Xeon Gold 6134 CPUs and 128 GB DDR4 are running at 3.2 GHz base and 2666 MHz memory speed?

Open the iDRAC9 Enterprise interface or the system BIOS after first boot; both show each processor at 3.2 GHz base with 3.7 GHz turbo and the eight 16 GB DDR4 modules at 2666 MHz.

Which items ship with the chassis and which must be sourced separately?

The box contains the 1U chassis, two Xeon Gold 6134 CPUs, 128 GB DDR4 ECC memory, PERC H730P with battery, eight 400 GB SATA SSDs, X520/I350 quad-port card, iDRAC9 Enterprise, two 750 W PSUs, bezel and rails. No extra parts are required for basic operation.
