Dense 1U dual-socket compute

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 6148 processors running at 2.40 GHz with 20 cores each. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules. A PERC H730P RAID controller with 2 GB cache manages two 400 GB SATA SSDs. Redundant 750 W platinum power supplies, iDRAC9 Enterprise, quad-port networking and rails are included.

Virtualisation hosts needing maximum cores per U

This configuration suits dense virtualisation, container clusters or database nodes that benefit from 40 total cores and large memory capacity in a single rack unit. The eight 2.5-inch drive bays and dual 10 Gb SFP+ ports support high-throughput storage and network fabrics. Buyers who require more than two processor sockets, GPU acceleration or additional drive bays should evaluate alternative platforms.

PERC H730P RAID controller with 2 GB cache

The storage controller defines which RAID levels are available and whether a battery-backed cache protects in-flight writes. This unit provides RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Confirm that the supported SATA and SAS interface matches your drive selection before purchase.

Questions sur cet article

How can I verify the two Xeon Gold 6148 processors and 256 GB DDR4 memory are recognised after powering on the R640?

During POST the system BIOS will display two 20-core CPUs at 2.4 GHz and 256 GB of registered ECC DDR4 across the 24 DIMM slots; iDRAC9 Enterprise also reports the same inventory remotely.

Which components are included with the server and which items must be sourced separately?

The unit ships with two Xeon Gold 6148 CPUs, 256 GB DDR4 (eight 32 GB modules), PERC H730P 2 GB controller, two 400 GB SATA SSDs, X520/I350 quad-port network card, iDRAC9 Enterprise, two 750 W redundant PSUs, bezel and ready rails; additional drives or memory must be purchased separately.

Should I choose the 400 GB SSD configuration or add larger drives for more capacity?

The included two 400 GB SATA SSDs provide fast boot and cache tiers; the 8-bay 2.5" chassis supports up to six extra SATA or SAS drives, so capacity can be expanded without replacing the factory SSDs.
