Dual-socket 1U server for dense compute

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 6148 processors, each with 20 cores running at 2.4 GHz. It ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules. A PERC H730P controller with 2 GB cache drives eight 1.2 TB 10K SAS hard drives. Redundant 750 W platinum power supplies, iDRAC9 Enterprise, rails and a front bezel complete the package.

Suits scale-out workloads.

This configuration fits virtualisation clusters, database nodes and high-performance computing where core count and memory capacity matter. Buyers who need GPU acceleration, large all-flash arrays or single-thread frequency above 3.7 GHz should look at other platforms. The 2.5-inch drive bays and SAS interface limit raw capacity compared with 3.5-inch alternatives.

128 GB DDR4 registered ECC across 24 slots

Installed memory is 128 GB of DDR4-2666 registered ECC in eight slots, leaving 16 slots open for expansion up to the 3 TB platform maximum. The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Network I/O uses a quad-port daughter card with two 1 GbE and two 10 Gb SFP+ links.

Questions sur cet article

How do I verify the PERC H730P RAID controller is managing the eight 1.2 TB SAS drives correctly after installation?

Open the controller BIOS during boot or log into iDRAC9 Enterprise to confirm all eight drives appear in a healthy virtual disk with the desired RAID level.

Which components are included and which must be sourced separately for this R640 configuration?

The server ships with two Xeon Gold 6148 CPUs, 128 GB DDR4 (8×16 GB), H730P controller, eight 1.2 TB SAS drives, X520/I350 quad-port NIC, iDRAC9 Enterprise, dual 750 W PSUs, bezel and rails; only an OS licence and rack mounting hardware are not included.

Should I choose the 128 GB DDR4 configuration or plan to populate more of the 24 DIMM slots later?

Start with the installed 128 GB (8×16 GB) if current workloads fit; the 24 slots support up to 3 TB, so additional registered ECC DDR4 modules can be added as demand grows.
