Dense compute platform

The Dell PowerEdge R640 is a 1U rack server built for scale-out workloads that demand high core counts in minimal space. Two Intel Xeon Gold 6142 processors deliver 32 cores at 2.6 GHz with 3.7 GHz turbo, backed by 512 GB of DDR4-2666 registered ECC memory across 24 slots. The PERC H730P controller manages up to eight 2.5-inch drives with hardware RAID and battery-backed cache.

Upgrade from single-socket density

This configuration replaces single-socket 1U servers when thread count and memory capacity become the bottleneck. The jump is worth it for virtualization clusters, database nodes or HPC front-ends that need 32 cores and up to 3 TB of memory in a single rack unit. Buyers who need more internal drive bays or GPU acceleration will not find them here.

Rack-ready integration

Dual 750 W platinum power supplies and hot-swap bays keep the chassis running during maintenance. The X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports for flexible network fabric. iDRAC 9 Enterprise gives full out-of-band control, while included rails and bezel simplify cabinet installation.

Questions sur cet article

What rack depth and rail kit does the 1U PowerEdge R640 require for mounting?

The server is a 1U rack unit and ships with Ready Rails for tool-less installation in standard 4-post racks.

How are the two Xeon Gold 6142 processors and 16 DDR4 memory modules installed, and what step is often missed?

Both LGA 3647 sockets are already populated; the 16 installed 32 GB DDR4 modules fill 16 of the 24 DIMM slots in the correct channel order.

Which components in the R640 are hot-swappable and may need replacement during its service life?

The two 750 W power supplies, the eight 2.5" drive bays, and the PERC H730P controller battery are all hot-swappable field-replaceable units.
