Dual-socket 1U compute density

This Dell PowerEdge R640 is a new 1U rack server built for dense scale-out workloads. Two Intel Xeon Silver 4116 processors provide 24 total cores at 2.1 GHz with 3.0 GHz turbo. The system ships with 256 GB of DDR4 2400 MHz registered ECC memory across eight 32 GB modules. A PERC H730P controller and dual 400 GB SATA SSDs handle storage duties.

Verify rack depth and network cabling

Confirm your rack can accommodate a 1U chassis with ready rails and that power distribution can supply two 750 W platinum hot-swap supplies. The installed quad-port daughter card delivers two 1 GbE and two 10 Gb SFP+ links, so plan matching switch ports and SFP+ modules. Memory uses DDR4 RDIMMs only; do not mix generations. The H730P supports RAID 0, 1, 5, 6, 10, 50 and 60.

Fits dense virtualization and database tiers

The R640 frees rack space by packing dual-socket performance into 1U, leaving room for additional compute nodes. Eight 2.5-inch drive bays allow future storage expansion without a larger chassis. Redundant power and iDRAC 9 Enterprise remote management keep the platform running during maintenance windows. The Intel C620 chipset and 24 DIMM slots support up to 3 TB of memory when workloads grow.

Questions about this item

Does the 1U rack server ship with rails and a bezel, or must they be ordered separately?

Ready Rails and a front bezel are included in the box, so no separate purchase is required.

Should I choose the 256 GB DDR4 configuration or plan to fill all 24 slots up to 3 TB?

The unit arrives with 8 × 32 GB modules for 256 GB total; 16 slots remain open for future expansion to the 3 TB maximum.

What does the 2.1 GHz base clock with 3.0 GHz turbo mean for sustained workloads on the dual Xeon Silver 4116 CPUs?

Each 12-core processor runs at 2.1 GHz base and can boost to 3.0 GHz under load, giving 24 cores total for parallel tasks.
