Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rackmount server system built for dense scale-out data centre computing. It ships with two Intel Xeon Silver 4116 processors, each running at 2.1 GHz with 12 cores. The system includes 512 GB of DDR4 registered ECC memory across 16 modules. A PERC H730P storage controller with 2 GB cache handles RAID 0, 1, 5, 6, 10, 50 and 60.

Virtualisation and database workloads

This configuration suits environments that need high core counts and large memory capacity in a single rack unit. The dual Xeon Silver 4116 CPUs provide 24 total cores for parallel workloads. Buyers who need GPU acceleration or more than two processor sockets should evaluate alternative platforms. The eight 2.5-inch drive bays limit internal storage device count compared to larger chassis.

512 GB DDR4 registered ECC memory

The installed 512 GB of DDR4 2400 MHz registered ECC memory occupies 16 of the 24 available DIMM slots. This leaves eight slots open for future expansion up to the 3 TB maximum supported by the Intel C620 chipset. Memory capacity is often the deciding factor for virtualisation density and in-memory database performance. Verify that your workload fits within the current allocation or plan for additional modules.

Questions about this item

What PCIe generation does the PERC H730P controller use, and what throughput does that limit the 12 Gb/s SAS lanes to?

The H730P connects through a PCIe 3.0 x8 link, so each 12 Gb/s SAS lane is capped at the bus throughput of roughly 8 GT/s per lane.

What physical clearance does the 1U R640 need for the Ready Rails and bezel in a standard rack?

The server occupies 1U of rack height; the included Ready Rails mount in a standard four-post cabinet and the front bezel adds minimal depth at the face.

How is the iDRAC9 Enterprise licence activated after the hardware is installed?

iDRAC9 Enterprise is factory-licensed on the system board; no separate key entry is required — simply configure the network settings on first boot to enable remote management.
