Dense Dual-Socket 1U Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data center computing. It ships with two Intel Xeon Platinum 8160 processors, each running at 2.1 GHz with 24 cores and a 3.7 GHz turbo frequency. The system includes 64 GB of DDR4 2666 MHz registered ECC memory across four 16 GB modules. Dual 750 watt platinum-efficiency power supplies provide redundant hot-swap power.

Virtualisation Hosts, Not GPU Workloads

This server suits organisations consolidating virtual machines, running databases or deploying high-performance computing clusters where CPU core count and memory bandwidth matter. The quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who need GPU acceleration or large local storage arrays should look at a different platform because the 1U chassis limits expansion slots and drive bays.

Eight-Bay 2.5-Inch Front Storage

The chassis provides eight hot-swap 2.5-inch drive bays populated with two 400 GB SATA SSDs on a Dell PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. The controller uses a 12 Gb/s SAS/SATA interface with battery-backed cache. iDRAC 9 Enterprise enables full remote management. Ready rails and a front bezel are included for immediate rack installation.

Questions about this item

What rack height and rail kit does the R640 need for mounting?

The server occupies 1U of rack space and includes Ready Rails for tool-less installation in standard cabinets.

How are the Xeon Platinum 8160 processors and DDR4 memory installed, and what step is often missed?

Both CPUs are pre-installed in the LGA 3647 sockets; the four 16 GB DDR4 modules populate the first four slots — skipping the prescribed slot order reduces memory bandwidth.

When will the PERC H730P controller battery and the 750 W power supplies need replacement?

The RAID controller battery typically lasts three to five years; each hot-swap 750 W Platinum supply can be replaced independently without downtime.
