Dense 1U dual-socket 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. The system includes 64 GB of DDR4 registered ECC memory and eight 400 GB SATA SSDs managed by a PERC H730P storage controller. Redundant 750-watt power supplies and iDRAC 9 Enterprise remote management complete the package.

For virtualisation hosts and scale-out clusters.

This configuration suits organisations deploying virtualisation hosts, high-density compute clusters or storage-intensive applications that benefit from dual-socket performance in a 1U form factor. Buyers who need GPU acceleration, larger local storage capacity or single-threaded frequency above 3.7 GHz turbo should evaluate alternative platforms.

PERC H730P controller with 2 GB cache

The installed Dell PERC H730P storage controller provides 2 GB of battery-backed cache and supports RAID levels 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. It connects to the eight 2.5-inch SATA SSDs through a 12 Gb/s SAS/SATA interface, determining the storage performance and redundancy options available for this server.

Questions about this item

What comes in the box and what do I need to add?

The server ships with two Xeon Platinum 8160 CPUs, 64 GB DDR4 in four 16 GB modules, eight 400 GB SATA SSDs, a PERC H730P controller with battery, a quad-port X520/I350 network card, iDRAC9 Enterprise, dual 750 W redundant PSUs, ready rails and a front bezel. No extra parts are required for basic operation.

Which memory configuration should I choose for this R640?

The system has 24 DDR4 slots and currently holds 64 GB across four 16 GB registered ECC modules running at 2666 MHz. You can expand up to 3 TB by filling the remaining slots with matching DDR4 RDIMMs.

What does the 2.1 GHz base clock mean once the server is running workloads?

Each Xeon Platinum 8160 runs at 2.1 GHz base and can reach 3.7 GHz turbo across its 24 cores, delivering high single-thread speed and strong multi-thread throughput for dense scale-out tasks.
