Dual-socket 1U server

The Dell PowerEdge R640 is a 1U rack server designed for dense scale-out data centre computing. It ships with two Intel Xeon Silver 4110 processors running at 2.1 GHz with eight cores each. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Eight 400 GB SATA solid-state drives provide internal storage.

Suited for virtualisation and database workloads

This configuration suits organisations that need dual-socket performance in a single rack unit with redundant 750 W power supplies. The PERC H730P controller supports RAID levels 0, 1, 5, 6, 10, 50 and 60 for flexible data protection. Buyers who need more than 24 memory slots or a different drive interface should evaluate alternative platforms.

256 GB DDR4 registered ECC memory installed

The installed 256 GB of DDR4 2400 MHz registered ECC memory fills eight of the 24 available slots and uses the LGA 3647 platform. This capacity determines how many virtual machines or database instances can run concurrently. Memory type and speed are fixed by the processor generation and cannot be changed to a different DDR generation.

Questions about this item

What comes in the box and what must I purchase separately?

The server ships with dual Xeon Silver 4110 processors, 256 GB DDR4 in eight 32 GB modules, eight 400 GB SATA SSDs, a PERC H730P controller, quad-port X520/I350 networking, iDRAC9 Enterprise, dual 750 W PSUs, rails and bezel. Additional drives or memory are optional.

Which memory configuration should I choose for this R640?

The system includes 256 GB (8×32 GB) DDR4 2400 MHz registered ECC. Twenty-four DIMM slots exist; populate remaining slots in matched sets to reach the 3 TB maximum.

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

Each Xeon Silver 4110 runs at 2.1 GHz base with 3.0 GHz turbo across its eight cores, so sustained throughput depends on cooling and load while burst performance can reach the higher frequency.
