Dense 1U compute node

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre workloads. It ships with two Intel Xeon Silver 4110 8-core processors at 2.1 GHz, 128 GB of DDR4 registered ECC memory, and eight 400 GB SATA SSDs behind a PERC H730P hardware RAID controller. Dual 750 W platinum power supplies and iDRAC 9 Enterprise provide redundant power and remote management.

Virtualisation hosts and storage-heavy workloads

The configuration suits virtualisation clusters, database nodes and high-density storage tiers that benefit from 24 DIMM slots, hardware RAID 0/1/5/6/10/50/60 and quad-port 1/10 GbE networking. Buyers who need GPU acceleration or more than eight front-accessible 2.5-inch bays should look elsewhere.

24 DDR4 slots and 3 TB memory ceiling

The single specification that decides fit is the 24-slot DDR4 architecture supporting up to 3 TB of registered ECC memory, which determines whether the platform can grow with your workload.

Questions about this item

What speed does the 12Gb/s SAS controller cap at with the installed 6Gb/s SATA SSDs?

The eight 400GB SATA SSDs run at 6Gb/s, so the H730P controller's 12Gb/s SAS lanes are limited to the drives' native 6Gb/s link speed.

What rack depth do the included Ready Rails require for this 1U chassis?

The supplied Ready Rails mount in standard four-post racks and support adjustable depths common to 1U Dell servers; verify your rack's inner rail spacing before installation.

How are the two Xeon Silver 4110 processors seated, and which slot order is often missed?

Both LGA 3647 sockets are populated; install CPU 1 first, then CPU 2, ensuring each heat-sink latch fully engages — skipping the second socket leaves the system unbootable.
