Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack-mount server configured with four 3.5-inch drive bays. It ships with one Intel Xeon Silver 4116 processor running at 2.1GHz and 64GB of DDR4 ECC registered memory. A PERC H740P RAID controller and dual 750W power supplies are installed. The iDRAC9 Enterprise licence provides remote management. No hard drives are included.

Suited for memory-heavy workloads.

This configuration suits workloads that benefit from a large memory pool relative to core count, such as in-memory databases or virtualisation hosts with dense VM ratios. Buyers who need two processors or more than twelve cores per socket should look at a different specification. The single-socket layout limits the maximum thread count available for heavily parallel tasks. Expansion to a second CPU is possible but requires additional parts.

Four 3.5-inch SATA drive bays

The chassis provides four hot-plug 3.5-inch bays wired for SATA drives and managed by the PERC H740P controller. This bay count determines how many large-capacity drives you can install internally without adding external enclosures. If your storage plan requires more than four mechanical drives, this chassis will not accommodate them. Drive selection and RAID layout remain open to your requirements.

Questions about this item

What does the 2.1 GHz speed of the Xeon Silver 4116 mean for real-world server workloads?

The single Xeon Silver 4116 runs at 2.1 GHz with 12 cores and 16.5 MB cache, delivering multi-threaded performance for virtualization, databases and general compute tasks in this R640.

How does the PERC H740P controller and SATA interface limit drive performance in the 4LFF chassis?

The PERC H740P manages up to four 3.5-inch SATA drives; the SATA link caps each drive at 6 Gb/s, so sequential throughput is limited by the drive and interface, not the RAID card.

What physical space and mounting hardware does the R640 4LFF need to install in a rack?

The unit measures 36 x 24 x 10 inches and weighs 40 lbs; it occupies 1U and mounts in a standard rack using Dell sliding rail kits available on request.
