Ready-to-configure rack server

The Dell PowerEdge R640 4LFF is a 1U rackmount server built around two Intel Xeon Platinum 8260L processors running at 2.4 GHz. It ships with 384 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. No drives are installed, so storage can be specified to match the workload.

Suited to virtualisation hosts and database nodes

The dual-socket design and large memory capacity fit consolidation, virtualisation or in-memory database roles where core count and RAM matter. Buyers who need more than two processors or who require GPU acceleration should look at larger chassis options.

Four 3.5-inch drive bays define storage limits

The 4LFF chassis accepts up to four 3.5-inch SATA drives, so total raw capacity is capped by the number and size of drives you install. Plan drive selection around that four-bay constraint.

Questions about this item

How do I install the 3.5" drives into the 4LFF chassis and what step is often missed?

Slide each drive into a bay until the latch clicks, then run the PERC H740P configuration utility to create a virtual disk before the OS sees any volume.

What component will need replacement first during long-term operation?

The two 750 W power supplies are the only field-replaceable parts with moving fans; plan to swap one after several years of continuous duty.

What thermal limit appears first when both Xeon Platinum 8260L CPUs run at 2.4 GHz under sustained load?

The 1U chassis airflow ceiling is reached before the CPU TDP limit, so inlet temperature must stay within spec to avoid throttling.
