Rack Server with 4 LFF Drive Bays

The Dell PowerEdge R640 is a 1U rack server configured with four 3.5-inch large-form-factor drive bays. It ships with one Intel Xeon Gold 6246R processor running at 3.4 GHz, 16 cores and 35.75 MB cache, plus 32 GB of DDR4 ECC registered memory in two 16 GB modules. The PERC H740P RAID controller manages storage, dual 750 W power supplies provide redundancy, and an iDRAC9 Enterprise licence enables full remote management.

Suited for High-Capacity SATA Arrays

This chassis targets deployments that need up to four 3.5-inch SATA hard drives for bulk capacity, such as file servers, backup targets or archive workloads. The single-socket design leaves the second CPU socket available for future expansion. Buyers who require more than four drive bays, 2.5-inch drive density, or a second processor installed from the factory should evaluate alternative configurations.

PERC H740P RAID Controller Decides Fit

The installed Dell PERC H740P controller determines which RAID levels and drive types are supported for the four SATA bays. Verify that its feature set matches your redundancy and performance requirements before purchase, as the controller is not user-swappable in this 1U form factor.

Questions about this item

Will my existing DDR4 ECC registered DIMMs work with the 32GB already installed in this R640?

Yes, the system uses DDR4 ECC registered memory and supports up to 7.68TB total capacity across its slots.

How can I confirm the PERC H740P RAID controller and iDRAC9 Enterprise are active after power-on?

During POST the H740P BIOS will list detected drives and the iDRAC9 network settings appear; both can also be verified in the Lifecycle Controller.

Does the box include drive caddies for the four 3.5-inch bays and rails for rack mounting?

The chassis provides four 3.5-inch bays; drive caddies and a rail kit are optional and must be requested separately.
