Four 3.5" drive bay chassis
The Dell PowerEdge R640 is a 1U rack server configured with four large-form-factor bays for 3.5-inch SATA drives. Two Intel Xeon Gold 5120 processors at 2.2 GHz provide 28 cores in total, backed by 128 GB of DDR4 ECC registered memory. A PERC H740P RAID controller and a 10 GbE two-port 562T adapter handle storage and network traffic. Remote management is covered by iDRAC9 Enterprise, and dual 750 W power supplies deliver redundancy.
Suits virtualisation hosts needing dense 3.5"
This configuration fits workloads that demand high core counts and large-capacity hard drives in a single rack unit. Buyers who require more than four drive bays, GPU acceleration, or a different drive interface should evaluate alternative platforms. The fixed two-processor maximum also limits future CPU expansion beyond the installed pair.
PERC H740P RAID controller with 10 GbE networking
The integrated PERC H740P controller manages RAID across the four 3.5-inch SATA bays, while the onboard 562T adapter supplies two 10 GbE ports for high-throughput connectivity. This combination determines whether the server matches your storage-performance and network-bandwidth requirements.

Questions about this item
What is included with the Dell PowerEdge R640 4LFF and what must be purchased separately?
The server ships with 2x Xeon Gold 5120 processors at 2.2GHz, 128GB DDR4 ECC registered memory, a PERC H740P RAID controller, a 10GB 2-port 562T network adapter, and 2x 750W power supplies. No 3.5" drives are installed; they must be bought separately.
Which drive capacity should I choose for the four 3.5" bays?
Each bay accepts a 3.5" SATA drive. Pick capacities that match your storage target and the PERC H740P RAID level you plan — larger drives give more raw space, smaller drives can lower cost per bay.
What does the 128GB DDR4 figure mean for actual workloads?
128GB of DDR4 ECC registered memory lets you run multiple virtual machines or databases simultaneously, with headroom to expand up to 7.68TB across the remaining slots.
