Server purpose
The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, file storage and application hosting. Dual Intel Xeon Silver 4114 processors deliver 20 cores at 2.20GHz with 64GB DDR4 ECC memory. Eight 1.2TB 10k SAS drives and a PERC H740P controller provide high-speed storage capacity.
Compatibility checks
Verify that your rack accepts 1U form factor and provides sufficient depth for the 60 weight unit. Confirm the power infrastructure supplies appropriate voltage for dual-processor operation. Ensure network switches support 10GbE X540 and 1GbE I350 connectivity. Check that your operating system and hypervisor are certified for this hardware configuration.
Thermals and power
Redundant cooling fans maintain stable temperatures across both CPUs and the eight drive bays under typical virtualization loads. Acoustic output is managed for data-centre environments rather than office spaces. Power draw scales with workload across the dual 10-core processors, memory and storage subsystem. The H740P controller adds minimal overhead during normal RAID operations.

Questions about this item
What comes in the box with the PowerEdge R640 and do I need to buy any drives separately?
The server includes two Xeon Silver 4114 processors, 64GB DDR4 ECC memory, the PERC H740P RAID controller and eight 1.2TB 10k SAS drives already installed in the 2.5-inch bays; no additional drives are required to start.
Which drive configuration should I choose for virtualization — the eight 1.2TB SAS drives or the two 960GB SSDs?
The eight 1.2TB 10k SAS drives give more total capacity and sustained throughput for multiple VMs, while the two 960GB SSDs offer lower latency for boot volumes or high-IOPS databases; pick based on whether capacity or latency is the priority.
What does the 20-core total mean for real-world VM density on this R640?
With 20 cores at 2.20GHz and 64GB DDR4 you can run a moderate number of virtual machines — typically several dozen light workloads or fewer heavier ones — limited more by the 64GB memory ceiling than by CPU threads.
