Dell PowerEdge R640 Virtualisation Server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualisation, databases and application hosting. Dual Intel Xeon Gold 6148 processors deliver 40 cores at 2.40 GHz with 256 GB DDR4 memory installed. Eight 1.2 TB 10K SAS drives and an H730P controller provide storage capacity for virtual machines and data.

Pre-Installation Checks

Verify the rack provides 1U space and adequate airflow for a 60 kg unit. Confirm the power infrastructure can supply dual redundant supplies for two 20-core CPUs and eight SAS drives. Ensure the H730P controller firmware is current before adding the drives to an array. Check that network uplinks support the integrated X550-T4 10 GbE ports.

Sustained Load Behaviour

Under continuous virtualisation or database load the dual Gold 6148 CPUs maintain 2.40 GHz across all 40 cores. The H730P controller manages steady write throughput to the eight 1.2 TB SAS drives. DDR4 memory capacity of 256 GB supports persistent multi-VM operation without swapping. Integrated GPU handles remote management console output without affecting compute resources.

Questions about this item

What drives are included with the PowerEdge R640 and do I need to buy any storage separately?

Eight 1.2TB 10K SAS drives are installed in the 2.5-inch bays; no additional drives are required for the configured capacity.

How do I decide between the 40-core Gold 6148 configuration and a lower-core option for virtualization?

The dual Gold 6148 CPUs deliver 40 cores at 2.4GHz, which matches the spec sheet for heavy virtualization workloads; choose this version when you need maximum thread count.

What does the 256GB DDR4 figure mean for actual VM density on this server?

With 256GB DDR4 installed and a 3TB ceiling, you can run dozens of typical virtual machines before hitting the memory limit.
