Purpose-built virtualization server
The Dell PowerEdge R640 is a 1U rackmount system configured with two Xeon Gold 6136 processors running at 3.00GHz, delivering 24 cores and 48 threads. It ships with 64GB of DDR4 ECC Registered memory and eight 1.2TB 10K SAS drives, making it suited for virtualization, database, and high-speed transactional workloads.
Compatibility checklist
Verify your rack provides 1U of space and sufficient power and cooling for a 60-unit weight chassis. Confirm the PERC H740P RAID controller matches your existing storage topology and that the dual 10GbE X540 plus dual 1GbE I350 network ports align with your switch infrastructure. Ensure the SAS backplane supports the installed 2.5-inch drive form factor.
Build and connectivity
Hot-swap 2.5-inch bays allow drive replacement without downtime, while the H740P controller simplifies array management. Front-panel LEDs for power, Ethernet, and USB give immediate status visibility. Integrated GPU handles basic console output without occupying a PCIe slot. The dense 1U design maximises compute density in standard rack rows.

Questions about this item
Does the server ship with rails, bezel or power cables, or must they be purchased separately?
The unit is sold as the server chassis only. Rails, bezel and power cords are not included and must be sourced separately.
Should I choose the 64 GB DDR4 configuration or add modules up to the 3 TB maximum?
Start with the installed 64 GB DDR4 ECC Registered memory; add identical DDR4 modules later if workloads exceed the current capacity.
What does the 3.00 GHz base clock on the dual Xeon Gold 6136 CPUs deliver in a live virtualization host?
Twenty-four cores and forty-eight threads at 3.00 GHz provide consistent throughput for multiple VMs and IOPS-heavy workloads.
