Dense 1U server for virtualisation

The Dell PowerEdge R640 packs two Xeon Gold 6138 processors into a 1U rackmount chassis, delivering 40 cores at 2.00GHz. Sixteen gigabytes of DDR4 memory and an H730 storage controller support business workloads such as virtualisation, databases and application hosting. Ten 2.5-inch drive bays, eight of them NVMe-capable, provide high-density local storage.

Suits dense compute clusters.

This configuration fits environments that need many cores in minimal rack space and fast NVMe storage for virtual machines or databases. Buyers who require GPU acceleration, larger installed memory for in-memory analytics, or additional PCIe expansion slots should evaluate other platforms. The integrated graphics and single 16GB module limit visualisation and high-capacity memory scenarios.

Eight NVMe-capable bays set the storage ceiling

The chassis offers ten 2.5-inch trays, with eight wired for direct NVMe attachment to the CPU lanes. This NVMe bay count determines how many high-speed drives can be installed without extra cabling or adapters, directly shaping maximum IOPS and throughput for the workloads listed above.

Questions about this item

Should I pick the 40-core total or the 24-core per CPU option?

The server contains two Xeon Gold 6138 processors, each with 24 cores, giving a combined 40 cores for the system.

What does the 2.00 GHz base clock mean for virtualization density?

Both CPUs run at 2.00 GHz, providing consistent frequency across all 40 cores to sustain multiple virtual machines.

How does the H730 controller limit the 10 NVMe-capable bays?

The H730 manages RAID for traditional drives; the 8 NVMe-capable bays connect directly to the CPU for native NVMe speed.
