DELL PowerEdge M640 blade server 2× Xeon Gold 6150 2.7 GHz 18-core 16 GB DDR4 S140 57810S-K iDRAC9 Enterprise

Blade density and compute scale

The Dell PowerEdge M640 is a half-height blade server built for data-centre workloads such as virtualisation, private cloud and high-performance computing. It ships with two Intel Xeon Gold 6150 processors, each running at 2.70 GHz with a 3.7 GHz turbo frequency and 18 cores, delivering up to 56 cores per server. Sixteen gigabytes of DDR4 2666 MHz registered ECC memory is installed across two modules, and the platform supports up to 1.5 TB total capacity.

Thermal design and power profile

The blade form factor relies on the shared cooling infrastructure of a PowerEdge MX or M1000e chassis, so individual fan noise and power draw are managed at enclosure level rather than by the server itself. The PERC S140 integrated controller handles SATA and NVMe storage with RAID 0, 1, 5 and 10 support, while the Broadcom 57810S-K dual-port 10 Gb network daughter card provides high-throughput connectivity. A Matrox G200 GPU with 8 MB video memory supplies basic console output.

Upgrade path and fit

This configuration replaces older half-height blades that lack NVMe support or dual 10 Gb networking, and it upgrades from single-socket or lower-core-density platforms when workloads demand more parallel threads. The jump is worth it for teams consolidating virtual machines or scaling memory-intensive applications within existing chassis slots. Buyers who need local GPU acceleration, Fibre Channel connectivity or more than two 2.5-inch drive bays will find this blade does not meet those requirements.
