DELL PowerEdge M640 blade server 2× Xeon Gold 6230 2.1GHz 20-core 128GB DDR4 2× 960GB SSD

Blade compute density

The Dell PowerEdge M640 is a half-height blade server fitted with two Intel Xeon Gold 6230 processors running at 2.10 GHz with a 3.9 GHz turbo frequency. Each CPU provides 20 cores for a total of 40 threads across the blade. The system ships with 128 GB of DDR4 2666 MHz registered ECC memory installed in eight of sixteen slots. It is intended for virtualization, private cloud and high-performance computing workloads that demand high core counts in a compact chassis slot.

Thermal and power profile

As a blade, the M640 relies on the shared cooling infrastructure of a PowerEdge MX or M1000e enclosure rather than onboard fans. The dual 20-core Xeon Gold 6230 processors have a combined thermal design that the chassis must dissipate under load. Power draw scales with CPU utilisation and the installed SATA SSDs, but the blade form factor concentrates heat in a dense 2.5-inch footprint. Acoustic output is determined by the enclosure fans and will vary with inlet temperature and workload intensity.

Integrated management and networking

The server includes a Broadcom 57810S-K dual-port 10 Gb network daughter card for high-speed fabric connectivity. iDRAC9 Enterprise provides out-of-band remote management with full lifecycle automation and monitoring. The PERC S140 controller manages the two 960 GB SATA SSDs with support for RAID 0, 1, 5 and 10 configurations. No operating system, front bezel or ready rails are included; the blade is designed for direct insertion into a compatible Dell chassis.
