DELL PowerEdge M640 Blade 2x Xeon Gold 6240 384GB DDR4 2x 1.8TB SAS

Blade server for dense compute

The Dell PowerEdge M640 blade fits into a shared chassis and delivers two Xeon Gold 6240 processors at 2.60 GHz with 18 cores each. It ships with 384 GB of DDR4 ECC registered memory and two 1.8 TB SAS hard drives managed by a PERC H330 controller. This configuration targets virtualisation clusters and database workloads that benefit from high core counts in a compact form factor.

Thermals and power in normal use

Dual processors and 384 GB of DDR4 draw significant power, so the blade relies on the chassis cooling fans and shared power supplies to maintain safe temperatures. Integrated graphics and the 10 GbE 562T adapter add minimal heat during typical operation. iDRAC9 Enterprise provides remote thermal monitoring and power capping without a local display or keyboard.

Behaviour under sustained load

Under continuous multi-threaded workloads the 36 combined cores and 24.75 MB cache per CPU sustain throughput while the chassis airflow handles the resulting heat. SAS drives and the PERC H330 controller maintain consistent I/O latency during long-running jobs. Memory capacity can be expanded to 1 TB if datasets grow beyond the installed 384 GB.
