Half-height blade server for dense compute

The Dell PowerEdge M640 is a half-height blade server that fits the PowerEdge MX and M1000e chassis. It ships with two Intel Xeon Gold 6150 processors, each running 18 cores at 2.70 GHz with a 3.7 GHz turbo frequency. Installed memory is 64 GB of DDR4 across four 16 GB modules, leaving twelve slots open for expansion up to 1.5 TB. The PERC H330 controller manages two 960 GB SATA SSDs in a 2.5-inch bay.

Suits virtualisation and HPC clusters.

This blade targets virtualisation, private cloud and high-performance computing clusters that need maximum CPU density per rack unit. The dual 18-core configuration and large memory ceiling support heavy multi-threaded workloads. Buyers who need GPU acceleration, local NVMe storage or a standalone tower or rack-mount form factor should look elsewhere because the half-height blade design excludes full-length add-in cards and requires a compatible MX or M1000e enclosure.

Dual 18-core Xeon Gold 6150 CPUs

The decisive specification is the pair of Intel Xeon Gold 6150 processors delivering 36 total cores at 2.70 GHz base and 3.7 GHz turbo. This core count and frequency determine whether the blade meets the throughput requirements for your virtualisation host or compute cluster. All other resources — memory slots, drive bays and the 10 Gb dual-port network card — scale around this CPU foundation.

Questions about this item

How do I install this blade into an M1000e or MX chassis, and what step is often missed?

Slide the half-height blade into an empty bay until the latch clicks, then use the iDRAC9 Enterprise interface to inventory the server and update firmware before powering on the operating system.

Which components will need replacement first under continuous operation?

The two 960GB SATA SSDs have a finite write endurance; monitor their SMART health via iDRAC9 and plan replacement when the media-wear indicator approaches the rated limit.

What thermal or power limit appears first when both Xeon Gold 6150 CPUs run at 3.7 GHz turbo across all 18 cores?

The blade's shared cooling and chassis power budget will throttle the 2.7 GHz base frequency before sustained 3.7 GHz all-core turbo can be maintained.
