Blade density and compute

The Dell PowerEdge M640 is a half-height blade server built for virtualization, private cloud and high-performance computing workloads. Two Intel Xeon Gold 6150 processors deliver 36 cores at 2.7 GHz with 3.7 GHz turbo, fitting into MX or M1000e chassis for high-density deployments.

Memory ceiling and storage speed

Installed memory is 64 GB DDR4 across four 16 GB modules with 16 slots total, supporting up to 1.5 TB for large dataset workloads. The PERC S140 controller manages the two 1.92 TB SATA SSDs in RAID 0, 1, 5 or 10, while the SATA/SAS interface also accepts NVMe drives for faster tiers.

Upgrade path and management scope

This configuration replaces older blade servers that max out at lower core counts or memory limits, adding 10 Gb dual-port networking via the 57810S-K daughter card. iDRAC9 Enterprise provides full remote lifecycle management, making the jump worthwhile when automation and density gains outweigh the cost of a chassis refresh.

Questions about this item

Will the M640 blade fit and run in my existing PowerEdge M1000e chassis?

Yes, the half-height M640 blade is designed to integrate directly into both PowerEdge MX and M1000e chassis for flexible deployment.

How can I verify the two Xeon Gold 6150 processors and 64 GB DDR4 are detected after installation?

Use the iDRAC9 Enterprise remote management interface to confirm both 18-core CPUs at 2.7 GHz and the four 16 GB DDR4 2666 MHz modules are reported.

Does the shipment include front bezel, ready rails or an operating system licence?

The unit ships without front bezel, ready rails or an installed operating system; those items must be sourced separately.
