Dual-processor blade for dense compute

The Dell PowerEdge M640 is a half-height blade server fitted with two Intel Xeon Platinum 8260 processors. Each CPU runs at 2.4 GHz with a 3.9 GHz turbo and provides 24 cores. The system ships with 512 GB of DDR4 memory across 16 slots and two 1.92 TB NVMe SSDs managed by a PERC S140 controller. It is built for virtualization, private cloud and high-performance computing in MX or M1000e chassis.

Suited for scale-out workloads needing maximum

This blade targets operators who need high core density and fast NVMe storage in a shared chassis. Buyers who require GPU acceleration, larger local storage bays or a standalone rackmount form factor should look elsewhere. The integrated Matrox G200 graphics only supports basic console output.

Two-socket LGA 3647 limit defines maximum CPU

The board accepts up to two processors in LGA 3647 sockets, so the installed pair of 24-core Xeons already reaches the ceiling. Memory can grow to 1.5 TB using the remaining DDR4 slots, but processor count cannot increase beyond two.

Questions about this item

Does the blade ship with a front bezel or ready rails, or must they be purchased separately?

The front bezel and ready rails are not included with this blade and must be purchased separately.

Should I choose the 512 GB DDR4 configuration or plan to add memory later for the 2 TB maximum?

The server arrives with 512 GB installed across 16 slots using 32 GB DDR4 2933 MHz registered ECC modules, leaving no free slots; reaching the 2 TB maximum would require replacing all modules with higher-capacity DDR4 DIMMs.

What real-world throughput can I expect from the two 1.92 TB NVMe drives on the PERC S140 controller?

The two 1.92 TB U.2 NVMe PCIe Gen3 drives connect through the integrated PERC S140 controller, which supports RAID 0, 1, 5 and 10; actual throughput will depend on the RAID level chosen and the workload pattern.
