Blade server for dense compute

The Dell PowerEdge M640 is a half-height blade that fits into PowerEdge MX or M1000e chassis. It ships with two Intel Xeon Gold 6154 processors running at 3.0 GHz with a 3.7 GHz turbo frequency. Each CPU provides 18 cores for a total of 36 cores in this configuration. The system includes 32 GB of DDR4 2666 MHz registered ECC memory across four modules.

Upgrades from single-socket blades

This unit replaces a single-processor blade when workloads demand higher core counts and larger memory capacity. The jump is worth it when virtualisation density or database threading exceeds what one socket can deliver. The integrated PERC S140 controller supports RAID 0, 1, 5 and 10 across two 2.5-inch drive bays for local storage redundancy.

Suits virtualisation and HPC clusters

Organisations building private cloud or high-performance computing clusters will benefit from the 10 Gb dual-port Broadcom 57810S-K network daughter card and iDRAC9 Enterprise remote management. Buyers who need GPU acceleration, more than two processors or fibre-channel connectivity should look at alternative platforms.

Questions about this item

Does the M640 blade require a PowerEdge MX or M1000e chassis to operate?

Yes, the half-height M640 blade installs only inside a Dell PowerEdge MX or M1000e chassis; it cannot run as a standalone unit.

How do I install the Broadcom 57810S-K 10Gb dual-port network daughter card, and what step is often missed?

Slide the card into the dedicated mezzanine slot on the blade motherboard and secure the retention screw; the step often missed is connecting the card's external cables through the chassis I/O module before powering on.

What maintenance will the blade's DDR4 memory require later?

DDR4 ECC registered modules are solid-state with no moving parts; they need no scheduled maintenance, but a failed DIMM must be replaced with an identical 2666MHz registered ECC module to keep the memory bus stable.
