High-density blade for compute workloads

The Dell PowerEdge M640 is a half-height blade server that fits into PowerEdge MX and M1000e chassis. Two Intel Xeon Gold 6154 processors run at 3.0 GHz with a 3.7 GHz turbo, providing 36 cores in total for virtualization, private cloud or high-performance computing tasks.

Integrated controller and 10 Gb networking

A Dell PERC S140 controller manages the two installed 1.92 TB SATA SSDs with RAID 0, 1, 5 or 10. The Broadcom 57810S-K dual-port 10 Gb blade network daughter card and iDRAC9 Enterprise remote management are included, while front bezel and ready rails are not supplied.

Suited for chassis-based deployments

This blade suits IT teams that already operate a compatible Dell chassis and need dense, scalable compute with integrated 10 Gb connectivity. Buyers who require a standalone rack server, larger local storage capacity, or GPU acceleration should evaluate alternative form factors.

Questions about this item

What memory upgrades will the M640 blade need later and how many DIMM slots are free?

The blade has 16 DDR4 slots total and ships with 16 GB installed, leaving 14 slots open for future expansion up to the 1.5 TB maximum.

Which component hits its limit first when the dual Xeon Gold 6154 processors run sustained heavy workloads?

The two CPUs top out at 56 combined cores and 3.7 GHz turbo, so compute throughput plateaus before the 1.5 TB memory ceiling or the S140 storage controller are saturated.

How much heat and noise does the half-height blade add to the M1000e or MX chassis when it runs all day?

The blade itself has no integrated fans; cooling and acoustic output depend entirely on the shared chassis fans and power supplies, which vary by enclosure configuration.
