Dual 18-core Xeon Gold blade server

The Dell EMC PowerEdge M640 is a half-height blade server fitted with two Intel Xeon Gold 6154 processors. Each CPU runs at 3.0 GHz with a 3.7 GHz turbo and provides 18 cores for a total of 36 cores. The system ships with 128 GB of DDR4 2666 MHz registered ECC memory across eight modules. It is designed for dense compute workloads in MX or M1000e chassis.

Upgrades from single-socket or lower-core blades

Replacing an older single-socket blade or a dual-socket model with fewer than 18 cores per CPU yields a substantial jump in thread count and memory bandwidth. The integrated PERC S140 controller adds native NVMe and SATA RAID 0, 1, 5 and 10 support for the two 2.5-inch drive bays. The move is worth it when virtualization density or HPC throughput must increase within the same chassis slot.

Suited for virtualization clusters and HPC nodes

This blade fits organisations expanding a PowerEdge MX or M1000e environment that need maximum core density per half-height slot and 10 Gb dual-port connectivity via the Broadcom 57810S-K daughter card. Buyers who require GPU acceleration, fibre-channel networking, or more than two drive bays should look at full-height or accelerator-optimised alternatives.

Questions about this item

Which chassis will this half-height blade server fit into?

The PowerEdge M640 is a half-height blade that installs in a PowerEdge MX or M1000e enclosure.

How do I install the 2.5-inch drive caddies, and what step is often missed?

Slide each caddy into the front drive bay until it clicks; the common mistake is not locking the release lever, leaving the drive unsecured.

What memory upgrades will this server need later, and how many slots are free?

It uses DDR4 2666 MHz registered ECC DIMMs across 16 slots; 8 slots are occupied by the 128 GB kit, leaving 8 slots for expansion up to 2 TB.
