Half-height blade server for dense compute

The Dell PowerEdge M640 is a half-height blade server built for virtualisation, private cloud and high-performance computing workloads. Two Intel Xeon Gold 6154 processors deliver 36 cores at 3.0 GHz with 3.7 GHz turbo. Sixty-four gigabytes of DDR4-2666 registered ECC memory and two 1.92 TB SATA SSDs provide fast data access. iDRAC9 Enterprise enables remote management.

Verify chassis, cooling and network fabric

Confirm the blade fits a compatible PowerEdge MX or M1000e enclosure with adequate power and cooling capacity. Ensure the chassis backplane supports the installed Broadcom 57810S-K 10 Gb dual-port daughter card. Check that the PERC S140 controller meets your RAID requirements for the two 2.5-inch drives. No operating system is included.

Replaces older half-height blades when core

This configuration upgrades from earlier half-height blades that max out at lower core counts or lack 10 Gb networking. The jump is worth it when you need 36 cores and 64 GB in a single slot without moving to full-height form factors. It does not suit buyers who require GPU acceleration, larger local storage arrays or full-height expansion slots.

Questions about this item

What comes in the box and what must be purchased separately?

The blade ships with two Xeon Gold 6154 processors, 64 GB DDR4 memory, two 1.92 TB SATA SSDs, a PERC S140 controller, a Broadcom 57810S-K 10 Gb dual-port daughter card and iDRAC9 Enterprise. Front bezel, ready rails, an operating system and a compatible MX or M1000e chassis are not included.

Which memory configuration should I choose for this blade?

The system has 16 DDR4 slots and currently holds four 16 GB modules at 2666 MHz. You can add up to 1.5 TB total using registered ECC DDR4 DIMMs.

What does the 3.0 GHz base clock mean in daily use?

Each of the 18 cores runs at 3.0 GHz and can boost to 3.7 GHz under load, giving 36 threads total for virtualization, cloud or compute workloads.
