DELL PowerEdge M640 Blade Server 2x Xeon Gold 6150 18-Core 2.7GHz 512GB DDR4 2x 1.92TB NVMe

Half-height blade server for dense compute

The Dell PowerEdge M640 is a half-height blade server built for virtualization, private cloud and high-performance computing workloads. Two Xeon Gold 6150 processors provide 18 cores each at 2.7 GHz with a 3.7 GHz turbo frequency. 512 GB of DDR4 2666 MHz registered ECC memory fills 16 slots and supports up to 1.5 TB total. Dual 1.92 TB NVMe SSDs connect through the PERC S140 controller with RAID 0, 1, 5 and 10 support. A Broadcom 57810S-K dual-port 10 Gb network daughter card and iDRAC9 Enterprise remote management complete the platform.

Upgrade from single-socket or lower-core blades

This configuration replaces single-socket blades or dual-socket systems with fewer cores and less memory capacity. The jump is worth it when workloads demand 36 total cores, large memory footprints and NVMe storage throughput in a single half-height slot. Buyers who need more than two processors or more than 1.5 TB of memory cannot use this blade form factor. Workloads requiring GPU acceleration beyond the integrated Matrox G200 with 8 MB video memory are not suited to this server.

Slide-in installation into MX or M1000e chassis

The blade slides into a compatible PowerEdge MX or M1000e chassis without tools and connects power, networking and management through the midplane. iDRAC9 Enterprise enables remote firmware updates, inventory and power control before the operating system loads. Common issues include forgetting that front bezel and ready rails are not included, mixing memory speeds across the 16 slots, and exceeding the chassis power budget when multiple high-density blades are installed together.
