DELL PowerEdge M640 blade server 2× Xeon Gold 6154 3.0 GHz 18C 64GB DDR4 H330 57810S-K iDRAC9 Enterprise

Dual-socket Xeon Gold 6154 blade

The Dell PowerEdge M640 is a half-height blade server built around two Intel Xeon Gold 6154 processors running at 3.0 GHz with 3.7 GHz turbo. Eighteen cores per socket give 36 threads total, supported by 64 GB of DDR4 2666 MHz registered ECC memory across four DIMMs. A PERC H330 controller and two 2.5-inch drive caddies handle local storage, while a Broadcom 57810S-K daughter card provides dual-port 10 Gb Ethernet. iDRAC 9 Enterprise enables full remote management.

Suits virtualisation hosts needing dense compute

This blade fits organisations running virtualised workloads, private cloud or HPC clusters that benefit from high core counts in a compact chassis. It suits teams already standardised on Dell M1000e or PowerEdge MX enclosures with available half-height slots. Buyers who need internal GPU acceleration or more than two drive bays should evaluate other platforms. Workloads requiring larger local memory footprints will need additional DIMMs up to the 1.5 TB limit.

Two-socket 18-core limit defines scaling ceiling

The server is factory-limited to two processors, so the 36 combined cores represent the hard ceiling for this blade. Memory scales to 1.5 TB across 16 slots, but CPU expansion stops at the installed pair. Planning must account for this fixed boundary when sizing clusters or licensing per-core software.
