High-Density Blade Server

The Dell PowerEdge M640 is a half-height blade server built for dense data-centre deployments. It targets organisations running virtualisation, private-cloud or high-performance-computing workloads that need maximum compute per rack unit. The platform fits inside PowerEdge MX and M1000e chassis for consolidated management.

Dual 18-Core Xeon Gold 6150 CPUs

Two Intel Xeon Gold 6150 processors provide 36 total cores at a 2.70 GHz base clock with 3.7 GHz turbo capability. The LGA 3647 socket pair represents the maximum processor count for this blade, so no further CPU expansion is possible. Each chip delivers 18 cores for heavily threaded applications.

Blade Installation With Chassis Dependency

Mounting the M640 requires a compatible PowerEdge MX or M1000e enclosure with available half-height slots and matching fabric modules. The blade ships without front bezel or ready rails, so those must be sourced from the chassis kit. Network connectivity depends on the installed Broadcom 57810S-K 10Gb dual-port daughter card aligning with the chassis I/O fabric. iDRAC9 Enterprise enables remote setup once the blade is seated and powered.
