Blade server for virtualization and HPC

The Dell PowerEdge M640 is a half-height blade built for dense compute in PowerEdge MX or M1000e chassis. Two Intel Xeon Platinum 8160 processors run at 2.1 GHz with a 3.7 GHz turbo frequency. Installed memory is 64 GB of DDR4 across four 16 GB modules, with capacity for up to 1.5 TB total.

Suits dense clusters; not for standalone

This unit targets administrators scaling virtualization, private cloud or high-performance computing inside a supported blade enclosure. It lacks an operating system, front bezel and ready rails. Buyers who need a standalone rack server, dedicated GPU acceleration or more than two 2.5-inch drive bays should evaluate other form factors.

Dual 10 GbE daughter card enables high-throughput

A Dell Broadcom 57810S-K dual-port 10 GbE network daughter card is fitted, providing 10 Gb connectivity per port for east-west traffic and storage networks. The PERC S140 controller handles RAID 0, 1, 5 and 10 on SATA or NVMe drives installed in the two supplied caddies. iDRAC9 Enterprise gives full out-of-band management.

Questions about this item

Will the 64GB DDR4 limit sustained workloads?

The server ships with 64GB DDR4 across 16 slots and supports up to 1.5TB total, so memory can be expanded well beyond the factory configuration.

How do the dual Xeon Platinum 8160 CPUs and 10Gb networking affect heat and power in continuous operation?

Two 24-core Xeon Platinum 8160 processors at 2.1GHz with 3.7GHz turbo and a dual-port 10Gb Broadcom 57810S-K network card will draw significant power and generate heat that must be managed by the chassis cooling system.

What chassis and power infrastructure must already be in place for this half-height blade?

The M640 blade requires a compatible PowerEdge MX or M1000e chassis with available half-height slots, chassis power supplies and cooling fans to operate.
