PowerEdge M640 dual-processor blade

The Dell PowerEdge M640 is a half-height blade server built for dense compute environments. It ships with two Intel Xeon Platinum 8160 processors running at 2.1 GHz with a 3.7 GHz turbo frequency. Each CPU delivers 24 cores, providing substantial parallel processing capacity. The system includes 512 GB of DDR4-2666 registered ECC memory across 16 slots.

Suited for virtualisation and HPC clusters

This blade targets organisations running virtualised workloads, private clouds or high-performance computing tasks that benefit from high core counts and large memory footprints. The integrated PERC S140 controller supports RAID 0, 1, 5 and 10 across two 2.5-inch drive bays. Buyers needing GPU acceleration or more than two 2.5-inch drives should evaluate alternative platforms.

Dual 10 GbE network daughter card installed

A Dell Broadcom 57810S-K dual-port 10 GbE blade network daughter card provides high-speed connectivity within the MX or M1000e chassis. Remote management is handled by iDRAC9 Enterprise for out-of-band administration. The server includes two 2.5-inch SAS/SATA caddies but no operating system, front bezel or ready rails.

Questions about this item

What chassis do I need to install this half-height blade?

It fits the PowerEdge MX and M1000e enclosures, which provide power, cooling and the midplane connections the blade requires.

Will the 10 Gb Broadcom 57810S-K daughter card work with my existing 1 Gb switches?

Yes, the dual-port 10 Gb card auto-negotiates down to 1 Gb so it can link to older switches without replacement.

How do I confirm the 512 GB DDR4 2666 MHz memory is running at full speed after installation?

Open iDRAC9 Enterprise, navigate to the memory inventory page and verify each of the 16 DIMMs shows 2666 MT/s and ECC enabled.
