Dell PowerEdge M640 blade server

This half-height blade server fits into PowerEdge MX and M1000e chassis for high-density deployments. Two Intel Xeon Platinum 8160 processors deliver 24 cores each at 2.1 GHz with a 3.7 GHz turbo frequency. The system includes 512 GB of DDR4 registered ECC memory across 16 slots and a PERC S140 storage controller.

Suited for virtualisation

The 512 GB memory capacity and dual 24-core CPUs handle dense virtual-machine hosting and high-performance computing tasks. The 10 Gb dual-port network daughter card provides high-throughput connectivity. Buyers who need GPU acceleration or more than two 2.5-inch drive bays should look at alternative platforms.

512 GB DDR4 registered ECC memory

The installed 16× 32 GB modules run at 2666 MHz and fill all 16 DIMM slots, leaving no room for expansion without removing existing sticks. Maximum supported capacity is 2 TB, so future growth requires replacing the current configuration.

Questions about this item

How do I install the blade into an MX or M1000e chassis, and what step is often missed?

Slide the half-height blade into an empty bay until the latch clicks, then attach the 57810S-K 10 Gb dual-port daughter card so the server gets network connectivity.

Which components will need replacement first during the server's life?

The two 960 GB SATA SSDs and the 512 GB DDR4 2666 MHz registered ECC DIMMs are the only field-replaceable parts that wear out.

What limit appears first when the CPUs run at 3.7 GHz turbo continuously?

The dual Xeon Platinum 8160 24-core processors hit their thermal ceiling before the 2 TB memory ceiling or the PERC S140 storage bandwidth.
