Dense blade server for virtualised workloads

The Dell PowerEdge M640 is a half-height blade built for high-density compute in MX or M1000e chassis. Two Xeon Platinum 8160 CPUs provide 24 cores each at 2.1 GHz with 3.7 GHz turbo. 512 GB of DDR4 ECC memory fills 16 slots, leaving room to grow toward the 2 TB maximum. Dual 1.92 TB NVMe drives and a PERC S140 controller handle fast local storage.

Suited to consolidation and HPC clusters

This blade fits teams running virtualisation, private cloud or high-performance computing where core density and memory capacity matter. The 10 Gb dual-port daughter card and iDRAC9 Enterprise simplify network and remote management. Buyers who need GPU acceleration, more than two drive bays, or a standalone rack server should look at other form factors.

24 cores per processor at 2.1 GHz base

The decisive specification is the dual 24-core Xeon Platinum 8160 configuration running at 2.1 GHz base with 3.7 GHz turbo. This core count and clock speed define the throughput ceiling for heavily threaded workloads such as database shards, container hosts or simulation nodes.

Questions about this item

How much more DDR4 memory can be added to the 16 slots?

The server has 512GB installed across 16 slots; maximum capacity is 1.5TB so up to 1TB can be added using compatible DDR4 modules

What limits sustained performance first when both Xeon 8160 CPUs run at 3.7GHz turbo?

The blade form factor and shared chassis cooling constrain how long all 24 cores per processor can hold maximum turbo before thermal throttling reduces clocks

What noise and heat output should be expected from this blade running continuously in a populated chassis?

As a half-height blade it relies on the M1000e or MX chassis fans; acoustics and exhaust temperature depend on chassis fan policies and total blade count rather than the server alone
