Blade Server for Virtualisation and HPC

The Dell PowerEdge M640 is a half-height blade server built for dense compute workloads such as virtualisation, private cloud and high-performance computing. Two Intel Xeon Gold 6230 processors deliver 20 cores each at 2.1 GHz with 3.9 GHz turbo. 32 GB of DDR4 2666 MHz registered ECC memory is installed across 16 slots.

Best for Scale-Out Deployments in MX

Suits teams that need high core density in a shared chassis with 10 Gb dual-port networking and iDRAC9 Enterprise management. Not suited for buyers who need GPU acceleration, local NVMe boot drives, or a standalone tower or rackmount form factor.

Dual 20-Core Xeon Gold 6230 CPUs

The server ships with two 20-core Intel Xeon Gold 6230 processors, giving 40 cores total in a single blade. This core count determines whether the node meets the licensing or throughput targets of the intended workload.

Questions about this item

What does the 3.9 GHz turbo on the Xeon Gold 6230 mean when the blade is fully loaded?

Each of the 20 cores per processor can reach 3.9 GHz for short bursts, but sustained all-core speeds will drop toward the 2.1 GHz base under heavy multi-threaded workloads.

How does the S140 controller limit the installed 1.92 TB SATA SSDs?

The S140 handles SATA at 6 Gb/s and provides RAID 0, 1, 5, 10, but does not support NVMe, so the drives run at SATA speeds with software-assisted RAID.

What chassis slot and width does this half-height blade need?

It fits one half-height bay in a PowerEdge MX or M1000e chassis and uses the 2.5-inch drive form factor for its two installed SSDs.
