Blade density for compute-heavy workloads

The Dell PowerEdge M640 is a half-height blade server built for the M1000e or PowerEdge MX chassis. It ships with two Intel Xeon Gold 6150 processors, each running 18 cores at 2.7 GHz with a 3.7 GHz turbo frequency. The system includes 32 GB of DDR4 ECC memory across four modules and a PERC S140 controller managing two 1.92 TB SATA SSDs in a 2.5-inch form factor.

Suited for virtualisation clusters, not GPU farms

This blade targets organisations running dense virtualisation, private cloud or high-performance compute jobs that scale across many nodes. The dual 18-core CPUs and 10 Gb dual-port networking give strong throughput per rack unit. Buyers needing local GPU acceleration, large local storage arrays or workloads that exceed the two-socket limit should evaluate alternative platforms.

Memory headroom to 2 TB with room to grow

The installed 32 GB uses four of sixteen DDR4 slots, leaving capacity for significant expansion up to the 2 TB maximum. The two 1.92 TB SSDs provide fast boot and application storage with RAID 0, 1, 5 or 10 options via the S140 controller. Additional drive bays are not present in this two-bay configuration, so capacity scaling relies on shared storage or chassis-level resources.

Questions about this item

Does the M640 blade require a PowerEdge MX or M1000e chassis to operate?

Yes, the half-height blade must be installed in a compatible PowerEdge MX or M1000e chassis that provides power, cooling and the backplane interconnects.

Will the installed PERC S140 controller recognise my existing 2.5-inch SAS hard drives?

The S140 supports SATA and SAS interfaces, so 2.5-inch SAS drives can be used in the two front bays alongside the factory SSDs.

How can I confirm the dual Xeon Gold 6150 processors are running at their 3.7 GHz turbo frequency?

Use the iDRAC9 Enterprise interface or BIOS to monitor real-time CPU clock speeds and verify turbo engagement under load.
