DELL PowerEdge M640 Blade Server

The DELL PowerEdge M640 is a blade server system built for dense compute environments. It arrives new with two Intel Xeon Gold 6140 processors running at 2.3 GHz, each delivering 18 cores. The system includes 256 GB of DDR4 ECC registered memory and a PERC H330 SAS storage controller managing two 300 GB 10K SAS drives. Integrated graphics and an iDRAC9 Enterprise module provide out-of-band management.

Ideal for virtualisation clusters

This configuration suits teams that need high core counts and large memory capacity in a half-height blade form factor. The two installed 300 GB SAS drives offer limited local capacity, so buyers who want more storage or all-flash arrays should look at something else. Workloads that require dedicated GPU acceleration are not addressed by the integrated graphics.

Dual Xeon Gold 6140 at 2.3 GHz with 18 cores each

The defining specification is the pair of Xeon Gold 6140 CPUs, each running at 2.3 GHz with 18 cores and 24.75 MB cache. This processor choice sets the performance ceiling for the blade and determines licensing costs for many hypervisors. Confirm that your software stack and chassis power budget align with this dual-socket design before purchase.

Questions about this item

Does the blade ship with rails or do I need to order them separately?

The rail kit is available on request and is not included by default.

Should I pick the 300 GB SAS drives or a larger capacity for this M640?

The chassis supports up to two 2.5" drives; the installed 300 GB 10K SAS pair fills both bays.

What does the 2.3 GHz clock on the Xeon Gold 6140 mean for real workloads?

Each of the two 18-core CPUs runs at 2.3 GHz base frequency with 24.75 MB cache for consistent multi-threaded performance.
