Dell PowerEdge M640 Blade Server

The Dell PowerEdge M640 is a dual-socket blade server built for dense compute workloads. It ships with two Intel Xeon 5118 processors running at 2.3 GHz and 12 cores each. A total of 256 GB of DDR4 ECC registered memory is installed across the available slots. Storage is handled by a PERC H330 controller with two 300 GB 10K SAS 2.5-inch drives.

Suited for virtualisation clusters

This configuration fits environments that need high core counts and large memory capacity in a blade form factor. The two installed drives provide limited local storage, so buyers who want more storage or all-flash arrays should look at other configurations. Workloads requiring dedicated GPU acceleration are not supported by the integrated graphics.

Dual Xeon 5118 processors with 256 GB DDR4

The pair of 12-core Xeon 5118 CPUs and 256 GB of DDR4 memory define the performance ceiling for compute-heavy tasks. Memory can be expanded up to the platform maximum of 1 TB if the workload grows. The PERC H330 controller and SAS interface determine which drive upgrades are possible.

Questions about this item

What chassis slot size does the 22 x 22 x 10 in blade occupy?

The blade measures 22 by 22 by 10 inches and weighs 20 units, so it requires a half-height slot in a compatible Dell blade enclosure.

Which step is often missed when seating the PERC H330 controller with the 2x 300GB SAS drives?

The PERC H330 RAID controller must be fully seated in its dedicated mezzanine slot and the SAS cables secured before the blade is locked into the enclosure, otherwise the drives will not be detected.

When should the 256GB DDR4 ECC registered memory be upgraded toward the 1TB maximum?

Add DDR4 ECC registered modules in matched pairs when workloads exceed the installed 256GB capacity, up to the 1TB limit supported by the two Xeon 5118 processors.
