Blade Server System

The Dell PowerEdge M640 is a blade-format server system fitted with two Intel Xeon Silver 4112 processors running at 2.6 GHz. It arrives with 256 GB of DDR4 ECC registered memory and a PERC H330 SAS storage controller managing two 1.8 TB SAS hard drives. Integrated graphics and an iDRAC9 Enterprise remote management module are included.

Density-Focused Compute

This configuration suits operators who need high processor density in a standard blade envelope and can work within the installed 256 GB memory ceiling. Buyers who require more than 256 GB of RAM or who need additional drive bays beyond the two 2.5-inch slots should look at alternative chassis designs.

Dual-Socket Silver 4112

The decisive specification is the pair of Xeon Silver 4112 CPUs, each delivering four cores at 2.6 GHz with 8.25 MB cache, which fixes the thread count and per-core performance envelope for every workload placed on this blade.

Questions about this item

How do I slide the M640 blade into the enclosure and lock it in place?

Align the blade rails with the enclosure guides, push until the connector seats, then tighten the two captive thumb-screws on the front latch — skipping the screws leaves the blade loose and causes boot failures.

What components will need replacement after several years of continuous operation?

The two 1.8 TB SAS hard drives and the system cooling fans are the primary field-replaceable units; DDR4 memory and the PERC H330 controller rarely require service.

What thermal limit appears first when both Xeon Silver 4112 CPUs run at 2.6 GHz under sustained load?

The blade’s internal temperature sensors trigger throttling once the chassis inlet air exceeds the enclosure’s specified maximum, reducing CPU frequency to protect the 256 GB DDR4 memory and 2.5" drives.
