Dell PowerEdge M640 Blade Server

The Dell PowerEdge M640 is a half-height blade server configured with two Xeon Platinum 8253 processors running at 2.2 GHz. It includes 256 GB of DDR4 memory and two 4 TB SATA drives managed by a PERC H330 controller. Remote management is handled through iDRAC9 Enterprise.

Suited for dense compute workloads

This blade suits environments that need high core density and integrated 10 Gb Ethernet in a shared enclosure. Buyers who need more storage bays or GPU acceleration should look at alternative platforms.

Dual Xeon Platinum 8253 at 2.2 GHz

The pair of 16-core Xeon Platinum 8253 CPUs delivers 32 cores total at a base frequency of 2.2 GHz. This processor choice determines the threading capacity and power profile for the entire blade.

Questions about this item

Should I choose the 256 GB DDR4 configuration or add more memory up to the 1 TB maximum?

The server ships with 256 GB of DDR4 ECC registered memory installed. The platform supports a maximum of 1 TB, so additional modules can be added later if workloads grow beyond the current capacity.

What does the 2.2 GHz clock speed on the two Xeon Platinum 8253 processors deliver in a real workload?

Each Xeon Platinum 8253 provides 16 cores at 2.2 GHz with 22 MB cache. With two processors installed, the system offers 32 cores total, giving strong multi-threaded throughput for virtualization, databases and compute-intensive tasks.

How does the PERC H330 controller and SATA interface affect the usable speed of the 2.5-inch 4 TB drives?

The PERC H330 SAS controller manages the two 4 TB SATA drives. The SATA link caps each drive at 6 Gb/s, so sustained throughput is limited by the mechanical media rather than the controller or backplane.
