Dell PowerEdge M640 Blade Server

This Dell PowerEdge M640 blade server arrives new with two Xeon Gold 6252 processors running at 2.1 GHz. The unit includes 128GB of DDR4 memory and two 1.8TB SAS hard drives managed by a PERC H330 storage controller. Integrated graphics and a 10GB Ethernet adapter handle display and network duties.

Suited for dense compute clusters needing high

The dual 24-core CPUs deliver strong parallel performance for virtualisation or database workloads within a half-height blade form factor. Buyers who need more than two drives or require GPU acceleration should look at alternative platforms. The fixed two-processor maximum limits future CPU expansion.

128GB DDR4 memory installed across the system board

This capacity uses registered ECC modules compatible with the Xeon Gold 6252 memory controllers. The platform supports up to 1TB total when fully populated with additional DIMMs. Verify the exact DIMM layout against your application requirements before deployment.

Questions about this item

How do I choose between the two installed 1.8 TB SAS drives and adding a second pair?

The blade holds up to two 2.5-inch drives; the 2x 1.8 TB SAS HDDs already fill both bays, so any capacity increase means replacing the existing drives.

What does the 2.1 GHz Xeon Gold 6252 frequency mean when the server is under load?

Each of the two CPUs runs at 2.1 GHz base clock with 24 cores and 35.75 MB cache, delivering consistent multi-threaded throughput for virtualization or database tasks.

How does the PERC H330 SAS controller limit the storage performance?

The PERC H330 provides 12 Gb/s SAS connectivity to the installed 1.8 TB drives, capping sustained throughput at the controller's 12 Gb/s lane speed rather than the drive media rate.
