Blade server for dense compute

The Dell PowerEdge M640 blade installs two Xeon Silver 4208 processors at 2.1 GHz with 256 GB of DDR4 memory. Integrated graphics handle basic display output while a PERC H330 SAS controller manages storage. Remote administration uses iDRAC9 Enterprise and a dual-port 10 Gb Ethernet adapter is fitted.

Suits virtualised workloads needing moderate

This configuration supports up to 1 TB of DDR4 and two 2.5-inch drives, so buyers who need more than eight terabytes of local storage or additional drive bays should look elsewhere. Organisations requiring GPU acceleration or fibre-channel connectivity will also need a different platform.

Maximum memory capacity is 1 TB

The installed 256 GB can be expanded to this limit using DDR4 ECC registered modules, which determines how many virtual machines or large datasets the blade can host. If your application demands more memory than 1 TB, this server cannot meet the requirement.

Questions about this item

How do I verify the iDRAC9 Enterprise remote management is responding after the blade is seated in the chassis?

Open a browser to the iDRAC IP address shown on the front LCD, log in with the default credentials, and confirm the System Overview page reports both Xeon Silver 4208 CPUs, 256GB DDR4 memory, and the PERC H330 controller with two 4TB SATA drives online.

Which components ship installed in the M640 blade and which items such as a rail kit must be requested separately?

The blade arrives with two Xeon Silver 4208 processors, 256GB DDR4 ECC registered memory, two 4TB SATA 2.5-inch drives, the PERC H330 RAID controller, and a 10GbE 2-port 562T adapter; the rail kit is not included and is available on request.

Should I select the 256GB DDR4 configuration or plan to expand toward the 1TB maximum for my workload?

Choose 256GB if the current dataset fits comfortably; the board supports up to 1TB of DDR4 ECC registered memory, so additional DIMMs can be added later without replacing the existing modules.
