Purpose-built blade server

The Dell PowerEdge M640 is a dual-processor blade server equipped with two Intel Xeon Bronze 3104 CPUs running at 1.7 GHz. It ships with 256 GB of DDR4 ECC registered memory and a PERC H330 SAS storage controller managing two 300 GB 10K SAS hard drives. Remote administration is handled by iDRAC9 Enterprise and a 10 GbE two-port 562T adapter provides network connectivity.

Suited for dense compute clusters.

This configuration fits environments that need many compute nodes in a shared enclosure, such as virtualisation hosts or HPC worker nodes. The six-core Bronze processors and 256 GB RAM support moderate parallel workloads. Buyers who need more storage bays, higher single-thread performance, or GPU acceleration should evaluate alternative platforms.

Maximum memory ceiling is 1 TB

The system supports up to 1 TB of DDR4 across its DIMM slots, so the installed 256 GB leaves room for expansion. This limit determines whether the blade can grow with future workload demands.

Questions about this item

How does the 256 GB of DDR4 memory perform in a live workload?

The system ships with 256 GB of DDR4 ECC registered memory installed and supports up to 1 TB total, so large datasets stay in memory without swapping.

What does the PERC H330 controller limit in practice?

The PERC H330 RAID controller manages the two 300 GB 10K SAS drives and caps the array at two 2.5-inch bays.

What physical space does the M640 blade occupy?

The blade measures 22 by 22 by 10 inches and weighs 20 units, fitting a standard half-height slot in a compatible chassis.
