Dell PowerEdge M640 Blade Server

The Dell PowerEdge M640 is a dual-socket blade server built for dense compute environments. It ships with two Intel Xeon Bronze 3204 processors running at 1.90 GHz and 384 GB of DDR4 ECC registered memory. The system includes a PERC H330 SAS storage controller and integrated graphics for management console output. Remote administration is handled by iDRAC9 Enterprise.

Suited for virtualisation hosts needing high

This configuration fits workloads that prioritise RAM over raw CPU frequency, such as virtual desktop infrastructure or in-memory databases. The six-core Bronze 3204 CPUs limit single-thread performance, so latency-sensitive applications or heavy calculation tasks should look at higher-frequency or higher-core-count alternatives. The two installed 900 GB SAS drives provide a fixed starting capacity for the operating system and local scratch space.

Maximum memory capacity of 1 TB

The chassis supports up to 1 TB of DDR4 across its DIMM slots, leaving headroom beyond the 384 GB currently installed. This ceiling determines whether the blade can grow with your dataset or if a larger platform is required. The PERC H330 controller manages the two 2.5-inch SAS bays in RAID 0, 1 or JBOD modes. Network connectivity uses a dual-port 10 GbE 562T adapter.

Questions about this item

What enclosure slot size does the M640 blade require?

The M640 is a half-height blade that fits a single half-height bay in a compatible Dell enclosure.

What must be done before the PERC H330 controller can present the two 900 GB SAS drives to the operating system?

Use the controller BIOS or iDRAC9 to create a virtual disk from the installed drives; the array is not pre-configured.

Which component uses the DDR4 memory type installed in this server?

The 384 GB of installed memory is DDR4 ECC registered DIMMs; any future upgrades must match that type.
