Dell PowerEdge M640 Blade Server

This Dell PowerEdge M640 blade server delivers dual Intel Xeon Gold 6240 processors, each running at 2.60 GHz with 18 cores. It arrives with 256 GB of DDR4 ECC registered memory installed, expandable to 1 TB. The chassis supports up to two 2.5-inch drives and includes a PERC H330 SAS storage controller. Remote management is handled by iDRAC9 Enterprise.

Ideal for dense virtualisation

The two-socket design suits organisations consolidating virtual machines or running memory-intensive databases within a standard blade enclosure. Integrated graphics and 10 GbE networking cover basic display and connectivity needs. Buyers who need more than two internal drives, GPU acceleration, or storage interfaces other than SAS should evaluate alternative platforms.

Dual Xeon Gold 6240 CPUs with 18 cores each

The processor count and core density define the server's parallel throughput ceiling. With 36 total cores at 2.60 GHz, the system targets heavily threaded applications that fit within the 256 GB memory footprint. Confirm that your workload fits the two-drive SAS limit and the blade form factor before purchase.

Questions about this item

How does the 256 GB DDR4 memory perform once the M640 blade is running live workloads?

The blade ships with 256 GB of DDR4 ECC registered memory installed across its DIMM slots, leaving room to expand up to 1 TB if your applications need more capacity.

What does the PERC H330 controller limit when using the two 1.8 TB SAS drives?

The PERC H330 handles RAID 0, 1, 5, 10 and JBOD on SAS links, so the drive pair can be mirrored for redundancy or striped for combined capacity.

What physical space must be free in the chassis for this M640 blade to seat correctly?

The module measures 22 x 22 x 10 inches and weighs 20 lb, so the enclosure bay must accommodate those dimensions and weight.
