Dense compute blade for virtualization and HPC

The Dell PowerEdge M640 half-height blade fits the MX or M1000e chassis and ships with two Xeon Gold 6230 processors, each 20 cores at 2.1 GHz with 3.9 GHz turbo. 128 GB of DDR4-2666 registered ECC memory occupies eight of the 16 slots, leaving room to reach the 1.5 TB platform ceiling. A PERC S140 controller manages the two installed 1.92 TB SATA SSDs in RAID 0, 1, 5 or 10, while a Broadcom 57810S-K card adds dual 10 Gb network ports and iDRAC9 Enterprise handles remote management.

Suited for scale-out clusters needing maximum

Buyers who want more storage bays, GPU acceleration, or a stand-alone tower or rack-mount server should look elsewhere. The blade form factor requires a compatible Dell chassis for power, cooling and fabric interconnects, so sites without an MX or M1000e enclosure cannot deploy this unit.

Dual 20-core Xeon Gold 6230 CPUs set

Forty total cores and 128 GB of DDR4 define the throughput ceiling for virtualization, private cloud or HPC workloads. Memory can be expanded to 1.5 TB using the remaining eight slots, and the S140 controller supports additional SATA or SAS drives within the two 2.5-inch bays.

Questions about this item

How loud and hot does the M640 get when the dual Xeon Gold 6230 CPUs run at full load all day?

The blade uses the chassis fans and shared cooling of the M1000e or MX enclosure; the two 20-core Xeon Gold 6230 processors have a base speed of 2.1 GHz and can turbo to 3.9 GHz, so sustained heat and noise depend on the enclosure configuration.

What must I already own for this blade to operate?

It requires a Dell PowerEdge M1000e or MX series chassis that accepts half-height blades, plus compatible power supplies and I/O fabric modules for the Broadcom 57810S-K 10 Gb dual-port daughter card.

Will my existing DDR4 RDIMMs work alongside the installed 128 GB in the 16 memory slots?

The server has 16 DDR4 slots supporting up to 1.5 TB total; the installed 128 GB uses eight 16 GB modules at 2666 MHz, so matching RDIMMs of the same speed and rank can be added to the remaining slots.
