Dense compute blade for scale-out workloads

The Dell PowerEdge M640 is a half-height blade server built for high-density environments. Two Intel Xeon Gold 6150 processors provide 36 cores at 2.7 GHz with 3.7 GHz turbo, targeting virtualization, private cloud and HPC clusters. iDRAC9 Enterprise enables remote lifecycle management across the chassis.

Suits teams expanding within MX or M1000e enclosures

Organisations already running compatible Dell chassis can add compute without new infrastructure. The blade supports SATA and NVMe drives through the integrated PERC S140 controller with RAID 0/1/5/10. Buyers needing GPU acceleration, fibre-channel connectivity or more than two processor sockets should evaluate alternative form factors.

32 GB DDR4 installed with room to grow

Four 8 GB registered ECC modules occupy four of sixteen slots, leaving headroom toward the 2 TB maximum. The dual 10 Gb Broadcom 57810S ports handle east-west traffic for clustered workloads. Storage capacity is limited to two 2.5-inch bays, so datasets exceeding local space require external arrays or shared storage.

Questions about this item

Which chassis do I need to mount this half-height blade server?

The M640 fits the PowerEdge MX and M1000e chassis; it requires one half-height slot in either enclosure.

Can I keep my existing DDR4 2666 MHz registered ECC modules when expanding memory?

Yes, the server has 16 DDR4 slots supporting up to 1.5 TB, so matching 2666 MHz registered ECC DIMMs can be added alongside the installed 32 GB.

How do I confirm the 10 Gb dual-port network daughter card is active after installation?

Check iDRAC9 Enterprise inventory and the OS network adapters; both 10 Gb ports on the Broadcom 57810S-K should appear linked and passing traffic.
