Dual-socket Xeon Gold 6230 blade server

The Dell PowerEdge M640 is a half-height blade server that fits into PowerEdge MX or M1000e chassis. Two Intel Xeon Gold 6230 processors provide 20 cores each at a base frequency of 2.10 GHz with a 3.9 GHz turbo. The system ships with 32 GB of DDR4 2666 MHz registered ECC memory across 16 slots and a Dell PERC S140 storage controller.

Suited for virtualisation clusters needing dense

This blade targets workloads such as virtualization, private cloud and high-performance computing where two-socket density in a single half-height slot is required. The 2.5-inch drive bays accept SATA or SAS media and the Broadcom 57810S-K card supplies dual 10 Gb networking. Buyers who need more than two processors, larger local storage capacity, or a rack-mount tower form factor should evaluate other platforms.

Max memory capacity of 1.5 TB across 16 DDR4 slots

The motherboard supports up to 1.5 TB of DDR4 registered ECC memory using all 16 DIMM slots. The installed 32 GB (4 × 8 GB) configuration leaves headroom for substantial expansion. Confirm that your chassis provides adequate cooling and power budget for the target memory population before ordering additional modules.

Questions about this item

What chassis and bay size does this half-height blade require?

It fits a Dell PowerEdge MX or M1000e chassis and occupies a single half-height blade slot with two 2.5-inch drive bays.

How is the blade installed, and what step is often missed?

Slide the blade into the chassis until the latch engages, then attach the bezel; the bezel is not included and must be sourced separately.

Which memory modules will need replacement when expanding beyond the installed 32 GB?

The server holds 16 DDR4 slots; four 8 GB modules are installed, so additional DDR4 registered ECC DIMMs are added to the remaining slots.
