Dual-Socket Blade Server

The Dell PowerEdge M640 is a half-height blade server built around two Intel Xeon Gold 6230 processors. Each CPU runs at 2.1 GHz with a 3.9 GHz turbo frequency and provides 20 cores, giving 40 cores total in a single blade. It ships with 16 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots.

Virtualisation Hosts Not Storage Arrays

This blade suits teams running virtualisation, private cloud or high-performance compute inside a PowerEdge MX or M1000e chassis. Buyers who need local NVMe capacity beyond the two 2.5-inch bays or who require a GPU for accelerated workloads should look at a different platform. The integrated Matrox G200 graphics only covers basic console output.

Chassis Dependent Compute Node

The M640 installs directly into a supported Dell blade enclosure which supplies power, cooling and fabric interconnects. The PERC S140 controller manages SATA or NVMe drives in the two front-accessible trays while the Broadcom 57810S-K daughter card delivers dual 10 Gb Ethernet connectivity. iDRAC9 Enterprise provides full out-of-band management without consuming a front-panel port.

Questions about this item

Does this blade need a Dell PowerEdge MX or M1000e chassis to operate?

Yes, the M640 is a half-height blade that must be installed in a compatible Dell PowerEdge MX or M1000e chassis for power, cooling and fabric connectivity.

Will the Broadcom 57810S-K 10Gb dual-port card work with my existing 1Gb switches?

The 57810S-K supports 10Gb speeds and is generally backward compatible with 1Gb Ethernet when connected via appropriate copper or fibre cabling and switch ports.

How do I confirm the iDRAC9 Enterprise features are active after the blade is seated?

Open a browser to the iDRAC IP address, log in, and verify the licence page shows Enterprise entitlements such as virtual console, remote file share and telemetry streaming.
