Blade compute density

The Dell PowerEdge M640 is a half-height blade server fitted with two Intel Xeon Gold 6230 processors running at 2.10 GHz with a 3.9 GHz turbo frequency. Each CPU provides 20 cores for a total of 40 threads across the blade. The system ships with 128 GB of DDR4 2666 MHz registered ECC memory installed in eight of sixteen slots. It is intended for virtualization, private cloud and high-performance computing workloads that demand high core counts in a compact chassis slot.

Thermal and power profile

As a blade, the M640 relies on the shared cooling infrastructure of a PowerEdge MX or M1000e enclosure rather than onboard fans. The dual 20-core Xeon Gold 6230 processors have a combined thermal design that the chassis must dissipate under load. Power draw scales with CPU utilisation and the installed SATA SSDs, but the blade form factor concentrates heat in a dense 2.5-inch footprint. Acoustic output is determined by the enclosure fans and will vary with inlet temperature and workload intensity.

Integrated management and networking

The server includes a Broadcom 57810S-K dual-port 10 Gb network daughter card for high-speed fabric connectivity. iDRAC9 Enterprise provides out-of-band remote management with full lifecycle automation and monitoring. The PERC S140 controller manages the two 960 GB SATA SSDs with support for RAID 0, 1, 5 and 10 configurations. No operating system, front bezel or ready rails are included; the blade is designed for direct insertion into a compatible Dell chassis.

Questions about this item

How do I install this blade server into a PowerEdge MX or M1000e chassis, and what step is often missed?

Slide the half-height blade into an empty bay until the latch clicks, then use the iDRAC9 Enterprise interface to inventory the server; the step often missed is confirming the Broadcom 57810S-K 10Gb daughter card is seated before powering on.

What maintenance will the 960GB SATA SSDs and DDR4 memory need over time?

Monitor SSD wear via the PERC S140 controller and replace drives when SMART indicators approach end-of-life; DDR4 ECC modules require no scheduled replacement but should be reseated if correctable error counts rise.

What thermal or power limit appears first when both Xeon Gold 6230 CPUs run at 3.9GHz turbo under sustained load?

The blade's shared chassis cooling and power budget typically cap combined CPU turbo before individual processor thermal limits are reached, throttling frequencies to stay within the enclosure's design envelope.
