Dense compute blade for virtualization and HPC

The PowerEdge M640 is a half-height blade server built for dense deployments in PowerEdge MX or M1000e chassis. It arrives with two Intel Xeon Gold 6150 processors, each delivering 18 cores at 2.7 GHz with a 3.7 GHz turbo frequency. Sixteen gigabytes of DDR4 2666 MHz registered ECC memory are installed across two modules, leaving 14 slots open for expansion up to the platform maximum. Two 1.92 TB SATA SSDs provide primary storage managed by the integrated PERC S140 controller.

Shared chassis cooling and 10 Gb networking

Thermal management relies on the enclosing chassis fans, so the blade itself adds no independent noise source and draws power through the mid-plane. The PERC S140 handles RAID 0, 1, 5 and 10 across SATA or SAS devices, while the installed SATA SSDs operate at 6 Gb/s. A Broadcom 57810S-K dual-port 10 Gb daughter card supplies high-throughput networking without consuming a PCIe slot. iDRAC9 Enterprise enables remote power, console and firmware control over a dedicated management network.

Scales within the same blade enclosure

This unit suits teams expanding an existing MX or M1000e environment who need more cores and fast local storage without adding rack height. The dual-socket configuration maxes out the blade at 36 cores and 2 TB of DDR4, so workloads that outgrow that ceiling will require additional blades or a different form factor. Buyers needing GPU acceleration, Fibre Channel connectivity or front-accessible drive bays should look elsewhere, as the M640 provides none of those.

Questions about this item

How do I install the M640 blade into a PowerEdge MX or M1000e chassis, and what step is commonly missed?

Slide the half-height blade into an empty bay until the latch clicks, then use iDRAC9 Enterprise to inventory the 2x Xeon Gold 6150 CPUs and 16GB DDR4; the step often missed is enabling the 57810S-K 10Gb daughter card in the chassis I/O fabric before first boot.

What maintenance or replacement will the PERC S140 storage controller and 1.92TB SSDs need over time?

Monitor SSD wear via iDRAC9; replace a 1.92TB SATA drive when SMART reports exhausted write cycles, and keep PERC S140 firmware current to maintain RAID 0/1/5/10 integrity across both 2.5-inch bays.

What thermal or power limit appears first when both 18-core 2.7GHz CPUs run at 3.7GHz turbo under sustained load?

The half-height blade form factor and shared chassis cooling cap sustained turbo; iDRAC9 will throttle the 2x Xeon Gold 6150 processors before the 16GB DDR4 or PERC S140 become bottlenecks.
