Blade density and core count

This half-height PowerEdge M640 blade installs two Intel Xeon Gold 6150 processors, each with 18 cores at 2.7 GHz and a 3.7 GHz turbo. The pair delivers up to 56 cores per server in a compact form factor that fits the MX or M1000e chassis.

Virtualisation hosts needing 10 Gb networking

The board includes a Broadcom 57810S-K dual-port 10 Gb daughter card and iDRAC9 Enterprise for remote management, suiting clusters that rely on high-speed fabric and out-of-band control. Buyers who need onboard NVMe RAID or more than two 2.5-inch drive bays should look at a different platform.

Memory ceiling and DDR4 generation

The system ships with 128 GB of DDR4 2666 MHz registered ECC across eight modules and supports a maximum of 2 TB across 16 slots. This capacity and generation determine whether the blade can host the intended workload without a memory upgrade.
