Blade server for dense compute

The Dell PowerEdge M640 is a half-height blade server that fits into PowerEdge MX or M1000e chassis. It ships with two Intel Xeon Gold 6154 processors running at 3.0 GHz with a 3.7 GHz turbo, each providing 18 cores for a total of 36 cores. The system includes 64 GB of DDR4 2666 MHz registered ECC memory across four 16 GB modules. It is suited for virtualization, private cloud and high-performance computing workloads.

Storage controller and network card

The integrated Dell PERC S140 controller supports SATA and NVMe drives with RAID 0, 1, 5 and 10. Two 2.5-inch SAS/SATA drive caddies are included for internal storage. A Broadcom 57810S-K dual-port 10 Gb network daughter card provides high-speed connectivity. iDRAC9 Enterprise enables remote management and automation. No operating system, front bezel or ready rails are included.

Half-height blade form factor

This server requires a compatible PowerEdge MX or M1000e blade enclosure for power, cooling and fabric interconnects. It will not operate as a standalone rack or tower unit. Maximum memory capacity is 1.5 TB across 16 DDR4 slots, allowing future expansion. Buyers who need a self-contained rack server or a tower chassis should consider a different form factor.

Questions sur cet article

How much memory can I add to the 16 DDR4 slots beyond the 64 GB installed?

The board supports up to 1.5 TB of DDR4 2666 MHz registered ECC memory across the 16 slots.

Which component will hit its ceiling first when the two 18-core Xeon Gold 6154 CPUs run at 3.7 GHz turbo continuously?

The 3.7 GHz turbo frequency is the limit that appears first under sustained all-core load.

What noise and heat should I expect from the blade running all day in a populated chassis?

The blade relies on the M1000e or MX chassis fans; its dual 10 Gb network card and Matrox G200 GPU add minimal extra heat.
