Blade server for virtualisation and HPC

The Dell EMC PowerEdge M640 is a half-height blade server built for dense compute in PowerEdge MX or M1000e chassis. Two Intel Xeon Gold 6154 processors provide 36 cores at 3.0 GHz with 3.7 GHz turbo, and 512 GB of DDR4 2666 MHz registered ECC memory fills all 16 slots. A PERC H330 controller manages two 1.92 TB SAS SSDs in RAID 0, 1, 5, 10 or 50, while a Broadcom 57810S-K daughter card supplies dual 10 Gb network ports and iDRAC9 Enterprise handles remote management.

Suits dense compute clusters.

This blade fits organisations that need high core counts and large memory in a shared chassis for virtualisation, private cloud or high-performance computing workloads. Buyers who require GPU acceleration, front-accessible NVMe bays, or a standalone rack-mount form factor should consider other platforms. The installed Matrox G200 graphics provides only basic console output, and the H330 controller does not support NVMe drive arrays.

Dual 10 Gb network daughter card decides fabric fit

The Broadcom 57810S-K 10Gb dual-port blade network daughter card is the single specification that determines whether this server matches the existing chassis fabric. If the infrastructure runs 10 Gb Ethernet uplinks, the card integrates directly; if the fabric uses a different speed or protocol, a compatible daughter card must be sourced separately.

Questions about this item

Which chassis does the M640 blade fit into?

The half-height blade installs in a PowerEdge MX or M1000e enclosure that provides power, cooling and fabric interconnects.

How do I install the two Xeon Gold 6154 processors into the LGA 3647 sockets?

Align each CPU with the socket keying, lower the load plate gently, and torque the retention screws in the labelled cross pattern to avoid uneven pressure.

When should the 1.92TB SAS SSDs or the H330 controller battery be replaced?

Monitor SSD wear via iDRAC9 Enterprise and swap drives before the rated endurance is exhausted; replace the controller cache battery when the health status reports degradation.
