Half-height blade server for dense compute

The Dell PowerEdge M640 is a half-height blade server built for high-density data centre racks. Two Intel Xeon Gold 6154 processors deliver 18 cores each at 3.0 GHz with 3.7 GHz turbo. 128 GB of DDR4 2666 MHz registered ECC memory and two 960 GB SATA SSDs are installed. The PERC S140 controller supports RAID 0, 1, 5 and 10.

Virtualisation and HPC clusters.

This blade suits virtualisation hosts, private cloud nodes and high-performance computing clusters that need many cores in a small footprint. The integrated Matrox G200 graphics with 8 MB video memory cannot drive GPU-accelerated workloads or visualisation tasks. Buyers who need GPU compute or local NVMe boot drives should evaluate other platforms.

Dual 10 Gb network daughter card for fabric

The Dell Broadcom 57810S-K dual-port 10 Gb blade network daughter card provides the primary fabric uplink. iDRAC9 Enterprise enables full remote management and automation. No operating system is included and front bezel with ready rails are not supplied.

Questions about this item

What memory upgrades will this blade need later?

It has 8 of 16 DDR4 slots filled with 16 GB modules at 2666 MHz; you can add up to 1.5 TB total using registered ECC DDR4

Which component hits its limit first under sustained load?

The two 960 GB SATA SSDs on the PERC S140 controller will saturate at 6 Gb/s before the 18-core Xeons reach their 3.7 GHz turbo ceiling

How much heat and noise should I expect when it runs all day in a chassis?

As a half-height blade it relies on the M1000e or MX chassis fans; the dual 18-core CPUs and 128 GB DDR4 will push chassis cooling to its higher speed curves
