Blade server for virtualisation and HPC

The Dell PowerEdge M640 is a half-height blade built for dense compute in the PowerEdge MX and M1000e chassis. It targets IT teams running virtualisation, private cloud or high-performance computing workloads that need many cores in a small footprint. This unit ships without an operating system, front bezel or ready rails.

Dual 18-core Xeon Gold 6154 at 3.0 GHz base

Two Intel Xeon Gold 6154 processors provide 36 total cores with a 3.7 GHz turbo frequency. The board uses LGA 3647 sockets and supports a maximum of two CPUs. Memory consists of 512 GB DDR4 2666 MHz registered ECC across 16 slots, expandable to 2 TB. Storage is handled by a PERC H330 controller with RAID 0/1/5/10/50 and two 960 GB SATA SSDs installed.

Network daughter card and remote management

A Broadcom 57810S-K dual-port 10 Gb blade network daughter card handles data traffic. iDRAC 9 Enterprise provides out-of-band monitoring and automation. The integrated Matrox G200 graphics controller with 8 MB video memory serves basic console output. Power draw and thermal output follow the chassis specification for half-height blades.

Questions about this item

What real-world throughput does the 3.7 GHz turbo frequency deliver once the blade is installed in a chassis?

The two 18-core Xeon Gold 6154 CPUs run at 3.0 GHz base and can reach 3.7 GHz turbo, giving up to 56 cores of compute capacity for virtualization or HPC workloads.

How does the PERC H330 controller’s 12 Gb/s SAS/SATA interface limit drive performance in practice?

The controller supports RAID 0, 1, 5, 10 and 50 across the two 960 GB SATA SSDs and any additional SATA or SAS drives you add to the two 2.5-inch bays.

What chassis slots and mounting hardware are required to install this half-height blade?

The M640 fits a half-height slot in a PowerEdge MX or M1000e chassis; front bezel and ready rails are not included with the blade.
