Blade server for virtualization and HPC

The Dell PowerEdge M640 is a half-height blade server built for dense compute workloads such as virtualization, private cloud and high-performance computing. It ships with two Intel Xeon Gold 6154 processors running at 3.0 GHz with 3.7 GHz turbo across 18 cores each. Installed memory is 64 GB of DDR4 2666 MHz registered ECC across four modules. Storage uses a PERC S140 controller with two 960 GB SATA SSDs in a 2.5-inch bay.

Suits dense racks; not for standalone towers

This blade fits Dell PowerEdge MX and M1000e chassis, so it suits operators who already run those enclosures and need up to 56 cores per node with room to grow to 1.5 TB of memory. Buyers who need a tower or rack-mount server that operates outside a blade chassis should look elsewhere. The integrated Matrox G200 graphics with 8 MB video memory is for management only and cannot drive graphical workloads. No operating system is included.

Slides into chassis; check enclosure compatibility

Installation means sliding the blade into a compatible MX or M1000e slot and cabling the 10 Gb dual-port Broadcom 57810S-K daughter card. iDRAC9 Enterprise gives full remote control once the chassis management module is configured. Common issues are mismatched chassis firmware, missing mezzanine cards for extra I/O, and forgetting that front bezel and ready rails are not supplied. Memory population rules for 16 slots must be followed to reach maximum capacity.

Questions about this item

Which chassis models accept this half-height blade server?

It fits Dell PowerEdge MX and M1000e chassis, which supply power, cooling and the backplane connections the blade needs.

Can the installed PERC S140 controller also manage SAS hard drives that I might keep from an older array?

Yes, the S140 supports both SATA and SAS interfaces, so legacy SAS drives can be used alongside the supplied 960 GB SATA SSDs.

How do I confirm the iDRAC9 Enterprise remote management is active after the blade is seated?

Open a browser to the iDRAC IP address; the dashboard will show the two Xeon Gold 6154 CPUs, 64 GB DDR4 memory and both 960 GB SSDs.
