Dense compute blade for virtualization and HPC

The Dell PowerEdge M640 is a half-height blade server built for dense compute clusters. Two Xeon Platinum 8260 processors deliver 24 cores each at 2.4 GHz with a 3.9 GHz turbo frequency. 512 GB of DDR4 registered ECC memory fills 16 slots. Dual 960 GB SATA SSDs sit behind a PERC S140 controller supporting RAID 0, 1, 5 and 10.

Suited for scale-out workloads needing integrated

This blade fits organisations running virtualization, private cloud or high-performance computing that can use the installed Broadcom 57810S-K dual-port 10 Gb daughter card. Buyers who need Fibre Channel connectivity or GPU acceleration should look elsewhere because the server only provides a Matrox G200 with 8 MB video memory and no PCIe expansion is mentioned.

Two-socket LGA 3647 limit defines maximum

The chassis accepts a maximum of two processors in LGA 3647 sockets, so the installed pair of Xeon Platinum 8260 CPUs already reaches the hard ceiling. Any future upgrade would require replacing both processors rather than adding a third.

Questions about this item

How do I confirm the blade is operational after installing it in the chassis?

The iDRAC9 Enterprise remote-management interface provides system health, power status and hardware inventory over the network once the blade is seated and powered.

Which components are included and which must be sourced separately?

The unit ships with two Xeon Platinum 8260 processors, 512GB DDR4 in 16 slots, two 960GB SATA SSDs, the PERC S140 controller and the 57810S-K 10Gb dual-port daughter card; front bezel, ready rails and an operating system are not included.

Should I choose the 512GB configuration or the 1.5TB maximum capacity for virtualization?

The installed 512GB uses 16×32GB DDR4 2933MHz modules filling every slot; reaching 1.5TB would require replacing all modules with higher-capacity DDR4 DIMMs.
