Dual Xeon 8260 blade server

The Dell PowerEdge M640 is a half-height blade server built for dense compute environments. Two Intel Xeon Platinum 8260 processors run at 2.4 GHz with a 3.9 GHz turbo frequency, providing 24 cores per socket. Sixteen gigabytes of DDR4 memory and dual 960 GB SATA SSDs complete the base configuration.

Suits virtualization and HPC clusters

This server fits workloads that demand high core counts in a compact blade form factor, such as virtualization farms and high-performance computing clusters. Buyers who need more than 16 GB of memory or who require GPU acceleration should look at other configurations.

Max memory capacity 2 TB

The board supports up to 2 TB of DDR4 across 16 slots, making memory expansion the key specification for scaling this blade. The PERC S140 controller manages the installed SSDs and additional SATA or SAS drives with RAID 0, 1, 5 or 10.

Questions about this item

What PCIe interface does the PERC S140 controller use and what throughput does it cap at?

The PERC S140 is an integrated SATA controller that operates over the chipset PCIe lanes; it supports SATA 6 Gb/s per port, so each attached SSD is limited to that bus speed.

What chassis and slot size does this half-height blade require?

It fits a half-height slot in a Dell PowerEdge MX or M1000e chassis; the blade accepts two 2.5-inch drives and includes a Broadcom 57810S-K dual-port 10 Gb daughter card.

How is the blade installed and what step is often missed?

Slide the blade into the chassis until the latch engages, then use the iDRAC9 Enterprise interface to complete BIOS and RAID configuration before powering on the operating system installer.
