High-density blade server

The Dell EMC PowerEdge M640 is a half-height blade server built for virtualization, private cloud and high-performance computing workloads. It installs into PowerEdge MX or M1000e chassis and delivers up to 56 cores per server with Intel Xeon Scalable processors.

Dual Xeon Platinum 8260 thermals

Two Intel Xeon Platinum 8260 24-core processors run at a 2.4 GHz base frequency and can reach 3.9 GHz turbo. The blade form factor relies on the chassis cooling infrastructure to manage heat and acoustic output under normal operation.

Sustained load behaviour

The system supports 128 GB of DDR4 2933 MHz registered ECC memory across 16 slots, expandable to 1.5 TB. Storage uses a PERC S140 controller with two 1.92 TB SATA SSDs in RAID 0, 1, 5 or 10. A Broadcom 57810S-K dual-port 10 Gb network daughter card provides connectivity, while iDRAC9 Enterprise enables remote management.

Questions about this item

How is the blade installed into a PowerEdge MX or M1000e chassis, and which step is most often missed?

Slide the half-height blade into an empty bay until the latch clicks, then use the iDRAC9 Enterprise interface to complete the inventory and firmware baseline before powering on.

What maintenance or replacement will the 2 x 1.92TB SATA SSDs need later?

Monitor SSD wear via the PERC S140 controller; replace a drive when SMART indicates end-of-life, then rebuild the RAID 0/1/5/10 array automatically.

Which limit appears first under sustained load — CPU turbo, memory capacity, or 10 Gb network throughput?

The dual Xeon Platinum 8260 processors hit their 3.9 GHz turbo ceiling before the 128 GB DDR4 2933 MHz memory or the 57810S-K 10 Gb dual-port NIC saturates.
