Blade Server for Virtualisation

The Dell PowerEdge M640 is a half-height blade that fits the PowerEdge MX or M1000e chassis. Two Intel Xeon Platinum 8260 processors run at 2.4 GHz with a 3.9 GHz turbo frequency. Sixty-four gigabytes of DDR4 registered ECC memory occupy four of the sixteen available slots. The server includes a PERC S140 controller and a Broadcom 57810S-K dual-port 10 Gb network daughter card. iDRAC9 Enterprise provides remote management.

Suited for Dense Compute, Not Standalone Use

This blade targets data-centre operators who need maximum CPU density inside a shared chassis for virtualisation, private cloud or HPC workloads. Buyers who require a standalone rack or tower server should look elsewhere, as the M640 has no independent power, cooling or mounting hardware. Organisations needing GPU acceleration will not find PCIe slots for graphics cards in this half-height form factor. Customers who want local NVMe storage must verify that the S140 controller and backplane support their chosen drives.

Dual 10 Gb Network Daughter Card Decides Fit

The installed Broadcom 57810S-K dual-port 10 Gb blade network daughter card is the primary I/O interface. If your chassis fabric or top-of-rack switches cannot terminate 10 Gb Ethernet on the M640's mid-plane connectors, the server cannot communicate. Confirm fabric compatibility before purchase.

Klausimai apie šią prekę

How many DDR4 slots remain open for future memory upgrades?

The blade has 16 DDR4 slots total and ships with 64 GB installed, leaving room to expand toward the 1.5 TB maximum.

Which component hits its ceiling first when the dual Xeon 8260 CPUs run at 3.9 GHz turbo continuously?

The 24-core Platinum 8260 processors reach their 56-core combined limit before the 1.5 TB memory capacity or 10 Gb network becomes saturated.

How much heat and fan noise should I expect from this half-height blade under all-day load?

The M640 relies on the MX or M1000e chassis fans for cooling, so acoustics and thermal output depend on the enclosure configuration rather than the blade alone.
