Dual Xeon Gold 6128 blade server

The Dell PowerEdge M640 is a two-socket blade server fitted with Intel Xeon Gold 6128 processors running at 3.4 GHz and 192 GB of DDR4 ECC registered memory. It targets virtualisation hosts, database nodes and compute clusters that need dense processing in a shared chassis. Buyers who need GPU acceleration or more than two internal drives should look elsewhere.

Thermals and power in a shared chassis

The blade relies on the enclosure's cooling fans and redundant power supplies, so its own thermal output and acoustic profile are determined by the chassis configuration rather than an independent fan array. Power draw scales with the dual 6-core CPUs and the PERC H330 controller driving two 4 TB SATA drives. No standalone noise or wattage figures are provided for the blade alone.

iDRAC9 Enterprise and 10 GbE networking

Remote management comes from iDRAC9 Enterprise, enabling out-of-band monitoring, firmware updates and virtual console access without an operating system. A dual-port 10 GbE 562T adapter provides high-speed fabric connectivity for storage replication or VM migration. Rail kits are available on request for rack mounting the enclosure.

Questions about this item

How do I insert the M640 blade into a Dell PowerEdge chassis and which step is commonly missed?

Slide the blade into the chassis slot until the latch clicks, then verify iDRAC9 Enterprise shows the blade online before applying power to the CPUs.

What components in this M640 blade will need replacement over time?

The two 4 TB SATA 2.5" drives and the PERC H330 controller are the primary field-replaceable units; DDR4 ECC registered DIMMs can be swapped if a memory error is logged.

What limit appears first when the dual Xeon Gold 6128 CPUs run at 3.4 GHz under sustained load?

Thermal throttling in the blade enclosure typically triggers before the 192 GB DDR4 memory bandwidth or the 10 GbE 562T adapter saturate.
