Blade server for dense compute

The Dell PowerEdge M640 blade server fits into a dense chassis and delivers two Xeon Silver 4112 processors running at 2.6 GHz with 32 GB of DDR4 ECC memory. It includes a PERC H330 SAS storage controller managing two 1.8 TB SAS hard drives and an integrated 10 Gb Ethernet adapter for high-speed networking. Remote management is handled by iDRAC9 Enterprise.

Suited for virtualisation hosts and database nodes

This configuration works for organisations that need a compact blade with dual CPUs and integrated 10 Gb connectivity for virtualised workloads or moderate database serving. Buyers who need more than two drive bays or who require GPU acceleration should evaluate other platforms. The installed 32 GB of DDR4 may also limit memory-intensive applications.

Dual Xeon Silver 4112 at 2.6 GHz

The pair of Xeon Silver 4112 processors provides eight cores total with 8.25 MB cache each, setting the baseline compute capacity for this blade. This CPU choice determines the thread count and clock speed available for every workload running on the server.

Questions about this item

What enclosure slot width does the M640 blade require?

The blade measures 22 x 22 x 10 in and weighs 20, so it occupies a standard half-height slot in a compatible Dell blade enclosure.

Which step is often missed when installing the PERC H330 controller?

After seating the blade, you must use iDRAC9 Enterprise to initialise the RAID volume before the operating system sees the two 1.8 TB SAS drives.

When should the 32 GB DDR4 modules be replaced?

Plan replacement when the system reaches the 1 TB memory ceiling or when ECC correctable errors rise above the platform threshold.
