Blade server for dense compute

The Dell EMC PowerEdge M640 is a half-height blade built for virtualisation, private cloud and high-performance computing workloads. Two Intel Xeon Gold 6230 processors provide 40 cores at 2.1 GHz with 3.9 GHz turbo for strong multi-thread throughput. Sixteen gigabytes of DDR4 2666 MHz registered ECC memory and two 1.92 TB SATA SSDs on a PERC H330 controller give a ready-to-deploy platform. iDRAC9 Enterprise enables full remote lifecycle management.

Verify chassis and memory needs

Confirm the blade will sit in a compatible PowerEdge MX or M1000e enclosure with available half-height slots and sufficient power and cooling budget. The system uses LGA 3647 sockets and has 16 DDR4 slots supporting up to 2 TB total, so plan additional registered ECC modules if workloads demand more than the installed 16 GB. The PERC H330 handles RAID 0, 1, 5, 10 and 50 across the two 2.5-inch bays. Network connectivity relies on the Broadcom 57810S-K 10 Gb dual-port daughter card.

Sustained load behaviour

Under continuous demand the twin 20-core CPUs maintain high frequencies within the blade thermal envelope, while DDR4 ECC memory protects data integrity during long-running jobs. The H330 controller delivers consistent I/O to the SATA SSDs across supported RAID levels, and the 10 Gb network ports sustain throughput for clustered workloads. iDRAC9 Enterprise provides telemetry and remote control without host OS dependence, helping operators manage thermal and power headroom over extended periods.

Questions about this item

What comes with the PowerEdge M640 blade and what must I add?

The blade includes two Xeon Gold 6230 processors, 16 GB DDR4 (two 8 GB modules), a PERC H330 controller and two 1.92 TB SATA SSDs. You must add a compatible PowerEdge MX or M1000e chassis, any extra memory up to 2 TB and an operating system.

Should I choose the 1.92 TB SSD pair or add more drives later?

The server has two 2.5-inch bays, both filled with 1.92 TB SATA SSDs. If you need more capacity you must replace these drives; there are no empty bays for expansion.

What does the 2.1 GHz base clock mean once the blade is running?

Each of the 20-core Xeon Gold 6230 CPUs runs at 2.1 GHz base and can turbo to 3.9 GHz, giving 40 cores total for virtualization, cloud or HPC workloads inside a supported chassis.
