Blade compute density

The Dell PowerEdge M640 is a half-height blade server built for dense virtualization, private cloud and high-performance computing clusters. Two Xeon Gold 6230 processors provide 20 cores each at 2.1 GHz with 3.9 GHz turbo, delivering 40 threads in a single blade slot. It targets operators who need maximum compute per chassis bay without exceeding the M1000e or MX enclosure limits.

Dual-socket 20-core ceiling

The blade ships with the maximum of two processors already installed, so no further CPU upgrade is possible. Each socket uses LGA 3647 and the pair reaches 40 total cores, matching the 56-core platform ceiling for this generation. Memory capacity starts at 16 GB DDR4 across 16 slots and can scale to 1.5 TB when fully populated with supported modules.

Sustained throughput under load

The PERC H330 controller manages two 960 GB SATA SSDs in RAID 0, 1, 5, 10 or 50, feeding steady read streams to both 10 Gb ports on the 57810S-K daughter card. iDRAC9 Enterprise provides continuous telemetry and remote power control so the blade remains manageable during extended heavy workloads. GPU output is limited to the Matrox G200 with 8 MB video memory, so graphical acceleration is not available.

Questions about this item

What does the 2.1 GHz base clock on the two Xeon Gold 6230 CPUs mean for real-world throughput?

Two Xeon Gold 6230 processors give 40 physical cores running at 2.1 GHz base frequency, with turbo up to 3.9 GHz for burst workloads.

How does the 12 Gb/s PERC H330 controller limit drive performance with the installed 960 GB SATA SSDs?

The H330 supports 12 Gb/s SAS and 6 Gb/s SATA; the 960 GB SATA SSDs run at 6 Gb/s, so the controller does not bottleneck them.

What chassis and physical space are required to mount this half-height blade?

It fits a half-height slot in a PowerEdge MX or M1000e chassis and uses 2.5-inch drive bays.
