DELL PowerEdge M640 Blade 2x Xeon Platinum 8253 2.2 GHz 384GB DDR4 2x 4TB SATA

Dual-socket blade for dense compute

The Dell PowerEdge M640 blade fits a 2U chassis and delivers two Xeon Platinum 8253 processors running at 2.2 GHz with 16 cores each. With 384 GB of DDR4 ECC registered memory installed and a maximum capacity of 1 TB, it targets virtualization clusters and database workloads that need high core counts in a compact form factor.

Sustained load behaviour

Both CPUs share a PERC H330 SAS storage controller driving two 4 TB SATA 2.5-inch drives, while a 10 GbE 2-port 562T adapter handles network traffic. The integrated graphics and iDRAC9 Enterprise remote management operate independently of the main processors, so firmware updates and monitoring continue during heavy compute runs without stealing cycles from the Xeons.

Interface practical limits

The SATA interface on the installed drives caps sequential throughput well below the SAS backplane potential, and the two-drive bay limit restricts total raw capacity to 8 TB in this configuration. Memory expansion stops at 1 TB across the DDR4 slots, and the blade supports a maximum of two processors, so growth beyond the current dual 8253 setup requires a different platform.
