Dual-processor blade server for dense compute

The Dell PowerEdge M640 fits into a blade enclosure and delivers two Xeon Silver 4215 processors running at 2.5 GHz with eight cores each. It targets organisations that need high core counts in a shared chassis for virtualisation, database or high-performance computing workloads.

256 GB DDR4 with room to 1 TB and 1.8 TB SAS storage

Installed memory is 256 GB of DDR4 ECC registered DIMMs across the available slots, leaving headroom to reach the 1 TB maximum. Two 900 GB 10K SAS drives provide 1.8 TB of fast mechanical storage managed by the PERC H330 RAID controller.

iDRAC9 Enterprise and 10 GbE for remote operations

Integrated iDRAC9 Enterprise gives full out-of-band control including virtual console and power management. A dual-port 10 GbE 562T adapter supplies high-throughput networking, while the blade form factor relies on the enclosure for power, cooling and additional I/O expansion.

Questions about this item

How do the two Xeon Silver 4215 CPUs at 2.5 GHz share the DDR4 memory channels with existing blades in the same chassis?

Each processor provides its own memory controllers for the installed 256 GB DDR4 ECC registered DIMMs; the blade operates independently within the shared chassis infrastructure.

What indicators confirm the PERC H330 controller and iDRAC9 Enterprise are operational after the blade is seated?

The iDRAC9 web interface becomes reachable at its assigned address and the PERC H330 BIOS utility reports both 900 GB SAS drives in a healthy RAID configuration.

Which components ship installed and which must be sourced separately for this M640 blade?

The blade arrives with two Xeon Silver 4215 processors, 256 GB DDR4 ECC registered memory, two 900 GB 10K SAS drives, PERC H330 RAID controller and a 10 GbE 2-port 562T adapter; rail kits are available on request.
