Dense two-socket blade for virtualised workloads

The Dell PowerEdge M640 blade fits a 2.5-inch form factor and carries two Xeon Silver 4210 processors running at 2.2 GHz, each with ten cores and 13.75 MB cache. Installed memory totals 192 GB of DDR4 ECC registered RAM, while storage is handled by two 1.8 TB SAS hard drives behind a PERC H330 RAID controller. Remote management is provided by iDRAC9 Enterprise and a dual-port 10 GbE 562T adapter handles network traffic.

Suited for consolidation projects needing maximum

Teams building dense virtualisation clusters or running memory-heavy databases will benefit from the dual-socket layout and 1 TB maximum memory ceiling. The blade only accepts two 2.5-inch drives, so workloads that demand large local storage arrays or high IOPS from flash media should evaluate other platforms.

Dual-socket limit defines scaling ceiling

The chassis supports exactly two processors and cannot be upgraded beyond that count, making the installed pair of Xeon Silver 4210 CPUs the final compute capacity for this blade.

Questions about this item

Should I pick the dual 10-core Xeon Silver 4210 at 2.2 GHz or look for a different CPU count?

The chassis holds a maximum of two processors and this unit already has both sockets filled with 10-core 2.2 GHz Xeon Silver 4210 chips, so there is no room to add more CPUs later.

How does the 192 GB DDR4 ECC registered memory perform inside the M640 blade?

The 192 GB installed uses DDR4 ECC registered modules; the system supports up to 1 TB total, leaving headroom for future expansion if workloads grow.

What does the PERC H330 SAS RAID controller limit in practice?

The PERC H330 manages the two 1.8 TB SAS drives and caps performance to the SAS interface and RAID overhead, defining the storage throughput ceiling.
