Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Silver 4110 processors, 512GB of DDR4 ECC memory and eight 2.4TB SAS hard drives. Redundant 750W power supplies and iDRAC9 Enterprise remote management are included.

Suited for virtualisation and database workloads

This configuration fits environments that need high core counts, large memory capacity and SAS storage in a single rack unit. Buyers who require GPU acceleration or solid-state storage should evaluate other platforms. The system maxes out at two processors and 3TB of memory.

512GB DDR4 installed memory

The server arrives with 512GB across 24 DIMM slots, leaving room to grow toward the 3TB maximum. Memory type and speed are fixed to DDR4 2400MHz registered ECC modules. Confirm your application can use registered ECC before purchasing.

Questions about this item

What drive maintenance will the eight 2.4 TB SAS hard drives eventually need?

The eight 2.4 TB 10K SAS drives are mechanical units; plan to replace any that develop read errors or exceed their rated workload limits.

Which component reaches its limit first when the two Xeon Silver 4110 processors run at full load continuously?

The 750 W redundant power supplies set the sustained power ceiling for the dual 8-core CPUs and 512 GB DDR4 memory.

How much fan noise and heat should I expect from the 1U chassis with dual 750 W power supplies running all day?

The 1U rack design uses high-speed fans to cool two Xeon CPUs, 512 GB DDR4 and eight SAS drives, producing noticeable airflow and heat output.
