DELL PowerEdge R640 8x 2.5" 40-Core 2x Xeon Gold 6148 2.4GHz 128GB DDR4 H730P 8x 600GB SAS rack server

Dual 20-core Xeon for virtualization

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 6148 processors. Each CPU delivers 20 cores at 2.4 GHz, giving 40 cores total for heavy multi-threaded workloads. It ships with 128 GB of DDR4 memory and an H730P RAID controller managing eight 600 GB 10K SAS drives. The platform targets virtualization, database and application hosting roles.

Suits dense compute; not for GPU

This configuration fits teams that need high core density in a single rack unit for virtual machines or container clusters. The integrated graphics and lack of GPU expansion rule out render farms, AI training or VDI workloads that require discrete accelerators. Eight 2.5-inch bays limit raw capacity, so buyers who need dozens of terabytes on local spindles should look at larger chassis.

Fills one 1U slot; needs rack power and networking

The server occupies one rack unit and weighs 55 kg, so the rack must support that load and provide adequate airflow. Dual Xeon LGA3647 sockets and the H730P controller are pre-installed, freeing the builder from CPU cooler mounting and RAID card cabling. Four onboard 10 GbE ports from the X550-T4 handle network connectivity without extra NICs. Memory slots remain open for future expansion up to the platform maximum.
