Dell PowerEdge R640 36-Core Server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, and application hosting. It runs on two Intel Xeon Gold 6154 processors totalling 36 cores at 3.00GHz. The system includes 256GB of DDR4 memory and eight new 1TB SSDs managed by an H730 controller. Integrated X550 network adapters handle connectivity.

Suits virtualization and database clusters.

This server suits IT teams consolidating virtual machines, hosting business applications, or running storage-heavy databases. The 256GB DDR4 capacity and eight-bay flash array support dense workloads. Buyers needing dedicated GPU acceleration, larger memory footprints beyond 3TB, or desktop form factors should look elsewhere.

Dual Xeon Gold 6154 36-core configuration

The defining specification is the dual-socket layout populated with two Xeon Gold 6154 CPUs delivering 36 total cores at 3.00GHz. This processor choice sets the performance ceiling for virtualization density and database throughput. The LGA3647 platform maxes at two processors, so the installed pair represents the full scaling potential of this chassis.

Questions about this item

Does this R640 need a rackmount cabinet and power cables to operate?

The R640 is a rackmount server; it requires a compatible rack cabinet and appropriate power cords for installation.

Can I keep my existing DDR4 memory modules when adding to the 256GB already installed?

Additional DDR4 modules must match the installed DDR4 type and speed; mixing different DDR generations will not work.

How can I verify the H730 controller sees all eight 1TB SSDs after setup?

Enter the H730 configuration utility during boot to confirm all eight drives appear in the array and show optimal status.
