Dell PowerEdge R640 40-core rack server

This Dell PowerEdge R640 is a 1U rackmount server system built for business workloads such as virtualization, databases, file storage and application hosting. It ships new with two Intel Xeon Gold 6148 processors, 128GB of DDR4 memory and eight 1TB SATA SSDs. The H730P storage controller simplifies array setup and ongoing management.

Dual Xeon Gold 6148 24-core CPUs

The decisive specification is the dual-processor configuration: two Gold 6148 CPUs deliver 40 total cores at 2.40GHz in LGA3647 sockets. This core count and clock speed determine whether the server can handle your planned virtual machine density or database concurrency. The platform supports up to 3TB of DDR4 when the workload grows.

Sustained load with H730P and X710

Under continuous demand the H730P controller manages the eight 2.5-inch SSDs for steady throughput, while the X710 network adapter maintains consistent connectivity. Integrated graphics and front-panel LEDs for power, Ethernet and USB give basic status without extra hardware. The 60kg chassis is designed for rack airflow during extended operation.

Questions about this item

What does the 40-core total mean for virtualization workloads?

Two 24-core Xeon Gold 6148 processors give 48 physical cores to schedule virtual machines and containers with minimal contention.

What does the X710 network interface cap in practice?

The X710 provides dual 10 GbE ports so throughput tops out at 10 gigabits per second per port.

What rail kit does the 1U R640 need to mount in a rack?

It requires Dell ReadyRails sliding rails for a 1U server; the chassis has the standard mounting holes for that kit.
