Built for virtualization and data workloads

The Dell PowerEdge R640 is a 1U rackmount server configured with dual Intel Xeon Gold 6148 processors running at 2.40GHz. Forty total cores and 128GB of DDR4 memory deliver capacity for virtualization, databases, file storage and application hosting. An integrated H730P controller manages eight 600GB 10K SAS drives in 2.5-inch bays.

Suited to multi-service consolidation.

This platform fits teams consolidating multiple virtual machines, business applications or backup targets onto one chassis. Buyers who need GPU acceleration, high-speed flash storage or single-thread optimisation should evaluate alternative platforms. The two-socket limit and integrated graphics also rule out heavy compute or visualisation tasks.

40 cores across two Xeon Gold 6148 CPUs

The installed processor pair provides 40 cores at 2.40GHz, defining the server's parallel throughput ceiling. Memory scales to 3TB of DDR4 across 24 DIMM slots, while the eight-bay chassis holds 600GB SAS disks. Confirm core count and memory headroom match your licensing and workload sizing before deployment.

Questions about this item

Will the 2.4GHz Xeon Gold 6148 CPUs and H730P controller work with my existing DDR4 memory modules?

The system ships with 128GB of DDR4 installed and supports up to 3TB total, so your existing DDR4 modules can be added if they match the server's registered ECC requirements and speed rating.

How can I verify the 40-core dual Xeon configuration and 8x 600GB SAS array are operating correctly after installation?

Check the front-panel LEDs for power and drive activity, then use the iDRAC interface or BIOS to confirm both 24-core processors report 2.40GHz, all 128GB DDR4 is detected, and the H730P shows the 8-bay SAS array as optimal.

Which items are included in the box and what must I purchase separately for the R640 8-bay SFF server?

The chassis includes two Xeon Gold 6148 CPUs, 128GB DDR4, H730P controller, CX422A adapter, and eight 600GB 10K SAS drives in the 2.5-inch bays; you will need to supply an operating system, rack rails, and power cords.
