Built for virtualization and data workloads

The Dell PowerEdge R640 rackmount server ships new with dual Intel Xeon Gold 6148 processors, each running at 2.40GHz across 24 cores for a total of 40 cores. It includes 512GB of DDR4 memory and an H730P storage controller managing eight 1.2TB 10K SAS drives in the 2.5-inch front bays.

Suits teams running databases.

This system targets businesses that need dense compute and local storage in a 1U form factor. Buyers who require GPU acceleration, more than eight drive bays or a larger memory ceiling should evaluate alternative platforms.

40 cores from two Xeon Gold 6148 CPUs

The processor count and core total define the throughput available for virtual machines and multi-threaded services. With both sockets populated the server cannot accept additional CPUs, so the 40-core ceiling is fixed for the life of the unit.

Questions about this item

Should I choose the 8-bay 2.5-inch model or a different bay count for this R640?

This unit ships with eight 2.5-inch bays populated by 1.2TB SAS drives and an H730P controller. Choose this version when you need maximum drive density in a 1U rackmount chassis.

What does the 40-core total mean for actual virtualization performance?

Two Xeon Gold 6148 CPUs each deliver 24 cores at 2.4GHz, giving 48 threads total. The 512GB DDR4 memory supports dense VM consolidation for business workloads.

How does the SAS 12GB/s interface limit real-world drive throughput?

The 1.2TB 10K SAS drives connect at 12GB/s through the H730P controller. Sequential reads approach the drive media limit while random IOPS depend on the 10K spindle speed.
