Dell PowerEdge R640 40-core rack server
The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases and application hosting. Two Intel Xeon Gold 6148 processors deliver 40 total cores at 2.40GHz, paired with 128GB of DDR4 memory and eight 1TB SATA SSDs. An integrated GPU and the H730P storage controller complete the configuration for immediate deployment.
Suited for consolidation and storage-heavy tasks
This server fits environments that need high core density and local flash capacity in a single rack unit. The eight 2.5-inch drive bays are fully populated, leaving no room for additional internal drives. Buyers who require more storage bays, discrete graphics acceleration or a different processor generation should evaluate alternative platforms.
Dual Xeon Gold 6148 40-core processor configuration
The installed CPUs provide 20 cores each for a combined 40 cores, setting the ceiling for simultaneous threads and virtual-machine density. This core count is the primary factor when sizing the server for hypervisor licensing, database concurrency or compute-intensive workloads.

Questions about this item
Does the R640 ship with rails, cables or an operating system, or do I need to buy them separately?
The server arrives with the two Xeon Gold 6148 CPUs, 128GB DDR4, the H730P controller, the X550-T4 quad-port adapter and eight new 1TB SATA SSDs already installed. Rails, power cords and an OS licence are not included.
Should I choose the 8-bay 2.5" version or a different chassis for this R640?
This unit is the 8-bay 2.5" SFF chassis (8B SFF). It holds up to eight 2.5" drives, which are already populated with the 1TB SSDs. A 12-bay or 3.5" chassis would be a different part number.
What does the 40-core figure mean for actual VM density on this box?
Two Gold 6148 chips give 40 physical cores at 2.40GHz. With 128GB DDR4 and the H730P controller, typical virtualisation workloads run 30–50 VMs before CPU scheduling becomes the bottleneck.
