PowerEdge R640 8-bay virtualisation server

The Dell PowerEdge R640 is a 1U rackmount server built for virtualisation, database and application hosting workloads. Two Intel Xeon Gold 6148 processors deliver 40 cores at 2.40 GHz with 256 GB of DDR4 memory installed. Eight 2.5-inch drive bays hold 1.2 TB 10K SAS drives managed by an H730P controller. The system ships without an operating system.

Dual Xeon Gold 6148 40-core processor configuration

The two-socket LGA3647 layout reaches the maximum of two processors, each with 18 cores running at 2.40 GHz. This 40-core total is the specification that determines whether the server can handle the intended virtual machine density and database concurrency. Memory scales to 3 TB across DDR4 slots when workloads grow beyond the factory 256 GB.

Slide-in rails and tool-less drive carriers speed

The chassis uses toolless 2.5-inch carriers so the eight SAS drives can be seated in seconds. H730P configuration is handled through the BIOS or iDRAC before the first boot. The only common issue is forgetting to initialise the virtual disks on the controller, which leaves the array invisible to the installer.

Questions about this item

What does the 40-core total from the two Gold 6148 CPUs mean for virtualization density?

The dual 18-core Xeon Gold 6148 processors deliver 40 logical cores at 2.4 GHz, letting you run more virtual machines per host without oversubscribing CPU resources.

How does the SAS 12 GB/s interface on the H730P controller limit drive throughput?

The H730P connects the eight 1.2 TB SAS drives at 12 Gb/s per lane, so sustained sequential transfers are capped at the controller's 12 Gb/s link speed rather than the drive media rate.

What rack space and drive cage does the 8-bay 2.5-inch front section require?

The server occupies 1U of rack height and uses an 8-bay 2.5-inch front drive cage that slides directly into the chassis without additional brackets.
