Virtualization Rack Server

The Dell PowerEdge R640 8B is a 1U rackmount server system built for business workloads such as virtualization, databases, backups, and application hosting. It operates with two Intel Xeon Gold 6150 processors running at 2.70GHz, delivering a combined 36 cores and 72 threads for multi-threaded performance. The system includes 256GB of DDR4 ECC Registered memory and an integrated GPU for display output. A PERC H740P RAID controller manages the storage subsystem, while dual 10GbE X540 and dual 1GbE I350 network adapters provide connectivity.

Suits virtualization and compute-heavy deployments

This configuration suits IT teams deploying large-scale virtualization, container hosting, ERP, analytics, or storage-heavy business applications. The 8x 1.2TB 10K RPM SAS drives in hot-swap 2.5-inch bays offer high-speed, reliable storage capacity for operating systems, virtual machines, and business data. Buyers who need GPU-accelerated workloads, larger memory footprints beyond 3TB, or different drive interfaces should evaluate alternative platforms. The server ships without an operating system, requiring separate provisioning.

8-bay 2.5-inch SAS storage limit

The single specification that decides fit is the 8-bay 2.5-inch chassis populated with 1.2TB 10K SAS drives and the H740P controller. This defines the maximum internal drive count, the drive form factor, and the storage protocol available without external enclosures. If the deployment requires more than eight drives, 3.5-inch form factors, or a different storage protocol, this chassis does not meet the requirement.

Questions about this item

Does the Dell PowerEdge R640 need an operating system installed before I can use the 36 cores and 256GB DDR4 memory?

Yes, the server ships without an operating system so you must install your preferred hypervisor or OS to access the 36 cores and 256GB DDR4 memory.

Will the dual 10GbE X540 ports work with my existing 1GbE switches?

The X540 ports auto-negotiate down to 1GbE, so they connect directly to current 1GbE switches without extra hardware.

How can I confirm the PERC H740P controller sees all eight 1.2TB SAS drives after first boot?

Open the controller BIOS during POST and verify all eight drives appear in the physical disk list with 1.2TB capacity each.
