Dual Xeon Gold 6148 Rack Server

The Dell PowerEdge R640 is a 1U rackmount server system configured with two Intel Xeon Gold 6148 processors running at 2.40GHz. It delivers 40 total cores for businesses running virtualization, databases, file storage, backup workloads and application hosting in a compact form factor.

512GB DDR4 Memory and 8-Bay SAS Storage

The system ships with 512GB of DDR4 RAM installed and supports a maximum capacity of 3TB, providing headroom for memory-intensive virtual machines and data-heavy applications. Eight 2.5-inch drive bays are populated with 1.2TB 10K SAS hard drives operating at 12Gb/s, managed by an H730P storage controller.

LGA3647 Dual-Socket Limit

The platform uses the LGA3647 socket and is factory-limited to a maximum of two processors, so the installed 40-core configuration already reaches the ceiling for CPU expansion. Buyers who anticipate scaling beyond two sockets must evaluate alternative server architectures.

Questions about this item

Will the eight 2.5-inch bays accept the SAS drives I already use in an older PowerEdge?

The eight 2.5-inch bays are populated with eight 1.2TB 10K SAS drives, so existing 2.5-inch SAS drives with the same connector will fit the same backplane.

How can I verify the dual Xeon Gold 6148 processors and 512GB DDR4 are recognised after first boot?

Enter the BIOS or iDRAC interface; both will show two Gold 6148 CPUs at 2.4GHz with 20 cores each and 512GB DDR4 across the memory slots.

Does the box include the H730P controller cable and the X550-T4 quad-port adapter, or must I order them separately?

The H730P storage controller and X550-T4 quad-port 10GbE adapter are already installed; only rack rails and a power cord may need separate purchase.
