Dell PowerEdge R640 4LFF server

The Dell PowerEdge R640 is a 1U rack server equipped with a single Intel Xeon Gold 6140 processor running at 2.3GHz and 18 cores. It ships with 256GB of DDR4 ECC registered memory installed across sixteen 16GB modules. The chassis supports four 3.5-inch drive bays and includes a PERC H740P RAID controller. Remote management is handled by iDRAC9 with an Enterprise licence.

Suited for virtualisation hosts needing dense memory

This configuration fits environments that prioritise high core count and large memory capacity in a 1U form factor, such as virtualisation clusters or database nodes. The single processor leaves one socket open for future expansion up to two CPUs. Buyers who need installed storage drives, a second processor from the start, or GPU acceleration should look at other configurations.

256GB DDR4 ECC registered memory installed

The system arrives with 256GB of DDR4 ECC registered RAM populated in sixteen 16GB DIMMs, reaching a substantial portion of the 7.68TB maximum capacity. This memory size determines how many virtual machines or in-memory workloads the server can handle immediately. Verify that your workload fits within this capacity or plan for additional modules.

Preguntas sobre este artículo

What rack depth does the 36 x 24 x 10 in chassis need?

The server is 36 inches deep, so the rack must provide at least that much clear depth plus cable clearance at the rear.

How is the PERC H740P controller installed, and what step is often missed?

The controller fits in the dedicated internal slot; the step often missed is attaching the RAID battery module and seating it firmly before closing the chassis.

When will the 256 GB DDR4 memory need replacement or expansion?

The system holds 256 GB in sixteen 16 GB modules and supports up to 7.68 TB, so expansion is only needed when workloads exceed the current capacity.
