Server Configuration

The Dell PowerEdge R640 is a 1U rackmount server equipped with two Intel Xeon Gold 6126 processors running at 2.6GHz and 384GB of DDR4 ECC registered memory. It targets organisations that need dense compute and large memory capacity for virtualisation, database or high-performance workloads in a compact form factor.

Drive Bay Flexibility

The chassis provides four 3.5-inch large-form-factor bays with a Dell PERC H740P RAID controller supporting SATA drives. No drives are installed, so buyers must supply their own storage to match capacity and performance requirements.

Memory Headroom

The system ships with 384GB of DDR4 across its DIMM slots and supports a maximum of 7.68TB when fully populated. This headroom suits heavy in-memory applications, though reaching the ceiling requires additional memory modules not included in this configuration.

Questions about this item

What does the 2.6 GHz clock speed mean for actual workloads with two Xeon Gold 6126 processors?

Each Gold 6126 has 12 cores at 2.6 GHz base frequency, giving 24 total cores for parallel tasks such as virtualisation or database work.

What does the PERC H740P controller cap for SATA drive performance?

The PERC H740P manages RAID across the SATA interface; throughput is limited by the SATA link speed of each installed drive.

Will the 4LFF chassis fit in a standard 19-inch rack and what clearance does it need?

The unit measures 36 x 24 x 10 inches and weighs 40 units; it occupies 1U in a standard 19-inch rack with front-to-rear airflow clearance.
