Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rackmount server system with two Intel Xeon Gold 6148 processors, each delivering 20 cores at 2.4 GHz with a 3.7 GHz turbo frequency. It ships with 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. The platform includes a PERC H730P 2 GB storage controller and eight 300 GB 10K SAS 2.5-inch drives. Dual 750 W platinum power supplies and iDRAC9 Enterprise remote management are also integrated.

Suited for dense scale-out compute

This configuration fits workloads that demand high core counts and large memory capacity in a single rack unit, such as virtualization clusters, database nodes, or high-performance computing tasks. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections for flexible fabric attachment. Buyers who require solid-state storage, GPU acceleration, or 3.5-inch drive bays should consider other platforms because the chassis supports only 2.5-inch SAS/SATA devices and has no PCIe expansion described.

PERC H730P RAID controller with battery

The installed Dell PERC H730P 2 GB controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes, backed by a battery for cache protection. It manages the eight 300 GB 10K SAS drives at 12 Gb/s and can also address SATA media. This single component determines whether the storage topology and data-protection level meet the deployment requirements.

Questions about this item

How loud and hot does the dual 750 W power supply run when both Xeon Gold 6148 CPUs sit at full load 24/7?

The redundant 750 W platinum supplies share the load and spin their fans according to internal temperature sensors, keeping the 1U chassis within Dell's thermal envelope for continuous operation.

Which cables and drive trays must I already have to populate the eight 2.5-inch SAS bays?

The eight 300 GB 10 K SAS drives ship installed in the hot-swap carriers, so no extra trays or cables are needed unless you add more drives later.

Will the PERC H730P controller recognise older 6 Gb/s SAS drives I might reuse?

The H730P supports 12 Gb/s SAS and SATA and will negotiate down to 6 Gb/s for legacy drives, allowing them to join existing RAID sets.
