DELL PowerEdge R750 2U 12x3.5" 2x Xeon Gold 6338 128GB DDR4 H755 12x4TB 57412 iDRAC9 2x1400W Bezel Rails

Server purpose and audience

The Dell PowerEdge R750 is a 2U rack server built for data-intensive enterprise workloads. It suits organisations that need dense compute and large local storage in a standard rack footprint. The dual-processor design targets virtualisation clusters, database servers and analytics platforms. Buyers who need a compact 1U form factor or a tower chassis should look elsewhere.

Sustained-load behaviour

Two Xeon Gold 6338 processors run at 2.0 GHz base frequency with a 3.2 GHz turbo ceiling across 32 cores each. The 128 GB of DDR4 3200 MHz registered ECC memory feeds all cores without bottlenecks. The H755 controller with 8 GB NV cache absorbs write bursts during continuous database or logging activity. Platinum 1400 W redundant supplies maintain stable voltage under full CPU and drive load.

Interface practical limits

Twelve 3.5-inch bays accept SATA or SAS drives at 6 Gb/s and NVMe devices through PCIe Gen4 lanes. The 57412 dual-port 10 GbE SFP+ OCP 3.0 card connects to top-of-rack switches without proprietary cabling. iDRAC9 Enterprise provides out-of-band management over a dedicated network interface. Memory capacity tops out at 2 TB across 32 DDR4 slots when future expansion is required.
