DELL PowerEdge R750 Rack Server 2U 12x 3.5" 2x Xeon Silver 4310 2.1GHz 512GB DDR4 H755 5720 iDRAC9 2x 1400W

PowerEdge R750 2U rack server

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Silver 4310 processors, each offering 12 cores at 2.1 GHz with 3.3 GHz turbo. It ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules and a PERC H755 RAID controller with 8 GB NV cache. Twelve 3.5-inch drive trays support SAS and SATA devices. A quad-port 1 GbE OCP 3.0 card and iDRAC9 Enterprise provide connectivity and remote management. Dual 1400 W platinum power supplies and rails are included.

Verify power, rack space and memory compatibility

Confirm that your facility can supply two 1400 W circuits and that the 2U height fits the allocated rack enclosure. The system uses LGA 4189 sockets and DDR4 registered ECC DIMMs; ensure any additional modules match the 2666 MHz specification and do not exceed the 2 TB maximum capacity. The PERC H755 controller handles SAS and SATA drives; NVMe devices would require a different backplane or adapter not present in this configuration. The OCP 3.0 network card occupies one mezzanine slot.

Sustained load behaviour with dual 1400 W supplies

Under continuous heavy compute workloads the dual Xeon Silver 4310 CPUs maintain performance within the thermal envelope of the 2U chassis, aided by redundant hot-swap power supplies that share load and provide failover. The PERC H755 controller's battery-backed cache preserves write throughput during extended RAID rebuilds or parity calculations. iDRAC9 Enterprise enables ongoing telemetry monitoring and remote power cycling without physical access, supporting uninterrupted operation in dense rack deployments.
