PowerEdge R750 2U server

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads that demand high core counts and large memory capacity. It ships with two Intel Xeon Silver 4314 processors, each running at 2.4 GHz with 16 cores and a 3.4 GHz turbo frequency. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules, leaving 24 slots available for expansion. Twenty-four 2.5-inch SATA solid-state drives of 1.92 TB each provide substantial flash storage managed by a PERC H755 RAID controller.

Sustained load behaviour

Dual 1400-watt platinum power supplies and redundant hot-swap cooling keep the platform stable during extended compute tasks such as database processing or virtualisation clusters. The H755 controller includes 8 GB of non-volatile cache with battery backup, protecting write performance during prolonged I/O bursts. Quad-port 1 GbE networking via the Broadcom 5720 OCP 3.0 adapter maintains consistent throughput for distributed workloads. iDRAC 9 Enterprise enables continuous remote monitoring and firmware updates without host downtime.

Installation and common issues

The server arrives with ready rails and a front bezel, simplifying rack mounting in standard 2U spaces. Cable routing to the 24 front drive bays and the PCIe H755 card requires planning to avoid airflow restriction. Memory population rules for dual-processor Xeon Scalable platforms must be followed to enable all 32 slots; incorrect DIMM placement is the most frequent cause of POST failures. The OCP 3.0 network card occupies a dedicated mezzanine slot, so no standard PCIe lane is consumed.
