2U Rack Server with 12-Bay Storage

The Dell PowerEdge R750 is a 2U rack server equipped with twelve 3.5-inch drive bays. Dual Intel Xeon Silver 4316 processors provide 20 cores each at 2.3 GHz base and 3.4 GHz turbo. 768 GB of DDR4 2666 MHz registered ECC memory is installed across 24 modules. The PERC HBA355i controller connects twelve 8 TB 7.2K SATA drives in pass-through mode. Dual 10 GbE SFP+ networking and iDRAC9 Enterprise remote management are included.

Verify Rack Space and Power Infrastructure

Confirm the rack can accommodate a 2U chassis with the included ready rails. Ensure the facility provides redundant power circuits for the two 1400 W platinum power supplies. The HBA355i operates in pass-through mode only, so any RAID functionality must be handled by the operating system or a separate controller. Check that SFP+ transceivers and cabling match the Broadcom 57412 OCP 3.0 network adapter. CPU sockets are LGA 4189 if future processor changes are planned.

Sustained Load Behaviour with Dual 1400 W PSUs

Redundant hot-swap power supplies maintain operation during a single unit failure under continuous load. The HBA355i passes I/O directly to the twelve SATA drives without RAID overhead, delivering predictable throughput for sequential workloads. DDR4 2666 MHz memory runs at rated speed across all 24 DIMM slots during extended compute tasks. iDRAC9 Enterprise provides persistent telemetry for thermal and power trends over long periods. The 2U form factor relies on front-to-rear airflow to keep dual 20-core CPUs and dense storage within limits.

Questions about this item

What drives, rails and bezel are included, and what must I add for RAID?

The server ships with twelve 8 TB 7.2K SATA 3.5″ drives, sliding rails and a front bezel. The HBA355i controller provides SAS pass-through only; a PERC RAID card must be purchased separately for hardware RAID.

Should I choose the 768 GB DDR4 configuration or plan for the 2 TB maximum?

This unit already contains twenty-four 32 GB DDR4 2666 MHz registered ECC modules filling all slots for 768 GB. To reach the 2 TB limit you would need to replace every module with higher-capacity DDR4 DIMMs.

What does the 2.3 GHz base and 3.4 GHz turbo mean for my workloads?

Each of the two Xeon Silver 4316 processors runs at 2.3 GHz base with a 3.4 GHz turbo across twenty cores, giving forty cores total for multi-threaded applications such as databases and virtualization.
