Enterprise 2U rack server

The Dell PowerEdge R750 is a 2U rack server built for data-intensive enterprise workloads. It ships with dual Intel Xeon Silver 4316 processors running at 2.3GHz with 20 cores each and 256GB of DDR4 2666MHz registered ECC memory across eight DIMM slots.

Virtualisation hosts and database clusters

This configuration suits organisations running virtualisation platforms, large databases, or analytics workloads that benefit from high core counts and large memory capacity. Buyers who need hardware RAID protection or NVMe performance should evaluate other controller and drive options.

HBA355i pass-through controller

The storage subsystem uses a Dell PERC HBA355i SAS 12Gb/s host bus adapter that provides pass-through connectivity only, with no RAID functionality. Twelve 4TB 7.2K SATA 3.5-inch drives are installed, delivering raw capacity without redundancy unless configured in software.

Questions about this item

What drive maintenance will the twelve 3.5" 7.2K SATA bays need over time?

Each 4 TB SATA drive is a mechanical unit; plan to replace any disk that SMART flags or that exceeds its rated workload, using the hot-swap bays without powering down the R750.

Which resource hits its ceiling first during continuous heavy compute on the dual Xeon Silver 4316 20-core CPUs?

The two 2.3 GHz 20-core processors share a 2 TB DDR4 memory ceiling; sustained all-core turbo at 3.4 GHz will saturate memory bandwidth before the 1400 W platinum PSUs reach their thermal limit.

How much heat and fan noise do the twin 1400 W platinum supplies and HBA355i controller produce in a 2U rack running all day?

Dual 1400 W platinum PSUs and the PERC HBA355i pass-through adapter draw steady power; the 2U chassis fans ramp to keep CPU and drive temperatures in spec, producing typical rack-level acoustic output.
