Capacity and role

The Dell PowerEdge R750 is a 2U rack server built for data-intensive workloads and virtualization clusters. Dual Intel Xeon Silver 4316 processors provide 20 cores each at 2.3 GHz with 3.4 GHz turbo. A total of 768 GB DDR4 ECC memory is installed across 24 DIMM slots. Twelve 3.5-inch enterprise SATA hard drives deliver 4 TB each for bulk storage.

Sustained load behaviour

Redundant 1400 W platinum power supplies maintain continuous operation under full CPU and storage utilisation. The HBA355i controller passes SAS 12 Gb/s throughput directly to the drives without RAID overhead. Dual 10 GbE SFP+ ports on the OCP 3.0 card sustain high network throughput for distributed workloads. iDRAC 9 Enterprise enables remote monitoring and firmware updates without host downtime.

Build quality and daily implications

The 2U chassis includes ready rails and a front bezel for standard rack integration. Hot-swap drive bays and power supplies allow component replacement while the server remains online. LGA 4189 sockets support a second processor if capacity needs grow beyond the current two. DDR4 2666 MHz registered ECC modules ensure data integrity for mission-critical applications.

Questions about this item

How much heat and power should I expect from the two 1400 Watt PSUs running 24/7?

The server includes two 1400 Watt Platinum efficiency power supplies in redundant hot-swap configuration. Actual draw depends on workload, but the PSUs are rated for high efficiency at typical server loads.

Which host bus adapter or RAID card is required to use the 12 drive bays?

The Dell PERC HBA355i SAS 12Gb/s pass-through HBA is already installed. It provides 12Gb/s SAS connectivity to the 12x 3.5" SATA bays without RAID functions.

Will my existing 2.5" SAS or SATA drives fit the 3.5" bays in this R750?

The 12 front bays are 3.5" form factor. 2.5" drives need appropriate carrier adapters to mount securely in these bays.
