2U Rack Server with 12 Bays

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads. It houses two Intel Xeon Gold 6330 processors running at 2.0GHz with 28 cores each. The system includes 256GB of DDR4 2933MHz registered ECC memory across eight modules. Twelve 3.5-inch drive bays are populated with 8TB 7.2K SATA hard drives connected to a PERC HBA355i host bus adapter.

Suited for High-Capacity Storage Needs

This configuration suits organisations that require dense 3.5-inch storage in a 2U form factor with dual-socket compute performance. The HBA355i provides pass-through SAS connectivity without hardware RAID, so buyers needing integrated RAID levels should look at a different controller option. The 10GbE SFP+ OCP 3.0 network card targets environments with existing SFP+ switching infrastructure.

PERC HBA355i Pass-Through Controller

The storage controller is a Dell PERC HBA355i SAS 12Gb/s PCIe host bus adapter operating in pass-through mode only. It presents the twelve SATA drives directly to the operating system without RAID abstraction. This single specification determines whether the server matches a deployment that requires software-defined storage or a hardware RAID implementation.

Questions about this item

What maintenance will the 12x 8TB 7.2K SATA drives and 2x 1400W PSUs need over time?

The 12 hot-swap 3.5" SATA drives and dual redundant 1400W platinum PSUs are field-replaceable without tools; the iDRAC9 Enterprise console reports predictive failure alerts so you can schedule swaps before a drive or supply degrades.

Which limit appears first when the dual Xeon Gold 6330 28-core CPUs run sustained workloads?

The 256GB DDR4 2933MHz capacity across 8 DIMM slots will saturate before the 2.0GHz base / 3.1GHz turbo processors hit their thermal ceiling, especially with memory-heavy virtualization or analytics jobs.

How much power and heat do the 12 drives, HBA355i and 10GbE OCP card add when the server runs all day?

Twelve 8TB 7.2K SATA drives, the SAS 12Gb/s HBA355i pass-through controller and the Broadcom 57412 dual 10GbE SFP+ OCP 3.0 adapter draw continuous power inside the 2U chassis; the twin 1400W platinum supplies share the load and the iDRAC9 thermal sensors let you track inlet and exhaust temperatures in real time.
