Dual-socket Xeon rack server

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Gold 6330 processors, each running at 2.0 GHz with 28 cores. It ships with 1 TB of DDR4 registered ECC memory across 32 DIMM slots and a PERC HBA355i host bus adapter for direct drive access. This configuration targets organisations running virtualisation clusters, large databases or analytics workloads that demand high core counts and memory capacity in a standard rack footprint.

Redundant 1400 W power supplies

Dual hot-swap 1400 W platinum-rated power supplies provide full redundancy for continuous operation under heavy load. Twelve 3.5-inch 8 TB enterprise SATA drives spinning at 7.2 K RPM populate every front bay, so airflow is tuned for sustained sequential throughput rather than burst performance. The Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 adapter handles east-west traffic without saturating the PCIe Gen4 lanes shared with the HBA355i controller.

HBA355i pass-through only

The PERC HBA355i operates strictly in pass-through mode and presents no hardware RAID layer, so any redundancy or tiering must be handled by the operating system or a software-defined storage stack. Buyers who need a hardware RAID controller with cache protection should look elsewhere. The 2 TB maximum memory ceiling also means workloads that scale beyond 1 TB per node will require additional servers rather than a simple DIMM upgrade.

Questions about this item

How do I install the 12x 3.5" drives into the HBA355i controller and which step is commonly missed?

Slide each drive into the front 3.5" bays until the latch clicks, then verify every drive appears in the HBA355i BIOS before booting; the step often missed is confirming the controller sees all 12 SATA ports.

What maintenance will the 2x 1400W power supplies need after extended operation?

Both platinum-efficiency units are hot-swap redundant; replace a failed module by pulling its release handle and inserting the new one without powering down the server.

At what point does the DDR4 2933MHz memory subsystem become the bottleneck under sustained load?

With 32x 32GB DIMMs filling every slot at 2933 MT/s, sustained bandwidth-heavy workloads saturate the memory bus before the 28-core Xeon Gold 6330 CPUs reach full utilisation.
