Server Configuration

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads. It arrives with two Intel Xeon Gold 6338 processors, each offering 32 cores at 2.0 GHz with a 3.2 GHz turbo frequency. The system includes 768 GB of DDR4 3200 MHz registered ECC memory across 24 DIMM slots. A PERC H755 RAID controller with 8 GB NV cache manages the 12 front-accessible 3.5-inch drive bays.

Target Workloads

This configuration suits organisations running virtualisation clusters, large databases, or analytics platforms that demand high core counts and large memory footprints. The quad-port 1 GbE OCP 3.0 adapter and iDRAC9 Enterprise simplify remote fleet management. Buyers who need 2.5-inch NVMe density, higher single-thread frequencies, or GPU acceleration should evaluate alternative platforms.

Deciding Specification

The 12-bay 3.5-inch chassis with SATA/SAS backplane and H755 controller defines the storage topology. It supports RAID 0, 1, 5, 6, 10, 50, and 60 across twelve large-form-factor drives. Systems requiring native NVMe U.2/U.3 connectivity or 24-bay 2.5-inch density cannot use this chassis.

Questions about this item

How do I install the PERC H755 RAID controller and which step is often missed?

Seat the H755 in its dedicated PCIe slot, connect the SAS cables to the 12-bay backplane, then attach the 8 GB NV cache module and its battery pack before closing the chassis.

What maintenance will the PERC H755 battery-backed cache need later?

The H755 cache battery is a field-replaceable unit; monitor iDRAC9 Enterprise alerts and swap the battery module when the controller logs a capacity-degradation event.

What thermal limit appears first on the Xeon Gold 6338 CPUs under sustained load?

The 32-core Gold 6338 processors hit their package TDP ceiling before the 1400 W platinum supplies reach capacity, triggering clock throttling to stay within thermal design limits.
