DELL PowerEdge R750 rack server 2x Xeon Gold 6338 2.0GHz 32-core 64GB DDR4 12x 8TB HDD HBA355i 2U

Dual Xeon Gold 6338 compute platform

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Gold 6338 processors. Each CPU runs at 2.0 GHz with 32 cores, giving 64 cores total for heavily threaded workloads. The system ships with 64 GB of DDR4 3200 MHz registered ECC memory across four DIMM slots. It targets organisations running databases, virtualisation clusters or analytics jobs that demand high core counts and memory reliability.

Sustained throughput with direct-attached storage

Twelve 3.5-inch enterprise SATA hard drives spin at 7.2 K rpm and connect through the Dell PERC HBA355i host bus adapter in pass-through mode. This presents every drive directly to the operating system without a RAID layer, so sustained sequential bandwidth scales with the number of active spindles. Dual 1400 W platinum power supplies and hot-swap redundancy keep the platform online during extended compute runs or drive replacements.

HBA355i pass-through controller decides RAID vs JBOD

The HBA355i operates solely as a SAS 12 Gb/s pass-through device and provides no hardware RAID acceleration. Buyers who need on-board RAID 0, 1, 5, 6 or 10 must select a different PERC model; this server cannot meet that requirement. The controller does support SAS and SATA drives, allowing the installed 8 TB disks or future NVMe U.2 devices to be managed entirely in software.
