Dual-socket Xeon server for virtualisation workloads

The PowerEdge R750 fits a standard 2U rack slot and ships with two Intel Xeon Silver 4314 processors running at 2.4 GHz with a 3.4 GHz turbo frequency. Sixteen cores per socket provide 32 threads for dense virtualisation, database or analytics tasks. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots, with headroom to reach 2 TB total capacity.

Twelve front 3.5-inch trays and pass-through HBA

Twelve hot-swap trays accept 3.5-inch SAS or SATA drives and connect to a PERC HBA355i host bus adapter that presents disks directly to the operating system without hardware RAID abstraction. A Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 mezzanine card handles high-speed network traffic. iDRAC 9 Enterprise provides dedicated out-of-band remote management. ReadyRails sliding rails and a front bezel are included for immediate rack integration.

Redundant 1400 W platinum supplies and 2U airflow

Dual 1400 W platinum-efficiency power supplies operate in redundant hot-swap mode, maintaining uptime if one unit fails. The 2U chassis directs front-to-rear airflow across both CPU sockets, memory banks and drive trays, keeping thermals stable under sustained load. Fan speeds adjust automatically through iDRAC policies, balancing acoustic output against inlet temperature in typical data-centre aisles.

Questions about this item

What PCIe generation does the HBA355i controller use, and what throughput ceiling does that impose on the 12 drive bays?

The PERC HBA355i is a PCIe Gen4 x8 adapter, so the 12 SAS/SATA bays share a 16 GT/s link, capping aggregate throughput at roughly 16 GB/s before protocol overhead.

What mounting hardware is included for rack installation?

The server ships with Dell ReadyRails sliding rails and a front bezel, enabling tool-less mounting in standard four-post racks with square or round holes.

How is the HBA355i configured for the 12 drive bays, and what common step is missed during setup?

The HBA355i operates in pass-through mode only; each of the 12 bays appears as a raw device, and users often forget to create virtual disks in the OS or a separate RAID controller because the HBA presents no logical volumes.
