Server Configuration

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Silver 4314 processors. Each CPU runs at 2.4 GHz with 16 cores and a 3.4 GHz turbo frequency. The system includes 1 TB of DDR4 2666 MHz registered ECC memory across 32 DIMM slots. A PERC H755 RAID controller with 8 GB NV cache manages twelve 8 TB 7.2K SATA 3.5-inch drives. Dual 10 GbE SFP+ networking, iDRAC9 Enterprise, redundant 1400 W platinum power supplies, rails and bezel complete the package.

Target Workloads

This server suits organisations that need dense 3.5-inch storage capacity combined with dual-socket compute for virtualisation, databases or analytics. The twelve-bay chassis and H755 controller support RAID 0, 1, 5, 6, 10, 50 and 60 for redundancy or performance. Buyers who require 2.5-inch NVMe density, GPU acceleration or a single-socket platform should evaluate other form factors.

Deciding Specification

The 12-bay 3.5-inch SATA backplane sets the storage ceiling at twelve large-capacity hard drives. If the workload demands more than twelve spindles or needs U.2 NVMe bays, this chassis cannot accommodate them.

Questions about this item

How do you install the 12 x 8 TB 3.5" SATA drives and the H755 controller in the 2U R750, and which step is often missed?

Slide each 3.5" drive into the front hot-swap bays until the carrier clicks, then seat the H755 PCIe card in a Gen4 slot and connect its mini-SAS cables to the backplane; the step often missed is attaching the controller's 8 GB NV cache battery pack before closing the chassis.

What maintenance or replacement will the H755 RAID controller's cache battery and the 7.2K SATA drives need later?

The H755's 8 GB NV cache battery typically requires replacement every 3–5 years to preserve write-back caching, while the 7.2K SATA drives should be monitored via iDRAC9 for SMART errors and replaced pre-emptively when reallocated-sector counts rise.

Which thermal or power limit appears first when both Xeon Silver 4314 processors run sustained turbo loads in this 2U chassis?

The 1400 W platinum power supplies and 2U airflow design will hit their thermal envelope before the CPUs reach their 3.4 GHz turbo ceiling, causing the firmware to throttle core frequencies to stay within the chassis power budget.
