Purpose-built 2U rack server

The Dell PowerEdge R750 is a 2U rack server fitted with two Intel Xeon Silver 4316 processors. Each CPU provides 20 cores at 2.3 GHz with a 3.4 GHz turbo frequency. The system includes 1 TB of DDR4 2666 MHz registered ECC memory across 32 DIMM slots. It targets organisations running databases, analytics or virtualisation workloads that demand high core counts and large memory capacity in a standard rack footprint.

Thermals noise and power

Two hot-swap 1400 W platinum power supplies deliver redundant power for continuous operation. The 2U chassis uses forced-air cooling designed for dense 2.5-inch drive populations and dual-processor thermal loads. Fan speeds scale with inlet temperature and workload intensity to maintain component limits. Acoustic output rises under sustained compute or storage throughput but remains within typical data-centre norms for this class.

Build integration and expansion

The front bay holds 24 SAS hard drives of 1.8 TB each on a PERC H755 controller with 8 GB NV cache supporting RAID 0, 1, 5, 6, 10, 50, 60. A Broadcom 5720 quad-port 1 GbE OCP 3.0 adapter provides network connectivity. iDRAC 9 Enterprise enables remote management without a local console. Rails and a front bezel are included for rack mounting. PCIe Gen 4 slots remain available for additional accelerators or storage controllers.

Questions about this item

How do I install the 24 x 1.8TB SAS drives into the 2U chassis, and what step is often missed?

Slide each 2.5" drive into the front hot-swap bays until the latch clicks; the step often missed is creating the virtual disks in the H755 controller BIOS before the OS installer runs.

What maintenance will the H755 RAID controller's 8GB NV cache battery need later?

The cache battery is a replaceable module; plan to swap it every 3 to 5 years or when iDRAC 9 Enterprise reports a degraded state to avoid write-cache loss.

What thermal or power limit appears first when both Xeon Silver 4316 CPUs run at 3.4GHz turbo under sustained load?

The 1400W platinum power supplies set the ceiling; if total draw exceeds 1400W the system will throttle before thermal limits are reached.
