DELL PowerEdge R750 2U rack server 2× Xeon Silver 4310 2.1GHz 12-core 256GB DDR4 12× 4TB SAS HBA355i 2× 1400W

PowerEdge R750 dual-Xeon server

The Dell PowerEdge R750 is a 2U rack server fitted with two Intel Xeon Silver 4310 processors running at 2.1 GHz with 12 cores each. It ships with 256 GB of DDR4 ECC memory across eight 32 GB modules and twelve 4 TB SAS hard drives connected to an HBA355i controller. Dual 1400 W platinum power supplies and iDRAC9 Enterprise remote management come standard.

Upgrade from single-socket or older 14G platforms

This configuration replaces single-processor servers or earlier 14th-generation PowerEdge units when workloads need more cores, larger memory capacity, and twelve 3.5-inch drive bays in a 2U form factor. The jump is worth it for virtualisation hosts, database nodes, or analytics clusters that can use twenty-four total cores and up to 2 TB of DDR4. Buyers who need GPU acceleration, all-flash NVMe arrays, or single-thread frequency above 3.3 GHz turbo should look elsewhere.

Tool-less rails and cabled HBA install

The included Ready Rails allow tool-less mounting in standard four-post racks, and the front bezel snaps on without screws. The HBA355i is a PCIe pass-through adapter, so drive cables route directly to the backplane; missing or mis-seated cables are the most common issue. Memory population follows Dell’s optimised sequence — incorrect slot order will halt POST. Network mezzanine card seating should be verified before first power-on.
