Dual Xeon Silver 4310 server

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Silver 4310 processors. Each CPU runs at 2.1 GHz with 12 cores and a 3.3 GHz turbo frequency. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. It targets enterprises running virtualisation, databases or analytics workloads that demand high core counts and large memory capacity.

Installation notes and common issues

The chassis accepts 24 hot-swap 2.5-inch drive trays for SAS or SATA devices and ships with rails and a front bezel for rack mounting. Two redundant 1400 W platinum power supplies support hot-swap replacement. The PERC H755 RAID controller with 8 GB NV cache and battery enables RAID 0, 1, 5, 6, 10, 50 and 60. Installers must verify rack depth and power-phase compatibility before deployment; the server supports a maximum of two processors, so no further CPU expansion is possible.

24-bay 2.5-inch storage capacity

The defining specification is the 24-bay 2.5-inch front panel, which determines how many SAS or SATA drives can be installed without additional enclosures. This density suits workloads that prioritise drive count over individual drive capacity. Buyers needing 3.5-inch drives, NVMe-only configurations or more than 24 front-accessible bays should consider a different chassis.

Questions about this item

How do I verify both Xeon Silver 4310 CPUs and 256GB DDR4 are recognised after first boot?

Enter the iDRAC9 Enterprise web interface or BIOS setup and confirm two processors show 12 cores each at 2.1 GHz with 3.3 GHz turbo, and that 256 GB registered ECC memory at 2666 MHz is reported across the 32 DIMM slots.

Which components ship inside the 2U chassis and which must I source separately?

The box contains the R750 2U chassis, 2x Xeon Silver 4310 processors, 8x 32 GB DDR4 RDIMMs, PERC H755 RAID card with 8 GB NV cache, 24x 2.5" drive trays, Broadcom 57412 dual 10 GbE SFP+ OCP 3.0 card, iDRAC9 Enterprise, 2x 1400 W platinum PSUs, bezel and ready rails; drives and SFP+ modules are not included.

Should I choose the 24-bay 2.5" version or a 3.5" variant for this R750?

This specific unit is the 24-bay 2.5" SAS/SATA configuration; if your workload needs 3.5" drives you would need a different R750 chassis variant, as the backplane and trays are not interchangeable.
