Enterprise 2U rack server

The Dell PowerEdge R750 is a 2U rack server built for data-intensive enterprise workloads. Two Intel Xeon Gold 6338 processors provide 32 cores each at 2.0 GHz with 3.2 GHz turbo. 512 GB of DDR4 3200 MHz registered ECC memory fills 16 of the 32 available slots. The PERC H755 RAID controller with 8 GB NV cache manages 24 SAS drives.

Upgrades from smaller 2U configurations

This configuration replaces deployments that relied on fewer cores, less memory or smaller drive counts. The jump is worth it when workloads demand simultaneous multi-threaded compute, large in-memory datasets and high-capacity 10K SAS storage in a single 2U chassis. Buyers who need GPU acceleration or all-flash NVMe arrays will find those capabilities absent here.

Installation notes

The server ships with ready rails and a front bezel for standard rack mounting. Dual 1400 W platinum power supplies and the PERC H755 controller are hot-swap redundant. Common issues include verifying backplane cabling for all 24 bays, confirming the iDRAC9 Enterprise licence is activated, and ensuring the OCP 3.0 quad-port 1 GbE card is seated before first boot.

Questions about this item

What rack depth clearance is needed for the ready rails included with the R750?

The ready rails supplied with the server mount in a standard 2U opening; ensure the cabinet depth allows the full chassis length plus cable bend radius at the rear.

What is the correct order for seating the 16 DDR4 DIMMs across the 32 slots?

Populate the memory slots per the processor-specific DIMM population sequence shown on the system board label, balancing channels evenly across both CPUs.

How often should the PERC H755 RAID controller battery be checked?

The H755 battery backs the 8GB NV cache; run the controller firmware health check quarterly and replace the battery when the iDRAC9 Enterprise log reports a degradation alert.
