PowerEdge R750 2U 24-bay server

The Dell PowerEdge R750 is a 2U rackmount server equipped with two Intel Xeon Silver 4316 processors running at 2.3 GHz with 20 cores each. It ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules. The system includes a PERC H755 RAID controller with 8 GB NV cache and battery backup. Twenty-four 960 GB SATA solid-state drives are pre-installed in the 2.5-inch drive bays.

Installation and common issues

The server arrives with ready rails and a front bezel for standard rack mounting. Hot-swap power supplies and drive carriers simplify hardware replacement without downtime. The LGA 4189 socket and 32 DIMM slots require careful alignment during any processor or memory upgrades. Builders who need 3.5-inch drive support or more than two processors will find the 24-bay 2.5-inch chassis and dual-socket limit restrictive.

Capacity and headroom

The dual 20-core CPUs and 128 GB DDR4 handle virtualisation, databases and analytics workloads with ample thread count and memory bandwidth. The H755 controller supports RAID 0, 1, 5, 6, 10, 50 and 60 across the 24 SATA SSDs for flexible redundancy and performance tuning. Dual 10 GbE SFP+ ports and iDRAC 9 Enterprise provide high-speed connectivity and remote management. Workloads demanding more than 24 drive bays, NVMe-only storage or memory beyond the installed 128 GB will exceed this configuration.

Questions about this item

How do I verify the PERC H755 RAID controller is operating correctly after initial configuration?

During POST the controller initialises and displays its firmware version; once the OS loads, the iDRAC9 Enterprise interface shows the H755 with 8GB NV cache and battery status, and the RAID 0/1/5/6/10/50/60 virtual disks report optimal health.

Which components are included and which must be purchased separately for this R750?

The unit ships with two Xeon Silver 4316 20-core CPUs, 128GB (8x 16GB) DDR4 2666MHz ECC RDIMMs, PERC H755 with 8GB NV cache, 24x 960GB SATA SSDs, Broadcom 57412 dual-port 10GbE SFP+ OCP 3.0 card, iDRAC9 Enterprise, two 1400W platinum PSUs, Ready Rails and front bezel. Additional DDR4 DIMMs, drives or GPU cards are not included.

Which memory capacity should I choose if I need room to grow beyond the installed 128GB?

The server has 32 DDR4 slots; 8 are populated with 16GB modules for 128GB total. To expand, add matching 16GB or 32GB DDR4 2666MHz ECC RDIMMs in the remaining 24 slots up to the platform maximum.
