Built for enterprise workloads

The PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Gold 6338 processors, each running at 2.0 GHz with 32 cores. It ships with 768 GB of DDR4 registered ECC memory across 24 modules. The system targets organisations running databases, virtualisation clusters and analytics platforms that demand high core counts and large memory capacity.

Storage interface limits

The integrated PERC H755 RAID controller manages up to 24 front-accessible 2.5-inch drive bays using SATA or SAS protocols. It supports RAID levels 0, 1, 5, 6, 10, 50 and 60 with 8 GB of non-volatile cache backed by a battery. NVMe drives are not supported by this controller, so high-speed flash must use the SAS or SATA interface.

Memory and expansion headroom

The platform provides 32 DDR4 slots in total, leaving eight slots free for future upgrades beyond the installed 768 GB. Two processors are already at the maximum socket count, so compute scaling requires a platform change. Dual 1400 W platinum power supplies deliver redundant hot-swap power for the current configuration.

Questions about this item

Should I choose the 768 GB configuration or add more DDR4 modules later?

The server ships with 768 GB across 24 of 32 DDR4 slots, leaving 8 slots open for future expansion if workloads grow.

What does the 3.2 GHz turbo speed deliver in daily use?

Each Gold 6338 core can boost to 3.2 GHz for short bursts, accelerating single-threaded tasks such as database indexing or compilation.

How does the OCP 3.0 10 GbE card limit real-world throughput?

The Broadcom 57412 dual-port SFP+ adapter caps network traffic at 10 Gb/s per port, so aggregate bandwidth tops out at 20 Gb/s.
