Dual-socket Xeon Gold 6338 server

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Gold 6338 processors, each running at 2.0 GHz with 32 cores. The system includes 512 GB of DDR4 memory across 16 modules and a PERC H755 RAID controller with 8 GB NV cache. It targets enterprises running databases, virtualization, or high-performance computing workloads that demand high core counts and large memory capacity.

Tool-less rails and hot-swap components

The server ships with ready rails and a front bezel for straightforward rack mounting. Twenty-four 2.5-inch drive trays support hot-swap SATA and SAS drives, while dual 1400 W platinum power supplies provide redundant hot-swap power. Common issues include verifying that the H755 controller firmware matches the drive firmware and ensuring the iDRAC9 Enterprise licence is activated for full remote management.

Confirm rack depth and network cabling

Before ordering, check that your rack depth accommodates a 2U chassis with cable management arms. The OCP 3.0 network card uses dual 10 GbE SFP+ ports, so compatible transceivers and patch cables must be sourced separately. Ensure the facility power circuits can deliver sufficient current for two 1400 W supplies operating at peak load.

Questions about this item

How do I verify the PERC H755 controller is operating correctly after installation?

The H755 controller has 8GB NV cache and battery; check its BIOS during boot or iDRAC9 Enterprise to confirm RAID 0/1/5/6/10/50/60 arrays are optimal and cache is active.

What ships with the server and what must I add before use?

Included: 2x Xeon Gold 6338 2.0GHz 32-core CPUs, 512GB DDR4 (16x 32GB 3200MHz ECC), H755 controller, 24x 2.5" trays, Broadcom 57412 dual 10GbE SFP+ OCP 3.0 card, iDRAC9 Enterprise, 2x 1400W PSUs, rails, bezel. Drives sold separately.

Which memory configuration matches the 512GB DDR4 spec listed?

The 512GB total is built from 16 modules of 32GB DDR4 3200MHz registered ECC, leaving 16 of the 32 slots free for future expansion up to the platform limit.
