Dual 32-Core 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 and a 3.2 GHz turbo frequency. It ships with 64 GB of DDR4 3200 MHz registered ECC memory across four 16 GB modules. The system targets enterprises running virtualisation, databases or analytics workloads that demand high core counts and large memory capacity in a compact rack footprint.

Redundant 1400 W Platinum Power Supplies

Two hot-swap 1400 W platinum-efficiency power supplies provide full redundancy and handle peak loads from both CPUs, memory, storage and networking. The 2U chassis uses Dell's engineered airflow path to cool dual high-wattage processors and 24 drive bays without excessive fan speed. In typical operation the redundant design keeps the server running even if one supply fails or is removed for maintenance.

24-Bay Front Storage with PERC H755 RAID

The front panel holds 24 hot-swap 2.5-inch trays accepting SAS or SATA drives, while a Dell PERC H755 controller with 8 GB NV cache and battery backs RAID 0, 1, 5, 6, 10, 50 and 60. A Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 card handles high-speed networking. iDRAC 9 Enterprise gives full remote management, and ready rails plus a front bezel simplify rack installation. Buyers needing 3.5-inch drives or NVMe-only bays should verify chassis compatibility before ordering.

Perguntas sobre este artigo

How do I install the 2.5" drives into the 24 front bays and which step is often missed?

Slide each drive into a tray until it clicks, insert the tray into the bay until the latch engages, then verify the PERC H755 controller sees every drive in its BIOS before creating RAID volumes.

What maintenance will the H755 RAID controller's 8GB NV cache battery require later?

The cache battery is a replaceable module; plan to swap it every 3–5 years or when iDRAC 9 Enterprise reports a degraded state to avoid write-cache loss during power events.

What thermal or power limit appears first when both Xeon Gold 6338 CPUs run at 3.2 GHz turbo under sustained load?

The dual 1400 W platinum PSUs and 2U airflow design set the ceiling; prolonged all-core turbo will hit the chassis thermal envelope before the power budget is exhausted.
