Dell PowerEdge R750 2U Rack Server

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads that demand high core counts and large memory capacity. It ships with two Intel Xeon Gold 6338 processors, each offering 32 cores at 2.0 GHz with a 3.2 GHz turbo frequency. The system includes 256 GB of DDR4 3200 MHz registered ECC memory across eight 32 GB modules. This configuration targets database, virtualisation and analytics environments.

Dual 1400 W Platinum Power Supplies

Redundant hot-swap power supplies rated at 1400 W each deliver platinum efficiency under normal load. The 2U chassis uses Dell's 15th generation thermal design to move air across the dual CPU sockets, 32 DIMM slots and 24 drive bays. Fan speeds adjust dynamically to maintain component temperatures while keeping acoustic output suitable for data centre aisles.

PERC H755 RAID Controller with NV Cache

The Dell PERC H755 PCIe controller adds 8 GB of non-volatile cache backed by a battery, enabling RAID 0, 1, 5, 6, 10, 50 and 60 across the 24 installed 1.92 TB SATA SSDs. iDRAC 9 Enterprise provides out-of-band remote management with a dedicated lifecycle controller. A Broadcom 5720 quad-port 1 GbE OCP 3.0 card supplies network connectivity, while ready rails and a front bezel simplify rack integration.

Questions about this item

How do I install the 24x 1.92TB SATA SSDs into the 2.5-inch bays of the PowerEdge R750?

Slide each drive into a front-accessible 2.5-inch bay until the latch clicks; the common mistake is not fully seating the drive so the controller does not detect it.

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

The battery backs the cache during power loss; it typically needs replacement every three to five years to maintain write-back caching protection.

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

The 1400W platinum power supplies set the ceiling; prolonged all-core turbo can hit their thermal and current limits before CPU throttling activates.
