Enterprise compute platform

The Dell PowerEdge R750 is a 2U rack server built for virtualization clusters and database workloads that demand dual-socket density. Two Intel Xeon Silver 4316 processors provide 40 total cores at 2.3 GHz with 3.4 GHz turbo headroom for burst capacity.

HBA355i and 10 GbE OCP card

The PERC HBA355i presents 12 SAS/SATA bays as straight pass-through devices so administrators can implement software-defined storage or ZFS without hardware RAID abstraction. A Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 adapter supplies high-throughput networking for replication traffic.

Redundant power and remote management

Dual 1400 W platinum power supplies deliver hot-swap redundancy for continuous uptime in density-constrained racks. iDRAC 9 Enterprise enables full out-of-band control including virtual console and firmware orchestration across the fleet. Not suited for buyers who need integrated RAID acceleration or NVMe-only backplanes.

Questions about this item

What maintenance will the 24 DDR4 2666 MHz memory modules need?

The 768 GB is installed as 24 registered ECC DDR4 modules at 2666 MHz. They have no moving parts and require no scheduled replacement; a failed DIMM is swapped individually.

What limit appears first when both Xeon Silver 4316 20-core CPUs run sustained all-core workloads?

The dual 1400 W platinum power supplies set the sustained power ceiling; thermal limits are managed by the chassis fans before CPU throttling occurs.

How loud and hot does the 2U chassis get with 12 drives and dual 1400 W PSUs running continuously?

Redundant 1400 W platinum units and hot-swap fans keep the 2U enclosure within Dell thermal specs; noise is typical for a 12-bay rack server under load.
