DELL PowerEdge R650 1U rack server 2x Xeon Gold 6338 2.0GHz 32 Core 128GB DDR4 10x 1.8TB SAS H755 2x 1400W PSU

Dual 32-Core Xeon Gold 6338 1U Server

The Dell PowerEdge R650 is a 1U rack server equipped with two Intel Xeon Gold 6338 processors, each running at 2.0 GHz with 32 cores. It ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules. The system includes a PERC H755 RAID controller with 8 GB NV cache and ten 1.8 TB 10K SAS drives. Dual 1400 W platinum power supplies provide redundancy.

SAS 12 Gb/s storage and PCIe Gen4 limits

The server uses a 12 Gb/s SAS interface for its ten 2.5-inch drive bays, which caps sequential throughput at the drive and controller level. PCIe Gen4 lanes are available for add-in cards, but the installed PERC H755 controller and SAS backplane define the practical bandwidth ceiling for the included storage. The OCP 3.0 network adapter occupies one high-speed slot, leaving remaining PCIe lanes for expansion.

128 GB DDR4 installed versus 2 TB maximum

The system arrives with 128 GB of DDR4 3200 MHz memory installed in eight slots, leaving significant headroom up to the 2 TB maximum capacity. Buyers who need more memory for large-scale virtualization or in-memory databases must populate additional DIMM slots with compatible registered ECC modules. The 32-core processor count supports heavy threading, but memory capacity per core depends on the final configuration.
