Dell PowerEdge R650xs 1U Rack Server

The Dell PowerEdge R650xs is a new 1U rack server built for dense compute environments. It operates with two Intel Xeon Gold 6338 processors, each delivering 32 cores at a base frequency of 2.0 GHz with 3.2 GHz turbo. The system includes 64 GB of DDR4 3200 MHz registered ECC memory across four 16 GB modules. Dual 1400 W platinum power supplies provide redundant hot-swap power.

Suited for virtualization and high-density workloads

This server suits organisations deploying virtualization, cloud infrastructure, or data analytics in a 1U footprint. Eight 2.5-inch drive bays and the PERC H745 controller with 4 GB NV cache support SAS, SATA, and NVMe drives for flexible storage tiers. Quad-port 1 GbE OCP 3.0 networking and iDRAC9 Enterprise simplify deployment. Buyers needing GPU acceleration for AI training or more than 1 TB of memory should evaluate other platforms.

Dual Xeon Gold 6338 32-core processors

The decisive specification is the pair of Intel Xeon Gold 6338 CPUs, providing 64 total cores in a single 1U chassis. This density determines whether the server matches the compute-per-rack-unit target for the intended workload. Memory scales to 1 TB across 16 DDR4 slots, and the LGA 4189 socket limits upgrades to compatible 3rd Gen Intel Xeon Scalable processors.

Questions about this item

Should I choose the 64 GB DDR4 3200 MHz configuration or add more modules up to 1 TB?

The system ships with 64 GB in four 16 GB DDR4 3200 MHz registered ECC modules across 16 slots, so you can expand later up to the 1 TB maximum without replacing the original sticks.

What does the 2.0 GHz base and 3.2 GHz turbo on the dual Xeon Gold 6338 32-core CPUs mean for sustained workloads?

Each processor runs at 2.0 GHz base and can boost to 3.2 GHz; with 64 total cores across both sockets the server maintains high throughput for virtualization and dense compute tasks while staying within the 1U power envelope.

How does the PERC H745 controller with 4 GB NV cache and the 12 Gb/s SAS drives limit real-world array speed?

The H745 supports RAID 0/1/5/6/10/50/60 and its 4 GB non-volatile cache accelerates write performance, while the eight 600 GB 10K SAS drives at 12 Gb/s set the maximum sustained throughput for the array.
