PowerEdge R650xs 1U Server for Dense Compute

The Dell PowerEdge R650xs is a 1U rack server built on the 15G platform. It ships with two Intel Xeon Silver 4314 processors, each running at 2.4 GHz with 16 cores. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight DIMM slots. Dual 1400 W platinum power supplies provide redundant hot-swap power.

Ideal for Virtualisation and Cloud Workloads

This configuration suits teams deploying virtualisation, cloud infrastructure or high-performance computing in space-constrained racks. The PERC H745 controller with 4 GB NV cache supports RAID 0, 1, 5, 6, 10, 50 and 60 across eight 2.5-inch SAS or SATA trays. Buyers who need GPU acceleration for AI training or who require NVMe drive bays should evaluate other models.

Dual Xeon Silver 4314 16-Core CPUs Define Capacity

The two installed Silver 4314 processors deliver 32 total cores with a 3.4 GHz turbo frequency. This core count and clock speed set the performance ceiling for the server. Memory can expand to 1 TB using the remaining DDR4 slots. The LGA 4189 socket and 15G architecture determine future processor upgrade options.

Questions about this item

How do I install the Dell PERC H745 RAID controller and what step is often missed?

The H745 controller installs in the dedicated front storage slot; the step often missed is connecting the 4 GB NV cache battery cable before closing the chassis.

Which components will need replacement first during the server's lifespan?

The two 1400 W platinum power supplies and the PERC H745 cache battery are the primary field-replaceable units that typically require replacement over time.

What thermal or power limit appears first when both Xeon Silver 4314 CPUs run at 3.4 GHz turbo under sustained load?

The 1400 W redundant power supply rating is the first hard limit reached when both 16-core processors maintain 3.4 GHz turbo continuously.
