PowerEdge R650xs 1U rack server

The Dell PowerEdge R650xs is a 1U rack server built for data centre workloads that demand high compute density. It ships with two Intel Xeon Silver 4316 processors running at 2.3 GHz, each providing 20 cores for parallel processing. The system includes 256 GB of DDR4 registered ECC memory and a PERC H745 RAID controller with 4 GB NV cache. Dual 1400 W platinum power supplies and a quad-port 1 GbE OCP 3.0 card complete the configured platform.

Ideal for virtualisation and dense compute.

This server suits teams running virtualisation clusters, cloud infrastructure or high-performance computing where CPU core count and memory reliability matter. The single 1U chassis and eight 2.5-inch drive bays support SATA and SAS media for mixed storage tiers. Buyers who need GPU acceleration for AI training or inference should look elsewhere, as this unit ships without GPU hardware or the optional GPU riser. The installed quad-port 1 GbE adapter also limits throughput for environments that require 10 GbE or 25 GbE networking out of the box.

Eight 2.5-inch bays with SATA/SAS RAID

The storage subsystem centres on eight front-accessible 2.5-inch trays connected to the PERC H745 controller, which supports RAID 0, 1, 5, 6, 10, 50 and 60 across SATA and SAS drives. This bay count and controller combination determines how many drives you can deploy and which redundancy schemes are available. Memory capacity reaches 1 TB across 16 DDR4 slots, but the storage interface and bay quantity are the fixed constraints that define whether this chassis matches your capacity and redundancy plan.

Questions about this item

How much power do the dual 1400 Watt Platinum supplies draw when the R650xs runs at full load all day?

Each supply is rated at 1400 Watts with Platinum efficiency; the server uses redundant hot-swap power so one unit can carry the full load if the other fails.

Which memory modules must already be installed for the 256 GB DDR4 configuration to operate?

The system ships with eight 32 GB DDR4 2666 MHz registered ECC DIMMs filling the required slots for the dual-processor layout.

Can the PERC H745 controller manage the existing 2.5-inch SAS and SATA drives from an older PowerEdge?

Yes, the H745 supports RAID 0, 1, 5, 6, 10, 50 and 60 on both SAS and SATA 2.5-inch drives installed in the eight front trays.
