Compact 1U Rack Server for Dense Compute

The Dell PowerEdge R650xs is a 1U rackmount server system built on the 15th Generation PowerEdge platform. It ships with two Intel Xeon Silver 4316 processors running at 2.3 GHz with a 3.4 GHz turbo frequency, providing 20 cores each for a total of 40 cores. The chassis includes 128 GB of DDR4 2666 MHz registered ECC memory across eight 16 GB modules, a PERC H745 RAID controller with 4 GB NV cache, and eight 600 GB 10K SAS drives in 2.5 inch bays.

Suited for Virtualisation and Cloud Workloads

This configuration targets environments that need high core density and redundant power in a single rack unit, such as virtualisation clusters, cloud infrastructure nodes, or dense data analytics. The quad-port 1 GbE OCP 3.0 adapter and iDRAC9 Enterprise provide baseline connectivity and remote management. Buyers who require GPU acceleration, higher-speed networking, or NVMe boot drives should consider platforms that support those options.

Dual Xeon Silver 4316

The decisive specification is the pairing of two 20-core Xeon Silver 4316 CPUs with 128 GB of DDR4 memory and the eight 600 GB SAS drives behind the H745 controller. This combination fixes the compute, memory capacity, and storage throughput available without further upgrades. Verify that the LGA 4189 socket, DDR4 memory generation, and SAS interface match your infrastructure requirements before ordering.

Questions about this item

What rack height does the 1U R650xs require for mounting?

The server occupies 1U of rack space and ships with Ready Rails for installation in a standard rack cabinet.

How are the 2.5-inch SAS drives installed in the front bays, and what step is often missed?

Drives slide into the eight front-accessible bays and connect to the PERC H745 controller; the RAID array must be configured in the controller BIOS before the operating system sees any volumes.

When will the 1400W power supplies or the H745 controller battery need replacement?

The hot-swap 1400W units can be replaced individually without downtime; the H745 controller includes a battery-backed cache module that typically requires replacement after several years of service.
