Compact 1U rack server for dense compute

The Dell PowerEdge R650 is a 1U rack server built on the 15th Generation PowerEdge platform. It ships with two Intel Xeon Silver 4316 20-core processors running at 2.3 GHz with 3.4 GHz turbo. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight 16 GB modules. Dual 1400 W platinum power supplies provide redundant hot-swap power.

Storage flexibility decided by 10-bay 2.5" chassis

The front panel holds ten 2.5-inch SAS/SATA drive trays backed by a Dell PERC H755 RAID controller with 8 GB NV cache and battery. The controller supports RAID 0, 1, 5, 6, 10, 50 and 60. The platform also supports NVMe drives for workloads that need faster storage throughput. The OCP 3.0 quad-port 1 GbE network adapter handles connectivity.

Suits virtualisation and private cloud.

This configuration targets virtualisation, database management and dense private cloud deployments where CPU density and memory capacity matter. It lacks GPU support and AI-specific acceleration, so buyers who need graphics compute or dedicated inference engines should look at platforms designed for accelerator cards. The iDRAC9 Enterprise module provides full remote management.

Questions about this item

How does the 2.3 GHz base clock on the Xeon 4316 behave under load in this 1U chassis?

The two Xeon Silver 4316 processors run at 2.3 GHz base and can reach 3.4 GHz turbo; actual sustained speed depends on workload, cooling headroom and the dual 1400 W power supplies.

What throughput does the Broadcom 5720 quad-port 1 GbE OCP 3.0 card deliver in practice?

The OCP 3.0 adapter provides four 1 GbE ports; each port is capped at 1 Gbps line rate, giving up to 4 Gbps aggregate through the PCIe Gen4 slot.

What physical space and mounting hardware does the 1U server need in a rack?

The unit occupies one rack unit of height and ships with ready rails and a front bezel for standard rack installation.
