Dual 20-core Xeon 1U server

The Dell PowerEdge R650xs is a 1U rack server built for dense compute workloads. It ships with two Intel Xeon Silver 4316 processors running at 2.3 GHz with a 3.4 GHz turbo. Each CPU provides 20 cores for a total of 40 threads. The platform targets virtualization, cloud infrastructure and high-performance computing.

128 GB DDR4 registered ECC memory

The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight 16 GB modules. The board supports up to 1 TB maximum capacity across 16 DIMM slots running at speeds up to 3200 MT/s. This configuration suits memory-intensive applications that require error correction.

Eight 2.5-inch drive bays with H745 RAID

Front-access trays accept eight 2.5-inch SAS or SATA drives managed by a PERC H745 controller with 4 GB NV cache and battery. The controller supports RAID 0, 1, 5, 6, 10, 50 and 60. Dual 1400 W platinum power supplies and a quad-port 1 GbE OCP 3.0 card provide redundant power and network connectivity. iDRAC9 Enterprise enables remote management.

Questions about this item

How do the two 20-core Xeon Silver 4316 processors at 2.3 GHz perform under sustained load in a 1U chassis?

Each CPU runs at 2.3 GHz base with 3.4 GHz turbo across 20 cores. The 1U form factor uses front-to-back airflow and dual 1400 W platinum supplies to maintain thermal headroom during continuous multi-threaded workloads such as virtualization or database serving.

What RAID levels and cache protection does the PERC H745 controller provide for the eight 2.5-inch drive bays?

The H745 supports RAID 0, 1, 5, 6, 10, 50 and 60 with 4 GB of non-volatile cache backed by a battery, so write acceleration and data integrity are preserved across unexpected power loss on any mix of SAS or SATA drives.

What physical mounting hardware is included for installing the 1U server into a rack?

The shipment includes Dell Ready Rails sliding rails and a front bezel. The rails mount to standard square-hole or threaded 4-post racks and allow tool-less installation of the 1U chassis.
