DELL PowerEdge R650xs 1U Rack Server 2x Xeon Silver 4316 2.3GHz 20 Core 256GB DDR4 H745 10x 600GB SAS

Compact 1U rack server for dense compute

The Dell PowerEdge R650xs is a 1U rack server built for data-center density. It ships with two Intel Xeon Silver 4316 processors at 2.3 GHz, each offering 20 cores and a 3.4 GHz turbo frequency. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules and ten 600 GB 10K SAS drives managed by a PERC H745 RAID controller with 4 GB cache. Dual 1400 W platinum power supplies and iDRAC9 Enterprise provide redundant power and remote management out of the box.

Storage and memory limits to plan around

The chassis holds ten 2.5-inch drive bays connected to a SAS 12 Gb/s backplane through the H745 controller, which supports RAID 0, 1, 5, 6, 10, 50 and 60. Memory capacity tops out at 1 TB across sixteen DDR4 DIMM slots running up to 3200 MT/s, so the current 256 GB configuration leaves room for expansion. Network connectivity comes from a quad-port 1 GbE OCP 3.0 card, limiting aggregate throughput to 4 Gb/s unless additional adapters are installed.

Compatibility checks before ordering

Verify that your rack provides standard 1U spacing and sufficient depth for the included sliding rails, and that your PDU can deliver two independent 1400 W feeds with the correct IEC connectors. Confirm that your hypervisor or operating system supports the Xeon Silver 4316 LGA 4189 platform and the PERC H745 RAID stack. Ensure the SAS drives match your existing storage topology, as they are not interchangeable with SATA or NVMe media without a different backplane.
