PowerEdge R650xs 1U Server
The Dell PowerEdge R650xs is a 1U rack server fitted with two Intel Xeon Silver 4314 processors, each running at 2.4 GHz with 16 cores. It includes 256 GB of DDR4 2666 MHz registered ECC memory across eight modules. A Dell PERC H745 RAID controller with 4 GB NV cache manages ten 1.8 TB 10K SAS drives. Dual 1400 W platinum power supplies and iDRAC9 Enterprise complete the package.
Virtualisation and dense compute workloads
This server suits teams running virtualised infrastructure, cloud platforms or high-performance analytics where CPU core count and fast SAS storage matter. The 1U form factor and dual 10 GbE SFP+ ports help maximise rack density. Buyers who need GPU acceleration for AI training or larger NVMe capacity should evaluate other configurations, as this unit ships without GPU support and uses SAS hard drives rather than solid-state storage.
PERC H745 RAID with 4 GB NV cache
The storage controller supports RAID 0, 1, 5, 6, 10, 50 and 60, with battery-backed cache protecting writes during power loss. This specification determines whether the array can meet your redundancy and performance targets for the installed 1.8 TB SAS drives.

Questions about this item
How do I install the 10x 1.8TB SAS drives into the 2.5" front bays, and what step is often missed?
Slide each drive into a bay until the lever clicks, then open iDRAC 9 Enterprise and create virtual disks on the PERC H745 controller — the array will not appear to the OS until the RAID set is configured.
Which components will need replacement first, and on what schedule?
The 10K SAS drives and the PERC H745 battery-backed cache module are the primary wear items; plan drive refreshes every three to five years and cache battery replacement when iDRAC reports degradation.
What limit appears first when both Xeon Silver 4314 processors run sustained heavy workloads?
The 1400 W platinum power supplies and 1U chassis airflow set the practical ceiling; CPU turbo drops from 3.4 GHz toward 2.4 GHz once the thermal budget is reached.
