Dell PowerEdge R650xs 1U Rack Server

The Dell PowerEdge R650xs is a 1U rack server built for dense data centre deployments. It operates with two Intel Xeon Silver 4316 processors running at 2.3GHz with 3.4GHz turbo. The system includes 128GB of DDR4 2666MHz registered ECC memory across eight modules. Ten 600GB 10K SAS drives connect through a PERC H745 controller with 4GB NV cache.

Suited For Virtualisation And Dense Compute

This server suits teams running virtualisation, cloud infrastructure or high-performance computing in a 1U form factor. Dual 1400W platinum power supplies and iDRAC9 Enterprise provide redundancy and remote management. Buyers who need GPU acceleration for AI workloads should note this unit ships without GPU hardware. Those requiring larger 3.5inch drive bays or more than ten 2.5inch slots must choose a different chassis.

PERC H745 RAID Controller With 4GB Cache

The Dell PERC H745 front RAID controller is the key storage component. It supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 4GB non-volatile cache and battery backup. This determines the data protection and performance profile for the ten installed 600GB SAS drives. The controller also manages any additional SAS, SATA or NVMe drives added to the remaining bays.

Questions about this item

How do I install the 10x 600GB SAS drives into the 2.5" bays and which step is commonly missed?

Slide each drive into the front 2.5" bays until the latch clicks; the step often missed is creating the virtual disks in the H745 controller BIOS before the OS sees any volume.

What maintenance will the H745 RAID controller's 4GB NV cache battery require later?

The cache battery is a replaceable module; plan to swap it every 3 to 5 years or when iDRAC9 reports a degraded state to keep write-back caching active.

What thermal or power limit appears first when both Xeon Silver 4316 CPUs run at 3.4GHz Turbo under sustained load?

The 1400W Platinum PSUs set the ceiling; prolonged all-core turbo can push total draw near the redundant supply rating, triggering throttling before the 1U chassis airflow limit is reached.
