Dual Xeon Silver 4316 1U Server

The Dell PowerEdge R650xs is a 1U rack server equipped with two Intel Xeon Silver 4316 processors running at 2.3 GHz with a 3.4 GHz turbo frequency. Each CPU provides 20 cores for a total of 40 cores, targeting virtualisation, cloud infrastructure and dense data-analytics workloads. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots and supports up to 1 TB maximum capacity.

Sustained Load Behaviour

Under continuous demand the dual 20-core processors maintain high throughput for multi-threaded applications such as hypervisor hosts and analytics clusters. The PERC H745 RAID controller with 4 GB NV cache and battery backup sustains write performance across RAID 0, 1, 5, 6, 10, 50 and 60 without data-loss risk during power interruption. Eight 1.92 TB SATA SSDs deliver consistent read bandwidth for database and content-delivery tasks.

Thermals, Noise and Power

Two 1400 W platinum-efficiency hot-swap power supplies provide redundancy and high conversion efficiency during normal operation. The 1U chassis uses Dell's thermal design to manage heat from both CPUs, memory and storage while keeping acoustic output within typical data-centre limits. iDRAC 9 Enterprise enables remote monitoring of temperatures, fan speeds and power draw without requiring physical access.

Questions about this item

How much power do the dual 1400 W supplies draw when the 2.3 GHz Xeons run continuously?

The server includes two 1400 W platinum-efficiency power supplies with hot-swap redundancy; exact idle and full-load draw depends on workload and inlet temperature.

Which rack standard do the included Ready Rails mount to?

The supplied Ready Rails are designed for standard square-hole and round-hole 4-post racks; threaded-hole racks need a separate adapter kit.

Will the PERC H745 controller recognise my existing SAS drives?

The H745 supports SAS, SATA and NVMe drives; legacy SAS disks that meet the controller's firmware compatibility list will be detected.
