DELL PowerEdge R650xs 1U rack server 2x Xeon Silver 4316 2.3GHz 20C 128GB DDR4 10x 1.92TB SATA H745 1400W

Dense 1U compute node

The Dell PowerEdge R650xs packs two Intel Xeon Silver 4316 processors, each with 20 cores running at 2.3 GHz and a 3.4 GHz turbo frequency, into a single rack unit. Eight 16 GB DDR4 registered ECC modules provide 128 GB of memory at 2666 MT/s. A PERC H745 controller with 4 GB NV cache manages ten 1.92 TB SATA solid-state drives across RAID levels 0, 1, 5, 6, 10, 50 and 60. Dual 1400 W platinum power supplies and iDRAC9 Enterprise complete the package.

Sustained throughput focus

The dual-socket design distributes 40 total cores across parallel workloads such as virtualization clusters, database nodes and dense analytics jobs. Registered ECC memory corrects single-bit errors without halting the system during long-running tasks. The H745 controller’s battery-backed cache absorbs write bursts and preserves data integrity if power fluctuates. Ten SATA SSDs deliver consistent read latency for mixed random-access patterns typical of hyper-converged infrastructure.

Verify rack depth and network optics

This 1U chassis requires a four-post rack with sufficient depth for the included sliding rails and front bezel. The OCP 3.0 mezzanine card provides two 10 GbE SFP+ ports, so compatible transceivers and cabling must be sourced separately. Confirm that the facility power circuits can support dual 1400 W supplies at the available voltage. The system supports up to 1 TB of DDR4 memory across 16 DIMM slots if future expansion is planned.
