Compact 1U server with dual Xeon Silver 4314 CPUs

The Dell PowerEdge R650xs is a 1U rack server equipped with two Intel Xeon Silver 4314 processors. Each CPU provides 16 cores at a base speed of 2.4 GHz and a turbo frequency of 3.4 GHz. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. It is built for dense virtualization, cloud infrastructure and high-performance computing workloads.

Suited for dense compute clusters.

This server suits organisations that need high core counts in a single rack unit for virtualisation or database tasks. The dual 1400 W platinum power supplies and redundant hot-swap design support continuous operation. Buyers who require internal GPU acceleration for AI training or inferencing should look elsewhere, as the 1U chassis does not accommodate full-height accelerator cards. The eight 2.5-inch drive trays limit internal storage device count compared to larger form factors.

H745 RAID controller with 4 GB NV cache

The Dell PERC H745 front RAID controller manages the eight 2.5-inch SAS and SATA drive bays. It supports RAID levels 0, 1, 5, 6, 10, 50 and 60 with 4 GB of non-volatile cache backed by a battery. This controller determines the storage performance and data protection capabilities available to the installed drives. Maximum system memory capacity reaches 1 TB across 16 DDR4 DIMM slots.

Questions about this item

Which configuration should I choose between the installed 256GB DDR4 and the maximum 1TB capacity?

The system ships with 256GB (8x 32GB) DDR4 2666MHz registered ECC. The platform supports up to 1TB across 16 DIMM slots at 3200 MT/s, so you can add modules later if workloads grow.

What does the 2.4GHz base clock with 3.4GHz turbo mean for actual throughput on the dual Xeon Silver 4314?

Two Silver 4314 CPUs provide 32 total cores at 2.4GHz base. Under load they can reach 3.4GHz turbo, giving strong multi-thread performance for virtualization and dense compute in the 1U form factor.

How does the OCP 3.0 10GbE SFP+ card and PERC H745 controller limit real-world I/O?

The Broadcom 57412 dual-port 10GbE SFP+ OCP 3.0 adapter caps network throughput at 10Gb/s per port. The H745 RAID controller with 4GB NV cache handles SAS/SATA drives at 12Gb/s per lane, supporting RAID 0/1/5/6/10/50/60.
