PowerEdge R650xs 1U 8 Bay Server

The Dell PowerEdge R650xs is a 1U rack server built for dense compute environments. It ships with two Intel Xeon Silver 4314 processors, each with 16 cores running at 2.4 GHz and a 3.4 GHz turbo frequency. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. A PERC H745 controller with 4 GB NV cache manages up to eight 2.5 inch SAS or SATA drive trays.

Virtualisation and cloud hosts needing dual-socket

This server suits teams running virtualisation clusters, cloud infrastructure or high-performance analytics where dual 16-core CPUs and 256 GB of memory fit in a single rack unit. The quad-port 1 GbE OCP 3.0 card and iDRAC9 Enterprise simplify remote deployment at scale. Buyers who need GPU acceleration, 10 GbE or 25 GbE networking, or NVMe-only storage should look at other configurations because this unit ships with 1 GbE ports and SAS/SATA trays only.

PERC H745 RAID controller with 4 GB cache

The installed Dell PERC H745 front RAID controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a battery-backed 4 GB NV cache. This single component determines whether the server can deliver the write performance and data protection your workload requires. Verify that the supported RAID levels and cache size match your application before purchasing.

Questions about this item

Should I pick the single-processor or dual-processor version of the R650xs?

This unit ships with two Xeon Silver 4314 processors, giving 32 cores total. The board supports a maximum of two CPUs, so no further processor upgrade is possible.

What does the 2.4 GHz base clock mean for real-world throughput?

Each of the 32 cores runs at 2.4 GHz base and can turbo to 3.4 GHz, so heavily threaded workloads scale across all cores while burst tasks hit the higher frequency.

How does the OCP 3.0 slot with the 5720 quad-port card limit network speed?

The Broadcom 5720 provides four 1 GbE ports over an OCP 3.0 interface, capping each connection at 1 Gbps regardless of the slot’s higher potential bandwidth.
